Sentinel lymph node biopsy in apparently early-stage epithelial ovarian cancer: a systematic review and meta-analysis

To evaluate the detection rate, sensitivity, and negative predictive value (NPV) of sentinel lymph node (SLN) biopsy in patients with apparently early-stage epithelial ovarian cancer (EOC). A systematic search of multiple electronic databases was conducted from inception to October 31, 2025. Studies reporting detection rate, sensitivity, and NPV of SLN biopsy in apparently early-stage EOC, with completion pelvic and para-aortic lymphadenectomy as reference standard, were included. Study selection, risk-of-bias assessment, and data extraction were independently performed by four reviewers. Pooled estimates with 95 % confidence intervals (CI) were calculated using random-effects models on a per-patient basis and by anatomical site. Heterogeneity was assessed using the I Fourteen studies comprising 365 patients were included. Most studies used indocyanine green injected into the infundibulopelvic ligament for para-aortic mapping and the utero-ovarian ligament for pelvic mapping. The pooled para-aortic detection rate was 79.9 % (95 %CI 66.1-91.4 %; I In apparently early-stage EOC, SLN biopsy shows acceptable para-aortic detection but limited pelvic detection. Nonetheless, sensitivity and NPV indicate high diagnostic accuracy. Further studies are needed to optimize pelvic mapping strategies and confirm these findings. At present, sentinel lymph node mapping in apparently early-stage epithelial ovarian cancer should be regarded as investigational and not as standard of care.

Circulating tumor DNA in the diagnosis of ovarian cancer: a systematic review

Ovarian cancer remains a leading cause of gynecologic cancer mortality worldwide, largely due to late-stage diagnosis and limited early detection tools. Circulating tumor DNA (ctDNA) has emerged as a promising non-invasive biomarker with the potential to improve diagnostic accuracy through detection of tumor-specific genetic and epigenetic alterations. This systematic review aimed to evaluate the diagnostic accuracy of ctDNA in detecting ovarian cancer compared to healthy controls or benign conditions. A comprehensive literature search was conducted across PubMed, Web of Science, and EBSCO databases through April 2024, including studies that assessed sensitivity, specificity of ctDNA assays in plasma or serum samples. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. PROSPERO registration number: CRD42024590089. Nineteen studies met inclusion criteria, employing a variety of molecular techniques including polymerase chain reaction-based methylation assays (73.7%) and sequencing methods (whole genome sequencing/next-generation sequencing) (21%), targeting single genes or multi-gene panels. Diagnostic accuracy of ctDNA varied, with sensitivity (40.6%-94.7%) and specificity (56%-100%) ranging broadly, but often outperforming CA125, particularly in early-stage. Concordance between ctDNA and tumor tissue ranged from moderate (r = 0.428) to strong (r = 0.771). Although heterogeneity across studies precluded meta-analysis, narrative synthesis suggests that ctDNA may offer an improved early detection capability over CA125, through methylation and copy number variation analyses. Further controlled prospective studies are needed to validate the clinical utility of ctDNA as a complementary tool in ovarian cancer detection.

The Relationship Between the Vaginal Microbiota and the Ovarian Cancer Microenvironment: A Journey from Ideas to Insights

Background: The tumor microenvironment offers a new perspective in gynecologic oncology. In ovarian cancer, numerous preclinical studies, especially organoid models, have highlighted cellular, immune, and biochemical mechanisms. Beyond these sophisticated findings, more practical aspects require attention, such as the role of vaginal microbiota, which represents an interplay between external agents and internal genitalia, and its potential profiling role in early detection beyond the promise of microbiota-targeted therapies. Objectives: This review aims to assess whether such a correlation is speculative or scientifically grounded. Methods: A focused literature search was conducted on vaginal microbiota and its correlation with ovarian cancer to define the current state of knowledge. Results: Mixed outcomes have been reported, yet there is a rational and scientific basis supporting further investigation. Clinical approaches increasingly consider vaginal microbiota as relevant. However, we have to say that most available evidence is still preliminary and largely preclinical to set realistic expectations for readers. Although additional studies are needed, emerging insights highlight its importance and practical implications. We present a diagnostic–therapeutic management flowchart summarizing current evidence). Discussion: Most links between the vaginal microbiota and ovarian cancer are correlational rather than causal. The idea that microbes ascend from the vagina to the ovaries is proposed but still definitely not demonstrated. Confounding factors like age, hormones, and BRCA status complicate interpretation, and ovarian cancer itself could secondarily alter the microbiota. Mechanistic studies and longitudinal data are still needed to clarify whether dysbiosis contributes to carcinogenesis or is merely a consequence. As gynecologists, we summarize key aspects and emphasize to colleagues the importance of incorporating these findings into daily clinical practice. Vaginal dysbiosis should be considered not only a local imbalance but also a potential strategy for primary cancer prevention. Conclusions: Future research on the tumor microenvironment and vaginal microbiota will expand scientific knowledge and guide innovative preventive and therapeutic strategies.

Surgical timing in advanced ovarian cancer during the TRUST trial era: A systematic review, meta-analysis and study-level meta-regression of randomized controlled trials

The best surgical timing for advanced epithelial ovarian cancer, whether primary debulking surgery or interval debulking surgery, remains debated. Recent data, including the preliminary ones from TRUST trial, necessitates an updated critical evaluation. A systematic search of PubMed identified only randomized controlled trials comparing interval debulking surgery versus primary debulking surgery in patients with newly diagnosed advanced ovarian cancer. Primary outcomes included overall survival (OS) and progression-free survival (PFS). A random-effects meta-analysis, meta-regression, cumulative synthesis, and leave-one-out influence analysis were performed. A total of 2303 patients were included. Compared to primary debulking surgery, interval debulking surgery was associated with lower rates of postoperative complications (OR = 0.37; 95 % CI: 0.18-0.79; P = 0.01) and mortality (OR = 0.23; 95 % CI: 0.09-0.57; P = 0.002). Meta-analysis showed higher rates of complete cytoreduction with interval debulking surgery (OR = 3.84; 95 % CI: 2.14-6.91; P < 0.00001) and lower rates of macroscopic residual disease (OR = 0.20; 95 % CI: 0.13-0.30; P < 0.00001). Pooled data revealed no significant difference in OS (HR = 0.95; 95 % CI: 0.87-1.04; P = 0.26) or PFS (HR = 0.94; 95 % CI: 0.85-1.03; P = 0.16). Subgroup analyses by stage and residual disease confirmed similar survival outcomes. The meta-regression results suggested that even in trials with very high complete cytoreduction rates, no clinically meaningful OS benefit was observed for upfront surgery. In conclusion, interval debulking surgery offers comparable survival outcomes to primary debulking, with reduced perioperative morbidity and mortality, supporting its role as a valid surgical alternative. PROSPERO REGISTRATION NUMBER: CRD420251105308.

Inflammatory Indices and CA 125: A New Approach to Distinguish Ovarian Carcinoma and Borderline Tumors in Suspicious Ovarian Neoplasms from a Retrospective Observational Multicentric Study

Background and Objectives: This study aimed to evaluate the diagnostic potential of systemic inflammatory indices such as Systemic Inflammation Response Index (SIRI) and Systemic Inflammatory Response (SIR). These were assessed in combination with CA 125 to distinguish ovarian carcinoma (OC) from borderline ovarian tumors (BOT) in patients with suspicious adnexal masses. Materials and Methods: A retrospective multicenter observational study including patients undergoing surgery for suspected ovarian neoplasms was conducted. Inclusion criteria required preoperative blood sampling for inflammatory markers and CA 125. SIR-125 and SIRI-125 were developed by combining SIR and SIRI with CA 125 levels. Diagnostic performance was assessed using ROC curve analysis and linear regression models. Results: A total of 63 patients (42 BOT, 21 OC) were analyzed. OC patients exhibited significantly higher SIR-125 and SIRI-125 values (p &lt; 0.001). ROC analysis demonstrated good diagnostic accuracy, with AUCs of 0.83 (SIR-125) and 0.82 (SIRI-125). SIR-125 showed higher specificity (0.83), while SIRI-125 had superior sensitivity (0.86). Conclusions: SIR-125 and SIRI-125 enhance diagnostic differentiation between OC and BOT, providing a simple, cost-effective preoperative tool. Future prospective studies are needed to validate these findings in broader patient populations.

Chemoembolization, Radioembolization, and Percutaneous Ablation: New Opportunities for Treating Ovarian Cancer Liver Metastasis

Parenchymal liver metastases from ovarian cancer, occurring in 2-12.5% of cases, significantly worsen prognosis. While surgery and systemic treatments remain primary options, unresectable or chemotherapy-resistant multiple liver metastases pose a significant challenge. Recent advances in liver-directed therapies, including radiofrequency ablation, microwave ablation, cryoablation, transarterial chemoembolization (TACE), and radioembolization, offer potential treatment alternatives. However, the efficacy of these techniques is limited by factors such as tumor size, number, and location. The ideal candidate for tumor ablation is a patient with paucifocal disease, a single tumor up to 5 cm or up to 3 tumors smaller than 3 cm and tumors 1 cm away from major bile ducts and high-flow vessels. Transarterial chemoembolization could be performed in patients with less than 70% tumor load. Differently, radioembolization is available with less limitation on the sites or number of liver cancers. Radioembolization techniques are also able to downsize liver metastases. However, there are limited data regarding the outcomes of loco-regional therapy in patients with hepatic metastases from ovarian cancer. Advancing liver-directed therapies through interventional oncology, combined with robust data on the oncological efficacy of these local treatments, will validate their potential as effective locoregional therapies for liver metastases. This could offer a promising treatment option for patients with ovarian cancer and unresectable hepatic metastases.

Sentinel node mapping in high-intermediate and high-risk endometrial cancer: Analysis of 5-year oncologic outcomes

To assess 5-year oncologic outcomes of apparent early-stage high-intermediate and high-risk endometrial cancer undergoing sentinel node mapping versus systematic lymphadenectomy. This is a multi-institutional retrospective, propensity-matched study evaluating data of high-intermediate and high-risk endometrial cancer (according to ESGO/ESTRO/ESP guidelines) undergoing sentinel node mapping versus systematic pelvic lymphadenectomy (with and without para-aortic lymphadenectomy). Survival outcomes were assessed using Kaplan-Meier and Cox proportional hazard methods. Overall, the charts of 242 patients with high-intermediate and high-risk endometrial cancer were retrieved. Data on 73 (30.1%) patients undergoing hysterectomy plus sentinel node mapping were analyzed. Forty-two (57.5%) and 31 (42.5%) patients were classified in the high-intermediate and high-risk groups, respectively. Unilateral sentinel node mapping was achieved in all patients. Bilateral mapping was achieved in 67 (91.7%) patients. Three (4.1%) patients had site-specific lymphadenectomy (two pelvic areas only and one pelvic plus para-aortic area), while adjunctive nodal dissection was omitted in the hemipelvis of the other three (4.1%) patients. Sentinel nodes were detected in the para-aortic area in eight (10.9%) patients. Twenty-four (32.8%) patients were diagnosed with nodal disease. A propensity-score matching was used to compare the aforementioned group of patients undergoing sentinel node mapping with a group of patients undergoing lymphadenectomy. Seventy patient pairs were selected (70 having sentinel node mapping vs. 70 having lymphadenectomy). Patients undergoing sentinel node mapping experienced similar 5-year disease-free survival (HR: 1.233; 95%CI: 0.6217 to 2.444; p = 0.547, log-rank test) and 5-year overall survival (HR: 1.505; 95%CI: 0.6752 to 3.355; p = 0.256, log-rank test) than patients undergoing lymphadenectomy. Sentinel node mapping does not negatively impact 5-year outcomes of high-intermediate and high-risk endometrial cancer. Further prospective studies are warranted.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) with cisplatin and doxorubicin in patients with ovarian cancer: A systematic review

PIPAC consists in delivering normothermic chemotherapy solution directly into the peritoneal cavity as an aerosol under pressure. Currently PIPAC is considered as a palliative treatment for patients suffering from non-resectable peritoneal carcinomatosis. We performed a SR to assess tolerance and response of this novel method among patient with OC. We searched electronic database PubMed, Embase, Web of Science, Clinical Trials.gov. We only included clinical studies reporting PIPAC with cisplatin and doxorubicin in patients with ovarian cancer. This systematic review included 4 studies. In 3 studies all patients were pretreated with cytoreductive surgery, in 1 study surgery was performed in 8/34 (23 %) patients. Mean PCI at first PIPAC procedure ranged from 16.3 to 19.6. All studies reported the proportion of patients with ascites at the first PIPAC with a pooled rate of 48,3 %. Pooled rate of CTCAE Grade 3 toxicity calculated on the total number of PIPAC was 6 % and Grade 4 was 0.9 %. One study reported two cases of small bowel perforation related or potentially related to PIPAC. On study reported a cumulative survival after 400 days of 62 % and a mean actuarial survival time of all patients who underwent PIPAC of 442 days. In another study the mean time to progression was 144 days (95 % CI 122-168 days). This systematic review demonstrated that PIPAC with cisplatin and doxorubicin appear to have a good safety profile with low toxicity and encouraging trend in terms of overall survival.

Fertility-Sparing Treatments in Endometrial Cancer: A Comprehensive Review on Efficacy, Oncological Outcomes, and Reproductive Potential

Endometrial cancer (EC) affects 3–14% of women under 40 who wish to preserve their fertility. The standard treatment for EC is a hysterectomy with salpingo-oophorectomy. However, for those desiring fertility preservation, oral progestogens such as medroxy-progesterone acetate (MPA) or megestrol acetate (MA) are the most common therapies in Fertility-Sparing Treatment (FST). Other treatments include gonadotropin-releasing hormone agonist (GnRHa), levonorgestrel-releasing intrauterine system (LNG-IUS), and metformin plus progestin. This comprehensive review evaluates the best FST options for women with reproductive potential. PubMed, EMBASE, and Scopus were searched in June 2023 using specific keywords. Studies included in the review focused on patients with EC undergoing FST, with outcomes such as complete response rate (CRR), recurrence rate (RR), pregnancy rate (PR), and live birth rate. Eighteen studies met the inclusion criteria, involving 23,976 patients. In only-oral progestin trials, CRR ranged from 18% to 100%; RR ranged from 0% to 81.8%; Death Rate ranged from 0% to 3.6%. In studies combining oral progestin with LNG-IUS, CRR ranged from 55% to 87.5%; RR ranged from 0% to 41.7%; Death Rate was 0%. Most patients with Stage IA EC received MPA or MA. Fertility-related outcomes were reported in 15 studies. PR ranged from 4 to 44 patients in trials involving only oral progestins. When combining oral progestin with LNG-IUS, PR ranged from 1 to 46 patients. Progestin therapy, including oral MPA and MA, is considered safe and effective, with limited evidence supporting the use of LNG-IUS.

Robotic single-port (da Vinci SP) versus multiport (da Vinci Xi) for the treatment of atypical endometrial hyperplasia and endometrial cancer: A multi-institutional comparison of surgical outcomes

The da Vinci SP robotic platform offers a novel single-port approach for minimally invasive surgery. Despite its potential, data on its safety and performance in gynecologic oncology remain limited. We aimed to compare surgical outcomes of da Vinci SP versus da Vinci Xi systems in the staging of endometrial cancer (EC). This is a multi-institutional study. Data of consecutive patients with apparent early-stage EC or atypical endometrial hyperplasia who underwent robotic surgery between January 2023-March 2025 were collected. The primary outcome was to compare the surgical outcomes between da Vinci SP and da Vinci Xi. A total of 189 patients were included: 97 (51.3 %) underwent SP surgery and 92 (48.7 %) Xi. The median (range) of operative time, estimated blood loss, and postoperative hospital stay were comparable for SP and Xi groups (140 [70-296] vs. 143 [60-297] min, p = 0.66, 40 [0-250] vs. 64 [0-1300] mL, p = 0.12, 3 [1-11] vs. 3[1-10] days, p = 1). Docking time was significantly shorter in the SP group (10 [4-31] vs. 12 [7-30] min for SP and Xi, respectively, p = 0.004). Intraoperative or post-operative complications rates were comparable (p = 0.30 and p = 0.14,respectively). The patient-reported pain score was significantly lower at 12h and 24h in the Xi group (p = 0.001), while was comparable at 48h after surgery (p = 1). The da Vinci SP system appears to be non-inferior to the multiport da Vinci Xi for surgical staging of early-stage EC. Comparable perioperative outcomes support its clinical use, although patient selection criteria and long-term results require further investigation.

Fertility-sparing management of low-grade endometrial stromal sarcoma: A systematic review of oncologic and reproductive outcomes

Low-grade endometrial stromal sarcoma (LG-ESS) is a rare malignancy and the standard of care, precludes future childbearing. Although fertility-sparing treatment (FST) may be considered in carefully selected patients, high-quality evidence regarding its efficacy and safety is limited. This review aims to systematically evaluate the oncologic and reproductive outcomes associated with conservative treatment for LG-ESS. Pubmed Database, Scopus Database and Embase Database were screened in September 2024 from the first publication about women with LG-ESS treated with a surgical FST. We included the studies containing data about oncologic, and reproductive outcomes. This study adheres to PRISMA guidelines and is registered with PROSPERO (CRD42024605140). The quality of the studies was assessed using the Newcastle-Ottawa scale. 9 studies fulfilled inclusion criteria, and 89 patients were analyzed. Recurrence was observed in 51 out of 89 patients (57.3 %) with a mean recurrence-free interval ranging between 3 and 40.5 months. A mortality rate of 1.1 % was observed, with a mean follow-up duration ranging from 38.5 to 84.5 months. The overall pregnancy rate was 41.5 % and the live birth rate was 78.1 %. The preterm delivery rate was 8 % and 3.9 % of patients required assisted reproduction technology. Considering the limitations of the available evidence, FST in women with LG-ESS carries a relatively high risk of tumor relapse, though it does not increase the risk of death. Fertility outcomes seem to be encouraging. Resection of the malignant uterine lesion combined with adjuvant hormonal treatment may be considered for selected early-stage patients, with close follow-up.

Detection rate of sentinel lymph nodes in early-stage endometrial cancer according to age

Sentinel lymph node (SNL) mapping plays a crucial role in staging patients with an apparent early-stage endometrial cancer. Older age may be associated with lower detection rates due to factors such as decreased lymphatic flow; but consensus is lacking. This study aims to evaluate the impact of age on the SNL detection rate in patients undergoing minimally invasive surgical staging for endometrial cancer. This multicenter retrospective study included apparent early-stage endometrial cancer patients undergoing minimally invasive surgical staging, including SLN mapping across four ESGO-accredited centers (2020-2023). Patients were categorized into two age groups: <65 years, defined as younger adults and ≥65 years, defined as older adults. Univariate and multivariate logistic regression models were used to identify predictors of bilateral mapping. Overall, 642 patients were identified: 342 (53.3%) patients were classified as younger adults and 300 (46.7%) as older adults. The overall bilateral SLN detection rate was 89.3%, with no or unilateral detection in 10.7% of patients. Older adults had a significantly lower bilateral detection rate than younger adults (85.0% vs. 93.0%, p = 0.005). Multivariate analysis identified age ≥65 years as the only independent predictor of failed bilateral mapping (OR 2.2, 95 % CI 1.3-3.8, p = 0.003). Other clinical, surgical, and pathological factors were not associated with mapping failure. Age ≥65 is independently associated with decreased bilateral SLN detection in early-stage endometrial cancer. Nevertheless, SLN biopsy remains a feasible and reliable staging method in older adults when performed using standardized techniques by experienced surgeons.

Major determinants of survival in recurrent endometrial cancer—the role of secondary cytoreductive surgery: a multicenter study

The main objective of the study was to assess the influence of different clinical and therapeutic variables on the oncological outcomes of patients with endometrial cancer relapse. In particular, we evaluated the impact of cytoreductive surgery with the achievement of complete gross resection. This is a multicenter retrospective cohort study conducted in three centers in Italy and including all patients with first relapse of endometrial cancer from January 2010 to December 2021. Data from 331 women with recurrent endometrial cancer were analyzed. Secondary cytoreductive surgery was performed in 56.2% of cases (186 patients). Complete gross resection was achieved in 178 patients (95.7%). Complete gross resection conferred a statistically significant survival benefit both for post-relapse survival and post-relapse free survival (3 years post-relapse survival: 75.4% vs 56.4%, p<0.001; 3 years post-relapse free survival: 32.6% vs 26.5%, p=0.027). At multivariate Cox regression analysis, age ≥75 years, Eastern Cooperative Oncology Group Performance Status ≥2, the advanced-metastatic risk group, complete gross resection, and multiple site relapses were identified as independent significant predictors for post-relapse survival; regarding post-relapse free survival, only age ≥75, the high and advanced-metastatic risk groups, and complete gross resection confirmed their statistical significance. Secondary cytoreductive surgery with achievement of complete gross resection was confirmed to be an independent positive predictor for survival in patients with recurrent endometrial cancer and should be considered a valid primary treatment in the therapeutic decision-making process.

Is there a role for the sentinel lymph node in endometrial atypical hyperplasia? Insights from an ESGO-accredited Institution

This study investigates the outcomes of patients with premalignant endometrial findings on biopsy who underwent hysterectomy with sentinel lymph node (SLN) excision and were subsequently diagnosed with endometrial cancer (EC). It aims to highlight the role of nodal assessment in guiding postoperative treatment strategies. Additionally, the study compares surgery complication rates between patients who underwent SLN mapping and those who did not. This retrospective, observational, single-center study was conducted at Udine Hospital between April 2021 and July 2024. 63 patients diagnosed with atypical hyperplasia on endometrial biopsy who underwent hysterectomy and bilateral salpingo-oophorectomy, with or without SLN mapping, were included. All procedures were performed using minimally invasive surgery. Of the 63 patients, 35 (55.6 %) had confirmed atypical hyperplasia on uterine pathology, while 23 (36.5 %) were diagnosed with EC on final pathology. Of the patients who underwent SLN mapping, 18 (43 %) received a final diagnosis of EC and were accurately staged and treated accordingly. In contrast, within the group of patients treated without SLN mapping, 5 (24 %) were diagnosed with EC on final pathology and didn't receive proper staging. No nodal metastases were found in both groups. There was no statistically significant difference in operating time and complication rates between the two groups (with or without SLN mapping), further supporting the procedure's safety. This study's findings underscore the significance of incorporating SLN mapping into hysterectomy and bilateral salpingo-oophorectomy for patients with atypical hyperplasia. This approach enhances accurate staging for patients diagnosed with endometrial cancer on final pathology.

Impact of optimal secondary cytoreductive surgery on survival outcomes in women with recurrent endometrial carcinoma: A systematic review and meta‐analysis

AbstractBackgroundManagement of recurrent endometrial carcinoma (EC) represents a challenge. Although a complete resection of visible disease at secondary surgery (R0) is recommended, the impact of R0 on survival outcomes is unclear and pooled data are lacking.ObjectiveTo quantitatively assess the impact of R0 on survival outcomes in women with EC recurrence.Search StrategyA systematic review and meta‐analysis was performed searching eight electronic databases from their inception up to January 2024.Selection CriteriaAll peer‐reviewed studies that assessed quantitatively the impact of R0 on survival outcomes in women at first EC recurrence were included.Data Collection and AnalysisHazard ratio (HR) with 95% confidence interval (CI) for death of any cause and secondary recurrent or progressive disease in women with EC recurrence who underwent R0 compared to non‐optimal secondary surgical cytoreduction (R1) were pooled and assessed at both univariable and multivariable analyses.Main ResultsThree studies with 442 patients were included. At univariate analysis, in women with EC recurrence and R0 compared to women with EC recurrence and R1, pooled HR was 0.451 (95% CI: 0.319–0.638) for death from any cause, and 0.517 (95% CI: 0.298–0.895; p = 0.019) for recurrent or progressive disease.At multivariate analysis, in women with EC recurrence and R0 compared to women with EC recurrence and R1, pooled HR was 0.447 (95% CI: 0.255–0.783; p = 0.005) for death from any cause, and 0.585 (95% CI: 0.359–0.952; p = 0.031) for recurrent or progressive disease.ConclusionIn women with EC recurrence, R0 is an independent prognostic factor, decreasing the risk of death from any cause by approximatively 55%, and of recurrent or progressive disease by approximatively 40%, compared to R1.

Predictive factors for adnexal involvement in endometrial cancer FIGO stage IIIA

Understanding ovarian involvement incidence and risk factors in women with endometrial cancer may inform the decision of ovary preservation. Our retrospective study included all consecutive fully surgically staged patients with endometrial cancer who underwent primary surgery between January 2005 and November 2021, assessing the incidence of ovarian metastasis, its role as a prognostic factor for recurrence and death, and evaluated predictors of adnexal involvement. Women with International Federation of Gynecology and Obstetrics (FIGO) 2009 IIIA endometrial cancer comprised 2.3% of the population (36 of 1535 included patients), 23 (63.9%) with endometrioid histology, and a median age of 57.0 years (range 47.7-66.7). A higher body mass index, post-menopausal status, endometrioid histotype, and β-catenin expression were associated with a lower risk of adnexal involvement. Conversely, dMMR phenotype, p53 expression, myometrial infiltration >50%, lymphovascular space invasion, and cervical stromal invasion were independent predictors of an increased risk of adnexal involvement. A total of 145 (9.5%) patients had adnexal involvement, with an incidence rate of 0.27/100 person-days. Overall survival for FIGO (2009) stage IIIA was 88.9%. Our study showed that ovarian preservation may be considered for younger patients with low-risk endometrial cancer (G1 and G2 tumors, absence of lymphovascular space invasion, no cervical involvement, and myometrial invasion <50%), adding a favorable predictive role to higher body mass index and high β-catenin expression.

Substantial lymph-vascular space invasion (LVSI) as predictor of distant relapse and poor prognosis in low-risk early-stage endometrial cancer

The aim of this study is to analyze the prognostic role of lymph-vascular space invasion (LVSI), evaluated in a semi-quantitative fashion on prognosis of early stage, low risk endometrial cancer (EC). We enrolled patients who underwent surgery for endometrial cancer between 2003 and 2018 in two referral cancer center. All patients had endometrioid EC, G1-G2, with myometrial invasion <50%, and no lymph-node involvement. LVSI was analyzed in a semi-quantitative way, according to a 3-tiered scoring system in absent, focal and substantial. Among 524 patients, any positive LVSI was found in 57 patients (10.9%) with focal LVSI (n=35, 6.7%) and substantial LVSI (n=22, 4.2%). Substantial LVSI was associated to higher rate of G2 (p<0.001), myometrial infiltration (p=0.002) and greater tumor dimensions (p=0.014). Patients with substantial LVSI were more likely to receive adjuvant treatment (6.6% vs. 52.6%, p<0.001). The 5-year OS was 99.5% in patients with absent LVSI and 70.6% in those with substantial LVSI (p<0.001). The 5-year disease free survival (DFS) was 93.6% in patients with absent LVSI and 56.5% in those with substantial LVSI (p<0.001). The rate of distant failures increased from 1.8% for absent LVSI to 22.7% for substantial LVSI (p=0.002). In univariate analysis substantial LVSI was the strongest predictor of poor overall survival (hazard ratio [HR]=11.9, p=0.001). Multivariate analysis showed that substantial LVSI was an independent predictive factor of both recurrence (HR=5.88, p=0.001) and distant failure (HR=10.6, p=0.006). Substantial LVSI represents the strongest independent risk factor for decreased survival and distant relapse, indicating a role for potential hematogenous dissemination.

Evaluation of the one-step nucleic acid amplification method for rapid detection of lymph node metastases in endometrial cancer: prospective, multicenter, comparative study

To evaluate the diagnostic performance of the one-step nucleic acid amplification (OSNA) method for the detection of sentinel lymph node (SLN) metastases in women with apparent early-stage endometrial cancer compared with standard ultrastaging. Prospective, multicentric, interventional study. Patients with apparent early-stage endometrial cancer who underwent primary surgical staging with SLN mapping were included. SLNs were serially sectioned with 2 mm slices perpendicular to the longest axis of the node: the odd slices were submitted to ultrastaging, whereas the even slices were submitted to the OSNA analysis. Diagnostic performance was calculated taking ultrastaging as referral standard. Three-hundred and sixteen patients with 668 SLNs were included. OSNA assay detected 22 (3.3%) positive SLNs, of which 17 (2.5%) were micrometastases and 5 (0.7%) macrometastases, whereas ultrastaging detected 24 (3.6%) positive SLNs, of which 15 (2.2%) were micrometastases and 9 (1.3%) macrometastases (p=0.48). Regarding negative SLNs, OSNA detected 646 (96.7%) negative nodes, including 8 (1.2%) isolated tumor cells, while ultrastaging detected 644 (96.4%) negative nodes with 26 (3.9%) isolated tumor cells. Specificity of OSNA was 98.4% (95% CI 97.5 to 99.4), accuracy was 96.7% (95% CI 95.4 to 98.1), sensitivity was 50% (95% CI 30.0 to 70.0), while negative predictive value was 98.1% (95% CI 97.1 to 99.2). Discordant results were found in 22 SLNs (3.3%) corresponding to 20 patients (6.3%). These were 10 (1.5%) false-positive SLNs (all micrometastases): one (0.1%) of these was a benign epithelial inclusion at ultrastaging. There were 12 (1.8%) false-negative SLNs of OSNA, of which 9 (1.3%) were micrometastases and 3 (0.5%) macrometastases. Overall, 17/668 (2.5%) benign epithelial inclusions were detected at ultrastaging. The OSNA method had high specificity and high accuracy in detecting SLN metastasis in apparent early-stage endometrial cancer. The advantage of the OSNA method could be represented as the possibility to analyze the entire lymph node thus eliminating sampling bias.

Molecular classification of endometrial carcinoma on endometrial biopsy: an early prognostic value to guide personalized treatment

Molecular features are essential for estimating the risk of recurrence and impacting overall survival in patients with endometrial cancer. Additionally, the surgical procedure itself could be personalized based on the molecular characteristics of the tumor. This study aims to assess the feasibility of obtaining reliable molecular classification status from biopsy specimens collected during hysteroscopy to better modulate the appropriate surgical treatment. This monocentric, retrospective, observational study was conducted on 106 patients who underwent a biopsy procedure followed by radical surgery for endometrial cancer, with concurrent molecular investigation. The molecular classification was determined through immunohistochemical staining for p53 and mismatch repair proteins, along with gene sequencing for POLE. Overall, 106 patients underwent molecular investigation, which was finally achieved on 99 patients (93.4%). Among these, the molecular analysis was conducted in 71 patients (67%) on the pre-operative endometrial biopsy and on the final uterine specimen in 28 patients (26.4%). Most of the endometrial biopsies were performed using Bettocchi hysteroscopy (66%). Molecular analysis was not possible in seven patients (6.6%), with six cases due to sample inadequacy and one case attributed to intra-mucosal carcinoma. The molecular results showed that the copy number low sub-group was the most common, and five cases of 'multiple classifiers' were observed in the low-risk category. Our experience in obtaining molecular information from biopsy samples underscores the feasibility and efficacy of this technique, even in small tissue samples. This capability helps define the prognostic group of patients, facilitates timely decision-making, and develops a personalized strategy for each patient.

Mesonephric-Like Adenocarcinomas a Rare Tumor: The Importance of Diagnosis

Mesonephric-like adenocarcinomas (MLA) are rare neoplasms that arise in the uterine body and ovary and have been added to the World Health Organisation’s recent 2020 classification of female genital cancers. The pathogenesis of MLA is unknown and it remains debated whether they represent mesonephric carcinomas (Wolffian) arising in the endometrium/ovary or endometrioid carcinomas (Müllerian) closely mimicking mesonephric carcinomas. Here we report the case of a 57-year-old woman with an initial misdiagnosis of endometrioid adenocarcinoma on diagnostic biopsy. The patient came to our clinical evaluation for the appearance of menometrorrhagia complicated by anemia for several months. Therefore, she underwent pelvic echo-flowmetry, with indication for diagnostic hysteroscopy with endometrial biopsy, which yielded a positive result for endometrioid endometrial adenocarcinoma. Following staging CT scan and targeted examinations on pulmonary findings, the patient underwent surgery with surprise of definitive diagnosis deponent for endometrial MLA. Our intention is to establish a brief review of the scientific evidence in the literature and the tools available for a correct histological diagnosis, in the light of the scant anatomopathological evidence. Our question gives rise to the motive for the publication: is immunohistochemistry the right way to resolve the diagnostic error at histology, which is usually the only source of diagnostic certainty? This case is intended to alert of diagnostic error that risked having the patient treated as a neoplasm with a favorable prognosis and low degree of aggressiveness instead of for a very aggressive and poor prognosis tumor such as MLA.

Comparison of Different Near-Infrared Technologies to Detect Sentinel Lymph Node in Uterine Cancer: A Prospective Comparative Cohort Study

Objectives: Sentinel lymph node biopsy is considered a crucial step in endometrial cancer staging. Cervical injection has become the most favored technique and indocyanine green has been demonstrated to be more accurate than other tracers. Different near-infrared camera systems are currently being used to detect indocyanine green in sentinel lymph nodes and have been compared in different patients. The present study aimed to determine the number and site of sentinel lymph nodes detected in the same patients with two different near-infrared technologies. Methods: This is a prospective, single-center, observational, non-sponsored study. Patients with presumed uterine-confined endometrial cancer were prospectively enrolled. After cervical injection, two different near-infrared cameras were used to detect sentinel lymph nodes at the same time: Olympus, Tokyo, Japan—considered the standard (SNIR); and Medtronic, Minneapolis, MN, USA with VISION SENSE® which is a new laser near-infrared (LNIR) fluorescence laparoscope. The two cameras were alternatively switched on to detect sentinel lymph nodes in the same patients. Results: Seventy-four consecutive patients were included in the study. Most of the patients were diagnosed with endometrioid histology (62, 83.8%), FIGO stage IA (48, 64.9%), grade 2 (43, 58.1%), and underwent surgery with laparoscopic approach (70, 94.0%). The bilateral detection rate was 56/74 (75.7%) with SNIR and 63/74 (85.1%) with LNIR (p = 0.214). The total number of sentinel lymph nodes identified in the left hemipelvis was 65 and 70 with SNIR and LNIR, respectively; while in the right hemipelvis, there were 74 and 76, respectively. The median number of sentinel lymph nodes identified with SNIR and LNIR was 2 (range, 0–4) and 2 (range, 0–4), respectively (p = 0.370). No difference in site of sentinel lymph node detection was evident between the two technologies (p = 0.994). Twelve patients (16.2%) had sentinel lymph node metastasis: in all cases metastatic sentinel lymph nodes were detected both with Olympus and LNIR. Conclusions: No difference in bilateral detection rate and number or site of sentinel lymph node detection was evident comparing two different technologies of near-infrared camera for ICG detection in endometrial cancer patients. No difference in sentinel lymph node metastases identification was detected between the two technologies.

Laparoscopic vs. robotic-assisted laparoscopy in endometrial cancer staging: large retrospective single-institution study

The aim of this study is to analyze and draw the potential differences between the robotic-assisted surgery (RS) and the laparoscopy (LPS) in endometrial cancer staging. In this single-institution retrospective study we enrolled 1,221 consecutive clinical stage I-III endometrial cancer patients undergone minimally invasive surgical staging. We compared patients treated by LPS and by RS, on the basis of perioperative and oncological outcomes (disease-free survival [DFS] and overall survival [OS]). A sub-analysis of the high-risk endometrial cancer population was performed in the 2 cohorts. The 2 cohorts (766 treated by LPS and 455 by RS) were homogeneous in terms of perioperative and pathological data. We recorded differences in number of relapse/progression (11.7% in LPS vs. 7% in RS, p=0.008) and in number of deaths (9.8% in LPS vs. 4.8% in RS, p=0.002). Whereas, univariate and multivariate analyses according to DFS and OS confirmed that the surgical approach did not influence the DFS or the OS. In the multivariable analysis the association of the age and grading was significant for DFS and OS. In the sub-analysis of the 426 high risk EC patients (280 in LPS and 146 in RS) the univariate and the multivariate confirmed the influence of the age in DFS and OS, independently of the minimally invasive approach. In our large retrospective analysis, we confirmed that the RS and LPS have similar efficacy and safety for endometrial cancer staging also for the high-risk endometrial cancer patients.

Laparoscopic sentinel node mapping with intracervical indocyanine green injection for endometrial cancer: the SENTIFAIL study – a multicentric analysis of predictors of failed mapping

Laparoscopy is commonly used for endometrial cancer treatment, and sentinel lymph node (SLN) mapping has become the standard procedure for nodal assessment. Despite the standardization of the technique, there is no definitive data regarding its failure rate. The objective of this study is to identify factors associated with unsuccessful SLN mapping in endometrial cancer patients undergoing laparoscopic SLN mapping after intracervical indocyanine green (ICG) injection. We retrospectively evaluated a consecutive series of endometrial cancer patients who underwent laparoscopic SLN mapping with intracervical ICG injection, in four oncological referral centers from January 2016 to July 2019. Inclusion criteria were biopsy-proven endometrial cancer, total laparoscopic approach, and intracervical ICG injection. Exclusion criteria were evidence of lymph node involvement or extrauterine disease at pre-operative imaging, synchronous invasive cancer, the use of tracers different from ICG, and the use of neoadjuvant treatment. Bilateral and failed bilateral SLN mapping groups were compared for clinical and pathological features. In patients with an unsuccessful procedure, side-specific lymphadenectomy was performed. Logistic regression was used to identify predictors of failure. A total of 376 patients were included in the study. The overall bilateral and unilateral SLN detection rates were 96.3%, 76.3%, and 20.0% respectively. The failed bilateral mapping detection rate was 23.7%. The median number of sentinel nodes removed was 2.2 (range, 0-5). After multivariate analysis, lymph vascular space involvement [OR 2.4 (1.04-1.12), P=0.003], non-endometrioid histology [OR 3.0 (1.43-6.29), P=0.004], and intraoperative finding of enlarged lymph node [OR 2.3 (1.01-5.31), P=0.045] were identified as independent predictors of failure of SLN mapping. Lymph vascular space involvement, non-endometrioid histology, and intra-operative finding of enlarged lymph nodes were identified as independent risk factors for unsuccessful mapping in patients undergoing laparoscopic SLN mapping.

Standard ultra-staging compared to one-step nucleic acid amplification for the detection of sentinel lymph node metastasis in endometrial cancer patients: a retrospective cohort comparison

The objective of this study was to compared standard ultra-staging (SU) with one-step nucleic acid amplification (OSNA) for the detection of sentinel lymph node (SLN) metastasis in women with apparent uterine-confined endometrial cancer. All women underwent SLN identification with complete surgical staging. All SLNs were cut perpendicular to the long axis and two adjacent 5 µm sections were cut at each of two levels 50 µm apart. At each level, one slide was stained with hematoxylin and eosin and the other with immunohistochemistry using the AE1/AE3 anti-cytokeratin antibody, as well as one negative control slide for a total of five slides per block. For OSNA analysis, the 2 mm sections of the lymph nodes were homogenized to form a lysate. The lysate was then centrifuged and inserted into the RD 100i instrument where the isothermal amplification of CK19 mRNA was executed. Of the 396 patients included in the retrospective analysis, 214 were in the SU group, and 182 in the OSNA group. Overall 869 SLNs were identified (490 SU, 379 OSNA). Sixty patients exhibited SLN metastasis (34 SU, 26 OSNA). Macrometastasis, micrometastases, and isolated tumor cells (ITC) were 5.1%, 4.1%, and 0.2%, respectively, in the US group, and 2.4%, 6.3%, and 0.1%, respectively, in the OSNA group (p=0.022). The OSNA assay detected a higher rate of micrometastasis and a lower rate of macrometastasis and ITC when compared with SU. The clinical and prognostic impact of ITC is debatable and controversial. Further studies are needed to clarify the respective roles of the OSNA and SU methods, and the possible role of ITC in the prognosis of patients with apparent early-stage endometrial cancer.

Clinical outcome of recurrent endometrial cancer: analysis of post-relapse survival by pattern of recurrence and secondary treatment

Recurrence of endometrial cancer is an important clinical challenge, with median survival rarely exceeding 12 months. The aim of this study was to analyze patterns of endometrial cancer recurrence and associations of these patterns with clinical outcome. The study included patients with endometrial cancer who underwent primary surgical treatment with or without adjuvant treatment between July 2004 and June 2017 at the Gynaecologic Oncology Unit of one of three tertiary hospitals of the Catholic University Network in Italy with complete follow-up data available. Information on the date and pattern of recurrence was retrieved for each relapse. Post-relapse survival was recorded as the time from the date of recurrence to the date of death or last follow-up. Survival probabilities were compared using log rank tests, and associations of clinico-pathological characteristics with post-relapse survival were tested using Cox's regression models. A total of 1503 patients were included in the analysis. We identified 210 recurrences (14.0%) and 105 deaths (7.0%) at a median follow-up of 34 months (range 1-162). One hundred and fifty-eight recurrences (78.1%) occurred during the first two years of follow-up. Most recurrences were multifocal (n=121, 57.6%) and involved extrapelvic sites (n=38, 65.7%). Parameters associated with post-relapse survival in the univariate analysis included histotype, grade, time to recurrence, pattern of recurrence, number of relapsing lesions, and secondary radical surgery. Only the pattern of recurrence and secondary radical surgery were independent predictors of post-relapse survival in the multivariate analysis (p=0.025 and p=0.0001, respectively). Lymph node recurrence and the feasibility of secondary radical surgery were independent predictors of post-relapse survival in patients with recurrent endometrial cancer.

Clinical impact of surgical energy device (Caiman®) IN elderly patients with Endometrial Cancer (protocol ID: Cineca)

To investigate the clinical performance of the Caiman® energy device in class A radical laparoscopic hysterectomy (RLH) according to Querleu-Morrow classification, combined with bilateral salpingo-oophorectomy (BSO) and pelvic lymph node assessment in elderly patients with early-stage endometrial cancer (EC), specifically focusing on hemostatic effectiveness and safety. Single-institution, prospective observational study. Gynecologic Oncology Unit, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. Forty-three women over 65 years with FIGO stage IA or IB endometrioid EC were enrolled from September 2021 to August 2023. Use of Caiman® energy device in RLH combined with BSO and pelvic lymph node assessment in elderly patients. The primary endpoint was operative time, with secondary endpoints including perioperative outcomes and postoperative complications. Results demonstrated a median surgical time of 135 min, with no significant intraoperative complications attributed to the Caiman® device. Postoperative complications were minimal, with no severe complications (Grade 4 or 5) and a median hospital stay of two days. The study highlights the advantages of the Caiman® in enhancing surgical efficiency while minimizing risks for elderly patients, suggesting its potential for improving resource allocation and patient outcomes in oncologic surgery. The findings of this study suggest the feasibility of using the Caiman® device for surgical procedures in elderly patients with early-stage endometrial cancer. Future prospective randomized trials are needed to establish its efficacy compared to traditional surgical methods.

The exciting journey of progress: Exploring FIGO 2023 staging for endometrial cancer at a leading ESGO institution

The 2023 FIGO staging of endometrial cancer integrates tumor grade and histology along with molecular features that recognize the prognostic significance of p53 and POLE mutations, accounting for potential conflicts such as lymphovascular space invasion and subserosal invasion. In this single-institution retrospective study, data were collected on 229 endometrial cancer patients from January 2020 to September 2024 and re-stage them according to FIGO 2023 criteria. From FIGO stage 2009 IA, 70 patients do not cross stage (21 are FIGO 2023 IA1 and 49 IA2), 8 patients are upgraded to FIGO IC because of aggressive histotype; 1 is upstaged because of substantial LVSI, and 12 because of aggressive myoinfiltrating tumors (23 % of upstaging). From FIGO 2009 stage IB 34 patients remain in FIGO 2023 IB, while 5 become stage IIB (LVSI) and 27 IIC (aggressive myoinfiltrating), for a total of 32 upstages (48 % of upstaging). Within FIGO 2009 stage II, no proper upstage was possible. We observed a statistical correlation between stages and BMI, as well as between stages and age, for both FIGO 2009 (p = 0.009 and p < 0.001 respectively) and FIGO 2023 (p = 0.002 and p = 0.003 respectively) classifications. Additionally, a correlation was found between tumor grade and BMI (p = 0.02). The FIGO 2023 staging system is gaining importance as recent studies highlight the role of molecular classification in prognosis and personalized therapy. Updating our study's follow-up data will clarify its impact in clinical practice.

Assessment of sentinel Lymph node mapping with different volumes of Indocyanine green in early-stage ENdometrial cancer: the ALIEN study

To evaluate the impact of different volumes of indocyanine green (ICG) on the detection rate and bilateral mapping of sentinel lymph nodes in patients with apparent uterine-confined endometrial cancer. All patients who underwent surgical staging with sentinel node mapping in six reference centers were included. Two different protocols of ICG intracervical injection were used: (1) 2 mL group: total volume of 2 mL injected superficially; (2) 4 mL group: total volume of 4 mL, 2 mL deeply and 2 mL superficially. Logistic regression was used to analyze factors that could influence dye migration and detection rates. A sensitivity analysis was carried out to determine how independent variables could affect the sentinel node detection rate. Of 442 eligible patients, 352 were analyzed (172 in the 2 mL group and 180 in the 4 mL group). The bilateral detection rates of the 2 mL and 4 mL groups were 84.9% and 86.1%, respectively (p=0.76). The overall detection rate was higher with a volume of 4 mL than with 2 mL (97.8% vs 92.4%, respectively; p=0.024). In the univariate analysis the rate of bilateral mapping fell from 87.5% to 73.5% when the International Federation of Gynecology and Obstetrics (FIGO) 2009 tumor stage was >IB (p=0.018). In the multivariate analysis, for both overall and bilateral detection rates a statistically significant difference emerged for the volume of ICG injected and FIGO 2009 stage >IB. Increasing body mass index was associated with worse overall detection rates on univariate analysis (p=0.0006), and significantly decreased from 97% to 91% when the body mass index exceeded 30 kg/m In patients with early-stage endometrial cancer, a volume of 2 mL ICG does not seem to compromise the bilateral detection of sentinel lymph nodes. In women with obesity and FIGO 2009 stage >IB, a 4 mL injection should be preferred.

Early Postoperative Albumin and Neutrophil Dynamics for Risk Stratification After Cytoreductive Surgery in Ovarian Cancer: A Retrospective Multicenter Cohort Study

Background and Objectives: Serum albumin is a widely available and inexpensive biomarker that reflects nutritional status and physiological reserve. Hypoalbuminemia has been linked to poor postoperative outcomes in surgical oncology; however, its role in predicting early complications after cytoreductive surgery for ovarian cancer, as well as the potential contribution of systemic inflammatory indices in nutritionally preserved patients, remains incompletely understood. This study aimed to evaluate the predictive value of early postoperative serum albumin for early surgical complications and to explore whether inflammatory indices could offer additional prognostic information in patients with adequate albumin levels. Materials and Methods: We conducted a retrospective observational cohort study including patients undergoing cytoreductive surgery for ovarian cancer at two Italian tertiary referral centers between July 2023 and December 2025. Postoperative serum albumin was measured on the first postoperative day. Systemic inflammatory parameters were assessed using perioperative changes in neutrophils and composite indices. Early postoperative complications occurring within 30 days were recorded. Multivariable logistic regression analyses were performed, and subgroup analyses were conducted in patients with postoperative albumin ≥3 g/dL. Receiver operating characteristic (ROC) analysis was used to identify an optimal cutoff for significant inflammatory predictors. Results: A total of 121 patients were included, of whom 30 developed early postoperative complications. Patients with complications had significantly lower postoperative albumin levels than those without complications (median 2.75 vs. 3.09 g/dL; p &lt; 0.001). In multivariable analysis, lower postoperative albumin independently predicted early complications (OR 0.26, 95% CI 0.06–0.86). In the subgroup of patients with preserved albumin levels (≥3 g/dL), a smaller postoperative neutrophil decline independently predicted complications (OR 1.56, 95% CI 1.12–2.70). A neutrophil drop cutoff of −1.15 × 103/dL showed good specificity (81.5%) and high negative predictive value (95.7%). Conclusions: Early postoperative serum albumin is a strong predictor of early surgical complications after cytoreductive surgery for ovarian cancer. In patients with preserved nutritional status, dynamic neutrophil changes provide additional prognostic information. Incorporating low-cost metabolic and inflammatory biomarkers may enhance early postoperative risk stratification and support more personalized patient management.

Predictive factors of surgical complications after pelvic exenteration for gynecological malignancies: a large single-institution experience

To evaluate pre-operative predictors of early (<30 days) severe complications (grade Dindo 3+) in patients with gynecological malignancy submitted to pelvic exenteration (PE). We retrospectively analyzed 129 patients submitted to surgery at Fondazione Policlinico Gemelli between 2010 and 2019. We included patients affected by primary or recurrent/persistent cervical, endometrial, or vulvar/vaginal cancers. Post-operative complications were graded according to the Dindo classification. Logistic regression was used to analyze potential predictors of complications. We performed 63 anterior PE, 10 posterior PE, and 56 total PE. The incidence of early severe post-operative complications was 27.9% (n=36), and the early mortality rate was 2.3% (n=3). More frequent complications were related to the urinary diversion and intestinal surgery. In univariable analysis, hemoglobin ≤10 g/dL (odds ratio [OR]=4.2; 95% confidence interval [CI]=1.65-10.7; p=0.003), low albumin levels (OR=3.9; 95% CI=1.27-12.11; p=0.025), diabetes (OR=4.15; 95% CI=1.22-14.1; p=0.022), 2+ comorbidities at presentation (OR=5.18; 95% CI=1.49-17.93; p=0.012) were predictors of early severe complications. In multivariable analysis, only low hemoglobin and comorbidities at presentation were independent predictors of complications. Pelvic exenteration is an aggressive surgery characterized by a high rate of post-operative complications. Pre-operative assessment of comorbidities and patient health status are crucial to better select the right candidate for this type of surgery.

SLYMEC II study: Overall survival analysis of the impact of LVSI in apparent early stage endometrioid endometrial cancer

In our initial report of the SLYMEC study we published the results evaluated the prognostic impact of substantial lymphovascular space invasion (LVSI) on the sentinel lymph node status and the impact of the different types of LVSI on 3-year disease-free survival. The aim of the SLYMEC II study was to assess the impact of focal and substantial lymphovascular space invasion on 5-years overall survival in the subgroup of patients with endometrioid endometrial cancer. A total of 2030 patients were included in the analysis from the original data set. Focal LVSI were identified in 131 patients (6.4 %), whereas 319 patients (15.7 %) showed substantial LVSI at final pathology. Among 1876 patients who underwent minimally invasive surgery (92.6 %), 442 patents (21.8 %) underwent robotic assisted surgery, whereas and 150 patients (7.6 %) patients underwent open surgery. Rate of overall survival at 5 years was 83.6 % versus 100 % for substantial and focal LVSI groups, respectively (HR for death = 2.1 [95 % CI, 1.4 to 3.2]; P < 0.0001). Patients with endometrioid endometrial cancer having substantial LVSI after surgery showed an increased risk of death in the after 5-years overall survival when compared to patients with negative, or focal LVSI. The presence of positive LVSI in patients with positive sentinel nodes showed a trend toward reduced 5-year overall survival compared to SLN-negative patients, although it did not reach statistical significance.

Proton Beam Therapy in Gynecological Cancers: A Systematic Review of Indications, Complications, and Limitations

Background and Objectives: Gynecological cancers frequently require radiation therapy (RT) in primary, adjuvant, or salvage settings. However, photon-based RT is associated with non-negligible toxicity, and treatment of pelvic recurrences after prior irradiation remains challenging. Proton beam therapy (PBT), due to its favorable dose distribution and reduced exposure of organs at risk (OARs), has emerged as a potential alternative, particularly in re-irradiation scenarios. Despite its expanding use in other malignancies, evidence supporting PBT in gynecologic cancers remains limited. This systematic review aims to investigate the use of PBT in gynecological cancers and its associated complications. Materials and Methods: This systematic review was conducted according to PRISMA guidelines and registered in PROSPERO. A comprehensive search (2000–2025) identified studies investigating PBT in gynecologic cancers. Eligible designs included randomized trials and prospective and retrospective series. Reported adverse events were categorized as GI, GU, or other, and only grade ≥3 CT-CAE complications were considered. Results: Of 580 records screened, 9 studies comprising 232 patients met inclusion criteria. Most patients were treated for endometrial (n = 147) or cervical (n = 75) cancer; 90 received chemotherapy. Overall, severe toxicity occurred in 15.2% of patients. GI complications ranged from 0–14% and GU from 0–33%. Complication rates were lowest in adjuvant or de novo treatment series (0–10%), whereas re-irradiation cohorts showed higher rates (up to 33% GU). Comparative studies suggested a possible advantage of PBT over IMRT, particularly for GI toxicity, though data remain limited. Conclusions: Severe GI and GU toxicity after PBT in gynecologic cancers appears infrequent, particularly in primary and adjuvant settings, though re-irradiation remains challenging. Current evidence is restricted to small and heterogeneous studies. Ongoing phase II trials will provide prospective data to clarify feasibility, toxicity, and long-term outcomes. Until then, PBT in gynecologic oncology should be regarded as investigational.

Levonorgestrel-releasing intra-uterine device alone for managing early-stage endometrial cancer and endometrial hyperplasia with atypia in patients unfit for surgery: the ENDOIUD study

This study aimed to clarify the role of levonorgestrel-releasing intra-uterine device as a stand-alone therapy in managing patients with endometrial atypical hyperplasia/endometrial cancer who are not suitable for surgery, through the evaluation of cause-specific survival and the control of vaginal bleeding. This is a retrospective, multi-center study conducted in 9 referral gynecologic centers in Italy. Data regarding the clinical and oncological outcomes of patients with endometrial atypical hyperplasia/endometrial cancer (International Federation of Gynecology and Obstetrics Stage I) were analyzed. Patients were judged unsuitable for surgery due to an American Society of Anesthesiologists score ≥3 and the presence of multiple severe co-morbidities and, therefore, triaged to receive levonorgestrel-releasing intra-uterine device alone. A total of 78 women were enrolled. Fifteen patients (19.2%) had a diagnosis of endometrial atypical hyperplasia, whereas the other 63 (80.8%) had endometrial cancer. The baseline hemoglobin levels averaged 11.6 (range; 6-16), increasing to 12.1 (range; 7.8-14.9) during follow-up after levonorgestrel-releasing intra-uterine device insertion (p = .003). No patient experienced any side effects, and bleeding control was rated as excellent in most patients. Median disease-free survival was 43 months (range; 5-120) and median overall survival was 45 months (range; 5-120). Levonorgestrel-releasing intra-uterine device alone is a safe and effective approach, showing no side effects, and a promising oncological outcome in women with early-stage endometrial atypical hyperplasia/endometrial cancer unfit for surgery. Future prospective studies are required to clarify how to select patient candidates for this therapy and how to predict response to levonorgestrel-releasing intra-uterine device.

Neoadjuvant chemotherapy followed by interval surgery versus primary debulking surgery in FIGO stage III-IV epithelial ovarian cancer: A systematic review and meta-analysis.

To compare survival and perioperative outcomes of Primary debulking surgery (PDS) versus neoadjuvant chemotherapy followed by interval debulking surgery (NACT-IDS) in newly diagnosed FIGO stage III-IV ovarian cancer. Primary outcomes were overall survival (OS) and progression-free survival (PFS). MEDLINE, Embase, CENTRAL, Web of Science, Scopus, Cochrane Library, major conference proceedings (inception to July 13, 2025) STUDY SELECTION: Phase-III randomized trials comparing survival outcomes between PDS and NACT-IDS, enrolling adults with newly diagnosed stage III-IV epithelial ovarian, fallopian tube, or primary peritoneal cancer. Following PRISMA, two reviewers independently screened, extracted and assessed risk-of-bias (RoB 1). Random-effects meta-analysis estimated pooled hazard ratios (HRs) for OS/PFS and risk ratios (RRs) for binary endpoints. Heterogeneity was quantified with the I² statistic. PROSPERO (CRD420251056445). Five RCTs (n = 2380 women), including one conference-only report, met criteria. NACT-IDS yielded no difference in OS (HR 1.00; 95 % CI 0.90-1.12; I² = 16 %) and PFS (HR 1.03; 95 % CI 0.92-1.16; I² = 39 %) versus PDS. Grade ≥ 3 perioperative complications were significantly less frequent with NACT-IDS (RR 0.43; 95 % CI 0.25-0.74; I² = 75 %) while CC-0 rates were higher (RR 2.02; 95 % CI 1.26-3.24; I² = 94 %). In FIGO stage III-IV, NACT-IDS achieves survival endpoints similar to PDS, while increasing the likelihood of complete macroscopic resection and reducing severe perioperative morbidity. Upfront surgery in advanced ovarian cancer management should likely be reserved for patients with feasible complete resection and presumed low morbidity.

Exploring the cost-effectiveness of the OSNA method for patients facing endometrial cancer: Insights from a single-institution experience

The one-step nucleic acid amplification (OSNA) method has emerged as a potential alternative to ultrastaging for diagnosing lymph node metastasis. This study aims to assess the cost-effectiveness of the OSNA technique compared to ultrastaging for detecting SLN metastasis in patients with early-stage endometrial cancer (EC). This retrospective, observational, single-center study included 30 patients with EC who underwent surgical treatment. SLN mapping was performed using an intracervical injection of indocyanine green. SLNs were analyzed and classified as negative, as having isolated tumor cells, micrometastases, or macrometastases. The study evaluated and quantified the costs of the OSNA and ultrastaging procedures in euros. A total of 54 lymph nodes were analyzed using both the OSNA and ultrastaging methods. Concordant negativity was identified in 48 cases (89 %), while micrometastases were detected concordantly in 1 case (1.8 %). The cost for a single ultrastaging lymph node analysis, including immunohistochemistry, is approximately € 250, with a total processing time of 2 days. The cost for a single OSNA analysis is approximately € 236, boasting a significantly shorter processing time of 30-40 min. While materials and staff costs are comparable between both techniques, considering time-related expenses, the OSNA method proves to be more cost-effective than ultrastaging (p < 0.001). The OSNA method demonstrates diagnostic accuracy comparable to histopathological examination in detecting lymph node metastases, reinforcing its reliability for lymph node assessment in patients with EC. Our cost analysis reveals that the OSNA method is more cost-effective than ultrastaging when time-related expenses are considered.

Outcomes of low-risk endometrial cancer with isolated tumor cells in the sentinel lymph nodes: a prospective, multi-center, single-arm, observational study (ENDO-ITC study)

It is unclear whether isolated tumor cells (ITCs) in sentinel lymph nodes (SLNs) adversely affect prognosis, especially in low-risk endometrial cancer. In a retrospective study, we showed a worse recurrence-free survival for low-risk endometrial cancer with ITCs than the node-negative group. Our aim is to evaluate whether the likelihood of disease recurrence differs between a prospective cohort of patients with low-risk endometrial cancer with ITCs and an historical cohort with negative SLNs. We hypothesize that patients with low-risk endometrial cancer and ITCs will have a worse recurrence-free survival than patients who are node-negative. This is a prospective, multi-center, single-arm observational study. Consecutive patients with low-risk endometrial cancer with ITCs in the SLNs will be accrued. Observation only will be suggested after surgery. We will include patients with endometrial cancer undergoing pelvic SLN biopsy and ultra-staging with the following characteristics: endometrioid histology, grades 1 to 2, <50% myometrial invasion, without substantial/extensive lympho-vascular space invasion. ITCs in SLNs are defined as tumor cell aggregates ≤0.2 mm or <200 cells. The primary end point is recurrence-free survival, measured from the date of surgery to the date of recurrence, death, or last disease evaluation. With a sample size of 132 women with low-risk endometrial cancer and ITCs, a 1-sided log-rank test achieves 85% power at a 0.05 significance level to detect an HR of 2.1. The expected number of events during the study is 17.3. The study duration will be 60 months: 24 for enrollment and 36 for follow-up. The results are expected in 2029.

The impact of Substantial LYMphovascular space invasion on sentinel lymph nodes status and recurrence in Endometrial Cancer patients: SLYM-EC a multicenter retrospective study

To evaluate the prognostic impact of substantial lymph vascular space invasion (LVSI) on the sentinel lymph node involvement and recurrence rate of patients with apparent uterine-confined endometrial cancer. We enrolled consecutive patients with apparent confined endometrial cancer who underwent surgical staging with sentinel node mapping from 14 European reference centers. LVSI was analyzed semi-quantitatively, according to a 3-tiered scoring system classified as absent, focal, and substantial. Among 2352 eligible patients, 1980 were included in the analysis. Upon final pathology 226 patients (11.4 %) had SLNs involvement. LVSI was diagnosed focal in 152 patients (7.7 %), whereas 357 patients (18.0 %) showed substantial LVSI. Focal or substantial LVSI rate were significantly higher in patients with positive SLNs when compared to patients without SLNs involvement (p < 0.0001). On overall patient-based analysis, the sensitivity, specificity, positive predictive value, and negative predictive value of LVSI for sentinel lymph node metastases were 73 %, 80 %, 32 %, and 96 %, respectively. The 3-year multivariate analysis of recurrence-free survival showed that only the presence of substantial LVSI, and grade 3 disease were associated with relapse. Neither positive sentinel lymph node, deep myometrial infiltration, nor age at surgery were statistically significant. In patients having undergone sentinel node biopsy, positive LVSI demonstrated moderate sensitivity and reasonable specificity in detecting SLN involvement. LVSI positivity does not correlate with nodal involvement. The presence of substantial LVSI remains a strong independent risk factor for recurrence, indicating a role for potential hematogenous dissemination in patients with early-stage disease.

Application of novel algorithm on a retrospective series to implement the molecular classification for endometrial cancer

The study aimed to validate the Betella algorithm, focusing on molecular analyses exclusively for endometrial cancer patients, where molecular classification alters risk assessment based on ESGO/ESTRO/ESP 2020 guidelines. Conducted between March 2021 and March 2023, the retrospective research involved endometrial cancer patients undergoing surgery and comprehensive molecular analyses. These included p53 and mismatch repair proteins immunohistochemistry, as well as DNA sequencing for POLE exonuclease domain. We applied the Betella algorithm to our population and evaluated the proportion of patients in which the molecular analysis changed the risk class attribution. Out of 102 patients, 97 % obtained complete molecular analyses. The cohort exhibited varying molecular classifications: 10.1 % as POLE ultra-mutated, 30.3 % as mismatch repair deficient, 11.1 % as p53 abnormal, and 48.5 % as non-specified molecular classification. Multiple classifiers were present in 3 % of cases. Integrating molecular classification into risk group calculation led to risk group migration in 11.1 % of patients: 7 moved to lower risk classes due to POLE mutations, while 4 shifted to higher risk due to p53 alterations. Applying the Betella algorithm, we can spare the POLE sequencing in 65 cases (65.7 %) and p53 immunochemistry in 17 cases (17.2 %). In conclusion, we externally validated the Betella algorithm in our population. The application of this new proposed algorithm enables assignment of the proper risk class and, consequently, the appropriate indication for adjuvant treatment, allowing for the rationalization of the resources that can be allocated otherwise, not only for the benefit of settings with low resources, but of all settings in general.

Fertility-sparing vs hysterectomy for uterine STUMP: A pragmatic clinical study.

Uterine smooth muscle tumors of uncertain malignant potential (STUMP) are rare neoplasms with unpredictable clinical behavior. Optimal management, particularly in reproductive-aged women, remains controversial, with limited data comparing the safety of fertility-sparing versus hysterectomy. This multicentre retrospective cohort study included women aged 18-85 with histologically confirmed STUMP treated at 17 Italian gynecologic oncology centers from 2010 to 2023. Patients underwent either fertility-sparing surgery (myomectomy or hysteroscopic resection) or definitive surgery (hysterectomy ± salpingo-oophorectomy). Kaplan-Meier and Cox models were used to compare recurrence-free survival (RFS) and overall survival (OS). Median (range) follow-up was 51 (1-291) months. Among 401 women, 106 (26.4 %) received fertility-sparing treatment (mean [± SD] age: 35.3 ± 6.8 years) and 295 (73.6 %) underwent definitive surgery (mean [± SD] age: 47.7 ± 9.2). At total follow-up, recurrence occurred in 12.5 % of patients, predominantly within the pelvis. Median RFS was longer after definitive surgery than after fertility-sparing procedures (50.0 vs 42.5 months; HR 2.39 [95 % CI 1.36-4.19]), although this difference disappeared when benign (leiomyoma) recurrences were excluded (HR 1.74 [95 % CI 0.90-3.34]). At last available follow-up, 97.5 % of patients were alive, with no significant OS difference between treatment groups (HR 0.22 [95 % CI 0.27-1.79]). Outcomes were comparable across menopausal status and concurrent adnexal removal. Definitive surgery reduces recurrence risk, but long-term survival is similarly excellent after fertility-sparing surgery in appropriately selected women with STUMP. Conservative management represents a reasonable option for patients desiring fertility, provided they receive counseling regarding recurrence risk, diagnostic uncertainty, and the need for long-term surveillance.
