The long-term urinary dysfunction after type C2 radical hysterectomy in patients with cervical cancer

Radical hysterectomy (RH) may cause lower urinary tract symptoms (LUTS) for patients with cervical cancer. Few data are available on the long-term LUTS of these patients and whether the symptoms relate to the route of surgery remain unclear. Here, we assessed the long-term urinary dysfunction in cervical cancer patients after RH based on a self-reported questionnaire. A total of 168 patients after type C2 RH, either by laparoscopy (LRH) or laparotomy (ARH), were analysed. The median length of follow-up was 54 ± 8.35 months. The total incidence of urinary dysfunction was around 40%. Patients with LRH had more intermittent stream and feeling of incomplete emptying than those in ARH group. Our data indicate the irreversible damage of RH to urinary function of cervical cancer patients, who should be informed of the long-term and high incidence of urinary dysfunction after RH when they choose surgical treatment.Impact Statement

Modifiable prognostic factors in uterine fibroid development: a systematic review of literature

Many risk factors in uterine fibroid development have been identified, but women and their physicians are less aware of the influence of lifestyle on uterine fibroid development. The objective of this systematic review is to investigate and summarize modifiable prognostic factors associated with uterine fibroid development. Pubmed and Embase were searched for relevant articles according to PRISMA guidelines. References from included articles were screened and when relevant also included. Human in vivo studies on modifiable factors in fibroid development were included. Studies on non-modifiable factors and treatment, in vitro studies and animal studies were excluded. 607 articles were screened and 33 articles were included. Two independent investigators collected data from the report. The strongest risk factor for fibroid development was a high BMI, while the strongest protective factors were a high fruit and vegetable intake and high vitamin D intake. More high-quality studies are necessary to better understand the impact of the abovementioned factors as well as the role they play in the growth of already existing fibroids.

Small molecule inhibitor of nicotinamide N-methyltransferase shows anti-proliferative activity in HeLa cells

The anti-proliferative effects of 5-methylquinolinium (5MQ) of nicotinamide N-methyltransferase (NNMT) have not been previously investigated on a cervical cancer cell line. NNMT is a metabolic enzyme that is correlated with tumour progression and metastasis. 5MQ is a small molecule inhibitor of NNMT. 0.1-500 μM of 5MQ was tested on the HeLa epithelial cervical cancer cell line. Cell viability was assessed with the MTT test.

Oncologic outcomes in older women with endometrial carcinoma (≥70 years)

Data are limited in the management of elderly women with endometrial cancer as they are under-represented in clinical trials. The aim of this study was to evaluate the outcomes of women ≥70 years who underwent hysterectomy. One hundred and twenty-one patients met the inclusion criteria. The median age among the cohort was 75 years (range: 70-91), and 52% underwent robotic surgery. The five-year overall survival (OS) rate was 67%. The five-year cumulative incidence of recurrence was 19%. Based on univariate analysis, white race, lower ASA score, higher pre-operative and post-operative haematocrit, lower estimated blood loss, stage I and robotic surgery were associated with improved OS. On multivariable analysis, ASA score, preoperative haematocrit, estimated blood loss and stage were associated with survival.Survival rates among older women were low and disease recurrence was high. Robotic surgery was safe and appeared to improve perioperative outcomes in older women with endometrial cancer.Impact Statement

Life quality of endometrioid endometrial cancer survivors: a cross-sectional study

Endometrial cancer is the most common gynaecologic malignancy in developed countries with increasing incidence worldwide. A total of 201 patients were enrolled and a cross-sectional study was performed using the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30) and Female Sexual Functioning Index (FSFI) after the approval by an institutional review board (University of Health Sciences, Tepecik Education and Research Hospital, Turkey, March 13, 2019, Approval no. 2019/4-27).

Consent model for tumour genetic testing in ovarian cancer

Prospective parallel genetic testing of both germline and tumour DNA in ovarian cancer patients (OC) is the recommended model in several different countries across the globe and the UK. The high (∼67%) chance of identifying germline PVs in patients with tumour PVs has led to a discourse surrounding the need for consent for tumour genetic testing in OC. We discussed with OC patients during focus group workshops, physicians, and charity representatives about consent options for tumour testing in OC patients: verbal consent prior to testing (Option 1) and reflex testing (Option 2). Most patients (97%; 33/34) did not feel that consent was required and were happy with reflex testing (Option 2). Physician consensus was that reflex testing was preferred and most charity representatives (4/5; 80%) agreed. All groups wanted an opt-out option and a patient information sheet about tumour testing. This can inform new recommendations in the UK and foster further discussions regarding consent for OC tumour testing.

Is there any benefit of paraaortic field irradiation in pelvic lymph node positive endometrial cancer patients? A propensity match analysis

We evaluated the survival outcomes and recurrence patterns of endometrial cancer (EC) patients with pelvic lymph node metastases who received postoperative radiotherapy (RT) to the pelvis (P-RT) or to the pelvis plus paraaortic lymph nodes (PA-RT) with or without systemic chemotherapy (ChT). The data from 167 patients with stage IIIC1 EC treated with postoperative RT or RT and ChT were collected retrospectively. Those patients with pelvic lymph node metastases were treated with either P-RT (106 patients, 63%) or PA-RT (61 patients, 37%). The median follow-up time for the entire cohort was 49 (range = 5-199) months. The patients receiving adjuvant ChT and RT had significantly higher 5-year OS rates (77% vs. 33%,

Effectiveness of oral etoposide in recurrent or refractory epithelial ovarian cancer, primary peritoneal cancer and fallopian tube cancer

The aim of treatment in recurrent or refractory epithelial ovarian cancer is palliation. In a patient with platinum-resistant status, several chemotherapy regimens have been reported with similar response rates. Among these agents, the oral etoposide holds an advantage of the route of administration and management in the out-patient setting. This retrospective study was conducted to evaluate the effectiveness of oral etoposide. Data of patients with recurrent or refractory epithelial ovarian, primary peritoneal and fallopian tube cancer who received oral etoposide treatment in Ramathibodi Hospital, Mahidol University from January 1997 to December 2017 were collected. Progression-free survival (PFS) and overall survival (OS) were primary and secondary outcomes, respectively. The oral etoposide at a dose of 50 mg/m

Scoring systems for the evaluation of adnexal masses nature: current knowledge and clinical applications

Adnexal masses are a common finding in women, with 20% of them developing at least one pelvic mass during their lifetime. There are more than 30 different subtypes of adnexal tumours, with multiple different subcategories, and the correct characterisation of the pelvic masses is of paramount importance to guide the correct management. On that basis, different algorithms and scoring systems have been developed to guide the clinical assessment. The first scoring system implemented into the clinical practice was the Risk of Malignancy Index, which combines ultrasound evaluation, menopausal status, and serum CA-125 levels. Today, current guidelines regarding female patients with adnexal masses include the application of International Ovarian Tumours Analysis simple rules, logistic regression model 1 (LR1) and LR2, OVERA, cancer ovarii non-invasive assessment of treating strategy, and assessment of Different Neoplasias in the adnexa. In this scenario, the choice of the scoring system for the discrimination between benign and malignant ovarian tumours can be complex when approaching patients with adnexal masses. This review aims to summarise the available evidence regarding the different scoring systems to provide a complete overview of the topic.

The long noncoding RNA CCDC144NL-AS1: prognosis significance and potential biological functions in cervical carcinoma

Recent research has shown that long noncoding RNA (lncRNA) performs a critical regulatory function across multiple malignancies. The involvement of RNA in the progression of multiple human cancer types has been elucidated; however, there is limited understanding regarding the importance of the lncRNA CCDC144NL-AS1 in cervical carcinoma (CC). CCDC144NL-AS1 expression was measured in 86 CC samples by RT-PCR. CC cell lines were engineered with CCDC144NL-AS1 overexpression using plasmid vectors, allowing for the exploration of its impact on the migration of tumour cells. Additionally, we studied how CCDC144NL-AS1 impacts epithelial-mesenchymal transition signalling, focusing on its expression levels and functional roles. CCDC144NL-AS1 expression showed a notable increase in gynaecological tumour specimens and cell lines in contrast to normal control (all CCDC144NL-AS1 significantly influences cell migration, making it a promising target for CC treatment and a valuable prognostic indicator.

The bioinfomatics analysis of the M1 macrophage-related gene CXCL9 signature in cervical cancer

The expression and function of coexpression genes of M1 macrophage in cervical cancer have not been identified. And the CXCL9-expressing tumour-associated macrophage has been poorly reported in cervical cancer. To clarify the regulatory gene network of M1 macrophage in cervical cancer, we downloaded gene expression profiles of cervical cancer patients in TCGA database to identify M1 macrophage coexpression genes. Then we constructed the protein-protein interaction networks by STRING database and performed functional enrichment analysis to investigate the biological effects of the coexpression genes. Next, we used multiple bioinformatics databases and experiments to overall investigate coexpression gene CXCL9, including western blot assay and immunohistochemistry assay, GeneMANIA, Kaplan-Meier Plotter, Xenashiny, TISCH2, ACLBI, HPA, TISIDB, GSCA and cBioPortal databases. There were 77 positive coexpression genes and 5 negative coexpression genes in M1 macrophage. The coexpression genes in M1 macrophage participated in the production and function of chemokines and chemokine receptors. Especially, CXCL9 was positively correlated with M1 macrophage infiltration levels in cervical cancer. CXCL9 expression would significantly decrease and high CXCL9 levels were linked to good prognosis in the cervical cancer tumour patients, it manifestly expressed in blood immune cells, and was positively related to immune checkpoints. CXCL9 amplification was the most common type of mutation. The CXCL9 gene interaction network could regulate immune-related signalling pathways, and CXCL9 amplification was the most common mutation type in cervical cancer. Meanwhile, CXCL9 may had clinical significance for the drug response in cervical cancer, possibly mediating resistance to chemotherapy and targeted drug therapy. Our findings may provide new insight into the M1 macrophage coexpression gene network and molecular mechanisms in cervical cancer, and indicated that M1 macrophage association gene CXCL9 may serve as a good prognostic gene and a potential therapeutic target for cervical cancer therapies.

A retrospective study of Pipelle endometrial biopsy for ovarian, fallopian tube, and peritoneal cancers

Although the Pipelle endometrial biopsy is widely performed as a practical and minimally invasive test for endometrial disease(s), its effectiveness in ovarian cancer has not been explored. The aim of the present study was to evaluate the results of Pipelle endometrial biopsy for ovarian, fallopian tube, and peritoneal cancers. A pre-treatment Pipelle-endometrial biopsy was performed in 90 patients with ovarian, fallopian tube, or peritoneal cancers between January 2014 and November 2021. We retrospectively analysed the association between the results of Pipelle endometrial biopsy and clinicopathological data. Moreover, we evaluated their impact on the following treatment in advanced cases initially treated with chemotherapy. The sensitivity and false-negative rates for Pipelle endometrial biopsy were 25/90 (27.8%) and 65/90 (72.2%) in all patients, respectively, and 23/56 (41.0%) and 33/56 (58.9%) in cases with advanced disease (stages III and IV), respectively. Pipelle-positive endometrial biopsy-positive (Pipelle-positive) was not observed in 29 patients with clinical stage I disease, and Pipelle-positive patients exhibited significantly more high-grade serous carcinomas, and positive peritoneal, endometrial, and cervical cytologies than Pipelle-endometrial biopsy-negative cases. Surgical pathology was confirmed in 23 Pipelle-positive patients, and 17/23 (74.0%) had the same diagnosis as that for Pipelle endometrial biopsy. Conversely, 6/23 (26.0%) patients exhibited a minor diagnostic discrepancy between Pipelle endometrial biopsy and surgical pathology. Nineteen of the 38 (50.0%) patients initially treated with chemotherapy were identified as Pipelle-positive, contributing to a prompt histological diagnosis and pre-treatment tumour sampling. Companion diagnostic tests were performed using Pipelle endometrial biopsy samples from 4 inoperable patients. Although the positive rate of Pipelle endometrial biopsy in ovarian, fallopian tube, and peritoneal cancers is low, Pipelle endometrial biopsy may enable prompt histological diagnosis and initiation of chemotherapy while collecting tumour tissue for genetic testing in some cases with advanced disease.

Causal relationship between affect disorders and endometrial cancer: a Mendelian randomisation study

The aim was to assess the causal relationship between depression and anxiety disorders and endometrial cancer. We performed two-sample Mendelian randomisation analysis using summary statistics from genome-wide association studies to assess associations of major depressive disorder, anxiety and stress-related disorders with endometrial cancer. The genome-wide association studies(GWASs) data were derived from participants of predominantly European ancestry included in the Genome-wide Association Research Collaboration. Inverse variance-weighted, MR-Egger and weighted median MR analyses were performed, together with a range of sensitivity analyses. Mendelian randomisation analysis showed no statistically significant genetic responsibility effect of anxiety and stress-related disorders on any pathological type of endometrial cancer. Only the effect of major depressive disorder under the inverse variance weighting method increasing the risk of endometrial endometrial cancer (effect 0.004 Major depressive disorder(MDD), anxiety and stress-related disorders(ASRD) are not genetically responsible for endometrial cancer. We consider that emotional disorders may affect endometrial cancer indirectly by affecting body mass index. This study provides us with new insights to better understand the aetiology of endometrial cancer and inform prevention strategies.

Retrospective analysis of metabolism-related genes in endometrial carcinoma: links to prognosis and immunity

Endometrial carcinoma is a clinically complex gynaecologic malignancy exhibiting significant molecular heterogeneity. This heterogeneity manifests as marked variability in clinical outcomes and heterogeneous therapeutic responses to emerging treatment modalities, particularly to immune checkpoint inhibitors. Metabolic reprogramming has been implicated in tumour progression and immune evasion in endometrial carcinoma. However, the prognostic implications of metabolism-related genes and their interaction with the tumour immune microenvironment remain insufficiently characterised. RNA-seq and clinical data of endometrial carcinoma were downloaded from The Cancer Genome Atlas (TCGA) database, along with a metabolism-related gene set (MRGs) curated from the Msigdb database. Differential expression analysis was conducted to identify differentially expressed metabolism-related genes (DE-MRGs), which were subsequently analysed to evaluate their expression patterns and prognostic significance in uterine corpus endometrial carcinoma. Functional enrichment was performed via GO and KEGG analysis. The CIBEROSRT computational algorithm was employed to quantify immune infiltration characteristics and their correlation with MRGs. Furthermore, an external GEO dataset (GSE17025) was employed to validate hub gene expression. A total of 49 differentially expressed MRGs were identified in endometrial carcinoma. Functional analyses showed enrichment in retinol and tyrosine metabolism pathways. Two hub genes, LIPG and DDC, were significantly associated with overall survival ( Our study analysed the expression and prognostic relevance of MRGs of endometrial carcinoma. We validated the prognostic value of MRGs and their potential to offer novel insights into prognostication and personalised treatment strategies for endometrial carcinoma.

Asymptomatic endometrial thickening in postmenopausal women: predictor of malignant pathology?

It is not standardised what is the endometrial thickness that discriminates between normal and potentially malignant. The objective of this study was to determine the endometrial thickness cut-off point from which the risk of endometrial cancer (EC) increases in asymptomatic postmenopausal women; and to evaluate the risk factors linked to malignant endometrial pathology as well as other associated ultrasound findings.This was a retrospective observational study that included hysteroscopies performed at the Hospital Materno-Infantil on 267 asymptomatic menopausal women with an increase in endometrial thickness (AET) >5 mm, from 2015 to 2019. The results shows that the prevalence of malignant pathology in asymptomatic postmenopausal women with a casual finding of endometrial thickening was 3.7%. This percentage was 16.3% when the cut-off point of AET was established at 10 mm. There was a significant association for the diagnosis of malignant pathology with this cut-off point.There is a significant association between the 10 mm endometrial thickness cut-off point from which the risk of EC increases in asymptomatic postmenopausal women.Impact statement

The oncological and reproductive outcomes of fertility-preserving treatments for stage 1 grade 1 endometrial carcinoma: a systematic review and meta-analysis

The number of patients desiring fertility-preserving treatment for endometrial cancer rather than standard surgical management continues to increase. We aimed to evaluate the efficacies of fertility-preserving treatments on the live birth rate, remission and relapse rates for women with stage 1a grade 1 endometrial carcinoma to support patient counselling. We performed a meta-analysis for our primary outcomes of overall remission and relapse rate, and for secondary analysis, we divided papers into treatment type: systemic progestins, intrauterine progestins or hysteroscopic resection and adjuvant hormonal treatment. Thirty-five observational studies met inclusion criteria, with a total of 624 patients. Overall, conservative treatment of endometrial cancer showed a remission rate of 77% (95% CI: 70-84%), a relapse rate of 20% (95% CI: 13-27%) and a live birth rate of 20% (95% CI: 15-25%) with more favourable outcomes for the hysteroscopic resection group. Hysteroscopic resection and adjuvant hormonal treatment had the most favourable fertility and oncological outcomes. Further high-quality prospective multi-centre trials are warranted to determine the optimal treatment regimen and dosage and risk stratification for these patients.

The investigation of T-cell receptor subtypes in ovarian cancer: effects on survival and prognostic factors

The aim of this study was to investigate T-cell receptor (TCR) changes in ovarian carcinoma (OC). The study included 24 malignant and 23 benign adnexal masses. DNA was isolated from ovarian samples. Multiplex PCR was used to determine T-cell gene clonality. PCR products were loaded onto polyacrylamide gel electrophoresis and imaged. The relationship between prognostic parameters and T-cell rearrangement was evaluated. In the study group (SG), TCRB-B positivity was higher than control group (CG) and TCRD receptor positivity was higher in CG. In SG, TCRG-B levels were higher in patients with stage I-II tumours compared to stage III. TCRG-B receptor was higher in patients with overall survival of 36 months and above. In our study, subgroups of TCRs were analysed in OC. According to our findings, significant differences in TCRB-B and TCRD subgroups may be applied to immune therapies. Understanding of TCR pathways will provide new treatment approaches in OC.IMPACT STATEMENT

Tumour markers and histopathologic features of ovarian endometriotic cysts

Endometriosis is one of the most common benign gynaecologic diseases and its clinical presentation is generally ovarian endometrioma. We aimed to assess the association of tumour markers with histopathological structure of ovarian endometriomas to assess their roles in clinical management. Data from 86 women who underwent laparoscopic surgery for ovarian endometrioma were evaluated. The possible risk factors for inadvertently removed normal ovarian parenchyma (IRNOP) during laparoscopic cystectomy and the relationship between tumour markers and histopathologic parameters of ovarian endometrioma were assessed. Age and the depth of penetration of endometrial tissue into the cyst wall showed a significant positive correlation with thickness of IRNOP. There was a significant negative correlation between IRNOP and the thickness of fibrosis on cyst wall. Thickness of fibrosis and the depth of penetration represented significant positive correlations with tumour markers (CA 125, CA 15-3, and CA 19-9), respectively. This is the first study that reveals the association between tumour markers and the histopathologic features of ovarian endometrioma. The outcome of the present study indicated that lower levels of tumour markers may permit a conservative management, rising levels may help in timing of a possible surgical intervention and high levels may help in counselling postoperative outcomes.Impact statement

Neoadjuvant chemotherapy in patients with stage IVB uterine serous carcinoma: a Turkish multicentric study

The aim of this study was to evaluate the prognostic factors for and determine the effect of neoadjuvant chemotherapy (NACT) on oncologic outcome in stage IVB pure serous endometrial carcinoma patients who received taxane and platinum. Forty-two patients with 2009 International Federation of Gynecology and Obstetrics (FIGO) stage IVB uterine serous carcinoma were enrolled from six gynecologic oncology centers and a study group was created. The study group had a 2-year disease-free survival (DFS) of 32% and 2-year disease-specific survival (DSS) of 73%. On univariate analysis; lymphadenectomy (not performed vs. performed), paraaortic lymph node metastasis (positive vs. negative) and number of metastatic lymph node count (≤5 vs. >5) were found to have statistical significance for DFS (

Elevated aspartate aminotransferase and alanine aminotransferase in the torsion of ovarian mature cystic teratoma: normalised after operation for torsion

The aim of the study was to report the elevated liver function test levels in torsion of ovarian mature cystic teratoma (MCT). A retrospective review was performed of 116 patients with MCT who underwent surgery in our hospital between 2010 and 2017. Eleven of 116 patients were with torsion of MCT. Of the 11 torsion of MCT cases, 6 of those showed abnormal elevated levels of aspartate transaminase (AST)/alanine aminotransferase (ALT). After operation, AST/ALT levels recovered to normal ranges. Elevated liver function levels require attention to complications associated with anaesthesia and emergency operation. However, the current report shows that emergency surgery should not be delayed to assess other causes of elevated liver function tests.Impact statement

Ovarian cysts in pregnancy: a narrative review

Most adnexal masses are benign, incidental findings of pregnancy which resolve spontaneously. They may present clinically due to haemorrhage, rupture, torsion and mass effect. Aetiological classification includes ovarian benign, ovarian malignant, non-ovarian, gynaecological, non-ovarian non-gynaecological and an additional subset of pathologies unique to pregnancy. Ultrasound is the first-line imaging modality for the evaluation of adnexal masses. This may be supplemented with magnetic resonance imaging. Tumour markers support evaluation of malignant potential, but interpretation of results in pregnancy is challenging. Surgical intervention requires consideration of gestation, lesion characteristics and presence of complications. Laparoscopy is preferred owing to shorter operative time, quicker recovery and resultant lower thrombotic risk. Post-viability, fetal wellbeing and assessment must be considered. Management of the pregnancy may include cardiotocography, steroids, non-teratogenic antibiotics and tocolytics. In rare cases, particularly related to malignancy, termination of pregnancy may be required to enable immediate management where there are concerns for maternal wellbeing.

Adnexal incidentalomas on multidetector CT: how to manage and characterise

Although CT is not considered the examination of choice for the detection and characterisation of adnexal diseases, adnexal masses may be incidentally detected during CT examination performed for other clinical indications. Most adnexal incidentalomas are benign, and therefore may not require further investigation, follow-up or intervention; however, few of them may prove malignant. Multidetector CT has improved the diagnostic performance of the technique in the detection and differentiation of adnexal mass lesions. Radiologists should be able to recognise the normal CT appearance of the ovaries and the CT characteristics of various adnexal incidentalomas. This may obviate unnecessary imaging evaluation and allow optimal treatment planning. Regarding the management of adnexal lesions incidentally found on CT, recommendations based on the collective experience of the members of the American College of Radiology Incidental Findings Committee II have recently been presented.

Cytokines in peritoneal fluid of ovarian neoplasms

The aim of this study was to evaluate cytokine levels (IL-2, IL-8, TNF-α, IL-5, IL-6 and IL-10) in the peritoneal fluid in non-neoplastic tumours, benign ovarian neoplasms and malignant ovarian neoplasms. Peritoneal fluid or ascites was collected from 117 patients with neoplastic and non-neoplastic ovarian tumours. Cytokine levels were assessed by ELISA. The unpaired groups were compared by the Kruskal-Wallis test with Dunn's post-test. Higher IL-6 levels were found in malignant neoplasms when compared to non-neoplastic tumours (

Factors that affect survival in vaginal cancer: a seer analysis

This study aimed to investigate the factors that affect survival in vaginal cancer by means of a large population-based database that had been monitored over a 42 year period (1975-2017). It was investigated which factors were most predictive in survival. This study evaluated the factors that affect survival in primary vaginal cancer as one of the rarest gynaecological cancers. Relationships were explored between survival and age and race of patient, in situ/invasive behaviour of tumour, histological type, stage, grade, surgical treatment, and year of diagnosis. Survival rate was found to be higher at younger ages and earlier stages, in

Diagnostic value of non-coding RNAs in ovarian cancer

The type of primary tumour of the ovary ranks first among all organs in the body. Although the incidence of malignant ovarian tumour ranks third among gynaecological malignancies, it is the most fatal type. A lack of effective diagnostic methods for early ovarian cancer remains, and the efficacy of advanced ovarian cancer is often unsatisfactory; the five-year survival rate of stage III-IV is less than 30%. Non-coding RNA is RNA that does not have protein-coding potential and was once considered as 'junk DNA'. However, increasing number of studies have shown that the disorder of non-coding RNA is related to a variety of diseases, including the occurrence and development of tumours. We summarised the dysregulated non-coding RNAs (miRNAs, circRNAs, and lncRNAs) reported currently in ovarian cancer and their functional mechanisms, and the clinical value of different types of ncRNAs as diagnostic or predictive markers for ovarian cancer, providing further evidence for non-coding RNAs to be considered as biomarkers of ovarian cancer.

Assessment of cervical volume and spectral Doppler parameters in tumour dominant vessel of patients with locally advanced squamous cell cervical carcinoma

We evaluated cervical volume and spectral Doppler parameters: peak systolic velocity (PSV), resistance index (RI) and pulsatility index (PI) in the tumour dominant vessel of 50 patients with cervical squamous cell carcinoma (SCC) staged IIB and IIIB and their changes during treatment. The patients underwent transvaginal Doppler ultrasonography prior to treatment, after external beam radiation therapy (EBRT) and 6 weeks after brachytherapy. Radiotherapy decreased cervical volume and PSV values of the tumour dominant vessel. The PSV values before EBRT in G1 + G2 tumours were higher than in G3 tumours. No correlations between cervical volume, PSV, RI and PI values with disease-free survival (DFS) and overall survival (OS) were found. We concluded, that sonographic assessment of changes in cervical volume of patients with locally advanced cervical SCC during treatment did not allow to predict treatment results. Spectral Doppler parameters PSV, RI and PI of tumour dominant vessel did not predict prognosis for these patients.Impact Statement

Clinical indications referrals – what is the risk of premalignant and malignant female genital tract disease in women referred to a dedicated nurse-led colposcopy service? A retrospective cohort study

Post-coital bleeding (PCB) is a poor predictive factor for cancer and should not be managed as urgent referral. Urgent referral to colposcopy is justified however, in the presence of a visible suspicion of cervical cancer. This retrospective cohort study of women attending a clinical indications referral service aims to identify the risk of pre-malignant and malignant disease in women with clinical indication referrals to colposcopy. Thirty-seven of 3521 women (1%) were diagnosed with pre-malignant cervical or endometrial disease; 14 women (0.4%) were diagnosed with cancer (11 cervix, three endometrial). To detect one cancer in women referred with an abnormal cervix, one would need to see 70 women; to detect one cancer in women referred with PCB one would need to see 790 women. Improved education in primary care and obstetrics and gynaecology training is key to improving clinical indications referral services, which is otherwise an effective and efficient service.Impact Statement

CircRNA circ_0005273 contributes to the cisplatin resistance of cervical cancer cells by sponging miR-133b

Circular RNAs (circRNAs) have been found to play important roles in drug resistance of human neoplasms. The aim of this study was to explore the effect of circ_0005273 on cisplatin (DDP) resistance of cervical cancer (CC) cells and identify its underlying mechanism. The quantitative real-time polymerase chain reaction (qRT-PCR) was performed to analyse circ_0005273 and miR-133b expressions, and cell counting kit-8 (CCK-8), Hoechst 33258 staining and caspase-3 activity analysis were performed to evaluate cell proliferation and apoptosis. Luciferase reporter, RNA binding protein immunoprecipitation (RIP) and RNA pull down assays were applied to explore the interaction between circ_0005273 and miR-133b. Our research showed that circ_0005273 and miR-133b expressions were upregulated and downregulated in DDP-resistant CC cancer tissues and cell lines, respectively. Both of circ_0005273 and miR-133b levels were correlated with FIGO stage, DDP status and overall survival rates. Knockdown of circ_0005273 enhanced the sensitivity of DDP-resistant CC cells to DDP by inhibiting cell proliferation and promoting cell apoptosis. Furthermore, circ_0005273 acts as a competing endogenous RNA to modulate miR-133b expression. Downregulation of miR-133b partly reversed the DDP sensitivity of circ_0005273 knockdown in DDP-resistant CC cells. In summary, our study elucidated the role of circ_0005273/miR-133b axis in DDP resistance of CC cells, which might be a potential therapeutic target for DDP-resistant CC patients. Impact Statement

Outcomes of transvaginal natural orifice transluminal endoscopic hysterectomy: a multi-centre retrospective study from Turkey (TR-MIGS)

Vaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy is gaining increasing popularity among gynaecological surgeons worldwide due to its minimally invasive nature and associated benefits. However, despite its growing adoption, it remains a relatively novel surgical technique that continues to be evaluated and refined in clinical practice. The primary objective of this study is to share and analyse our initial experiences with the implementation of vNOTES hysterectomy across six specialised gynaecological centres in Turkey. This retrospective analysis included all women who underwent vNOTES hysterectomy, with or without salpingo-oophorectomy, for benign or malignant conditions. All procedures adhered to the standardised protocol described by Baekelandt A total of 685 patients underwent vNOTES procedures. Among them, 64 women (9.3%) had a history of one caesarean delivery, 38 (5.5%) had two prior caesareans, and 11 (1.6%) had three or more. Myoma, with or without accompanying metrorrhagia, was the most common surgical indication (53.0%). The mean operative time was 72.4 ± 40.2 min, and the average haemoglobin decrease was 1.3 ± 1.0 g/dL. The mean uterine weight was 204 ± 145 g. Intraoperative complications occurred in 1.7% of cases ( These findings support vNOTES as a safe and effective surgical approach, offering a viable alternative to traditional laparoscopic or vaginal techniques in select patient populations.

6-Phosphofructo-2-kinase/fructose-2,6-biphosphatase 4 (PFKFB4) was reported to be necessary for tumour growth in several cancers. However, the function of PFKFB4 in cervical cancer has not been clearly elucidated. Bioinformatics analysis was applied to detect the expression of PFKFB4 in cervical cancer and the association with survival prognosis. The effect of PFKFB4 on cervical cancer cells growth, cycle, invasion, migration and glucose metabolism was investigated by loss-of-function approaches

The impact of serum albumin-to-alkaline phosphatase ratio in cervical cancer patients treated with definitive chemoradiotherapy

We retrospectively analysed the prognostic significance of serum albumin, alkaline phosphatase (ALP) and albumin to ALP ratio (AAPR) and other prognostic factors affecting the overall survival (OS) and progression-free survival (PFS) in 200 cervical cancer patients treated with definitive chemoradiotherapy (CRT). The prognostic factors for OS and DFS, in addition to the predictive factors of albumin, ALP and AAPR, were investigated. Older age, lymph node metastasis, non-complete response (CR) to treatment and low serum albumin levels emerged as predictors of poor OS and PFS in multivariate analysis. However, with a cut-off value of 0.51, AAPR was not a significant prognostic factor of survival in multivariable analysis. There were no significant differences in clinicopathological factors between patients with low and high AAPR, except for lymph node metastasis, where lymph node metastasis rate was significantly higher in patients with a low AAPR compared to those with a high AAPR. Patients with CR had a significantly higher serum albumin level and AAPR compared to patients without CR. The pre-treatment serum albumin level was independent predictive for survival; therefore, it could be a suitable biomarker to guide systemic therapy and predict patient outcomes. Impact Statement

The effect of consolidation chemotherapy after concurrent chemoradiation on the prognosis of locally advanced cervical cancer: a systematic review and meta-analysis

To verify the role of consolidation chemotherapy after concurrent chemoradiotherapy for bulky and locally advanced cervical cancer, a meta-analysis was performed. Based on articles published up to Jun 2020 a literature search in PubMed, EMBASE and Cochrane Library was conducted to identify eligible studies. A total of 4 articles consisting of 1659 patients were enrolled. The pooled results revealed that overall survival (OS) of patients treated with consolidation chemotherapy after concurrent chemoradiotherapy (CCRT + CT) was significantly superior to concurrent chemoradiotherapy (CCRT) alone (HR = 0.78, 95% CI: 0.69-0.88,

CST2 promotes cell proliferation and regulates cell cycle by activating Wnt-β-catenin signalling pathway in serous ovarian cancer

Cystatin SA (CST2) plays multiple roles in different types of malignant tumours; however, its role in serous ovarian cancer (SOC) remains unclear. Therefore, we aimed to investigate the expression levels, survival outcomes, immune cell infiltration, proliferation, cell cycle, and underlying molecular mechanisms associated with the CST2 signature in SOC. The Cancer Genome Atlas database was used to acquire clinical information and CST2 expression profiles from patients with SOC. Wilcoxon rank-sum tests were used to compare CST2 expression levels between SOC and normal ovarian tissues. A prognostic assessment of CST2 was conducted using Cox regression analysis and the Kaplan-Meier method. Differentially expressed genes were identified using functional enrichment analysis. Immune cell infiltration was examined using a single-sample gene set enrichment analysis. Cell cycle characteristics and proliferation were assessed using a colony formation assay, flow cytometry, and a cell counting kit-8 assay. Western blots and quantitative reverse transcription PCR analyses were employed to examine CST2 expressions and related genes involved in the cell cycle and the Wnt-β-catenin signalling pathway. Our findings revealed significant upregulation of CST2 in SOC, and elevated CST2 expression was correlated with advanced clinicopathological characteristics and unfavourable prognoses. Pathway enrichment analysis highlighted the association between the cell cycle and the Wnt signalling pathway. Moreover, increased CST2 levels were positively correlated with immune cell infiltration. Functionally, CST2 played vital roles in promoting cell proliferation, orchestrating the G1-to-S phase transition, and driving malignant SOC progression through activating the Wnt-β-catenin signalling pathway. The elevated expression of CST2 may be related to the occurrence and progression of SOC by activating the Wnt-β-catenin pathway. Additionally, our findings suggest that CST2 is a promising novel biomarker with potential applications in therapeutic, prognostic, and diagnostic strategies for SOC.

Outcomes of minimal access retroperitoneal para-aortic lymphadenectomy in patients with locally advanced cervical cancer

To evaluate outcomes of laparoscopic retroperitoneal para-aortic lymphadenectomy for stage 1b3-3b cervical cancer. Pathology databases searched for all para-aortic lymphadenectomy cases 2005-2016. Descriptive statistics were used to analyse baseline characteristics, cox models for treatment affect after accounting for variables, and Kaplan Meier curves for survival (STATA v15). 191 patients had 1b3-3b cervical cancer of which 110 patients had Para-aortic lymphadenectomy. 8 (7.3%) patients stage 1b3, 82 (74.6%) stage 2b, and 20 (18.1%) stage 3b cervical cancer. Mean lymph node count 11.7 (SD7.6). The intra-operative and post-operative 30 day complication rates were 8.8% (CI: 4.3%, 15.7%) and 5.3% (CI: 1.9%, 11.2%) respectively.Para-aortic nodes were apparently positive on CT/MRI in 5/110 (5%) cases. Cancer was found in 10 (8.9%, CI: 4.3%, 15.7%) cases on histology, all received extended field radiotherapy. Only 2 were identified on pre-operative CT/MRI imaging. 3 of 10 suspected node-positive cases on CT/MRI had negative histology. Para-aortic lymphadenectomy led to alteration in staging and radiotherapy management in 8 (8%, CI: 3.7%, 14.6%) patients. Mean overall survival 42.81 months (SD = 31.79 months). Survival was significantly higher for women undergoing PAN (50.57 (SD 30.7) months) compared to those who didn't (31.27 (SD 32.5) months). Laparoscopic retroperitoneal para-aortic lymphadenectomy is an acceptable procedure which can guide treatment in women with locally advanced cervical cancer.

Evaluation of the optimal laparoscopic method for benign ovarian mass extraction: a transumbilical route using a bag made from a surgical glove versus a lateral transabdominal route employing a standard endobag

We compared two transumbilical (TU) routes of surgical specimen retrieval in women with ovarian masses treated via laparoscopy: a bag made from a surgical glove and lateral transabdominal (LTA) retrieval employing a standard endobag. A total of 109 women undergoing laparoscopic surgery to treat benign adnexal masses were retrospectively evaluated between 2014 and 2017. In total, 57 masses were removed via the TU route and 52 via the LTA route. We recorded the ovarian mass size; additional postoperative analgesic drug requirements. Postoperative incisional pain scores were assessed using a 10-cm visual analogue scale (VAS), time to discharge and procedure type. The mean VAS scores at 1 h (5.0 ± 1.7 vs. 6.3 ± 1.3;

Preoperative plasma D-dimer level is a useful prognostic marker in ovarian cancer

A high pre-treatment plasma D-dimer level was recently identified as a poor prognostic factor in several malignancies. The aim of this study was to evaluate the prognostic significance of plasma D-dimer levels in epithelial ovarian cancer (EOC). Data of 199 patients were retrospectively analysed. The relationships between pre-treatment D-dimer levels and other clinical parameters and prognosis were evaluated. Univariate analysis identified age, pre-treatment plasma D-dimer level, massive ascites, residual tumours, pre-treatment CA125 level, histological type, and FIGO stage as predictors of overall survival. The multivariate analysis showed that a high pre-treatment plasma D-dimer level (

Effect of cancer stage on health-related quality of life of patients with epithelial ovarian cancer

We compared the quality of life (QoL) of women with early versus advanced epithelial ovarian cancer and examined predicting factors for the poor QoL. We classified 157 participants into 108 with early disease (stage I-II) and 49 with advanced disease (stage III-IV). They completed two questionnaires: EORTC QLQ-C30 and Chiang Mai University (CMU) ovarian cancer QoL. For EORTC QLQ-C30, the study groups were comparable regarding global health status/QoL, functional scales, and summary scores. The advanced group had worse scores on symptom scales specifically appetite loss and constipation. For CMU Ovarian Cancer QoL, the advanced group had worse scores only in the gastrointestinal domain but not in urinary, lymphatic, and sexual/hormonal domains. These findings remained mostly unchanged after excluding those with recurrence. In multivariable analysis, currently receiving treatment was consistently associated with worse QoL scores. The advanced stage had more adverse impact only on the gastrointestinal domains of QoL, mainly during periods of receiving chemotherapy.IMPACT STATEMENT

Poor anaerobic threshold and VO2 max recorded during cardiopulmonary exercise testing (CPET) prior to cytoreductive surgery in advanced (stage 3/4) ovarian cancer (AOC) is associated with suboptimal cytoreduction but does not preclude maximum effort cytoreduction

This study assessed Cardiopulmonary Exercise Testing (CPET) in predicting oncological outcomes, post-operative recovery and complications in advanced ovarian cancer (AOC) cytoreductive surgery. We reviewed all patients who had CPET prior to AOC cytoreductive surgery with evidence of upper abdominal disease on preoperative imaging at the University Hospitals of Derby and Burton (UHDB) between August 2016 and July 2019. Patients were stratified by AT and maximum VO

The oncogenic roles of GPR176 in ovarian cancer: a molecular target for aggressiveness and gene therapy

At present, the discovery of new biomarkers is of great significance for the early diagnosis, treatment and prognosis assessment of ovarian cancer. Previous findings indicated that aberrant G-protein-coupled receptor 176 (GPR176) expression might contribute to tumorigenesis and subsequent progression. However, the expression of GPR176 and the molecular mechanisms in ovarian cancer had not been investigated. GPR176 expression was compared with clinicopathological features of ovarian cancer using immunohistochemical and bioinformatics analyses. GPR176-related genes and pathways were analysed using bioinformatics analysis. Additionally, the effects of GPR176 on ovarian cancer cell phenotypes were investigated. GPR176 expression positively correlated with elder age, clinicopathological staging, tumour residual status, and unfavourable survival of ovarian cancer, but negatively with purity loss, infiltration of B cells, and CD8+ T cells. Gene Set Enrichment Analysis showed that differential expression of GPR176 was involved in focal adhesion, ECM-receptor interaction, cell adhesion molecules and so on. STRING and Cytoscape were used to determine the top 10 nodes. Kyoto Encyclopaedia of Genes and Genomes analysis indicated that GPR176-related genes were involved in the ECM structural constituent and organisation and so on. GPR176 overexpression promoted the proliferation, anti-apoptosis, anti-pyroptosis, migration and invasion of ovarian cancer cells with overexpression of N-cadherin, Zeb1, Snail, Twist1, and under-expression of gasdermin D, caspase 1, and E-cadherin. GPR176 might be involved in the progression of ovarian cancer. It might be used as a biomarker to indicate the aggressive behaviour and poor prognosis of ovarian cancer and a target of genetic therapy.

Long-term risks of coronary heart disease and cerebrovascular disease in ovarian, uterine and cervical cancer survivors: a nationwide study in Korea

Only few studies have evaluated the incidence of coronary heart disease (CHD) and cerebrovascular disease (CVD) among gynaecologic cancer survivors. We selected 26,880 gynaecologic cancer patients who underwent health check-ups within 2 years after diagnosis using the Korean National Health Insurance Service Database. They were compared with 79,830 non-cancer controls. Cox regression models were used to estimate hazard ratios (HRs). There was no significant relationship between gynaecologic cancer survivors and CHD or CVD events. However, 10 years after diagnosing cancers, the risk of angina increased in cancer survivors (adjusted HR = 1.193, 95% CI: 1.013-1.406). After 1 year of diagnosis, cancer patients with no initial comorbidities showed an increased risk of all CHD and CVD events (adjusted HR = 1.101, 95% CI: 1.020-1.189) and CHD alone (adjusted HR = 1.168, 95% CI: 1.055-1.293) compared with controls. CHD risk was also higher in the cancer group with no comorbidities after 10 years of diagnosis (adjusted HR = 1.284, 95% CI: 1.020-1.615). Overall, the risk of CHD or CVD did not increase in gynaecologic cancer survivors. However, cancer patients without any comorbidities showed a higher risk of CHD compared with control, the risk persisting until 10 years after cancer diagnosis.Impact Statement

Borderline ovarian tumors: a retrospective cohort study on single institution experience, practice patterns and outcomes

Borderline ovarian tumours (BOTs) commonly affect young nulliparous women, thus making fertility-preserving approaches more desirable. Women who opt for conservative management should be counselled about disease recurrence. In this retrospective study, the medical records of 57 women with BOT treated at the American University of Beirut Medical Centre between January 1986 and May 2018 were reviewed. Clinical, pathologic, and demographic data were collected and analysed to identify variables associated with poor clinical outcomes including advanced disease and risk of recurrence. Younger and nulliparous women were more likely to undergo fertility-sparing surgery. The open approach was adopted for women with larger adnexal masses and was associated with more blood loss with a mean difference of 172 mL (95% CI [110-235],

Quantification and influencing factors of perioperative hidden blood loss in patients undergoing laparoscopic ovarian cystectomy for benign ovarian tumours

This retrospective, monocentric study quantified hidden blood loss (HBL) and investigated its influencing factors in benign ovarian tumour patients undergoing laparoscopic ovarian cystectomy. Data from 153 patients who underwent laparoscopic ovarian cystectomy were retrospectively reviewed. HBL was calculated using the formula derived from 'Nadler' and 'Cross'. Pearson correlation was carried out to measure the association between HBL and potential risk factors. The average HBL was 280.22 ± 168.42 mL, accounting for 84.13 ± 19.20% of total blood loss (TBL) (347.48 ± 179.05 mL), which was a change of almost fourteen-fold relative to median visible blood loss [20.00 mL (10.00 mL, 57.5 mL)]. Surgical time, number of excisional tumours and preoperative albumin values were risk factors for HBL. HBL represents a large proportion more than 80% of TBL in patients undergoing laparoscopic ovarian cystectomy. Collectively, HBL is helpful for estimating intraoperative blood loss and better guidance of haemostatic agents, which reduces postoperative complications and expedites postoperative recovery. Additionally, the estimation of HBL also contributes to the summary, reflection and improvement of surgical technique.IMPACT STATEMENT

Prevalence of ovarian mass and diagnostic performance of ultrasonography pattern recognition among women at the Gynaecologic Ultrasonography Unit at University Hospital in Thailand

The aim of this retrospective study was to determine the prevalence of ovarian masses and calculate the diagnostic performance of the pattern recognition approach in ovarian pathology. A total of 1001 patients diagnosed with ovarian mass were included, of which 92.6% were diagnosed with ovarian pathology and the presence of a pathological result, while 7.4% of cases were diagnosed with functional ovarian cyst. The prevalence of ovarian malignancy was 15%. A specific ultrasound diagnosis was suggested in 62.9% of all cases, while sonographers did not explicitly provide a diagnosis in remaining cases. A subjective assessment showed 80.3% sensitivity (95% confidence interval (CI) 68.7-89.1) and 97.6% specificity (95% CI 96-98.6) in differentiating between benign and malignant ovarian masses. The sensitivity and specificity for the diagnosis of endometriotic cyst were 77.03% and 90.63% and 63.19% and 94.3% for mature cystic teratoma, respectively. In conclusion, assessment showed good performance in differentiating between benign and malignant ovarian mass and it was possible to diagnose several specific ovarian tumours. Impact Statement

Survival in recurrent ovarian cancer patients before and after the bevacizumab era: an observational single-centre study

Human papillomavirus: present and future perspective in Saudi Arabia

Human papillomavirus (HPV) is a widely dispersed DNA double-stranded carcinogenic virus worldwide. Many cancers have been attributed to HPV subtypes as a major aetiological factor. Around 90% of cervical cancers have been attributed to the HPV infection, in addition to other cancers such as head and neck cancer, breast cancer and other cancers. As the carcinogenic high risk and low-risk, HPV subtypes are sexually transmitted viruses, and the Saudi community is religiously conservative, lots of measures of the precise burden of the HPV and its related cancers are still obscure. With the absence of cervical-screening programmes and in-depth research in HPV-related cancers, there a lack of literature except for literature pertained to awareness and perceptions. Consequently, the present review is deemed to explore the present state of the HPV-related issues, the future perspective in light of the current scientific evidence, as well as, Saudi community practices, and health policies in this regard. Making accessible data on HPV-related cancers can assist in designing HPV-related early detection and control sustainable programmes. Therefore, this review aimed to discuss the most important magnitudes related to the HPV, concerning the available literature from Saudi Arabia and the data in the neighbouring Arab countries interrelated to Saudi Arabia. The review depended on searching Electronic databases using strongly considered indexes including PubMed, Medline, Web of Science, Scopus, ABSCO, EMBASE, and others. In conclusion, though Saudi Arabia is pronounced as a conservative community with low sexual transmitted diseases, there is an alarming menace of HPV-attributable diseases necessitating a quick intervention.

A 5-gene DNA methylation signature is a promising prognostic biomarker for early-stage cervical cancer

The demographic information and overall survival (OS) of patients with cervical cancer (CC) (pathological stage: IA-IIA) were extracted from the TCGA database. A univariate and multivariate Cox proportional hazard model was performed to identify methylation markers significantly associated with the OS of patients in the training dataset. Then such a prognostic classifier was tested on the validation set and all subgroups. The Kaplan-Meier analysis and ROC analysis were performed to detect the ability to discriminate between patients with different risks and different OS. A DNA methylation signature which contained five genes was found to be significantly associated with the OS of CC patients by the Cox regression analysis in the training dataset. Such a signature could efficiently distinguish the patients into two risk groups with significantly different OS in both datasets. The receiver operating characteristic (ROC) analysis showed it had high sensitivity and specificity. Moreover, such a prognostic model also could be effectively applied to different subgroups, including groups of different ages, tumour sizes, histologic types, etc. A 5-DNA methylation signature identified by this study may act as a novel prognostic indicator for early-stage CC, and it may be helpful for the timely diagnosis and intervention of CC at pathological stages IA-IIA.Impact Statement

Breast and cervical cancer screening for risk assessment in Cambodian women

The estimated mortality rates for breast and cervical cancer in Cambodia are high, perhaps because the Cambodian population lacks information about their detection and prevention. This cross-sectional study assessed the distribution of cervical cancers among and the behavioural and clinical characteristics of Cambodian women. It comprised 1039 Cambodian women who were interviewed between August 2013 and January 2016; the interviews were conducted in person using structured questionnaires. Among the participants, 801 (77.2%) and 709 (68.3%) had heard of cervical cancer and cervical cancer detection tests, respectively. However, 830 (80.2%) had never undergone a Pap smear, and 633 (60.9%) had never heard of breast self-examination. Despite the high mortality rates for breast and cervical cancer in Cambodia, only a small percentage of the participants had risk factors (e.g. smoking, alcohol consumption) for female cancers. A nationwide survey of the knowledge, attitudes and practices related to female cancers is recommended.Impact Statement

Pulmonary recurrence after radical hysterectomy for uterine cervical carcinoma

Pulmonary spread from carcinoma of the uterine cervix, though uncommon, has been reported in 2.2-9.1% of all cervical cancers. The aim of this study was to evaluate the surgical, clinical, pathological factors and clinical outcomes of cervical cancer patients with pulmonary recurrence (PR).This study included 17 cervical cancer patients with PR after radical hysterectomy. The entire cohort consisted of 413 patients whose surgeries (type III radical hysterectomy + pelvic ± para-aortic lymphadenectomy) had been performed in our Gynaecologic Oncology Clinic between 1993 and 2018. Tumour size, lymph node metastasis and receiving adjuvant therapy were found to be effective for PR on univariate analyses in the main cohort (

Role of ganglioside biosynthesis genetic polymorphism in cervical cancer development

Cervical cancer is the most common gynaecological cancer in women. Cell mediated immunity plays a significant role in the progression or regression of neoplastic cervical lesions caused by human papilloma virus infection. Engagement of antigen-specific T cell receptors is a prerequisite for T cell activation. The initial events of T cell activation involve the movement of the T cell receptor into specialised microdomains known as lipid rafts. Gangliosides play an active role in the formation, stabilisation and biological functions of lipid rafts. This study aims to determine whether polymorphisms in the genes involved in the biosynthesis of gangliosides represent risk a factor for cervical cancer.Taqman methods for single nucleotide polymorphism genotyping was used. All subjects carried the homozygous wild-type genotypes for all analysed genes (CC for gene

Postoperative nomogram for the prediction of disease-free survival in lymph node-negative stage I–IIA cervical cancer patients treated with radical hysterectomy

The purpose of this study was to develop and validate a nomogram for individual prediction of recurrence and disease-free survival (DFS) among lymph node (LN)-negative early-stage (I-IIA) cervical cancer (CC) patients treated with Type B or Type C2 hysterectomy. Data were collected from patients diagnosed with CC between 1995 and 2017 at the Gynecological Oncology Department, Tepecik Training and Research Hospital. A total of 194 cases with stage IA2-IIA CC were evaluated retrospectively. Patients with stage IA2-IIA CC who underwent radical (Type C2) or modified radical (Type B) hysterectomy and pelvic ± paraaortic LN dissection with LN negativity were included in the study. The relationships between prognostic factors such as stage, tumour size, parametrial involvement, vaginal cuff margin, endomyometrial infiltration, and lymphovascular space invasion status and DFS were compared using a univariable Cox regression model. When the nomogram was prepared, the scores of the risk factors were collected, and we observed that scores were at least 0 to a maximum of 414 points. The concordance-index for the nomogram was 0.895 (95% confidence interval, 0.79-0.99). The nomogram based on the indicated prognostic factors yielded excellent results in predicting recurrence in early-stage CC patients without LN metastasis who underwent radical hysterectomy.Impact statement

Can we predict surgical margin positivity while performing cervical excisional procedures?

We designed this study to evaluate any factors associated with positive surgical margin in conisation specimens and to determine the optimal cone size. The medical records of patients who had undergone a loop electrosurgical excision procedure (LEEP), cold-knife conisation (CKC) and needle excision of the transformation zone (NETZ) procedure were reviewed retrospectively. Two hundred and sixty eight women fulfilled the inclusion criteria. Univariate analyses showed that 'postmenopause', 'HSIL on smear', 'previous colposcopic examination revealing HSIL in endocervical curettage (ECC) material and in two or more ectocervical quadrants' and 'managing with LEEP' were significant predictors of surgical margin positivity. Nulliparous patients showed significantly lower rate of surgical margin positivity. 'Postmenopause', 'previous colposcopic examination revealing HSIL in ECC material and in two or more ectocervical quadrants' and 'HSIL on smear' were identified as independent predictors of surgical margin positivity according to multivariate analyses.IMPACT STATEMENT

Searching for an ideal cervical cancer screening model to reduce false-negative errors in a country with high prevalence of cervical cancer

The purpose of this study was to develop an ideal cervical cancer screening model to reduce false-negative errors in Korea where there is a high prevalence of cervical cancer. We conducted a cross-sectional study including 33,531 women who underwent routine cervical cancer screening in Korea. Colposcopic examinations were performed after abnormal results on their screening tests. Diagnostic capacities including sensitivity, specificity, and false-negative rate of each screening scenario were analysed at the CIN1 or worse (CIN1+) threshold with colposcopic biopsy results considered the gold standard. A total of 4117 women had valid results for Papanicolaou (Pap) cytology, human papilloma virus (HPV) tests, cervicography, and colposcopically directed biopsy were included in this study. The disease prevalence of CIN1+ was 38.1%. Pap-alone resulted in the highest false-negative rate of 46.9%, followed by HPV-alone at 25.1%, cervicography-alone at 18.7%, Pap/HPV-combined at 15.0%, Pap/cervicography-combined at 6.9% and Pap/HPV/cervicography-combined at 2.9% in a sample of 1570 women with CIN1+ lesions. Therefore, cervicography demonstrated excellent performance for the detection of CIN or cervical cancer and markedly reduced false-negative errors when used in combination with Pap cytology and HPV tests.IMPACT STATEMENT

Prognostic indicators and survival rates in vulvar cancer: insights from a retrospective study

This study aimed to ascertain prognostic indicators impacting progression-free survival (PFS) and overall survival (OS) in patients diagnosed with vulvar cancer. The secondary aim was to determine a quantifiable measure of PFS and OS for these patients. A comprehensive retrospective review was conducted of the medical records of vulvar cancer patients treated at Siriraj Hospital from 2006 to 2020. Patient characteristics, surgical outcomes, pathological features and immunohistochemical results for p16, p53 and PD-L1 were analysed for their potential as prognostic indicators for survival outcomes. In the sample of 104 vulvar cancer patients, four factors were significantly associated with a worsening PFS. They were coexisting vulvar lesions such as lichen sclerosus and extramammary Paget's disease ( Factors leading to unfavourable PFS are coexisting vulvar lesions, positive LVSI status, pelvic or paraaortic lymph node metastases, and positive p53 status. Regarding OS, a tumour diameter exceeding 4 cm significantly correlates with poorer outcomes.

Nicotinamide N-methyltransferase expression in squamous cell carcinoma of the vulva

The molecular pathways involved in the development of vulvar squamous cell carcinoma (SCC) cancer are not completely known. Nicotinamide N-methyltransferase (NNMT) is a cytosolic enzyme associated with tumorigenesis and metastasis in a variety of cancers. Its role in vulvar cancer has not been studied, previously. Vulvar SCC, high and low grade squamous intraepithelial lesions (SILs) and benign squamous hyperplasia were analysed immunohistochemically.

Survival outcomes and prognostic factors of papillary serous adenocarcinoma and papillary squamous cell carcinoma of the uterine cervix

The aim of this retrospective population-based study was to investigate the survival outcomes and prognostic factors of patients with the two cervical carcinomas. A cohort of patients diagnosed with papillary serous adenocarcinoma of the uterine cervix (PSAC) and papillary squamous cell carcinoma (PSCC) between 1973 and 2015 were drawn from the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) database. Overall survival (OS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method, and prognostic factors were assessed using Cox proportional hazards survival regression analysis. The 5-year and 10-year OS rates were 38.4 and 33.1% for PSAC and 64.6 and 50.8% for PSCC, respectively. The 2-year and 5-year CSS rates were 60.6 and 45.9% for PSAC and 79.6 and 69.0% for PSCC, respectively. Patients with PSCC survive longer than PSAC patients and have other well-described prognostic factors for improved survival rates, including an early cancer stage, a younger patient age and standardised surgery.Impact statement

Squamous cell carcinoma antigen combined with HPV-16 infection in predicting high-grade squamous intraepithelial lesions of the cervix

An early screening of HPV and the Thinprep Cytology Test (TCT) can effectively prevent cervical cancer. However, patients with high-grade cervical intraepithelial neoplasia usually escape current screening methods and commonly develop cervical cancer. Hence, to identify effective and specific screening methods for high-grade cervical intraepithelial neoplasia is of vital necessity. In this study, 541 patients collected in Sun Yat-Sen hospital from January 2007 to December 2016 were selected. HPV genotype detection and SCC-ag detection were done in these patients. It was found that when serum SCC-ag level exceeded over 0.39 ng/ml in HPV-16 positive patients, the sensitivity and specificity of this novel approach to predict high-grade cervical intraepithelial neoplasia could reach to 83.1% and 62.1%, respectively. The result suggested that the combination of serum SCC-ag level and HPV-16 infection could be used as a novel approach for high-grade cervical intraepithelial neoplasia screening.Impact statement

Health-related quality of life for early-stage cervical cancer survivors after primary radical surgery followed by radiotherapy versus radical surgery alone

This study compared the quality of life (QoL) of 265 stage IA2-IIA cervical cancer patients treated with radical surgery alone (group 1: 137 patients) versus those who underwent primary radical surgery followed by radiotherapy (group 2: 128 patients) and identified clinical characteristics that predict the poor quality of life. All participants completed quality of life questionnaires: EORTC QLQ-C30 and CMU cervical cancer QoL. For the EORTC QLQ-C30, the study groups were comparable regarding global health status/QoL scale and summary scores. Group 1 participants had better scores on the physical functioning domain and some symptom scales/items. For the CMU Cervical Cancer QoL, group 1 participants had better scores on gastrointestinal, lymphatic, and sexual/hormonal domains. In multivariable analysis, adjuvant radiation was consistently associated with poor quality of life in most domains. In general, early-stage cervical cancer survivors had a satisfactory quality of life. The clinical significance of the quality of life score differences between the study groups remains debateable.Impact statement

The effect of adjuvant radiotherapy on oncological outcomes in patients with early-stage cervical carcinoma with only intermediate-risk factors: a propensity score matching analysis

We aimed to evaluate whether adjuvant radiotherapy had a survival benefit for patients with early-stage cervical carcinoma with intermediate-risk factors. This study included patients who underwent radical hysterectomy and lymphadenectomy according to Wertheim-Okabayashi for stage IB1-IIA2 cervical carcinoma. Each patient had at least one intermediate-risk factor including tumour diameter ≥4 cm, deep stromal invasion, and positive lymphovascular space invasion (LVSI). Patients with lymph node metastasis, parametrial invasion, and positive surgical margins according to the final paraffin section were excluded. In total, 183 patients were included. Seventy-three (39.9%) patients had one, 85 (46.4%) had two, and 25 (13.7%) had three intermediate risk factors. Sixty-seven (36.6%) patients received adjuvant radiotherapy. There was a statistically significant difference in terms of stage, LVSI, and endometrial/uterine invasion between the groups that did and did not receive adjuvant radiotherapy (

Circ_0072995 drives cervical cancer development by regulating the miR-29a/WDR5 axis

Circular RNA_0072995 (Circ_0072995) is involved in the pathogenesis of cancers; however, no study has investigated its role in cervical cancer. Therefore, we aimed to investigate the function of circ_0072995 in cervical cancer. Normal human cervical epithelial cells (hCECs), HeLa cells, and forty female nude BALB/c mice were used. Immunohistochemistry, invasion assays, flow cytometric analysis, luciferase assays, and tumour volume measurements were performed to explore the potential mechanism. Circ_0072995 was significantly up-regulated in cancer tissues, and its level was markedly correlated with the International Federation of Gynecology and Obstetrics system (FIGO) staging.

Knowledge and attitude towards human papillomavirus and its vaccination and affecting factors among nursing and medical students: a questionnaire study

The aim of this study was to investigate the knowledge about the Human Papillomavirus (HPV), HPV testing and HPV vaccinations and affecting factors among nursing and medical students and explore their attitudes regarding HPV vaccination. A cross-sectional study was conducted with 635 undergraduate nursing and medical students from March to June 2020 at a state university in Turkey. The data were collected using the Questionnaire Form and HPV Knowledge Scale (HPV-KS). The HPV-KS mean scores of the students were 17.07 ± 6.95. The students were aged 26 and over, females, had good economic status, registered at the faculty of medicine, at higher year of studies, had sexual experience and recommended HPV vaccination got higher knowledge scores regarding HPV, HPV testing and HPV vaccination (

Is there still a necessity for awareness and information about HPV infection and vaccine for adolescent in developing countries?

Increasing awareness of human papilloma virus (HPV) and vaccines among the target population is an important factor for decreasing the rate of malignancies related to HPV. The aim of this cross-sectional study was to determine Turkish high school and college students' knowledge level of HPV and vaccines via a survey. The HPV knowledge scale (HPV-KS) has been developed to measure the level of knowledge about HPV and vaccination. The response rate of 'Yes' to the question of whether the participants have heard of HPV and the vaccine was 60.8% and 58.8%, respectively. The lack of information was the commonest reason for not being vaccinated in 54% of the participants. According to the HPV-KS, the median value of the knowledge level of the participants was 35.7 (IQR; 14.3-57.1). The HPV-KS scores were significantly higher among those with parents who had graduated from university and had an income above the minimum wage than those who did not (

Long-term quality of life assessment after excisional treatment for cervical dysplasia

We evaluated factors influencing long-term health-related quality of life (HRQoL) after excisional treatments of low- and high grade squamous intraepithelial cervical lesions (SIL) in three groups of women (

Prognostic value of systemic inflammatory response markers in cervical cancer

We investigated the association between preoperative ratios of inflammatory markers and the prognosis in patients with invasive cervical cancer (CC). In this single-centre study, we retrospectively enrolled 163 CC patients who underwent radical hysterectomy between February 2008 and October 2018. Among the evaluated ratios, a high neutrophil-to-lymphocyte ratio (N/L) was significantly associated with deep stromal invasion and tumour size larger than 2 cm, whereas a high M/L was significantly related to advanced-stage CC (IB3-IIIC2), lymphatic metastasis (total) and pelvic lymph node metastasis (

Stereotactic body radiotherapy boost in patients with cervical cancer

Our aim was to evaluate the oncological outcomes of stereotactic body radiotherapy (SBRT) boost in patients with cervical cancer. The data of 21 patients who received SBRT boost after definitive radiotherapy (RT) or chemoradiotherapy (CRT) between March 2012 and April 2019 were retrospectively evaluated. External beam radiotherapy (EBRT) was applied to patients with a total dose of 50.4 Gy in 28 fractions. Kaplan-Meier method was used for survival analysis (IBM SPSS 23 software) and

Comparison of conventional and liquid-based Pap smear methods in the diagnosis of precancerous cervical lesions

Cervical cancer is one of the five most common cancers among women. The present study aimed to compare conventional and liquid-based Pap smear methods in 2018 in Kerman, Iran. This was a cross-sectional study. Pap smear samples (conventional Pap smear (CN) and liquid-based cytology (LBC)) were collected from five health centres in Kerman. Samples were classified into two groups of liquid and CNs, and each group was classified into normal, abnormal (including, atypical squamous cells of undetermined significance (ASCUS

Clinical significance of CD34, podoplanin and Ki-67 expression in patients with locally advanced squamous cell cervical carcinoma

The aim of the study was to assess immunohistochemical CD34, podoplanin and Ki-67 expression in cervical tumour of patients with cervical squamous cell carcinoma (SCC) staged IIB and IIIB, a relationship with selected clinical and histological parameters and its prognostic significance. This prospective study included 52 patients. Microvessel density (MVD) by CD34, lymphatic vessel density (LVD) by podoplanin and the Ki-67 index in specimens from paraffin blocks with cervical SCC tissues were examined. The relationship between these data and selected clinical and histological parameters was analysed. Positive correlation of MVD and the Ki-67 index was observed. No correlation was observed for MVD, LVD and the Ki-67 index in the tumour with staging, grading, length of treatment and squamous cell carcinoma antigen (SCC-Ag) concentration before and after treatment. The expression of MVD, LVD and the Ki-67 index in cervical SCC did not contribute to the risk of relapse and cancer-related death. No relationship was found for MVD, LVD and the Ki-67 index in cervical tumour of patients with locally advanced cervical SCC with staging, grading and serum SCC-Ag level. MVD, LVD and the Ki-67 index in the tumour did not contribute to the risk of relapse or cervical SCC-related death.Impact Statement

The Manchester operation – is it time for it to return to our surgical armamentarium in the twenty-first century?

We conducted a study to assess the efficacy and outcome results of Manchester operation for women with symptomatic elongation of uterine cervix between 2010 and 2020. Forty-five women were enrolled. Mean age was 54.2 ± 10.5 years, 57.5% were premenopausal. Mean follow up was 4.53 years. Most patients were pleased from the surgery: 29 (76.3%) very pleased and three (7.9%) quite pleased. There were four cases of late postoperative complications: hematometra, pyometra, vesicovaginal fistula and small bowel evisceration through the posterior vaginal fornix. All four cases required surgical interventions with complete recovery. Manchester operation is an effective procedure for symptomatic elongation of uterine cervix. The surgery is short, minimal blood loss and without significant intraoperative complications. However, it is not free of late postoperative complications and it is therefore important that the surgery will be carried out with a strict technique and by skilled surgeons who are capable to manage unique postoperative complications.Impact Statement

Outcomes of laparoscopic myomectomy for large and high-order fibroids: a single-centre service evaluation

Ethnic minority patients experience a higher uterine fibroid disease burden and reduced access to minimally invasive myomectomy. Restrictive selection criteria may disproportionately exclude these patients from laparoscopic surgery. This was a prospective service-evaluation database analysed retrospectively, including all conventional (non-robotic) laparoscopic myomectomies performed between January 2004 and December 2024 at a single UK university hospital. Primary outcomes were estimated blood loss (EBL), length of hospital stay (LOS) and operating time. Secondary outcomes were blood transfusion rate, conversion to laparotomy and analysis of fibroid burden by ethnicity. Outcomes were compared between patients with large fibroids (>10 cm), high-order fibroids (>10 fibroids removed), both and neither. We performed inferential descriptive statistics using SPSS v27 (SPSS Inc., Chicago, IL). Among 550 patients, 164 had large fibroids, 30 high-order fibroids, 18 both and 338 neither. Ethnic minority patients represented 77%, 93%, 89% and 72% of these groups, respectively. Mean EBL was higher in large fibroid (345 mL) and combined groups (483 mL) compared with neither (211 mL), without associated increases in transfusion, conversion to laparotomy, or LOS. Black African and Black Caribbean patients had greater fibroid burden and higher blood loss than Caucasian patients, reflecting disease severity rather than ethnicity as an independent determinant of outcome. In a specialist setting, laparoscopic myomectomy is feasible and safe for patients with large and/or multiple fibroids, including those from ethnic minority backgrounds with higher disease burden. Expansion of access within appropriately resourced centres may help reduce inequities in fibroid care.

Factor affecting lymph node metastasis in uterine papillary serous carcinomas: a retrospective analysis

The aim of this study was to investigate the risk factors for lymph node metastasis (LNM) in patients with uterine serous cancer (USC) who underwent systematic staging surgery. Eighty patients who were operated on for pure uterine serous papillary carcinoma between 2008 and 2020 in our clinic were retrospectively analysed. The effects of demographic information and clinicohistopathological characteristics of the included patients on LNM were examined. The median age of the patients included in the study was 64.3 and the tumour diameter was 3.8 cm. At the time of diagnosis, 65.8% of the cases were in the advanced stage, while 34.2% were in the early stage. There was no LNM in 42 (52.5%) of the cases, only pelvic in six (7.5%), only paraaortic LNM in four (5%) patients, and both pelvic and paraaortic LNM in 24 (30%) patients. When factors that may affect LNM were evaluated with multivariate analysis, lymphovascular space invasion (LVSI) and cytology positivity were found to be independent risk factors (

Predictability of lymph node involvement in uterus-confined endometrioid endometrial cancer by tumour size, pattern and location measured with transvaginal ultrasonography: can we save time?

We aimed to investigate whether transvaginal ultrasonography (TVUSG)-measured tumour size, pattern and location were significant predictors for lymph node metastasis in the uterus-confined endometrioid endometrial cancer (EEC) patients. A total of 213 patients with EEC were recruited and 73 of them were considered eligible and were analysed according to lymph node involvement. Tumour size, pattern and location measured by transvaginal ultrasound were recorded. Thereafter, patients were distributed according to their lymph node involvement and were compared with respect to these parameters. The patients' median age was 56 (27-80). Mean of the resected lymph nodes was 29.68 and 33.5 in lymph-node-negative and positive patients, respectively (

Microsatellite instability and oncological outcomes in Thai patients with endometrial cancer

Here, we determined the frequency of microsatellite instability (MSI) and the impact of MSI-high (MSI-H) on clinical outcomes of Thai patients with endometrial cancer (EC). Tissue samples of 110 Thai patients with EC, who had undergone surgical staging, were tested for mismatch repair (MMR) gene deficiency, and the patients were grouped into MSI-H and MSI-stable (MSI-S) groups; 24.5% had MSI-H. Unlike MSI-S group patients, MSI-H group patients had synchronous and metachronous cancer. They showed better 3-year disease-free survival (DFS) than those in the MSI-S group (

Long-term risk of uterine malignancies in women with uterine fibroids confirmed by myomectomy: a population-based study

Leiomyosarcomas may originate from pre-existing uterine fibroids. However, recent studies showed that leiomyosarcomas do not arise from malignant changes in fibroids. Epidemiological data on the long-term risk of uterine malignancy with uterine fibroids are lacking. We aimed to determine whether uterine fibroids are a risk factor for uterine cancer. Patient data (2007-2020) from the Korean Health Insurance program were obtained. Using the procedure and diagnostic codes, data from patients who underwent myomectomy and appendicitis (control group) were extracted Using 1:1 propensity-score matching, 84,507 women were each allocated to the uterine fibroids and control groups. Endometrial cancer occurred in 36 44 and 44 36 women in the uterine fibroids and control groups (

The accuracy and clinical impact of intraoperative frozen section in determining the extent of surgical intervention in patients with early stage endometrial cancer

The aim of this study was to compare intraoperative frozen section (FS) with the final pathology (FP), and determine its clinical impact in clinically apparent early stage endometrial cancer (EC) at the American University of Beirut Medical Center (AUBMC). Data for patients 18 years or older, with clinically apparent early stage, grade 1 or 2, endometrioid EC, who underwent hysterectomy ± lymph node dissection (LND) at AUBMC between January 1

Uterine sparing management in patients with endometrial cancer: a narrative literature review

Endometrial cancer is the most common malignancy of the female genital tract. Approximately 25% of cases occur in premenopausal women, and up to 5% of cases occur in women who are younger than 40 years old. The survival rate in these cases is 99%; therefore, uterine-sparing management could be considered under strict criteria selection and the strong desire of the woman to preserve uterus and fertility. Diagnosis should be performed after a hysteroscopic biopsy instead of dilatation and curettage. The highest remission rate was achieved after combining a hysteroscopic resection with hormonal therapy compared to single hormonal treatment. The most common regiments are the following progestins: megestrol acetate (MA) and medroxyprogesterone acetate (MPA) taken orally with a daily dosage of 160 mg-320 mg for MA and 250 mg-600 mg for MP. Evaluations at three and six months could be performed by office endometrial biopsy and/or hysteroscopic directed biopsy especially in the presence of levonorgestrel intrauterine system, and in cases of remission, either a pregnancy attempt or maintenance therapy should be considered. After childbearing, hysterectomy with bilateral salpingo-oophorectomy is recommended, whereas ovarian preservation could be considered depending on the patient's age and whether they fulfil the strict criteria selection.

The effect of adenomyosis on endometrial cancer: a university hospital-based cohort study

Endometrial cancer (EC) can coexist with gynaecological diseases including adenomyosis which can be defined as the location of endometrial cells within the myometrium. Our aim was to clarify the impact of adenomyosis on the clinical and survival outcomes of EC. We included the patients who underwent an operation for EC and had concurrent adenomyosis in this retrospective cohort study. All clinicodemographical and tumour characteristics with survival outcomes of the patients were analysed comparatively. A total of 763 patients who met the eligibility criteria were included. Of those, 591 patients in the non-adenomyosis group and 172 patients in the adenomyosis group were examined. Disease-specific survival (DSS) was significantly prolonged while progression-free survival (PFS) was not affected by the presence of adenomyosis (

Laparoscopic assessment improves case selection for exenterative surgery in recurrent cervical and endometrial cancer

The objective of this study is to evaluate the role of laparoscopy in the case selection of patients for pelvic exenteration to treat recurrent cervical or endometrial cancer. Pelvic exenteration is a rare surgical procedure performed by specialised multidisciplinary surgical teams. We performed a review of 55 consecutive laparoscopies for patients being evaluated for possible exenterative surgery for recurrent cervical or endometrial cancer at a single centre in the UK with a significant exenterative surgical practice. All patients had no evidence of metastatic disease on imaging prior to the laparoscopy. Despite thorough radiological assessment laparoscopy detected peritoneal, nodal or extrapelvic metastases in 20.8% of cases. 5.6% of the patients who underwent exenterative surgery were found to have unresectable pelvic disease intraoperatively. In these cases, the extent of disease was not determined radiologically or during the initial exploratory laparotomy. In our view, laparoscopic assessment is an essential component of the pre-operative work up of patients with recurrent cervical or endometrial cancer being considered for exenterative surgery.Impact statement

A single centre experience of metabolic syndrome and endometrial carcinoma: 5 years review

Endometrial cancer (EC) has been found to have a strong association with overweight and obesity. The aim of this study was to evaluate the link between metabolic syndrome and EC among patients. A total of 119 patients with histologically confirmed EC were recruited. About 102 cases of endometrioid carcinoma (Type I) and serous (

Confounding factors of transvaginal ultrasound accuracy in endometrial cancer

Endometrial cancer is the most frequently diagnosed gynecological tumour. Transvaginal ultrasound has a leading role in the preoperative evaluation of endometrial cancer patients. The study aimed to identify factors that can worsen the diagnostic accuracy of transvaginal ultrasound in endometrial cancer patients. We retrospectively analysed 290 patients with histological diagnosis of endometrial adenocarcinoma. Two-dimensional (2D) gray-scale ultrasound and power Doppler imaging were performed. Age, menopause status, obesity, parity, Figo stage and benign uterine disorders were evaluated as possible factors worsening the diagnostic accuracy of the ultrasonography. FIGO stage IB was the main significant confounding factor in the univariate analysis (

Usefulness of sentinel lymph node mapping using indocyanine green and fluorescent imaging in the diagnosis of lymph node metastasis in endometrial cancer

The lymph node status is the most important prognostic factor for endometrial cancer. This study aimed to assess whether sentinel lymph node mapping (SLNM) is applicable in endometrial cancer. A retrospective review of patients with endometrial cancer who were diagnosed and treated in Asan Medical Centre from September 2015 to December 2017 was conducted. One hundred patients underwent robotic (da Vinci®) or laparoscopic surgical treatment, including SLNM with indocyanine green (ICG) fluorescence detection using the Firefly® and NIR/ICG systems. At least one lymph node area was observed in 100% of SLNM cases. Sentinel node detection and frozen biopsy were performed in all cases, and all patients with metastasis were found on SLNM. The sensitivity and negative predictive value were both 100% in the patient-by-patient and station-by-station analyses. SLNM appears to be a feasible method to reduce the morbidity and increase the detection rate in early-stage endometrial carcinoma.

Comparison between laparoscopic and robotic surgery for sentinel lymph node mapping in endometrial cancer using indocyanine green and near infra-red fluorescence imaging

Indocyanine green (ICG) and near infra-red fluorescence imaging in minimally invasive surgery is an option to map sentinel lymph nodes (SLN). The aim of this study was to compare the outcomes of SLN mapping between laparoscopic and robotic surgery. One-hundred-and-forty women with histologically confirmed endometrial cancer, were treated with a minimally invasive hysterectomy, bilateral salpingo-oophorectomy and SLN mapping. After anaesthetic induction, ICG was superficially injected into cervical submucosa and deeply injected into the cervical stroma at the 3 and 9 o'clock positions (1.25 mg/site). Eleven cases were abandoned after ICG injection (laparoscopic surgery seven cases and robotic surgery four cases) because of obesity, technical difficulty and peritoneal disease. One-hundred-and-eleven patients were analysed. Seventy-six patients had a laparoscopic procedure and 33 patients had robotic surgery. The overall and bilateral detection rates were 97% and 83% for laparoscopic surgery and 88% and 73% for robotic surgery. Laparoscopic surgery was superior to robotic surgery in terms of overall detection (

Multi-institutional validation of the ESMO-ESGO-ESTRO consensus conference risk grouping in Turkish endometrial cancer patients treated with comprehensive surgical staging

In this study, 683 patients with endometrial cancer (EC) after comprehensive surgical staging were classified into four risk groups as low (LR), intermediate (IR), high-intermediate (HIR) and high-risk (HR), according to the recent consensus risk grouping. Patients with disease confined to the uterus, ≥50% myometrial invasion (MI) and/or grade 3 histology were treated with vaginal brachytherapy (VBT). Patients with stage II disease, positive/close surgical margins or extra-uterine extension were treated with external beam radiotherapy (EBRT)±VBT. The median follow-up was 56 months. The overall survival (OS) was significantly different between LR and HR groups, and there was a trend between LR and HIR groups. Relapse-free survival (RFS) was significantly different between LR and HIR, LR and HR and IR and HR groups. There was no significant difference in OS and RFS rates between the HIR and HR groups. In HR patients, the OS and RFS rates were significantly higher in stage IB - grade 3 and stage II compared to stage III and non-endometrioid histology without any difference between the two uterine-confined stages and between stage III and non-endometrioid histology. The current risk grouping does not clearly discriminate the HIR and IR groups. In patients with comprehensive surgical staging, a further risk grouping is needed to distinguish the real HR group.Impact statement

The investigation of serum levels of ADAMTS 5 and 8 (the A disintegrin and metalloproteinase with thrombospondin motifs) in the etiology of endometrial cancer

The aim of this study was to investigate the serum levels of the A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) 5 and 8 in patients diagnosed with endometrial cancer. Our study included 41 patients diagnosed with endometrial cancer. The control group consisted of 41 patients diagnosed with benign endometrial pathology. The serum samples were centrifuged and stored at -80 °C. The serum levels of ADAMTS were significantly higher (

Arsenic trioxide in the treatment of platinum-resistant recurrent endometrial cancer: a case report and literature review

Does a history of malignancy impact the survival of a subsequent endometrial adenocarcinoma? Should clinical trials eligibility criteria be revisited?

We aimed at finding the impact of prior malignancies on the survival of patients with endometrial adenocarcinoma using SEER database (from 1973 to 2014). We identified 127,988 patients who were diagnosed with endometrial adenocarcinoma (6485 had a prior malignancy), and we compared the overall and cancer-specific survival based on the presence or absence of a prior malignancy and the latency period between the two diagnoses using Kaplan-Meier test and Cox models. Adjusted cox models showed that a history of a prior malignancy neither affected the overall survival nor the cancer-specific survival of stage IV cases in all latency groups except the one diagnosed within 1 year of the first cancer. Therefore, there is no rational explanation for excluding stage IV endometrial adenocarcinoma patients with a prior malignancy from clinical trials except for the group that was diagnosed with endometrial adenocarcinoma within 1 year from the first cancer.Impact statement

The role of urine and serum biomarkers in the early detection of ovarian epithelial tumours

Ovarian cancer (OC) is one of the leading causes of gynaecological cancer mortality in women worldwide. If detected at an early stage (I, II), OC has a 90% 5-year survival rate; nevertheless, symptoms are often hidden, leading to late-stage (III, IV) diagnosis and a poor prognosis. The current diagnostic procedures, such as a pelvic exam, transvaginal ultrasound, CA-125 blood tests, serum HE4 tests and multivariate index assays (MIA), are insufficient. Sadly, surgery is frequently required to confirm a positive diagnosis. Therefore, there has been an increased interest in different biomarkers using a non-invasive test as a tool for the earlier diagnosis of OC to resolve the need for precise and non-invasive diagnostic methods. This review article aims to investigate how biomarkers influence early OC detection and to emphasise the role of using a combination of serum biomarkers panel rather than a single biomarker. In addition, this review provides insights into the current serum biomarkers, urine biomarkers and other emerging biomarkers in the early detection of OC for better specificity and sensitivity and to improve the overall survival (OS) rate.

Sentinel lymph node biopsy based on anatomical landmarks and locoregional mapping of inguinofemoral sentinel lymph nodes in women with vulval cancer: an operative technique

Inguinal lymph node involvement is the most robust predictor of mortality in vulval cancer and sentinel lymph node (SLN) biopsy is a safe diagnostic modality. We describe a technique based on anatomical landmarks. Our aims are (1) to describe the territorial mapping of SLNs, (2) to evaluate the associated complication rate vis-à-vis those reported in the literature, and (3) to assess its accuracy in detecting SLNs. Data from women who underwent groin SLN biopsies for vulval cancer at a single cancer centre were prospectively collected. All subjects met the GROINSS-V eligibility criteria. The location of the SLN relative to the saphenous vein was recorded. All women were followed up and early and late complications were recorded. The recurrence rate at the time of the census was calculated. A total of 71 groins in 44 women were included. The SLN was primarily located over Cloquet's node (85.2%). The incidence of early wound cellulitis and dehiscence were 2.8% and 11.3% while lymphocysts were present in 11.3% of groins. The negative nodal recurrence rate was 1.7%. Results showed that this reproducible technique allows access to 96.7% of SLNs, including both deep and superficial SLNs whilst minimising the need for extensive dissection and complications associated with overharvesting of lymph nodes.

Identification of potential prognostic biomarkers in vulval squamous cell carcinoma based on human papillomavirus infection Status-Analysis of GSE183454

This study aimed to elucidate the differences in vulval squamous cell carcinomas (VSCC) based on the HPV infection status. The sequencing data GSE183454 which contains 23 VSCC samples based on its HPV infection status was obtained from the Gene Expression Omnibus (GEO) database. We comprehensively dissected the differences of genomic and tumour microenvironment (TME) immune cell infiltration landscapes between HPV + and HPV- VSCC. The potential molecular mechanisms of prognostic genes were explored by functional enrichment analysis. Five novel key molecules (SYCP2, SMC1B, RNF212, MAJIN and C14orf39) with significantly up-regulated expression in HPV + VSCC were identified while protein-protein interaction (PPI) networks were created upon Cytoscape software. Additionally, VSCC with up-regulated expression of these key molecules exhibited a significantly decreased TME immune cell infiltration. SYCP2 is overexpressed in HPV + VSCC and could be a candidate therapy target for further research.IMPACT STATEMENT

Association between ABO blood type and type I endometrial cancer: a retrospective study

This study aimed to assess the association between ABO blood type and incident of type I endometrial cancer (EC), as well as the stage and differentiation. 213 patients with type I EC and 300 healthy controls were included. As a result, the frequencies of A, B, O, and AB blood types among patients with type I EC were 51 (23.9%), 59 (27.7%), 93 (43.7%) and 10 (4.7%), respectively. There were no significant differences in age, body mass index, and other baseline covariates between groups of ABO blood types (

Postoperative early mobilisation protocol for endometrial cancer patients: a retrospective study

Standardised early mobilisation within Enhanced Recovery After Surgery (ERAS) for endometrial cancer is lacking. This study developed and evaluated a protocol. This retrospective study analysed outcomes of a clinical quality improvement initiative conducted at a tertiary care centre (February 2021-May 2022). The intervention group was associated with significantly better first ambulation (6.8 ± 2.1 h vs. 18.5 ± 4.3 h, mean difference: 11.7 h, 95% CI: 10.3-13.1, This retrospective analysis suggests that the structured early mobilisation protocol, implemented as a clinical quality improvement initiative, was associated with improved recovery, reduced complications/LOS and better emotional wellbeing in endometrial cancer patients within ERAS.

GLP1R boosts survival, migration and invasion of endometrial cancer cells and protects against ferroptotic cell death

Despite the strong evidence concerning carcinogenic roles of glucagon-like peptide 1 receptor (GLP1R), the role of this gene in endometrial cancer (EC) remains elusive. This study investigated the properties of GLP1R on EC The expression of GLP1R in EC was detected by RT-qPCR, immunohistochemistry, and western blotting. Cell viability, cell cycle, apoptosis, migration, invasion and ferroptosis were assessed through CCK-8, flow cytometry, wound healing, transwell, DCFH-DA and western blotting, respectively. We found that GLP1R was up-regulated in EC than normal specimens. It had the highest expression in AN3CA cells. Cell viability, migration and invasion were significantly reduced, while cell cycle arrest and apoptosis were induced following GLP1R knockdown. The malignant biological behaviours of AN3CA cells were investigated when treated with exendin-4 (GLP1R agonist). Moreover, GLP1R lowered intracellular ROS level and expression of SLC7A11, and FTH1, but mitigated GPX4 expression in AN3CA cells. In a word, GLP1R was up-regulated in EC and its up-regulation facilitated the proliferative and metastatic potentials, and protected cells from ferroptosis, thereby accelerating EC progression. These data emphasised the potency of GLP1R as a therapeutic agent against EC.

Integrated bioinformatic and experimental study links cyclin B1/B2 to poor prognosis and immune infiltration in endometrial cancer

Although most cases of endometrial cancer (EC) are diagnosed at an early stage with favourable outcomes, the prognosis for advanced or recurrent disease remains poor, highlighting the need for novel therapeutic targets. This study aimed to examine the correlation between Cyclin B1 (CCNB1) and Cyclin B2 (CCNB2) expression and disease severity in EC through bioinformatics analysis. Common differentially expressed genes were identified in two EC cohorts from the Gene Expression Omnibus. A protein-protein interaction (PPI) network was constructed to identify hub genes. Aberrant expression of the hub genes was validated in external datasets. Their prognostic values were evaluated in a cohort from The Cancer Genome Atlas (TCGA). Knockdown of the hub genes was conducted to explore their functions in the malignant behaviour of EC cells CCNB1 and CCNB2 were identified as the top 2 hub genes in the PPI network. High CCNB1/CCNB2 expression was significantly associated with shorter survival in EC patients. Overexpression of CCNB1/CCNB2 in endometrial tumour tissue was validated in public datasets. In TCGA cohort, high expression of CCNB1/CCNB2 correlated with greater disease severity and predicted poor prognosis. In addition, high expression of CCNB1/CCNB2 was strongly associated with immune cell infiltration, as well as increased expression of immune checkpoint genes and mismatch repair genes. Furthermore, knockdown of CCNB1/CCNB2 significantly suppressed the proliferation, migration, and invasion of HEC-1 and Ishikawa cells CCNB1 and CCNB2 may serve as potential prognostic markers and therapeutic targets for the management of EC.

Immune cell phenotype in endometrial cancer: from biological significance to clinical utility using Mendelian randomisation analysis

We investigated the relationship between immune cells and endometrial cancer by conducting a two-sample bidirectional Mendelian randomisation (MR) analysis. MR uses genetic variation as an instrumental variable to study the causal effects of exposure on observed data outcomes. We conducted a dual-sample MR analysis to investigate the causal relationship between 731 immune cell phenotypes and endometrial cancer (EC). The weighted-median method and inverse variance weighted method MR were mainly used, and the The forward MR analysis revealed a causal relationship between EC and eight immune-cell phenotypes. The reverse MR analysis identified two immune-cell phenotypes with a potential causal effect on EC, with additional subtype-specific associations observed for endometrioid and non-endometrioid histology. Our study demonstrated a causal relationship between immune cells and EC, thereby providing guidance for the development of future immunoregulatory therapeutic strategies.

Abnormal preoperative haematological parameters in Endometrial cancer; reflecting tumour aggressiveness or reduced response to radiotherapy?

In endometrial cancer (EC), preoperative anaemia, thrombocytosis and leucocytosis appear to be associated with worse prognosis. It remains unclear whether these parameters solely reflect tumour aggressiveness, or also impact response to adjuvant treatment. Therefore, our primary aim is to evaluate the prognostic relevance of anaemia, thrombocytosis and leucocytosis on survival in EC. Secondary, to explore their predictive relevance in response to radiotherapy in EC. A retrospective multicentre cohort study was performed within 10 hospitals. Preoperative haematological parameters were defined as: Anaemia - haemoglobin 400 × 10 A total of 894 patients were included with a median follow-up of 4.5 years. Anaemia was present in 103 (11.5%), thrombocytosis in 79 (8.8%) and leucocytosis in 114 (12.7%) patients. The presence of anaemia or thrombocytosis was significantly associated with ESGO/ESTRO/ESP high-risk (respectively, Current data demonstrate the importance of preoperative anaemia as independent prognostic factor in patients with EC. Moreover, anaemia seems to be associated with reduced response to radiotherapy. Prospective validation in a larger study cohort is needed to verify anaemia as predictive biomarker for radiotherapy.

Factors affecting the postoperative survival rate of obese Asian patients with endometrial cancer

The objective of this study was to explore the factors that influence overall survival in obese patients with endometrial cancer (EC). The retrospective study included patients with EC who were treated between 2000 and April 2013. Subjects were divided into the following groups based on body mass index (BMI): non-obese (<24.0 kg/m A total of 280 cases were enrolled, including 22.5% in non-obese group, 42.9% in overweight group and 34.6% in obese group. Among different BMI groups, obese EC patients with diabetes have a lower survival rate ( Our data suggest that the association of obese EC patients with menstrual status, diabetes and intraoperative vasculature embolus and lymph node metastasis significantly affects postoperative survival. In all subjects, the relevant factors were independent prognostic factors in patients with obese.

MRI as an assessment tool for prognostic risk stratification of endometrial carcinoma patients based on molecular classification

Non-invasive risk stratification for patients with endometrial carcinoma (EC) is important for developing personalised treatment plans. Our study aimed to explore the ability of quantitative MRI parameters to predict the risk stratification of EC patients based on molecular classification. Fifty-three patients with histologically proven EC who underwent pelvic MRI and surgical treatment at our hospital between January 2020 and August 2022 were assessed. The tumour volume (TV) and uterine volume (UV) were estimated with the ellipsoid formula and used to calculate the tumour volume ratio (TVR). The mean apparent diffusion coefficient (ADC) of the tumour was measured on a workstation. Quantitative MRI parameters were compared among different risk groups via unpaired Student's The TV and TVR were significantly different between the low- and high-risk groups ( Quantitative MRI parameters such as the TV, TVR and ADC may be helpful in preoperatively assessing the risk stratification of patients with EC based on molecular classification.

Circular RNA differential expression profiles and bioinformatics analysis of hsa_circRNA_079422 in human endometrial carcinoma

The aim of our study was to explore circular RNA (circRNA) expression profiles associated with human endometrial carcinoma (EC) and to analyse the molecular mechanisms involved in cancer development and their potential clinical importance. Differential expression profiles were revealed by Arraystar human circRNA microarray analysis. The results of the circRNA microarray were confirmed by quantitative real-time PCR. Interactions between circRNAs and microRNAs (miRNAs) were predicted using Arraystar's miRNA target prediction software. The functions of the circRNA-miRNA coexpression network were identified by KEGG pathway analysis and GO analysis. Compared with para-tumorous tissues, 14 genes were significantly upregulated and 12 genes were significantly downregulated in EC tissues (

Bioinformatics analysis of the clinicopathological and prognostic significance of BAG3 mRNA in gynecological cancers

BAG3 is a co-chaperone BAG family protein that plays important roles in protein homeostasis, cell survival, cell motility, and tumour metastasis. This study aimed to clarify the clinicopathological and prognostic implications of

Survival benefit of surgical treatment for patients with stage IVB endometrial cancer: a propensity score-matched SEER database analysis

The study aimed to evaluate the value of cancer-directed surgery (CDS) in improving the prognosis of patients with stage IVB endometrial cancer (EC) and under which kind of conditions could maximise its value. The Surveillance, Epidemiology, and End Results database was used to analyse patients diagnosed with stage IVB EC who received chemotherapy between 2004 and 2016. Among 1978 patients were enrolled following propensity score matching (PSM). We found that CDS was closely associated with prolonged overall survival. Moreover, CDS can effectively improve the survival rate of patients with protective or unfavourable factors and should be considered in a range of circumstances. Almost all patients (96.15%) who received surgery were operated on primary tumours of the reproductive organs and obtained favourable surgical outcomes. In conclusion, surgery can improve the survival of patients with stage IVB EC, palliative hysterectomy is worth considering in such patients.IMPACT STATEMENT

The bioinformatics analysis of the clinicopathological and prognostic significances of REG4 mRNA in gynecological cancers

To clarify the clinicopathological importance of REG4 mRNA expression, we used GEO, TCGA, xiantao, UALCAN, and Kaplan-Meier plotter for a bioinformatics analysis in breast, cervical, endometrial and ovarian cancers. Compared to normal tissues, REG4 expression was found to be upregulated in breast, cervical, endometrial, and ovarian cancers (p < 0.05). Breast cancer had a higher level of REG4 methylation than normal tissues (

Assessment of knowledge, understanding and awareness of Chinese women clinical staff towards menopause hormone therapy: a survey study

Menopausal Hormone Therapy (MHT) is recommended for climacteric peri- and postmenopausal symptoms. The rate of use of MHT in China is much lower than the western regions. Therefore, a survey was conducted for the understanding and utilization of MHT among clinical staff in various hospitals of China. A total of 3216 eligible questionnaires were included for the evaluation. According to 19.2% participant opinion, MHT could relieve menopausal symptoms, whereas the majority had no knowledge of the benefits and risks of MHT. The most common concern about MHT was the risk of cancer and about 430 (13.4%) and 176 (5.5%) participants were apprehensive that MHT could increase the risk of breast and endometrial cancer, respectively. This survey demonstrated that the knowledge of clinical staff was not comprehensive and they should be educated more about the use of MHT so that this knowledge can be imbibed into the general population.Impact Statement

Correlation of plasma adipokines with endometrial atypical hyperplasia and type I/II endometrial cancer

The aim of the study was to systematically explore the relationships between various adipokines and risks of endometrial atypical hyperplasia (EAH), type I endometrial cancer (EC), and type II EC. We enrolled 219 patients in this study, including 39 EAH, 87 type I EC, 38 type II EC and 55 control individuals. We subsequently explored the association of adipokine levels and the leptin-to-adiponectin (L/A) ratio with EAH, type I EC, and type II EC. The plasma leptin level and L/A ratio were significantly higher in the EAH group than in the control group (

The differential expression of AFF3 in cervical cancer and its correlation with clinicopathological features and prognosis

Cervical cancer (CC) is the second most common malignancy in women, and identifying biomarkers of CC is crucial for prognosis prediction. Here, we investigated the expression of AF4/FMR2 Family Member 3 (AFF3) in CC and its association with clinicopathological features and prognosis. Tumour and adjacent tissues, along with clinicopathological features and follow-up information, were collected from 78 patients. AFF3 expression was assessed using quantitative real-time polymerase chain reaction and Western blotting. The correlation between AFF3 expression and CC symptoms was using chi-square test. The 5-year overall survival (OS) was analysed using the Kaplan-Meier method. The Univariate analysis of prognostic risk factors was conducted using the COX proportional hazards model, followed by multivariate COX regression analysis including variables with AFF3 expression was downregulated in CC, and its levels were correlated with lymph node metastasis (LNM) and International Federation of Gynaecology and Obstetrics (FIGO) stage. Patients with low AFF3 expression had a lower 5-year OS rate (52.78%, 19/36). Postoperative survival was reduced in patients with histological grade 3 (G3), myometrial invasion (depth ≥ 1/2), lymphovascular space invasion, LNM, and advanced FIGO stage. Low expression of AFF3 (HR: 2.848, 95% CI: 1.144-7.090) and histological grade G3 (HR: 4.393, 95% CI: 1.663-11.607) were identified as independent prognostic risk factors in CC patients. Low expression of AFF3 and histological G3 are independent predictors of poor prognosis in CC patients, suggesting that AFF3 could serve as a potential biomarker for prognostic assessment in CC.

LINC01094 targets miR-1266-5p to halt neoplasm progression of cervical cancer

To investigate the mechanism and prognostic value of LINC01094 in cervical cancer (CC). This study included 113 patients with CC. Their cervical tumour tissues and tumour-free cervical tissues were collected, with patient follow-up for a five-year prognostic period. Reverse transcription-quantitative PCR (RT-qPCR) was used to identify LINC01094 and measure miR-1266-5p expression, Kaplan-Meier curves were used to predict patient survival, and multivariate Cox regression analysis revealed the factors affecting CC prognosis. A dual luciferase reporter (DLR) assay was performed to verify the targeting relationship of reciprocal genes. The Cell Counting Kit-8 (CCK8) assay was used to measure cell proliferation, and the Transwell recorded cell migration and invasion. Lower LINC01094 expression and higher level of miR-1266-5p expression were detected in-tumour tissues than in the tumour-free cervical tissues, with a negative correlation. Low LINC01094 expression, International Federation of Gynaecology and Obstetrics (FIGO) stage, and lymph node metastasis were identified as risk factors for CC prognosis, LINC01094 downregulation predicted higher patient mortality. The DLR assay identified miR-1266-5p as a possible target gene of LINC01094. Additional experiments revealed miR-1266-5p downregulation and decreased cell proliferation, migration and invasion of CC cells transfected with oe-LINC01094. These effects were restored after co-transfection with miR-mimic. Low LINC01094 expression in patient with CC is a risk factor for prognosis. Overexpression of LINC01094 targeting miR-1266-5p prevents the progression of CC neoplasm.

Prognostic value of systemic immune-inflammation index in cervical cancer: a systematic review and meta-analysis

A growing body of evidence indicates that the systemic immune-inflammation index (SII) is associated with the prognosis of cervical cancer (CC). However, its prognostic value remains controversial. This study aimed to comprehensively evaluate the performance of SII in predicting the prognosis of CC. Studies on the prognostic potential of SII in CC were acquired from PubMed, Embase, Web of Science, and the Cochrane Library from database inception to July 4, 2024. Outcome measures included progression-free survival (PFS), overall survival (OS), relapse-free survival (RFS), and complete response (CR), which were expressed as hazard ratio (HR) and 95% confidence interval (CI). Sensitivity and subgroup analyses were carried out to evaluate the stability of results and identify potential sources of heterogeneity. Ten cohort studies involving 2007 patients were included in the meta-analysis. High SII levels were significantly associated with reduced OS (HR = 2.45; 95% CI: 1.56-3.86, High SII levels are significantly associated with reduced OS, PFS, and CR in CC. Therefore, SII is a promising biomarker for predicting outcomes and informing treatment decisions for immunotherapy in CC.

Demographics of epithelioid trophoblastic tumour and placental site trophoblastic tumour: a 21 year UK population study

Epithelioid and placental site trophoblastic tumours are rare gestational malignancies which have little detailed information on their population incidence or risk related to maternal age. We performed a retrospective UK national population-based study examining all of the cases registered between 2000 and 2020 using the databases at the UK's two gestational trophoblastic treatment centres at Charing Cross Hospital in London and Weston Park Hospital in Sheffield. The data obtained was compared with the contemporary UK birth and pregnancy statistics. Over the 21-year study period, there were 132 cases of ETT or PSST. PSTT comprised 57% of the cases, 30% were ETT and 13% had mixed pathology. The combined incidence of ETT and PSTT was 1:118,736 relative to live births and 1:150,872 compared to total viable conceptions. For women aged under 20 the incidence relative to live births was 1:412,488, increasing to 1:188,292 for women 30-34 years, and 1:1,426 for women aged 45 and above. The median interval from the antecedent pregnancy to the time of diagnosis was 15 months (0-288) for the PSTT patients compared to 24 months (0-336) for patients with a diagnosis of ETT. ETT and PSTT are both rare diagnoses with little detailed information on their demographics. The data in this study indicates a wide range in the interval from the antecedent pregnancy to diagnosis and confirms a close relationship between increasing incidence and rising maternal age.

Application of WeChat-based cognitive behavioural stress management for early-stage cervical cancer patients: a randomised controlled study

This randomised controlled study was aimed at investigating the effects of WeChat-based cognitive behavioural stress management (WB-CBSM) on the mental health of patients with early-stage cervical cancer treated with surgical resection. A total of 184 patients with early-stage cervical cancer were randomised to receive either WB-CBSM ( Compared with the NC group, the WB-CBSM group exhibited reduced Hospital Anxiety and Depression Scale (HADS)-anxiety scores at months (M)1 ( WB-CBSM reduced anxiety and depression and improved the spiritual well-being and quality of life of patients with early-stage cervical cancer treated with surgical resection.

Meta-analysis of efficacy and safety of pembrolizumab for the treatment of advanced or recurrent cervical cancer

This meta-analysis seeks to assess the efficacy and safety of pembrolizumab in individuals with advanced or recurrent cervical cancer. Databases from PubMed, Embase, and the Cochrane Library were all thoroughly searched for pertinent research. Outcomes include complete response (CR), partial response (PR), stable disease (SD), disease progression (PD), overall response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), median overall survival (mOS), and adverse events (AEs) were retrieved for further analysis. Ten trials with 721 patients were included in this meta-analysis. The pooled results for patients with cervical cancer receiving pembrolizumab were as follows: CR (0.06, 95%CI: 0.02-0.10), PR (0.15, 95%CI: 0.08-0.22), SD (0.16, 95%CI: 0.13-0.20), PD (0.50, 95%CI: 0.25-0.75), ORR (0.26, 95%CI: 0.11-0.41) and DCR (0.42, 95%CI: 0.13-0.71), respectively. Regarding survival analysis, the pooled mPFS and mOS were 3.81 and 10.15 months. Subgroup analysis showed that pembrolizumab in combination was more beneficial in CR (0.16 vs. 0.03, For patients with advanced or recurrent cervical cancer, this systematic review and meta-analysis demonstrated that pembrolizumab had a favourable efficacy and tolerability. Future research will primarily focus on optimising customised regiments that optimally integrate pembrolizumab into new therapies and combination strategies. Designed to maximise patient benefit and efficiently control adverse effects while maintaining a high standard of living.

The association between affordable care act implementation and the prevalence of women having ever received a Pap smear

To assess if implementation of the 2010 Patient Protection and Affordable Care Act (ACA) was associated with changes in the prevalence of women having ever received a pap smear. This study utilised the publicly available Centre for Disease Control National Survey of Family Growth (NSFG) data set. This was a serial cross-sectional study. The comparison groups were defined as women who received cancer screening and prevention interventions prior to full implementation of the ACA (2011-2013) and post full implementation (2017-2019). The primary outcome was self-reporting receipt of a Papanicolaou (Pap) smear. Secondary outcomes included HPV vaccination and mammogram rates. Anonymized patient information was collected from the nationally representative dataset, and analyses were performed utilising STATA 18. The two study cohorts obtained from the NSFG included women who responded in 2011-2013 ( A decrease in proportion of women ever having had a Pap smear despite implementation of health policies to increase access to preventive measures suggests further interventions to improve access to cervical cancer screening are warranted.

Prediction of outcomes after chemoradiotherapy for cervical cancer by neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio

Cervical cancer ranks as the second most fatal tumour globally among females. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been widely applied to the diagnosis of cancers. The clinicopathologic data of 180 patients with stage IB2-IIB cervical cancer who underwent radical concurrent chemoradiotherapy from January 2018 to December 2019 were retrospectively analysed. Receiver operating characteristic (ROC) curves were plotted to analyse the optimal cut-off values of NLR and PLR for predicting the therapeutic effects of concurrent chemoradiotherapy. The associations of PLR and other clinicopathological factors with 1-year survival rates were explored through univariate analysis and multivariate Cox regression analysis, respectively. NLR was significantly associated with the therapeutic effects of neoadjuvant therapy, with the optimal cut-off value of 2.89, area under the ROC curve (AUC) of 0.848 (95% confidence interval [CI]: 0.712-0.896), sensitivity of 0.892 (95% CI: 0.856-0.923) and specificity of 0.564 (95% CI: 0.512-0.592). PLR had a significant association with the therapeutic effects of neoadjuvant therapy, with the optimal cut-off value of 134.27, AUC of 0.766 (95% CI: 0.724-0.861), sensitivity of 0.874 (95% CI: 0.843-0.905) and specificity of 0.534 (95% CI: 0.512-0.556). Lymphatic metastasis ([95% CI: 1.435-5.461], [95% CI: 1.336-4.281], depth of invasion ([95% CI: 1.281-3.546], [95% CI: 1.183-3.359]) and tumour size ([95% CI: 1.129-3.451], [95% CI: 1.129-3.451]) were independent factors influencing the overall survival and disease-free survival (DFS) of patients with cervical cancer. NLR (95%CI: 1.256-4.039) and PLR (95%CI:1.281-3.546) were also independent factors affecting DFS. NLR and PLR in the peripheral blood before treatment may predict DFS of patients with stage IB2-IIB cervical cancer.

Keratinocyte differentiation factor 1 enhances cervical cancer cell viability and migration by activating the PI3K/AKT pathway

The aim of This study is to investigate the effects of Keratinocyte differentiation factor 1 (KDF1) on cervical cancer cells and the underlying mechanisms. The Gene Expression Profiling Interactive Analysis database was used to analyse KDF1 expression in cervical cancer and paracancerous tissue samples. The correlation between the expression of KDF1 and clinicopathological features was also analysed. Cervical cancer cells (HeLa cells) with KDF1 overexpression or knockdown were constructed. Reverse transcription polymerase chain reaction was used to detect the mRNA expression of KDF1 in cervical cancer tissues and cells. In different treatment groups of cervical cancer cells, protein expression of KDF1, cell viability, invasion, and migration were subsequently confirmed by western blotting, CCK-8 assay, transwell assay, and wound healing assay, respectively. A PI3K inhibitor (LY294002) was used to detect the effect of KDF1 on the phosphoinositide 3-kinase (PI3K)/Protein Kinase B (AKT) pathway. KDF1 was highly expressed in cervical cancer tissues and cell lines ( KDF1 enhances cervical cancer viability and migration by activating the PI3K/AKT pathway, and may serve as a therapeutic target for patients with cervical cancer.

Impact of trainees involvement on surgical outcomes of abdominal and laparoscopic myomectomy

To determine the association of trainees involvement with surgical outcomes of abdominal and laparoscopic myomectomy including operative time, rate of transfusion, and complications. A retrospective cohort study of 1145 patients who underwent an abdominal or laparoscopic myomectomy from 2008-2012 using the American College of Surgeons National Surgical Quality Improvement Program database (Canadian Task Force Classification II-2). Overall, 64% of myomectomies involved trainees. Trainees involvement was associated with a longer operative time for abdominal myomectomies (mean difference 20.17 minutes, 95% Confidence Interval (CI) [11.37,28.97], Trainees involvement was associated with increased operative time, rate of transfusion, and complications for abdominal myomectomy, however, did not impact surgical outcomes for laparoscopic myomectomy.

Construction of a ferroptosis and hypoxia-related gene signature in cervical cancer to assess tumour immune microenvironment and predict prognosis

This study aimed to investigate the potential role of ferroptosis/hypoxia-related genes in cervical cancer to improve early management and treatment of cervical cancer. All data were downloaded from public databases. Ferroptosis/hypoxia-related genes associated with cervical cancer prognosis were selected to construct a risk score model. The relationship between risk score and clinical features, immune microenvironment and prognosis were analysed. Risk score model was constructed based on eight signature genes. Drug prediction analysis showed that bevacizumab and cisplatin were related to vascular endothelial growth factor A. Risk score, as an independent prognostic factor of cervical cancer, had a good survival prediction effect. The two groups differed significantly in degree of immune cell infiltration, gene expression, tumour mutation burden and somatic variation. We developed a novel prognostic gene signature combining ferroptosis/hypoxia-related genes, which provides new ideas for individual treatment of cervical cancer.

Human papillomavirus type 16 E7 promotes cell viability and migration in cervical cancer by regulating the miR-23a/HOXC8 axis

Human papillomavirus (HPV) is a risk factor for the occurrence of cervical cancer (CC). Here, we aimed to explore the role of HPV16 in CC and identify the underlying mechanism. The expression of miR-23a, HPV16 E6/E7 and homeobox C8 (HOXC8) was measured by quantitative real-time PCR or western blot. Cell viability and migration were evaluated using cell counting kit-8, Transwell and wound healing assays. The targeting relationship between miR-23a and HOXC8 was revealed by dual-luciferase reporter assay. miR-23a was downregulated in HPV16-positive (HPV16+) CC tissues and HPV16+ and HPV18+ cells. Additionally, E6/E7 expression was increased in CC cells. Then, we found that E7, rather than E6, positively regulated miR-23a expression. miR-23a suppressed cell viability and migration, whereas E7 overexpression abrogated this suppression. miR-23a targeted HOXC8, which reversed miR-23a-mediated cell viability and migration. HPV16 E7-mediated miR-23a suppressed CC cell viability and migration by targeting HOXC8, suggesting a novel mechanism of HPV-induced CC.

Efficacy and safety of intraperitoneal bevacizumab combined with hyperthermic intraperitoneal chemotherapy in the treatment of patients with ovarian cancer and peritoneal effusion and the effect on serum lncRNA H19 and VEGF levels

Peritoneal effusion is a common event in ovarian cancer (OC) patients. LncRNA H19 and vascular endothelial growth factor (VEGF) are implicated in cancer progression. The study evaluated the curative effect and safety of bevacizumab combined with hyperthermic intraperitoneal chemotherapy (HIPEC) in OC patients with peritoneal effusion and the effect on serum lncRNA H19/VEGF levels. Totally 248 OC patients with peritoneal effusion were treated with intraperitoneal bevacizumab + HIPEC (observation group) or abdominal paracentesis without HIPEC (control group). The clinical efficacy, quality of life, and adverse reactions were evaluated after two treatment cycles. The serum lncRNA H19 and VEGF levels pre-/post-treatment were determined by RT-qPCR and ELISA. The observation group exhibited better clinical efficacy than the control group, evidenced by a higher partial response rate, response rate, and disease control rate. The observation group exhibited reduced physical/cognitive/role/social/emotional function scores and total adverse reactions. LncRNA H19/VEGF levels showed no significant difference between the two groups before treatment but were significantly downregulated in the observation group after treatment. Summarily, intraperitoneal bevacizumab + HIPEC has significant efficacy in treating peritoneal effusion, improves the quality of life, and reduces serum lncRNA H19 and VEGF levels in OC patients, with fewer adverse reactions and higher safety.Impact statement

Novel risk prediction models, involving coagulation, thromboelastography, stress response, and immune function indicators, for deep vein thrombosis after radical resection of cervical cancer and ovarian cancer

This study aimed to investigate the predictive value of coagulation, thromboelastography, stress response, and immune function indicators for the occurrence of deep venous thrombosis (DVT) following radical resection of cervical cancer and ovarian cancer. We conducted a prospective, single-centre, case-control study that included 230 cervical cancer patients and 230 ovarian cancer patients. In the testing cohort, the final predictive model for cervical cancer patients was: Logit(P)=9.365-0.063(R-value)-0.112(K value) +0.386(α angle)+0.415(MA)+0.276(FIB)+0.423(D-D)+0.195(IL-6)+0.092(SOD). For ovarian cancer patients, the final model was: Logit(P)= -2.846-0.036(R-value)-0.157(K value) +0.426(α angle) +0.172(MA) +0.221(FIB)+0.375(CRP) -0.126(CD4

Psychological factors increase the risk of ovarian cancer

This study evaluated whether psychological stress increases the incidence of ovarian cancer. A literature search of the electronic databases PubMed and Web of Science from the date of inception to August 2022 was undertaken. Studies with data on psychosocial factors associated with ovarian cancer incidence were included in this study. A random-effect model meta-analysis was undertaken to estimate these data. We used subgroup analysis to adjust for heterogeneity. A total of 4 articles, 10 sets of data, 8 cohort studies, and 2 case-control studies from 682 records were included in this review. Meta-analyses of the included cohort study subgroups suggested that psychological factors increase the risk of ovarian cancer (effect size = 1.37, 95% CI: 1.20-1.53); the subgroup of case-control studies suggested that psychological factors did not increase ovarian cancer risk (effect size = 0.84, 95% CI: 0.70-0.98). These findings indicate that psychological stress is a possible new risk factor for ovarian cancer.

Clinical significance of the CD98hc-CD147 complex in ovarian cancer: a bioinformatics analysis

Ovarian cancer is one of the most common malignant tumours affecting the female reproductive organs. CD147 (BSG) and CD98hc (SLC3A2) are oncogenes that form the CD98hc-CD147 complex, which regulates the proliferation, metastasis, metabolism, and cell cycle of cancer cells. The roles of the CD98hc-CD147 complex in ovarian cancer remain unclear. We analysed the expression and prognostic value of CD147 and CD98hc in ovarian cancer using the TCGA and ICGC databases. The effect of CD147 and CD98hc on the tumour immune response was analysed using the TIMER database. CD98hc was more highly expressed in normal tissues than primary tumour tissues, while CD147 was more highly expressed in primary tumour tissues than normal tissues. CD98hc expression was significantly associated with neutrophil and dendritic cell levels. CD147 and CD98hc were correlated with DNA repair, the cell cycle, and DNA replication. The CD98hc-CD147 complex could serve as a target for ovarian cancer treatment.

Assessing the clinical utility of multi-omics data for predicting serous ovarian cancer prognosis

Ovarian cancer (OC) is characterised by heterogeneity that complicates the prediction of patient survival and treatment outcomes. Here, we conducted analyses to predict the prognosis of patients from the Genomic Data Commons database and validated the predictions by fivefold cross-validation and by using an independent dataset in the International Cancer Genome Consortium database. We analysed the somatic DNA mutation, mRNA expression, DNA methylation, and microRNA expression data of 1203 samples from 599 serous ovarian cancer (SOC) patients. We found that principal component transformation (PCT) improved the predictive performance of the survival and therapeutic models. Deep learning algorithms also showed better predictive power than the decision tree (DT) and random forest (RF). Furthermore, we identified a series of molecular features and pathways that are associated with patient survival and treatment outcomes. Our study provides perspective on building reliable prognostic and therapeutic strategies and further illuminates the molecular mechanisms of SOC.Impact statement

Efficacy and safety of PARP inhibitors for maintenance treatment of ovarian cancer, regardless of BRCA or HRD status: a comprehensive updated meta-analysis

Without taking into account existing biomarkers like genetic mutations (BRCA mutation, Homologous recombination deficiency) with advanced ovarian cancer (OC), the overall survival (OS), progress-free survival (PFS) of the aggregate all groups that have been classified were hazard ratio (HR): 0.72, 95% confidence intervals (CI): 0.66-0.79 and HR: 0.48, 95%CI: 0.44-0.52, respectively. Meanwhile, the OS and PFS of the whole population (regardless of existing genetic mutation markers) were HR: 0.74, 95%CI: 0.64-0.87 and HR: 0.52, 95%CI: 0.42-0.65, separately. Furthermore, the OS and PFS of positive gene mutation markers were HR: 0.71, 95%CI: 0.61-0.83 (HRD and BRACm) and HR: 0.47, 95%CI: 0.42-0.52 (HRD and BRACm), individually. The poly ADP-ribose polymers (PARP) inhibitors have desired efficiency and security in the maintenance treatment of advanced OC patients with BRCAm or BRCAwt, HRD or HRP and unknown gene status.

Effect of lncRNA LINC00324 on cervical cancer progression through down-regulation of miR-195-5p

Long non-coding RNAs (lncRNAs) have been widely used in the exploration of diseases in recent years. This paper introduced the significance of lncRNA LINC00324 (LINC00324) on the progression of cervical cancer and explored the mechanism of action and potential prognosis of LINC00324. The cervical cancer tissues and adjacent normal tissues of 120 people were collected as research samples. The expression level of LINC00324 was assessed by RT-qPCR, as was miR-195-5p. Knockdown of LINC00324 on the proliferation ability of cervical cancer cells was determined with the help of cell counting kit-8 (CCK-8), and the number of cell migration and invasion was detected by the Transwell method. Luciferase reporter gene assay was used to analyse the correlation of LINC00324 and miR-195-5p. Kaplan-Meier survival curves and multivariate Cox analysis explained the potential prognostic significance of LINC00324 in cervical cancer. Significantly increased expression of LINC00324 and down-regulated miR-195-5p were negatively correlated in cervical cancer. Knockdown of LINC00324 inhibited the progression of cervical cancer, which was related to its mechanism of targeting and downregulating miR-195-5p. In addition, low expression of LINC00324 may prolong the survival period of patients with cervical cancer. LINC00324 targets miR-195-5p to regulate the progression of cervical cancer and have potential as a prognostic molecular marker for cervical cancer.

KLF2 transcription suppresses endometrial cancer cell proliferation, invasion, and migration through the inhibition of NPM1

Endometrial cancer (EC) is the most common gynaecologic malignancy. This study was to explore the role of kruppel-like factor 2 (KLF2) in EC cell behaviours. The expression of KLF2 in EC and its correlation with NPM1 were first predicted on the database. Levels of KLF2 and nucleophosmin 1 (NPM1) in EC cell lines were then determined. After transfection of the overexpression vector of KLF2 or NPM1, cell proliferation, invasion, and migration were evaluated. The binding relationship between KLF2 and the NPM1 promoter was analysed. KLF2 was downregulated while NPM1 was upregulated in EC cells. KLF2 overexpression reduced the proliferation potential of EC cells and the number of invaded and migrated cells. KLF2 was enriched in the NPM1 promoter and inhibited NPM1 transcriptional level. NPM1 overexpression neutralised the effects of KLF2 overexpression on suppressing EC cell growth. Collectively, KLF2 was decreased in EC cells and KLF2 overexpression increased the binding to the NPM1 promoter to inhibit NPM1 transcription, thus suppressing EC cell growth.

Identification of a prognostic model based on immune and hypoxia-related gene expressions in cervical cancer

Tumour immune microenvironment (TIME) has long been a key direction of tumour research. Understanding the occurrence, metastasis and other processes of cervical cancer (CC) is of great significance in the diagnosis and prognosis of tumours. Here, this study applied the univariate Cox regression model to determine the prognostic association of immune and hypoxia signature genes in CC, and used Least Absolute Shrinkage and Selection Operator (LASSO) Cox method to build immune and hypoxia related risk score model to uncover the immune signature of the TIME of CC. Moreover, we used Through the LASSO Cox regression model, we obtained 12 characteristic genes associated with the prognosis of CC, and also associated with immunity and hypoxia. Interestingly, the high-risk group had the properties of high hypoxia and low immunity, while the low-risk group had the properties of low hypoxia and high immunity. In the low-risk group, patients lived longer and had a significant therapeutic advantage of anti-PD-1 immunotherapy. Established risk scores model can help predict response to anti-PD-1 immunotherapy of CC.

Survival of women with cervical cancer in East Africa: a systematic review and meta-analysis

The prognosis for cervical cancer varies greatly between nations. The disparity in cancer survival rates within nations is largely a result of disparities in public knowledge, the accessibility of cancer services, diagnosis and treatment. The purpose of this systematic review and meta-analysis is to assess the survival rate and associated factors among cervical cancer patients in East Africa. Literature search was carried out using Google scholar, PubMed/Medline, Embase and CINHAL. Covidence, a web-based program, was used to import studies for review process. PRISMA guidelines were followed. A total of 110 abstracts were identified from electronic sources. There were five duplicate articles removed. We looked at 105 papers' abstracts and titles, and we excluded 78 of them because they did not fit our inclusion criteria. We conducted a full-text analysis of the remaining 27 papers, leaving out 14 researches that did not fit our inclusion requirements. For final review, 13 studies were included. Using the Joanna Briggs Institute (JBI) assessment checklist, methodological quality was evaluated. The included articles were cohort studies. They were conducted in Ethiopia, Uganda, Zimbabwe, Kenya, Sudan, Tanzania and Rwanda. One-year, two-year, three-year, four-year and five-year overall survival rates ranged from 67% to 92%, 55% to 84%, 44% to 53%, 32% to 47%, and 26% to 43%, respectively. The pooled one-year, two-year, three-year, four-year and five-year survival rates of cervical cancer patients in East Africa were 84%, 71%, 50%, 39% and 36%, respectively. HIV status, late presentation, treatment modalities, older age and presence of comorbidities were the most commonly mentioned prognostic factors for survival. CRD42023402551.

Radiotherapy for postoperative vaginal recurrences of cervical squamous cell carcinoma: analysis of dosing and prognosis

Squamous cell carcinoma (SCC) is the most common type of vaginal recurrence in cervical cancer patients, and the role of salvage radiotherapy on these patients remains unclear. This study aimed to investigate the efficacy of salvage radiotherapy for vaginal recurrence of SCC in patients who previously underwent surgery and to explore prognostic factors associated with survival. Ninety-seven patients with histologically proven SCC who were treated for vaginal recurrence at Peking Union Medical College Hospital were identified. All patients had previously undergone surgery and received salvage radiotherapy. Factors predictive of overall survival (OS), progression-free survival (PFS), and local control (LC) were investigated. The median follow-up time was 42.5 months. The estimated 5-year OS, PFS, and LC rates were 84%, 79%, and 91%. On multivariate analysis, inguinal lymph node metastasis was significantly associated with poor OS; a tumour size ≤4 cm was associated with longer PFS (

Radiation-induced lymphopenia and the survival of women with cervical cancer: a meta-analysis

The current systematic analysis and meta-analysis was aimed to evaluate the association between radiation-induced lymphopenia (RIL) and survival of women with cervical cancer (CC). PubMed, Embase, Web of Science, and Cochrane Library were searched for relevant cohort studies comparing survival between women with CC who developed versus not developed RIL after radiotherapy. We pooled the results using a random-effects model that incorporates heterogeneity. In the meta-analysis, 952 women with CC were included from eight cohort studies. Overall, 378 (39.7%) of them had RIL after radiotherapy. During a median follow-up duration of 41.8 months, pooled results showed that RIL was independently associated with poor overall survival (hazard ratio [HR]: 2.67, 95% confidence interval [CI]: 1.81 to 3.94,

Using robotic single-port vNOTES for gynaecological oncology: omentectomy in a patient with an ovarian granulosa cell tumor—a case study

Robotic single-port transvaginal natural orifice transluminal endoscopic surgery (RSP-vNOTES) is an emerging minimally invasive approach that combines the advantages of robotic surgery with scarless transvaginal access. Its application in gynecologic oncology remains limited, particularly for omentectomy during ovarian cancer staging. We present the case of a 45-year-old woman with an ovarian granulosa cell tumor (GCT) who underwent supplemental staging surgery following unilateral oophorectomy. Using a single-port robotic system via the transvaginal route, hysterectomy, right salpingo-oophorectomy, and omentectomy were performed. Key technical steps included enhanced visualization with gauze placement and use of an additional robotic arm for omental traction. The procedure lasted 2 hours and 10 minutes with an estimated blood loss of 50 mL. No intraoperative or postoperative complications occurred. The patient did not require postoperative analgesics and was discharged on postoperative day 3. Final pathology confirmed absence of omental metastasis. This case demonstrates the feasibility and safety of RSP-vNOTES for omentectomy in gynecologic oncology. The technique offers potential benefits including reduced abdominal trauma, faster recovery, and superior visualization for complex dissections. While further studies are necessary to validate long-term oncologic outcomes, RSP-vNOTES may represent a promising minimally invasive option for selected patients requiring ovarian cancer staging surgery.

Effects of MFG-E8 expression on the biological characteristics of ovarian cancer cells via the AKT/mTOR/S6K signalling pathway

In this study, we assessed the effects of MFG-E8 on the biological characteristics of ovarian cancer cells and explored the underlying mechanisms. Human ovarian cancer SKOV3 cells were transfected with

Efficacy and safety of olaparib in advanced ovarian cancer: a meta-analysis

This study aimed to evaluate the efficacy and safety of olaparib for the treatment of advanced ovarian cancer. All studies that assessed the efficacy and safety of olaparib in advanced ovarian cancer were searched in PubMed, Embase, and Web of Science from their inception to 20 September 2022. The analysis included six studies and 2016 patients. Olaparib could significantly prolong the progression-free survival (PFS) of patients compared to that of the control group (HR = 0.49, 95% CI = 0.36 - 0.68). However, no statistically significant differences were detected in overall survival (OS) and objective response rate (ORR) between the olaparib and control groups. Olaparib treatment increased the number of grade ≥3 adverse events (AEs) in patients with advanced ovarian cancer compared with that in the control group. Olaparib significantly prolonged PFS in patients with advanced ovarian cancer; however, no statistically significant differences were detected in OS and ORR. In terms of safety, olaparib has manageable adverse effects.

Preoperative clinical characteristics for differentiating malignant transformation from torsion of mature cystic teratoma

This retrospective study was conducted in 27 patients with malignant transformation of mature cystic teratoma（MT-MCT）and 125 ovarian teratoma patients with torsion who underwent surgery in the First Affiliated Hospital of Wenzhou Medical University from 2008 to 2019. The incidence of MT-MCT in this study was 0.79%. The 3-year overall survival (OS) rate was 69.6 ± 9.6%. The 3-year progression-free survival (PFS) rate was 58.3 ± 9.6%. Kaplan-Meier survival analysis indicated that patients with squamous cell carcinoma (SCC) had significantly shorter OS compared with non-SCC patients. Older age (OR 1.076, 95% CI 1.041-1.111), higher platelet (PLT) level (OR 1.012, 95% CI 1.005-1.020) and lower neutrophil-to-lymphocyte ratio (NLR) level (OR 0.794, 95% CI 0.647-0.915) were independent predictors of MT-MCT. The area under the curve (AUC) for the combined use of age, PLT count and NLR was 0.921 (95% confidence interval 0.877-0.964;

Analysis of prognostic factors for cervical mucinous adenocarcinoma and establishment and validation a nomogram: a SEER-based study

Up to now, there are no relevant studies on prognostic factors of cervical mucinous adenocarcinoma. Therefore, we explored the prognostic factors for cervical mucinous adenocarcinoma, and established and validated the prognostic model using the SEER database. We selected the independent factors through univariate and multivariate analyses. LASSO regression analysis was conducted to identify potential risk factors. In conjunction with LASSO and multivariate analysis, the nomogram incorporated three variables, including age, tumour size, and AJCC stage for OS. The c-index was 0.794 and 0.831 in development and validated cohorts, indicating that this prediction model showed adequate discriminative ability in the development cohort. Besides, calibration curves showed good concordance for the development cohort, as well as the validation cohort. We constructed a first-of-its-kind nomogram to predict cervical mucinous adenocarcinomas OS and it showed better performance than AJCC and FIGO stages. Patients with cervical mucinous adenocarcinoma might benefit from using this model to develop tailored treatments.IMPACT STATEMENT

EIF3D promoted cervical carcinoma through Warburg effect by interacting with GRP78

The incidence of cervical cancer ranks third among all female tumours globally and second in developing countries. However, the role of eukaryotic translation initiation factor 3 subunit D (EIF3D) in cervical carcinoma is unknown. This study investigated the effects of EIF3D on cell progression of cervical carcinoma and its underlying mechanism

Effects of vaginal dilation therapy on vaginal length, vaginal stenosis, vaginal elasticity and sexual function of cervical cancer survivors

Cervical cancer survivors can experience vaginal length shortening, vaginal stenosis, vaginal elasticity deterioration, sexual frequency reduction and sexual dysfunction. This prospective, uncontrolled, monocentric clinical interventional study aimed to evaluate the effect of vaginal dilation therapy on vaginal condition and sexual function of cervical cancer survivors who had not received timely vaginal dilation. A total of 139 patients completed the study. They received 6 months of vaginal dilation therapy. We evaluated their vaginal elasticity, vaginal diameter, vaginal length and sexual function before and after vaginal dilation therapy. Their vaginal conditions were evaluated by customised vaginal moulds, and the sexual function was assessed by female sexual function index. The SPSS 25 software was used to analyse all the data. Age, vaginal diameter and sexual intercourse frequency before diagnosis were significantly associated with female sexual dysfunction of the patients after cancer treatment. Vaginal dilation therapy improved vaginal stenosis, vaginal length and sexual function in all the patients; however, the vaginal elasticity and incidence of sexual dysfunction did not improve significantly. Sexual intercourse frequency before diagnosis, vaginal elasticity, time interval from last treatment and treatment modalities were significantly associated with the change in female sexual function index score before and after vaginal dilation therapy. Patients with a time interval from the last treatment less than 24 months or those who had moderate or good vaginal elasticity, benefitted more from vaginal dilatation therapy. Cervical cancer survivors who had not received timely vaginal dilation still benefitted from vaginal dilation therapy, irrespective of the treatment methods they received. Moreover, vaginal dilation therapy should be performed as early as possible after cervical cancer treatment.

The inflammatory markers combined with CA125 may predict postoperative survival in endometrial cancer

Endometrial cancer (EC) has a high latency, making prognosis difficult to predict. Cancer antigen 125 (CA125) is not specific as a tumour marker for EC; however, complete blood count (CBC) inflammatory markers are associated with prognosis in various malignancies. Thus, this study investigated the value of CBC inflammatory markers combined with CA125 levels in predicting the prognosis of patients with EC. In this study, 517 patients with EC were recruited between January 2015 and January 2022, and clinical characteristics, CBC inflammatory markers, and CA125 levels were assessed. Differences in each index at different EC stages and the correlation between the index and EC stage were analysed, and the influence of the index on EC prognosis was evaluated. Platelet distribution width (PDW) levels were significantly lower in patients with advanced EC than in those with early EC, whereas the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and CA125 levels were significantly higher in patients with advanced EC (all P < 0.05). ROC curve and multivariate logistic regression analyses indicated that decreased PDW and increased CA125 levels were independent risk factors for EC staging progression. In addition, multivariate Cox regression analysis showed that the combination of low PDW and high CA125 (PDW + CA125 = 2) was an independent prognostic factor of survival in EC patients. Kaplan-Meier survival analysis indicated that patients with low PDW and high CA125 had worse overall survival. The PDW and CA125 score may be an independent prognostic factor for postoperative overall survival in patients with EC and a useful marker for predicting the prognosis of these patients.

DNA methylation triage of human papillomavirus-positive atypical squamous cells of undetermined significance in cervical cancer screening

Triage of human papillomavirus (HPV)-positive women with atypical squamous cells of undetermined significance (ASC-US) remains a longstanding clinical challenge in cervical cancer screening, as conventional strategies often lead to excessive colposcopy referrals. We conducted a diagnostic cohort study of 195 HPV-positive women who underwent ASC-US cytology. Multigene DNA methylation analysis was performed on residual cervical exfoliated cells, using histology from colposcopy-directed biopsy and/or endocervical sampling as the reference standard to minimise colposcopy referrals. Our results showed that methylation levels of PAX1, EPB41L3, and FAM19A4 increased progressively from ≤ CIN1 to CIN2, CIN3, and cervical cancer, with significant decreases in ΔCt values from ≤ CIN1 to CIN3 for all three genes ( The host multigene DNA methylation assay demonstrates high specificity and good sensitivity for triaging HPV-positive ASC-US women, with the potential to reduce colposcopy referrals while maintaining robust detection of high-grade lesions, particularly in those aged ≥30 years.

Effect of ubiquitin-specific proteinase 43 on ovarian serous adenocarcinoma and its clinical significance

Ovarian cancer stands as a highly aggressive malignancy. The core aim of this investigation is to uncover genes pivotal to the progression and prognosis of ovarian cancer, while delving deep into the intricate mechanisms that govern their impact. The study entailed the retrieval of RNA-seq data and survival data from the XENA database. Outliers were meticulously excluded in accordance with TCGA guidelines and through principal components analysis. The R package 'deseq2' was harnessed to extract differentially expressed genes. WGCNA was employed to prioritise these genes, and Cox regression analysis and survival analysis based on disease-specific time were conducted to identify significant genes. Immunohistochemistry validation was undertaken to confirm the distinct expression of USP43. Furthermore, the influence of USP43 on the biological functions of ovarian cancer cells was explored using techniques such as RNA interference, western blotting, scratch assays, and matrigel invasion assays. The examination of immune infiltration was facilitated via CIBERSORT. The study unearthed 5195 differentially expressed genes between ovarian cancer and normal tissue, comprising 3416 up-regulated and 1779 down-regulated genes. WGCNA pinpointed 204 genes most intimately tied to tumorigenesis. The previously undisclosed gene USP43 exhibited heightened expression in tumour tissues and exhibited associations with overall survival and disease-specific survival. USP43 emerged as a driver of cell migration (43.27 ± 3.91% vs 19.69 ± 1.94%) and invasion ability (314 ± 32 vs 131 ± 12) through the mechanism of epithelial mesenchymal transition, potentially mediated by the KRAS pathway. USP43 was also identified as a booster of CD4+ T memory resting cell infiltration, while concurrently reducing M1 macrophages within cancer, thereby fostering a milieu with relatively immune suppressive traits. Interestingly, USP43 demonstrated connections with epigenetically regulated-mRNAsi, although not with mRNAsi. This study underscores the role of USP43 in facilitating tumour migration and invasion. It postulates USP43 as a novel therapeutic target for ovarian cancer treatment.

The prognostic value of squamous differentiation in endometrioid type endometrial cancer: a matched analysis

We aimed to examine the effect of the squamous differentiation on survival outcomes of women with endometrioid adenocarcinoma. We retrospectively reviewed the patients with endometrioid adenocarcinoma who underwent primary surgical treatment in a tertiary referral hospital. Sixty-nine patients having squamous differentiation constituted the case group. Each woman in the case group was matched with two patients in the control group based on age, disease stage, tumour grade, lymphovascular space invasion, tumour size, myometrial invasion, type of surgery and adjuvant therapy. During the follow-up, the recurrence rates were similar between the case (5/69, 7.2%) and control (10/138, 7.2%) groups (

The objective of this study was to examine the rate of and indications for readmission in patients with advanced staged ovarian cancer undergoing rectosigmoid resection and primary anastomosis, an important quality metric. A retrospective review was conducted of patients with primary ovarian cancer who underwent rectosigmoid resection as part of cytoreductive surgery between July 2003 and July 2014. Univariate analysis identified rates and predictors of readmission. Fifty patients were eligible for analysis. The unanticipated 30-day readmission rate was 18% (

Ever-use of the intra-uterine device and the risk of ovarian cancer

The association between the use of the intra-uterine device (IUD) and the risk of ovarian cancer is not well known. In this study, we sought to determine whether the use of an IUD is associated with a reduction in the risk of ovarian cancer. We searched Medline, EMBASE, Google Scholar, Scopus, ISI Web of Science and Cochrane database search, as well as PubMed (www.pubmed.gov) and RCT registry (www.clinicaltrials.gov) until the end of June 2019 to conduct a systematic review and meta-analysis comparing ever-use vs. never-use of an IUD and the risk of subsequent ovarian cancer. We obtained 431 records, of which 9 met inclusion criteria. A total of five case-control studies and four cohort studies were retrieved to establish the risk of ovarian cancer amongst ever-users of an IUD. Relative to the never-use of the IUD, ever-use conferred a lower risk of ovarian cancer with an estimated OR of 0.67 95% CI [0.60 - 0.74],

Nicotinamide N-methyltransferase overexpression may be associated with poor prognosis in ovarian cancer

Ovarian cancer is the fifth leading cause of cancer-related mortality in women. Nicotinamide N-methyltransferase (NNMT) is a metabolic enzyme and there is growing evidence to suggest that it plays an important role in cancer progression. This is the first study to examine the expression of NNMT in serous ovarian cystadenomas, serous borderline tumours, low grade serous carcinomas (LGSC) and high grade serous carcinomas (HGSC) and investigate the potential independent association of NNMT expression with survival. Tissue samples were analysed immunohistochemically for NNMT expression. The stromal NNMT score was significantly higher in HGSC compared to serous cystadenomas and serous borderline tumours (

cDNA expression library screening revealed novel functional genes involved in clear cell carcinogenesis of the ovary in vitro

In order to identify genes involved in the pathogenesis of clear cell carcinoma of the ovary (CCC), functional screening using a cDNA expression library was performed. We extracted mRNA from a CCC cell line (RMG-1), established a cDNA library using a retroviral vector, transfected that library into mouse NIH3T3 cells and sequenced the resultant foci. The tissue-type specific expression of isolated genes and their transforming activities were evaluated. Seven genes were isolated. Of these genes, the mRNA expression of SEC61B and DVL1 is significantly stronger in CCC than in other histological types (

Does sites of recurrence impact survival in secondary cytoreduction surgery for recurrent epithelial ovarian cancer?

Outcomes of secondary cytoreduction surgery (SCS) were evaluated for morbidity, progression free survival (PFS) and overall survival (OS) and factors influencing results were explored. Retrospective analysis of all cases of SCS for epithelial ovarian cancer (EOC) was performed from October 2010 to December 2017. 62 patients were prospectively identified as candidates for SCS and 57 underwent SCS. 20(35%) patients required bowel resection/s, 24(42%) had nodal resections and 11(19%) had extensive upper abdominal surgery. 51(89%) achieved complete cytoreduction. After a median follow-up of 30 months (range 9-95 months), median PFS was 32 months (CI 17-76 months) and median OS has not reached. Seventeen patients have died and 32 have progressed. Three patients had Clavien-Dindo grade-3 and two had grade-4 morbidity. Patients who had multi-site recurrence had shorter median PFS (

Changing patterns of referral into a family history clinic and detection of ovarian cancer: a retrospective 10-year review

This study examines whether a change in the criteria for genetic testing for ovarian cancer risk changed the nature of referrals into our Familial Cancer service. This is a retrospective review of 273 women who underwent risk reducing surgery (RRS). The primary outcome was to establish whether there was an increase in women having RRS with a confirmed genetic mutation. Secondary outcomes included the incidence of occult cancer and of subsequent primary peritoneal cancer. The results showed an increase in women being offered RRS based on genetic diagnosis; 91% versus 32% before the criteria change. Four occult malignancies (1.5%) and two peritoneal cancers (0.7%) were noted.We have demonstrated a change in the nature of referrals to the familial cancer service from perceived risk to genetic diagnosis. We can now counsel women more accurately. With a defined risk we are enabling them to make an informed decision regarding risk reduction.

The effects of REG4 expression on chemoresistance of ovarian cancer

UK national survey of the management of vaginal intraepithelial neoplasia

Vaginal intraepithelial neoplasia (VaIN) is less common than intraepithelial neoplasia at other non-cervical sites and can be challenging to manage. This survey describes current clinical practice by colposcopists in the UK. An online questionnaire was emailed to all the lead colposcopists in U.K. A total of 86 (43%) responses were obtained. The median number of cases of VaIN seen in a year was five (range 0-100. Most clinics (95%) managed low grade VaIN conservatively. Local vaginal mucosal excision was the most common surgical procedure. Half of respondents adopted observation, although 64% of the units referred cases to a cancer centre. More than half used a combination of cytology and colposcopy for follow-up; only two reported using Human papilloma virus testing. Seventy-seven of eighty-six lead colposcopists did not have a local guideline and would support national guidance. Treatment differed across the UK with no agreed management guidelines.Impact statement

The evolution of mature cystic teratomas of the ovary into squamous cell carcinoma: two case reports and review of the literature

Mature Cystic Teratomas (MCT) of the ovary or Dermoid Cysts are common benign tumours found in 10-20% of women. However, 0.2-2% of those cysts underwent malignant transformation. Squamous Cell Carcinoma (SCC) is the most frequent histological type reported in the literature.As 2021, there are limited reports of malignant tumours arising from MCT with no guidelines related to the management of these atypical cases. Herein, we describe two cases of MCT that evolved into SCC with different stages and prognosis and we review the current literature to date highlighting the potential risk of malignant transformation of these considered benign cysts and the need for strong evidence protocols for staging and treatment of this atypical entity.IMPACT STATEMENT

The expression of p16 and galectin-3 in cervical intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC) uterine cervix

Cervical cancer is the most prevalent cancer among women in India. The main cause of cervical cancer is persistent human papilloma viral (HPV) infection. HPV inactivates the pRb tumour suppressor protein; thus p16 expression, which is controlled by a negative feedback mechanism, is relatively increased. Galectin-3 is directly and indirectly connected to cancer cell activity and contributes to oncogenesis, angiogenesis, cancer progression and metastasis. Thus, the aim of this study was to study the expression of p16 and galectin-3 in Cervical Intraepithelial Neoplasia (CIN) and Squamous Cell Carcinoma (SCC) and to correlate p16 and galectin-3 expression. On hundred and eighteen newly-diagnosed untreated cases of CIN and SCC of uterine cervix were included in the study. Expression of p16 and galectin 3 was more pronounced in invasive SCC and High-grade Intraepithelial Lesion (HSIL), as compared to Low-grade Intraepithelial Lesion (LSIL).Thus, it may be used in clinical setting to monitor cervical lesions and to predict their progression.Impact statement

Intrauterine device migration into the bladder with stone formation after radiochemotherapy for cervical cancer: a case report

Human papillomavirus and cervical cancer

Cervical cancer is by far the most common HPV-related disease. About 99.7% of cervical cancer cases are caused by persistent genital high-risk human papillomavirus (HPV) infection. Worldwide, cervical cancer is one of the most common cancers in women with an estimated 528,000 new cases reported in 2012. Most HPV infections clear spontaneously but persistent infection with the oncogenic or high-risk types may cause cancer of the oropharynx and anogenital regions. The virus usually infects the mucocutaneous epithelium and produces viral particles in matured epithelial cells and then causes a disruption in normal cell-cycle control and the promotion of uncontrolled cell division leading to the accumulation of genetic damage. There are currently two effective prophylactic vaccines against HPV infection, and these comprise of HPV types 16 and 18, and HPV types 6, 11, 16 and 18 virus-like particles. HPV testing in the secondary prevention of cervical cancer is clinically valuable in triaging low-grade cytological abnormalities and is also more sensitive than cytology as a primary screening. If these prevention strategies can be implemented in both developed and developing countries, many thousands of lives could be saved.

Doctor and patient awareness of treatment options for cervical intraepithelial neoplasia 1 (CIN 1): a survey questionnaire approach

The purpose of this study was to investigate doctors' and patients' perceptions of cervical intraepithelial neoplasia 1 (CIN 1) and its treatment methods. A survey questionnaire was offered to obstetrics and gynaecology doctors and patients with CIN 1 in 2017. Only 43% of patients knew of this disease. Regarding perceptions of its aetiology, 64% of the patients perceived human papillomavirus infection to be the main cause of CIN 1. Patients' most preferred treatments were medication (20%), followed by alternative treatment (14%). Among doctors, regular follow-up was the most preferred method for managing CIN 1. The survey showed that current treatment modalities for CIN 1 were satisfactory to only half of doctors (50%) and patients (53%). Overall, 70% of doctors responded that new drug development for CIN 1 is needed. Although, CIN 1 is a low-grade lesion, doctors and patients expressed the desire for new therapeutic agents to manage it.IMPACT STATEMENT

Jordanian women’s attitudes towards cervical cancer screening: has the pattern changed?

The objective of this study was to report the current Jordanian rate of cervical smear test uptake, and study changes in women's attitude to the smear test since the last published report in 2002. A prospective cross-sectional study of Jordanian women who at the time of the study were living in Jordan. The study period was from December 1 2018 to December 31 2018. Six hundred and twelve women were recruited, and the mean age was 36 years. Thirty-eight percent of the women in the study said they had had a smear test before. Of those who had ever had a test, 88% did so as a routine test. Of women who had never had a smear test, 61% said they had heard about the test, 50% of them did not give a 'logical' reason for not having a test. While the current rate is less than in 2002, more women recognised the test as being important. While the rate of cervical smear test uptake in Jordan remained low (38%), it is better than the rate in 2002 of 25.5%. Severe deficiencies in the knowledge of the test exist. Implementing a national cervical screening programme supported by media-led health education and promotion is likely to increase the test uptake and reduce incidence of cervical cancer.Impact statement

Prevalence of prescribing topical corticosteroids to patients with lichen sclerosus following surgery for vulvar cancer: a survey among gynaecologic oncologists in The Netherlands

Vulvar lichen sclerosus (LS) is a chronic inflammatory dermatosis which can progress to precursor lesion differentiated vulvar intraepithelial neoplasia (dVIN) and vulvar squamous cell carcinoma (VSCC). The risk of developing recurrent vulvar cancer following LS-associated VSCC is high. Evidence suggests that treatment of LS with topical corticosteroids (TCS) can prevent progression to dVIN, VSCC and recurrences. However, current guidelines do not give any recommendation on the management of LS following surgery for VSCC. The aim of this study was to conduct a survey among all registered gynaecologic oncologists (GOs) in the Netherlands to evaluate the current management of LS patients without a history of VSCC (LS An online survey was distributed to all registered GOs in the Netherlands. Primary outcome measures were the frequency, type and duration of TCS treatment prescribed for LS Forty-four GOs completed the survey, resulting in a response rate of 75%. TCS were prescribed more often to patients with LS The majority of GOs who participated in our study endorse the utilisation of long-term ultra-potent TCS therapy in both patients with LS

Characteristics of recent clinical investigations into systemic therapy against cervical cancer: systematic analysis of trial details from Clinicaltrials.gov

A review that systematically assessed the current state of clinical research into systematic therapy-based interventions against invasive cervical cancer. It analysed registry details of 59 systemic therapy-based cervical cancer trials on ClinicalTrials.gov with study start dates between January 2010 and June 2018. The review characterised the present cervical cancer trial landscape in terms of trial design features, systemic therapy (chemotherapy, targeted therapy, immunotherapy, and repurposed therapy), and disease stages of interest. It also made an attempt to qualitatively synthesise the trial landscape in terms of the nature and trend of research focus, alignment with existing clinical needs, novelty of treatments or concepts pursued, and promise of new treatments.

Septin9 DNA methylation as a promising biomarker for cervical cancer

Aberrant Septin9 methylation in cervical cancer has been rarely studied. We aimed to identify its diagnostic value in cervical cancer using cervical scrapings, and its predictive potential in plasma for pelvic nodal metastasis of cervical cancer. The statuses of methylated Septin9 in fresh cervical lesions and cervical scrapings were first evaluated by using quantitative methylation-specific PCR. Subsequently, the relationship between Septin9 methylation in 113 plasma samples and pelvic nodal metastasis of cervical cancer was evaluated. Methylated Septin9 was detected in all cancerous tissues, but not in cervicitis. The degrees of Septin9 methylation increased with growing severity of cervical lesions in cervical scrapings. The sensitivity of methylated Septin9 was lower than that of cytology, while it yielded a high specificity and area under the curve in detecting high-grade squamous intraepithelial lesion or cervical cancer; and when Septin9 methylation combined with HPV16/18 genotyping, the sensitivity would increase from 70.42% to 82.39%. Plasma-based Septin9 methylation had a high discriminatory power in predicting pelvic nodal metastasis of cervical cancer, with an optimal specificity of 81.48%. In conclusion, we demonstrated methylated Septin9 to be an innovative diagnostic biomarker for cervical cancer and its non-invasive predictive potential in plasma for pelvic nodal metastasis of cervical cancer.Impact statement

Knockdown of S100A2 inhibits the aggressiveness of endometrial cancer by activating STING pathway

Endometrial cancer is a kind of gynaecological cancer. S100A2 is a newfound biomarker to diagnose endometrial cancer. This study was to investigate the role of S100A2 on regulating migration and invasion of endometrial cancer. The mRNA and protein levels of S100A2 were obtained by quantitative real-time polymerase chain reaction, immunohistochemistry and western blot methods. Cell viability was measured by the Cell Counting Kit-8 assay. Cell migration and invasion were quantified using transwell assays. Western blot assay was conducted to quantify protein expressions of epithelial to mesenchymal transition-related proteins (N-cadherin and E-cadherin). Furthermore, S100A2 was significantly up-regulated in endometrial cancer tissues. Knockdown of S100A2 inhibited cell viability, migration and invasion of endometrial cancer cells. Meanwhile, STING pathway was activated by the inhibited S100A2. STING inhibitor C-176 significantly reversed the effects of S100A2 knockdown on aggressive behaviours of endometrial cancer cells. Inhibition of S100A2 dramatically suppresses the tumour growth S100A2 functions as an oncogene in endometrial cancer. Targeting S100A2 may be a promising therapeutic method to treat endometrial carcinoma.

Rac3 promotes proliferation and invasion of endometrial cancer through the AKT/mTOR signalling pathway

Rac3 is associated with the malignancy of various tumours, including endometrial cancer (EC). Silencing Rac3 has been shown to effectively enhance the sensitivity of EC cells to chemotherapeutic drugs. Nonetheless, the underlying mechanism is still unclear. Firstly, the association between Rac3 and EC was verified through the TCGA database. Subsequently, Ishikawa cell lines with Rac3 knockdown were constructed. The effects of Rac3 knockdown on the growth, migration and invasion of Ishikawa cells were assessed through clone formation experiments, CCK-8 experiments, flow cytometry, and Transwell experiments. Finally, qRT-PCR and WB experiments were conducted to initially explore the potential mechanism of action of Rac3 in the development of EC. Compared with normal tissues, the expression of Rac3 in EC tissues was significantly elevated, and this expression further increased with the aggravation of tumour. In Ishikawa cells with Rac3 knockdown, cell viability was significantly reduced, the apoptosis rate increased, and the invasion and migration abilities of the cells were inhibited. Correlation analysis of EC samples revealed a positive correlation between Rac3 and AKT2, AKT3 and mTOR. Additionally, WB and qRT-PCR also suggested that the mechanism of action of Rac3 in the development of EC may be related to the upregulation of AKT2, AKT3 and mTOR. Knockdown of Rac3 may inhibit the occurrence and development of EC, which is related to its inhibition of AKT2, AKT3 and mTOR. This discovery provides a theoretical basis for clinical screening of biomarkers for EC and the development of potential therapeutic targets.

Role of hysteroscopy during conservative management of atypical endometrial hyperplasia and early-stage endometrial cancer in patients who desire pregnancy

Twenty-five percent of cases of endometrial cancer appear in women with unfulfilled reproductive desires

Does the character of the hospital of primary management influence outcomes in patients treated for presumed early stage endometrial cancer and atypical endometrial hyperplasia: a comparison of outcomes from a cancer unit and cancer centre

A retrospective study from 2015 to 2020 comparing overall survival (OS) outcomes of a cancer unit and centre for presumed early stage endometrial cancers is presented. Cancer centres manage these presumed early endometrial cancer (EC) in situations of complex co-morbidities, surgical challenges as well as their own local unit patients. Our analysis compares 138 patients at KMH (unit) and 282 patients at RDH (centre) on OS, patient demographics, grading histology and final histology. Patients with presumed early stage EC can be reassured regarding no difference in OS between the cancer unit and centre management (

Sociodemographic predictors of endometrial cancer mortality in South Africa (1997 to 2015): a case-control study

South Africa is currently undergoing epidemiological and health transition that may impact on the risk factors of endometrial cancer mortality. We evaluated the sociodemographic characteristics of women that died from endometrial cancer in South Africa from 1997 to 2015.An unmatched case control study was conducted to compare the sociodemographic characteristic of women that died from endometrial cancer cases (

A functional polymorphism in the poly(ADP-ribose) polymerase-1 gene increases the risk of endometrial carcinoma

The aim of this study was to investigate the effects of two functional genetic polymorphisms in the poly(ADP-ribose) polymerase-1 (

Characteristics and clinicopathological features of patients with ovarian metastasis of endometrial cancer: a retrospective study

There are no criteria for patient selection for ovarian-preserving surgery for endometrial cancer (EC). In this study, intraoperative findings of ovarian swelling (OvS) and the clinicopathological features of patients with EC with or without ovarian metastasis were analysed to identify risk factors for ovarian metastasis. Patients who underwent surgery for EC between 2012 and 2019 at our hospital were enrolled. In univariate analysis, all features were significantly higher in metastasis(+) cases. In multivariate analysis, lymphatic space invasion (LSI), cervical stromal involvement (CSI), peritoneal dissemination, and OvS were significant risk factors. In univariate analysis in stage I and II cases classified without adnexal pathological factors, type 2 histologic type, LSI, CSI, and OvS were significantly higher in metastasis(+) cases. LSI, CSI, and OvS were significant risk factors in multivariate analysis. Patients with type 1 histologic type EC without myometrial invasion ≥1/2, CSI and extrauterine lesions are appropriate for ovarian preservation. IMPACT STATEMENT

Human leukocyte antigen-G (HLA-G) expression plays an important role in the diagnosis and grading of endometrial cancer

The research aimed to investigate the expression of human leukocyte antigen G (HLA-G) in cancer tissues and normal endometrium and the expression of HLA-G in the three different grades of Endometrial cancer, to determine if HLA-G expression is related with the diagnosis and grading of endometrial cancer. The expression of HLA-G protein was analysed in the primary tumour in 97 tissue samples obtained from endometrial cancer, in which 30 samples were at pathological Grade 1; 37 samples were at Grade 2; 27 samples were at Grade 3; and the other 5 samples were obtained from normal endometrium. The HLA-G protein level was measured by immunohistochemical method and analysed according to the clinicopathological parameters of patients. A statistically significant difference (

Prognostic significance of positive peritoneal cytology in endometrial cancer patients

Although peritoneal cytology has been shown to be an independant predictor of survival in endometrial cancer, the present international federation of gynaecology and obstetrics (FIGO) staging system does not involve it for risk stratification. This work aimed to assess the prognostic importance of PPC (positive peritoneal cytology) in endometrial cancer patients. The medical profiles of uterine carcinoma patients were reviewed who were referred to Khatam-al- Anbia and Bahman hospital within 2010-2019. The factors possibly affecting peritoneal fluid cytology in all patients were analysed. There was a considerable association between survival and the number of lymph nodes involvement (95% CI = 2.5 - 12.51, OR = 5.59,

The impact of uterine adenomyosis on the histopathological risk factors and survival in patients with endometrial adenocarcinoma

A retrospective cohort study was performed on patients diagnosed with endometrial adenocarcinoma (EC) during a 9-year period to investigate the impact of co-existing adenomyosis on patients with EC. Group A included women with EC and adenomyosis and Group B EC cases without the presence of adenomyosis. Group A was more likely to have early-stage disease, tumours without deep myometrial invasion, low-grade tumours and tumours with negative lymphovascular space invasion when compared to Group B (

Genitourinary syndrome, local oestrogen therapy and endometrial pathology: a single-centre, randomised study

The objective of this study was to assess the endometrial pathology developed (EP) in postmenopausal women with genitourinary syndrome during and after vaginal oestrogen therapy. The 67 patients included were randomly grouped into group I underwent local oestrogen (oestriol) therapy and group II, underwent no therapy. Each patient's medical history was taken and clinical and gynecological examination, with transvaginal ultrasound at the time of inclusion and during the control visits, was done. The study results show no statistically higher risk of EP for vaginal oestrogen therapy of genitourinary syndrome users compared to the non-users in menopause. No one atypical endometrial hyperplasia and endometrial intraepithelial neoplasia case during the study period was found.Impact statement
