Management challenges in low-grade serous ovarian cancer with a BRCA mutation

An international worldwide retrospective cohort observational study comparing primary cytoreductive surgery with neoadjuvant chemotherapy and interval cytoreductive surgery in patients with carcinoma of the ovary, fallopian tubes, and peritoneum (SUROVA trial)

Currently, a lively debate exists within the scientific community regarding the most suitable procedure for treating stages IIIB-IVB carcinoma of the ovary, fallopian tubes, and peritoneum. The options under most consideration are primary cytoreductive surgery or neoadjuvant chemotherapy followed by interval cytoreductive surgery. To compare overall survival at 5 years in patients who underwent primary cytoreductive surgery versus neoadjuvant chemotherapy and interval cytoreductive surgery for stage IIIB-IVB ovarian cancer STUDY HYPOTHESIS: The treatment with primary cytoreductive surgery results in superior patient survival compared with neoadjuvant chemotherapy followed by interval cytoreductive surgery. This is a multicenter, retrospective cohort observational study. Data will be collected from patients undergoing surgery in hospitals worldwide. Two arms will be compared: primary cytoreductive surgery and neoadjuvant chemotherapy followed by interval cytoreductive surgery. Patients must have suspected or histologically confirmed International Federation of Gynecology and Obstetrics (FIGO) stages IIIB-IVB ovarian, peritoneal, or fallopian tube cancers. They must have undergone primary surgery or first course of neoadjuvant chemotherapy between January 1, 2018 and December 31, 2019. Based on all available information before the surgery (primary or interval), the patient must have been considered completely resectable. Overall survival at 5 years from the first treatment (chemotherapy in the case of neoadjuvant chemotherapy and cytoreduction in the case of primary cytoreductive surgery). An estimated total of 5000 patients will be enrolled in the study. March 2025 TRIAL REGISTRATION: NCT06223763.

Global practice patterns of sentinel lymph node biopsy in endometrial cancer: a survey from the European Network of Young Gynecologic Oncologists (ENYGO)

This survey aimed to evaluate trends in sentinel lymph node (SLN) biopsy for endometrial cancer among members of the European Society of Gynecologic Oncology (ESGO) and the International Gynecologic Cancer Society (IGCS). We conducted an online cross-sectional survey among gynecologic oncologists over 40 years of age consisting of 30 questions. It was distributed to ESGO and IGCS members via Survey Monkey and Qualtrics between September and December 2022. Surveys were excluded in the analysis if >50% of questions were incomplete. Statistical analysis, performed with SPSS version 27.0. A total of 302 (70.2%) of 430 participants completed the survey, with 159 (52.6%) affiliated with ESGO and 143 (47.4%) with IGCS. The majority were male 206 (68.2%), and 170 (56.3%) were based in Europe. Most respondents (n = 261, 86.4%) were certified gynecologic oncologists. Indocyanine green was the most common tracer used (n = 234, 77.5%), with higher rates of blue dye injections among IGCS respondents (p = .002). The predominant injection volume was 4 cm This study showed significant variations in SLN biopsy practices for endometrial cancer, underscoring the need for global standardization through harmonized guidelines, consistent training, and international collaboration to improve staging accuracy and patient outcomes.

Determinants of adjuvant radiotherapy in early-stage cervical cancer: a retrospective analysis of the SUCCOR cohort

This study aimed to describe the patterns of adjuvant therapy use within the SUCCOR cohort, a large retrospective analysis comparing disease-free survival following minimally invasive versus open surgery in early-stage cervical cancer. Furthermore, to assess the factors associated with the indication for adjuvant radiotherapy after radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB (≤4cm) cervical cancer. A retrospective analysis was performed using the SUCCOR study database. We investigated patients with FIGO 2009 stage IB1, node-negative cervical cancer at final pathology. Univariate and multi-variable logistic regression were performed to determine factors associated with the administration of adjuvant radiation therapy. The study included a total of 572 patients. Of these, 340 patients (59.4%) did not receive adjuvant radiotherapy, including 45 (13.2%) who met the Sedlis criteria. Conversely, among the 232 patients (40.6%) who received adjuvant radiotherapy, 132 (56.9%) did not meet Sedlis criteria. In the univariate logistic regression, factors associated with adjuvant radiotherapy included tumor size >2 cm (p< .001), lymphovascular space invasion (p < .001) and a tumor grade G3 (vs G1-G2, p .01). Furthermore, the probability of receiving adjuvant radiotherapy was higher for patients with deep stromal invasion (p < .001), and with intermediate stromal invasion (p < .001) in comparison to those with superficial stromal invasion. At multiple logistic regression, open approach (odds ratio [OR] 1.63, p =.01) and G3 tumor grade (OR 1.64, p= .01) were independently associated with the administration of adjuvant radiotherapy. In addition, the presence of Sedlis criteria was associated with a 4 times higher probability of having adjuvant radiotherapy (OR 4.44, p < .001). While the Sedlis criteria should guide post-operative radiotherapy administration, we observed a significant variation in post-operative adjuvant treatment among institutions involved in the SUCCOR study. A call for a standardized recommendation of adjuvant radiation therapy is needed.

Accuracy of pre-operative tumor size assessment compared to final pathology and frequency of adjuvant treatment in patients with FIGO 2018 stage IB2 cervical cancer

The primary aim of our study was to compare tumor size assessment by pre-operative evaluation (physical examination and/or imaging) with tumor size on final pathology. As a secondary outcome, we evaluated the rate of adjuvant treatment in patients who underwent radical hysterectomy whose tumor size was ≥3 cm on final pathology. Patient details were collected from three separate databases: the University of Texas MD Anderson Cancer Center Radical Hysterectomy Database, the SUCCOR Study Group Database, and the Multi-institutional Database LATAM (encompassing Latin America and Europe). Patients with International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IB2 cervical cancer on pre-operative evaluation (physical examination or imaging) who underwent radical hysterectomy with a therapeutic intent were included. Any histological subtype, any tumor grade, and pre-operative evaluation with clinical evaluation and/or imaging (ultrasound, MRI, CT, or PET/CT) was considered. A total of 675 patients met eligibility criteria (SUCCOR=350, LATAM=250, MD Anderson=75). The median age was 46 years (range 22-82) and the median body mass index was 25.6 kg/m Our study showed that there is a high concordance between tumor size assessment by physical examination and MRI, as well as estimates of measurement by MRI and final pathology. In addition, we noted that the majority of patients with FIGO 2018 stage IB2 received adjuvant therapy after radical hysterectomy.

Assessing minimally invasive simple hysterectomy in low risk cervical cancer: set up for the LASH trial

After the publication of the Laparoscopic Approach to Cervical Cancer (LACC) trial, open surgery has become the standard approach for radical hysterectomy in early stage cervical cancer. Recent studies assessed the role of a non-radical approach in low risk cervical cancer and showed no survival difference compared with radical hysterectomy. However, there is a gap in knowledge regarding the oncologic outcomes of minimally invasive simple hysterectomy in low risk cervical cancer. This review offers an overview of the current evidence on the role of the minimally invasive approach in low risk cervical cancer and raises the need for a new clinical trial in this setting.

SUCCOR morbidity: complications in minimally invasive versus open radical hysterectomy in early cervical cancer

The aim of this study was to compare the incidence of intra-operative and post-operative complications in open and minimally invasive radical hysterectomy for patients with early-stage cervical cancer. Data were collected from the SUCCOR database of 1272 patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO), 2009) who underwent radical hysterectomy in Europe between January 2013 and December 2014. We reviewed the duration of the surgeries, estimated blood loss, length of hospital stay, intra-operative and post-operative complications. The inclusion criteria were age ≥18 years and histologic type (squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma). Pelvic MRI confirming a tumor diameter ≤4 cm with no parametrial invasion and a pre-operative CT scan, MRI, or positron emission tomography CT demonstrating no extra-cervical metastatic disease were mandatory. Outcomes of interest were any grade >3 adverse events, intra-operative adverse events, post-operative adverse events, length of hospital stay, length of operation, and blood loss. The study included 1156 patients, 633 (54%) in the open surgery group and 523 (46%) in the minimally invasive surgery group. Median age was 46 years (range 18-82), median body mass index 25 kg/m Our study showed that there was no significant difference in the overall incidence of intra-operative and post-operative complications between minimally invasive radical hysterectomy and the open approach.

Ultrasound examination, MRI, or ROMA for discriminating between inconclusive adnexal masses as determined by IOTA Simple Rules: a prospective study

To determine the best second-step approach for discriminating benign from malignant adnexal masses classified as inconclusive by International Ovarian Tumour Analysis Simple Rules (IOTA-SR). Single-center prospective study comprising a consecutive series of patients diagnosed as having an adnexal mass classified as inconclusive according to IOTA-SR. All women underwent Risk of Ovarian Malignancy Algorithm (ROMA) analysis, MRI interpreted by a radiologist, and ultrasound examination by a gynecological sonologist. Cases were clinically managed according to the result of the ultrasound expert examination by either serial follow-up for at least 1 year or surgery. Reference standard was histology (patient was submitted to surgery if any of the tests was suspicious) or follow-up (masses with no signs of malignancy after 12 months were considered benign). Diagnostic performance of all three approaches was calculated and compared. Direct cost analysis of the test used was also performed. Eighty-two adnexal masses in 80 women (median age 47.6 years, range 16 to 73 years) were included. Seventeen patients (17 masses) were managed expectantly (none had diagnosis of ovarian cancer after at least 12 months of follow-up) and 63 patients (65 masses) underwent surgery and tumor removal (40 benign and 25 malignant tumors). Sensitivity and specificity for ultrasound, MRI, and ROMA were 96% and 93%, 100% and 81%, and 24% and 93%, respectively. The specificity of ultrasound was better than that for MRI (p=0.021), and the sensitivity of ultrasound was better than that for ROMA (p<0.001), sensitivity was better for MRI than for ROMA (p<0.001) and the specificity of ROMA was better than that for MRI (p<0.001). Ultrasound evaluation was the most effective and least costly method as compared with MRI and ROMA. In this study, ultrasound examination was the best second-step approach in inconclusive adnexal masses as determined by IOTA-SR, but the findings require confirmation in multicenter prospective trials.

European Society of Gynaecological Oncology guidelines for the peri-operative management of advanced ovarian cancer patients undergoing debulking surgery

The European Society of Gynaecological Oncology (ESGO) developed and established for the first time in 2016, and updated in 2020, quality indicators for advanced ovarian cancer surgery to audit and improve clinical practice in Europe and beyond. As a sequela of the continuous effort to improve oncologic care in patients with ovarian cancer, ESGO issued in 2018 a consensus guidance jointly with the European Society of Medical Oncology addressing in a multidisciplinary fashion 20 selected key questions in the management of ovarian cancer, ranging from molecular pathology to palliation in primary and relapse disease. In order to complement the above achievements and consolidate the promoted systemic advances and surgical expertise with adequate peri-operative management, ESGO developed, as the next step, clinically relevant and evidence-based guidelines focusing on key aspects of peri-operative care and management of complications as part of its mission to improve the quality of care for women with advanced ovarian cancer and reduce iatrogenic morbidity. To do so, ESGO nominated an international multidisciplinary development group consisting of practicing clinicians and researchers who have demonstrated leadership and expertise in the care and research of ovarian cancer (18 experts across Europe). To ensure that the guidelines are evidence based, the literature published since 2015, identified from a systematic search, was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 117 independent international practitioners in cancer care delivery and patient representatives.

ESGO/ISUOG/IOTA/ESGE Consensus Statement on pre-operative diagnosis of ovarian tumors

The European Society of Gynaecological Oncology (ESGO), the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG), the International Ovarian Tumour Analysis (IOTA) group, and the European Society for Gynaecological Endoscopy (ESGE) jointly developed clinically relevant and evidence-based statements on the pre-operative diagnosis of ovarian tumors, including imaging techniques, biomarkers, and prediction models. ESGO/ISUOG/IOTA/ESGE nominated a multidisciplinary international group, including expert practising clinicians and researchers who have demonstrated leadership and expertise in the pre-operative diagnosis of ovarian tumors and management of patients with ovarian cancer (19 experts across Europe). A patient representative was also included in the group. To ensure that the statements were evidence-based, the current literature was reviewed and critically appraised. Preliminary statements were drafted based on the review of the relevant literature. During a conference call, the whole group discussed each preliminary statement and a first round of voting was carried out. Statements were removed when a consensus among group members was not obtained. The voters had the opportunity to provide comments/suggestions with their votes. The statements were then revised accordingly. Another round of voting was carried out according to the same rules to allow the whole group to evaluate the revised version of the statements. The group achieved consensus on 18 statements. This Consensus Statement presents these ESGO/ISUOG/IOTA/ESGE statements on the pre-operative diagnosis of ovarian tumors and the assessment of carcinomatosis, together with a summary of the evidence supporting each statement.

Radical hysterectomy in early cervical cancer in Europe: characteristics, outcomes and evaluation of ESGO quality indicators

Comprehensive updated information on cervical cancer surgical treatment in Europe is scarce. To evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database. The SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified. The mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m In this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.

SUCCOR study: an international European cohort observational study comparing minimally invasive surgery versus open abdominal radical hysterectomy in patients with stage IB1 cervical cancer

Minimally invasive surgery in cervical cancer has demonstrated in recent publications worse outcomes than open surgery. The primary objective of the SUCCOR study, a European, multicenter, retrospective, observational cohort study was to evaluate disease-free survival in patients with stage IB1 (FIGO 2009) cervical cancer undergoing open vs minimally invasive radical hysterectomy. As a secondary objective, we aimed to investigate the association between protective surgical maneuvers and the risk of relapse. We obtained data from 1272 patients that underwent a radical hysterectomy by open or minimally invasive surgery for stage IB1 cervical cancer (FIGO 2009) from January 2013 to December 2014. After applying all the inclusion-exclusion criteria, we used an inverse probability weighting to construct a weighted cohort of 693 patients to compare outcomes (minimally invasive surgery vs open). The first endpoint compared disease-free survival at 4.5 years in both groups. Secondary endpoints compared overall survival among groups and the impact of the use of a uterine manipulator and protective closure of the colpotomy over the tumor in the minimally invasive surgery group. Mean age was 48.3 years (range; 23-83) while the mean BMI was 25.7 kg/m Minimally invasive surgery in cervical cancer increased the risk of relapse and death compared with open surgery. In this study, avoiding the uterine manipulator and using maneuvers to avoid tumor spread at the time of colpotomy in minimally invasive surgery was associated with similar outcomes to open surgery. Further prospective studies are warranted.

Patterns of recurrence after laparoscopic versus open abdominal radical hysterectomy in patients with cervical cancer: a propensity-matched analysis

Recent evidence has suggested that laparoscopic radical hysterectomy is associated with an increased risk of recurrence in comparison with open abdominal radical hysterectomy. The aim of our study was to identify patterns of recurrence after laparoscopic and open abdominal radical hysterectomy for cervical cancer. This a retrospective multi-institutional study evaluating patients with recurrent cervical cancer after laparoscopic and open abdominal surgery performed between January 1990 and December 2018. Inclusion criteria were: age ≥18 years old, radical hysterectomy (type B or type C), no recurrent disease, and clinical follow-up >30 days. The primary endpoint was to evaluate patterns of first recurrence following laparoscopic and open abdominal radical hysterectomy. The secondary endpoint was to estimate the effect of the primary surgical approach (laparoscopy and open surgery) in post-recurrence survival outcomes (event-free survival and overall survival). In order to reduce possible confounding factors, we applied a propensity-matching algorithm. Survival outcomes were estimated using the Kaplan-Meier model. A total of 1058 patients were included in the analysis (823 underwent open abdominal radical hysterectomy and 235 patients underwent laparoscopic radical hysterectomy). The study included 117 (14.2%) and 35 (14.9%) patients who developed recurrent cervical cancer after open or laparoscopic surgery, respectively. Applying a propensity matched comparison (1:2), we reduced the population to 105 patients (35 vs 70 patients with recurrence after laparoscopic and open radical hysterectomy). Median follow-up time was 39.1 (range 4-221) months and 32.3 (range 4-124) months for patients undergoing open and laparoscopic surgery, respectively. Patients undergoing laparoscopic radical hysterectomy had shorter progression-free survival than patients undergoing open abdominal surgery (HR 1.98, 95% CI 1.32 to 2.97; p=0.005). Patients undergoing laparoscopic radical hysterectomy were more likely to develop intrapelvic recurrences (74% vs 34%; p<0.001) and peritoneal carcinomatosis (17% vs 1%; p=0.005) than patients undergoing open surgery. Patients undergoing laparoscopic radical hysterectomy are at higher risk of developing intrapelvic recurrences and peritoneal carcinomatosis. Further evidence is needed in order to corroborate our findings.

SUCCOR quality: validation of ESGO quality indicators for surgical treatment of cervical cancer

To evaluate whether compliance with European Society of Gynaecological Oncology (ESGO) surgery quality indicators impacts disease-free survival in patients undergoing radical hysterectomy for cervical cancer. In this retrospective cohort study, 15 ESGO quality indicators were assessed in the SUCCOR database (patients who underwent radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage 2009 IB1, FIGO 2018 IB1, and IB2 cervical cancer between January 2013 and December 2014), and the final score ranged between 0 and 16 points. Centers with more than 13 points were classified as high-quality indicator compliance centers. We constructed a weighted cohort using inverse probability weighting to adjust for the variables. We compared disease-free survival and overall survival using Cox proportional hazards regression analysis in the weighted cohort. A total of 838 patients were included in the study. The mean number of quality indicators compliance in this cohort was 13.6 (SD 1.45). A total of 479 (57.2%) patients were operated on at high compliance centers and 359 (42.8%) patients at low compliance centers. High compliance centers performed more open surgeries (58.4% vs 36.7%, p<0.01). Women who were operated on at centers with high compliance with quality indicators had a significantly lower risk of relapse (HR=0.39; 95% CI 0.25 to 0.61; p<0.001). The association was reduced, but remained significant, after further adjustment for conization, surgical approach, and use of manipulator surgery (HR=0.48; 95% CI 0.30 to 0.75; p=0.001) and adjustment for adjuvant therapy (HR=0.47; 95% CI 0.30 to 0.74; p=0.001). Risk of death from disease was significantly lower in women operated on at centers with high adherence to quality indicators (HR=0.43; 95% CI 0.19 to 0.97; p=0.041). However, the association was not significant after adjustment for conization, surgical approach, use of manipulator surgery, and adjuvant therapy. Patients with early cervical cancer who underwent radical hysterectomy in centers with high compliance with ESGO quality indicators had a lower risk of recurrence and death.

SUCCOR Risk: Design and Validation of a Recurrence Prediction Index for Early-Stage Cervical Cancer

Abstract Objective Based on the SUCCOR study database, our primary objective was to identify the independent clinical pathological variables associated with the risk of relapse in patients with stage IB1 cervical cancer who underwent a radical hysterectomy. Our secondary goal was to design and validate a risk predictive index (RPI) for classifying patients depending on the risk of recurrence. Methods Overall, 1116 women were included from January 2013 to December 2014. We randomly divided our sample into two cohorts: discovery and validation cohorts. The test group was used to identify the independent variables associated with relapse, and with these variables, we designed our RPI. The index was applied to calculate a relapse risk score for each participant in the validation group. Results A previous cone biopsy was the most significant independent variable that lowered the rate of relapse (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.17–0.60). Additionally, patients with a tumor diameter &gt;2 cm on preoperative imaging assessment (OR 2.15, 95% CI 1.33–3.5) and operated by the minimally invasive approach (OR 1.61, 95% CI 1.00–2.57) were more likely to have a recurrence. Based on these findings, patients in the validation cohort were classified according to the RPI of low, medium, or high risk of relapse, with rates of 3.4%, 9.8%, and 21.3% observed in each group, respectively. With a median follow-up of 58 months, the 5-year disease-free survival rates were 97.2% for the low-risk group, 88.0% for the medium-risk group, and 80.5% for the high-risk group (p &lt; 0.001). Conclusion Previous conization to radical hysterectomy was the most powerful protective variable of relapse. Our risk predictor index was validated to identify patients at risk of recurrence.

SUCCOR cone study: conization before radical hysterectomy

To evaluate disease-free survival of cervical conization prior to radical hysterectomy in patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009). A multicenter retrospective observational cohort study was conducted including patients from the Surgery in Cervical Cancer Comparing Different Surgical Aproaches in Stage IB1 Cervical Cancer (SUCCOR) database with FIGO 2009 IB1 cervical carcinoma treated with radical hysterectomy between January 1, 2013, and December 31, 2014. We used propensity score matching to minimize the potential allocation biases arising from the retrospective design. Patients who underwent conization but were similar for other measured characteristics were matched 1:1 to patients from the non-cone group using a caliper width ≤0.2 standard deviations of the logit odds of the estimated propensity score. We obtained a weighted cohort of 374 patients (187 patients with prior conization and 187 non-conization patients). We found a 65% reduction in the risk of relapse for patients who had cervical conization prior to radical hysterectomy (hazard ratio (HR) 0.35, 95% confidence interval (CI) 0.16 to 0.75, p=0.007) and a 75% reduction in the risk of death for the same sample (HR 0.25, 95% CI 0.07 to 0.90, p=0.033). In addition, patients who underwent minimally invasive surgery without prior conization had a 5.63 times higher chance of relapse compared with those who had an open approach and previous conization (HR 5.63, 95% CI 1.64 to 19.3, p=0.006). Patients who underwent minimally invasive surgery with prior conization and those who underwent open surgery without prior conization showed no differences in relapse rates compared with those who underwent open surgery with prior cone biopsy (reference) (HR 1.94, 95% CI 0.49 to 7.76, p=0.349 and HR 2.94, 95% CI 0.80 to 10.86, p=0.106 respectively). In this retrospective study, patients undergoing cervical conization before radical hysterectomy had a significantly lower risk of relapse and death.

ESGO/ESTRO quality indicators for radiation therapy of cervical cancer

The European Society of Gynaecological Oncology (ESGO) has previously defined and established a list of quality indicators for the surgical treatment of cervical cancer. As a continuation of this effort to improve overall quality of care for cervical cancer patients across all aspects, ESGO and the European SocieTy for Radiotherapy and Oncology (ESTRO) initiated the development of quality indicators for radiation therapy of cervical cancer. To develop a list of quality indicators for radiation therapy of cervical cancer that can be used to audit and improve clinical practice by giving to practitioners and administrators a quantitative basis to improve care and organizational processes, notably for recognition of the increased complexity of modern external radiotherapy and brachytherapy techniques. Quality indicators were based on scientific evidence and/or expert consensus. The development process included a systematic literature search for identification of potential quality indicators and documentation of scientific evidence, consensus meetings of a group of international experts, an internal validation process, and external review by a large international panel of clinicians (n=99). Using a structured format, each quality indicator has a description specifying what the indicator is measuring. Measurability specifications are detailed to define how the quality indicators will be measured in practice. Targets were also defined for specifying the level which each unit or center should be aiming to achieve. Nineteen structural, process, and outcome indicators were defined. Quality indicators 1-6 are general requirements related to pretreatment workup, time to treatment, upfront radiation therapy, and overall management, including active participation in clinical research and the decision making process within a structured multidisciplinary team. Quality indicators 7-17 are related to treatment indicators. Quality indicators 18 and 19 are related to patient outcomes. This set of quality indicators is a major instrument to standardize the quality of radiation therapy in cervical cancer. A scoring system combining surgical and radiotherapeutic quality indicators will be developed within an envisaged future ESGO accreditation process for the overall management of cervical cancer, in an effort to support institutional and governmental quality assurance programs.

SUROVA study: global real-world treatment strategies and mortality risk prediction in advanced ovarian cancer

This study aimed to compare 5-year overall survival between primary debulking surgery and neoadjuvant chemotherapy followed by interval surgery in patients with stage IIIB to IVB epithelial ovarian cancer, using global real-world data. Secondary objectives included evaluation of progression-free survival and the influence of race, post-operative complications, and residual disease. SUROVA is a retrospective, international cohort study involving patients treated between 2018 and 2019 across 174 centers in 55 countries. Patients underwent primary surgery or received neoadjuvant chemotherapy followed by interval surgery, per institutional protocols. Propensity score matching was based on 7 baseline variables: age, race, Eastern Cooperative Oncology Group performance status at diagnosis, CA125 level at diagnosis, FIGO (International Federation of Gynecology and Obstetrics) stage IV disease, presence of ascites, and final tumor grade. Cox regression models with time-dependent effects and interaction terms were applied. A clinical risk calculator was developed and internally validated. A total of 3286 patients had a mean age of 60.0 years (SD 12); 2978 (90.6%) had high-grade serous carcinoma, and 795 (24.7%) presented with FIGO stage IV disease. A total of 1666 patients (50.7%) underwent primary cytoreductive surgery, and 1620 (49.3%) received neoadjuvant chemotherapy. The median follow-up duration was 43.8 months (interquartile range; 22.6-59.3). After propensity score matching (n=1524), overall survival was similar between groups (67.2 vs 65.0 months; HR 1.002, 95% CI 0.85 to 1.18, p=.98). Outcomes differed by ethnicity, residual disease, and post-operative complications. Post-operative complications (28%) significantly worsened survival (66 vs 46 months; HR 1.5, 95% CI 1.2 to 1.9, p<.001), especially among patients undergoing primary surgery (73 vs 46 months; HR 1.85, 95% CI 1.43 to 2.37, p<.001). The most favorable outcomes were observed among patients with primary surgery, complete resection, and no complications, with median overall survival not reached (HR 1.25, 95% CI 1.12 to 1.40, p<.001). Although overall survival was similar between groups, treatment effects differed by ethnicity, residual disease, and complications. Post-operative complications were associated with significantly worse survival, particularly among patients undergoing primary surgery, while the best outcomes were achieved in those who had primary surgery with complete resection and no complications.

Prognostic value of isolated tumor cells in sentinel lymph nodes in intermediate-risk endometrial cancer: results from an international, multi-institutional study

This study assessed oncologic outcomes of patients with intermediate-risk endometrioid endometrial cancer and isolated tumor cells (ITC) (≤0.2 mm or ≤200 cells) in sentinel lymph nodes (SLNs). Patients with SLN-ITC diagnosed between 2012 and 2019 were identified from 19 centers worldwide, while SLN-negative patients were identified at Mayo Clinic, Rochester between 2014 and 2018. Only patients with endometrioid endometrial cancer and intermediate-risk factors (low-grade endometrioid histology and myometrial invasion ≥50%; high-grade endometrioid histology and myometrial invasion <50%) were included. Oncologic outcomes were evaluated by grouping patients according to prognostic factors: SLN-ITC and lymphovascular space invasion (LVSI). SLN-ITC patients with post-operative observation or vaginal brachytherapy (VB) alone were compared with similar node-negative patients. Of the 166 patients included, those with simultaneous presence of SLN-ITC and LVSI were at higher risk of non-vaginal recurrence (HR 3.73 [95% CI 1.17 to 11.84], p = .01) compared with patients who were node-negative with no LVSI. Among the 122 patients (28 SLN-ITC, 94 node-negative) who underwent post-operative observation or VB alone, 1 isolated vaginal recurrence was documented in a node-negative patient, while non-vaginal recurrence occurred in 3 of 28 (10.7%) SLN-ITC and 7 of 94 (7.4%) node-negative patients. The median follow-up was 2.4 years (interquartile range; 1.8-3.0) among the remaining 25 ITC patients and 2.8 years (interquartile range; 0.8-4.2) among the remaining 87 node-negative patients. There was no difference in non-vaginal recurrence-free survival (SLN-ITC: 87.3% [95% CI 74.7% to 100.0%] vs node-negative: 82.2% [95% CI 69.1% to 97.9%], p = .46) or overall survival (SLN-ITC: 76.4% [95% CI 54.3 to 100.0] vs node-negative: 84.5% [95% CI 75.0 to 95.2], p = .28) between the 2 cohorts. In patients with endometrioid endometrial cancer and intermediate-risk factors (including patients who received chemotherapy/external beam radiotherapy), the combination of SLN-ITC and LVSI was associated with worse prognosis compared with patients with no risk factors or only 1 risk factor. In the sub-group of patients who received post-operative observation or VB alone, SLN-ITC did not worsen prognosis relative to node-negative patients.

SUCCOR 10 years: a decade's perspective on radical hysterectomy outcomes in cervical cancer.

Interest in long-term outcomes of radical hysterectomy for cervical cancer has increased, especially after the LACC trial findings, which showed worse outcomes for minimally invasive surgery. However, limited information is available on 10-year oncological outcomes, particularly, recurrence and survival. The primary objective of this study was to analyze the 10-year oncological outcomes of patients with International Federation of Gynecology and Obstetrics 2009 stage IB1 cervical cancer treated with radical hysterectomy performed via minimally invasive or open approaches. This retrospective, multi-center, observational study updates the data from the SUCCOR cohort. Patients diagnosed between January 2013 and December 2014 with tumors ≤4 cm without extra-cervical metastasis and treated with radical hysterectomy as the primary treatment were included, and a 10-year follow-up after surgery was successfully conducted. A total of 556 patients were analyzed. The median age was 46 years (range; 18-82). The most common final International Federation of Gynecology and Obstetrics 2009 stage was IB1, 474 patients (85%), and the most common histology was squamous carcinoma, 376 patients (67.6%). The 5-year disease-free survival was 93%, and the 10-year disease-free survival was 90%. The overall survival was 97% at 5 years and 89% at 10 years. During follow-up, 9% (n = 49) of patients experienced recurrences, 78% (n = 38) within the first 5 years. Comparing surgical approaches, 10-year disease-free survival was 92% for minimally invasive surgery and 88% for open surgery (p = .12). Similarly, 10-year overall survival was 92% for minimally invasive surgery and 88% for open surgery (p = .12). Post-recurrence disease-specific survival was 47% at 60 months and 39% at 96 months. The 2-year survival after recurrence was 80% for late recurrences (>5 years) versus 69% for early recurrences. The overall survival after radical hysterectomy at 5-years was 97% in patients with early-stage cervical cancer. The recurrence rate at 10 years was 9%. No differences in 10-year survival were observed between the surgical approaches.

SENECA study: staging endometrial cancer based on molecular classification

Management of endometrial cancer is advancing, with accurate staging crucial for guiding treatment decisions. Understanding sentinel lymph node (SLN) involvement rates across molecular subgroups is essential. To evaluate SLN involvement in early-stage (International Federation of Gynecology and Obstetrics 2009 I-II) endometrial cancer, considering molecular subtypes and new European Society of Gynaecological Oncology (ESGO) risk classification. The SENECA study retrospectively reviewed data from 2139 women with stage I-II endometrial cancer across 66 centers in 16 countries. Patients underwent surgery with SLN assessment following ESGO guidelines between January 2021 and December 2022. Molecular analysis was performed on pre-operative biopsies or hysterectomy specimens. Among the 2139 patients, the molecular subgroups were as follows: 272 (12.7%) p53 abnormal (p53abn, 1191 (55.7%) non-specific molecular profile (NSMP), 581 (27.2%) mismatch repair deficient (MMRd), 95 (4.4%) POLE mutated (POLE-mut). Tracer diffusion was detected in, at least one side, in 97.2% of the cases; with a bilateral diffusion observed in 82.7% of the cases. By ultrastaging (90.7% of the cases) or one-step nucleic acid amplification (198 (9.3%) of the cases), 205 patients were identified with affected sentinel lymph nodes, representing 9.6% of the sample. Of these, 139 (67.8%) had low-volume metastases (including micrometastases, 42.9%; and isolated tumor cells, 24.9%) while 66 (32.2%) had macrometastases. Significant differences in SLN involvement were observed between molecular subtypes, with p53abn and MMRd groups having the highest rates (12.50% and 12.40%, respectively) compared with NSMP (7.80%) and POLE-mut (6.30%), (p=0.004); (p53abn, OR=1.69 (95% CI 1.11 to 2.56), p=0.014; MMRd, OR=1.67 (95% CI 1.21 to 2.31), p=0.002). Differences were also noted among ESGO risk groups (2.84% for low-risk patients, 6.62% for intermediate-risk patients, 21.63% for high-intermediate risk patients, and 22.51% for high-risk patients; p<0.001). Our study reveals significant differences in SLN involvement among patients with early-stage endometrial cancer based on molecular subtypes. This underscores the importance of considering molecular characteristics for accurate staging and optimal management decisions.

Ovarian cancer during fertility follow-up

Artificial intelligence for single-omics in ovarian cancer: a methodological review

Ovarian cancer is a leading cause of cancer-related mortality among women, with poor prognosis and limited survival in advanced stages. The integration of artificial intelligence with omics data offers new opportunities to enhance the diagnosis, prognosis, and treatment of this disease. This narrative review synthesizes evidence from 14 studies published between 2021 and 2024 that applied artificial intelligence to genomic, transcriptomic, metabolomic, micro-biomic, and epigenomic data sets in patients with epithelial ovarian cancer. These studies explored artificial intelligence models for disease detection, chemotherapy response prediction, and genetic risk stratification. Despite promising results (eg, high classification accuracy and area under the curve values in some models), significant limitations were observed, including small sample sizes, retrospective and single-center designs, and inconsistent use of validation data sets. The review highlights critical methodological considerations such as data preprocessing, normalization, and feature selection, which substantially influence model performance and reproducibility. Although classification models (eg, deep learning, random forest, and support vector machines) were most commonly used, regression approaches were less frequent and under-used, despite their value for modeling continuous outcomes such as survival time. Overall, artificial intelligence-based approaches demonstrate great potential for advancing personalized medicine in ovarian cancer. However, future research must prioritize larger, multi-center, prospective studies with robust validation strategies and improved model interpretability to enable clinical implementation.

Modified Tumor-free Techniques Operation to Cervical Cancer

The goal of this clinical trial is to learn if laparoscopic radical hysterectomy incorporating modified tumor-free techniques (LRH-MTF) works to treat FIGO stage IB2 cervical cancer as good as abdominal radical hysterectomy (ARH). It will also learn about the safety of LRH-MTF. The main questions it aims to answer are: Does LRH-MTF achieve a non-inferior disease-free survival rate at 4.5 years post - operation compared to ARH? What complications do patients have during and after the operation when receiving LRH-MTF? Researchers will compare LRH-MTF to ARH to see if LRH-MTF works no worse than ARH in treating FIGO stage IB2 cervical cancer. Participants will: 1. Undergo either LRH-MTF or ARH as assigned by randomization. 2. Visit the hospital for follow-up according to the study schedule for various examinations including blood tests, imaging studies, and assessment of complications. 3. Complete quality-of-life questionnaires such as EORTC QLQ-C30, QLQ-CX24, FSFI, and FSDS-R at baseline (pre-operation) and specific time points during the follow - up period (post-operation 6 months, 1 year, 2 years, 3 years, 4.5 years).

Prognostic Value of Conization and Negative HPV After Conization in AIS and Early Stage Cervical Cancer

In women with cervical cancer -Squamous cell carcinoma, Adeno carcinoma, Adeno-squamous carcinoma or AIS we want to examine prospectively: 1. Examine if negative HR-HPV after conization to the HR-HPV the women had before conization has a high prognostic value for no residual tumor in the final pathology. 2. To examine if conization in women with cervical tumor up to Stage I B 2 (FIGO 2018) is corelated with better prognosis.
