Presentation and Prognosis of Primary Expansile and Infiltrative Mucinous Carcinomas of the Ovary.

Objective: The aim of the present study was to evaluate evolution and prognosis of mucinous ovarian carcinomas (mOC), with respect to the two invasive patterns: expansile and infiltrative invasion. Methods: This was a descriptive, retrospective, multicenter study conducted in 13 French centres from 1 January 2001 to 31 December 2019. All patients operated on for epithelial ovarian neoplasia of the mucinous type (infiltrative/expansile) were included, whether the surgery was performed immediately or after neoadjuvant chemotherapy. Results: A total of 94 women with mucinous carcinomas were included in the present study. Mucinous tumours were divided into 35 expansile (37%) and 59 infiltrative (63%) mOC. There was a statistically significant difference in early and late stages at initial diagnosis between expansile and infiltrative mOC. None of the expansile mOC showed metastatic lymph nodes, whereas almost a quarter of the infiltrative mOC were metastatic to the pelvic/para-aortic region. There was a clear difference in RFS, in favour of expansile mOC, with 90% survival at 5 years, compared with 60% for infiltrative mOC. Conclusions: Although infiltrative and expansile mOC belong to the same histological family, they present many distinctions in clinical presentation, histological invasion, and disease course.

Risk Factors for Recurrence of Borderline Ovarian Tumours after Conservative Surgery and Impact on Fertility: A Multicentre Study by the Francogyn Group.

INTRODUCTION: Borderline ovarian tumours (BOT) represent 10-20% of epithelial tumours of the ovary. Although their prognosis is excellent, the recurrence rate can be as high as 30%, and recurrence in the infiltrative form accounts for 3% to 5% of recurrences. Affecting, in one third of cases, women of childbearing age, the surgical strategy with ovarian conservation is now recommended despite a significant risk of recurrence. Few studies have focused exclusively on patients who have received ovarian conservative treatment in an attempt to identify factors predictive of recurrence and the impact on fertility. The objective of this study was to identify the risk factors for recurrence of BOT after conservative treatment and the impact on fertility. MATERIAL AND METHODS: This was a retrospective, multicentre study of women who received conservative surgery for BOT between February 1997 and September 2020. We divided the patients into two groups, the "R group" with recurrence and the "NR group" without recurrence. RESULTS: Of 175 patients included, 35 had a recurrence (R group, 20%) and 140 had no recurrence (NR group, 80%). With a mean follow-up of 30 months (IQ 8-62.5), the overall recurrence rate was 20%. Recurrence was BOT in 17.7% (31/175) and invasive in 2.3% (4/175). The mean time to recurrence was 29.5 months (IQ 16.5-52.5). Initial complete peritoneal staging (ICPS) was performed in 42.5% of patients (n = 75). In multivariate analysis, age at diagnosis, nulliparity, advanced FIGO stage, the presence of peritoneal implants, and the presence of a micropapillary component for serous tumours were factors influencing the occurrence of recurrence. The post-surgery fertility rate was 67%. CONCLUSION: This multicentre study is to date one of the largest studies analysing the risk factors for recurrence of BOT after conservative surgery. Five risk factors were found: age at diagnosis, nulliparity, advanced FIGO stage, the presence of implants, and a micropapillary component. Only 25% of the patients with recurrence underwent ICPS. These results reinforce the interest of initial peritoneal staging to avoid ignoring an advanced tumour stage.

Lymphovascular space invasion and estrogen receptor status in high-grade serous ovarian cancer - A multicenter study by the FRANCOGYN group.

BACKGROUND: The aim of this study was to evaluate the impact of Lymphovascular Space Invasion (LVSI) on Overall Survival (OS) and Recurrence-Free Survival (RFS) in patients managed for high-grade serous epithelial ovarian cancer (HGSOC). MATERIALS AND METHODS: Retrospective multicenter study by the FRANCOGYN research group between January 2001 and December 2018. All patients managed for HGSOC and for whom histological slides for the review of LVSI were available, were included. The characteristics of patients with LVSI (LVSI group) were compared to those without LVSI (No LVSI group). A Cox analysis for OS and RFS analysis was performed in all populations. RESULTS: Over the study period, 410 patients were included in the thirteen institutions. Among them, 289 patients had LVSI (33.9%). LVSI was an independent predictive factor for poorer Overall and Recurrence-Free Survival. LVSI affected OS (p<0.001) and RFS (p<0.001), Association of LVSI status and estrogen receptor status (ER) also affected OS and RFS (p = 0.04; p = 0.04 respectively). CONCLUSION: The presence of LVSI in HGSOC has an impact on OS and RFS and should be routinely included in the pathology examination along with ER status.

Adherence to European ovarian cancer guidelines and impact on survival: a French multicenter study (FRANCOGYN).

OBJECTIVE: The primary objective of the study was to validate the European Society for Medical Oncology (ESMO)-European Society of Gynecologic Oncology (ESGO) ovarian cancer guideline as a method of assessing quality of care, and to identify patient characteristics predictive of non-adherence to European guideline care. The secondary objectives were to analyze the evolution of practices over the years and to evaluate heterogeneity between centers. METHODS: This retrospective multicenter cohort study of invasive epithelial ovarian cancer reported to the FRANCOGYN database included data from 12 French centers between January 2000 and February 2017. The main outcome was adherence to ESMO-ESGO guidelines, defined by recommended surgical procedures according to the International Federation of Gynecology and Obstetrics (FIGO) stage and appropriate chemotherapy. Mixed multivariable logistic regression analysis with a random center effect was performed to estimate the probability of adherence to the guidelines. Survival analysis was carried out using the Kaplan-Meier method and a mixed Cox proportional hazards model. RESULTS: 1463 patients were included in the study. Overall, 317 (30%) patients received complete guideline adherent care. Patients received appropriate surgical treatment in 69% of cases, while adequate chemotherapy was administered to 44% of patients. Both patient demographics and disease characteristics were significantly associated with the likelihood of receiving guideline adherent care, such as age, performance status, FIGO stage, and initial burden of disease. In univariate and multivariate survival analysis, adherence to the guidelines was a statistically significant and independent predictor of decreased overall survival. Patients receiving suboptimal care experienced an increased risk of death of more than 100% compared with those treated according to the guidelines (hazard ratio 2.14, 95% confidence interval 1.32 to 3.47, p<0.01). In both models, a significant random center effect was observed, confirming the heterogeneity between centers (p<0.001). CONCLUSIONS: Adherence to ESMO-ESGO guidelines in ovarian cancer was associated with a higher overall survival and may be a useful method of assessing quality of care.

Using a new diagnostic tool to predict lymph node metastasis in advanced epithelial ovarian cancer leads to simple lymphadenectomy decision rules: A multicentre study from the FRANCOGYN group.

OBJECTIVE: The aim of this study was to develop a new diagnostic tool to predict lymph node metastasis (LNM) in patients with advanced epithelial ovarian cancer undergoing primary cytoreductive surgery. MATERIALS AND METHOD: The FRANCOGYN group's multicenter retrospective ovarian cancer cohort furnished the patient population on which we developed a logistic regression model. The prediction model equation enabled us to create LNM risk groups with simple lymphadenectomy decision rules associated with a user-friendly free interactive web application called shinyLNM. RESULTS: 277 patients from the FRANCOGYN cohort were included; 115 with no LNM and 162 with LNM. Three variables were independently and significantly (p<0.05) associated with LNM in multivariate analysis: pelvic and/or para-aortic LNM on CT and/or PET/CT (p<0.00), initial PCI ≥ 10 and/or diaphragmatic carcinosis (p = 0.02), and initial CA125 ≥ 500 (p = 0.02). The ROC-AUC of this prediction model after leave-one-out cross-validation was 0.72. There was no difference between the predicted and the observed probabilities of LNM (p = 0.09). Specificity for the group at high risk of LNM was 83.5%, the LR+ was 2.73, and the observed probability of LNM was 79.3%; sensitivity for the group at low-risk of LNM was 92.0%, the LR- was 0.24, and the observed probability of LNM was 25.0%. CONCLUSION: This new tool may prove useful for improving surgical planning and provide useful information for patients.

Lymphovascular invasion as a criterion for adjuvant chemotherapy for FIGO stage I-IIa clear cell carcinoma, mucinous, low grade serous and low grade endometrioid ovarian cancer.

BACKGROUND: The aim of this study was to evaluate the impact of lymphovascular space invasion (LVSI) on overall survival (OS) and recurrence-free survival (RFS) in patients managed for stage I-IIa clear cell carcinoma, mucinous, low-grade serous and low-grade endometrioid ovarian cancer MATERIAL AND METHODS: Retrospective multicentre study of the research group FRANCOGYN between January 2001 and December 2018. All patients managed for stage I-IIa clear cell carcinoma, mucinous /low grade serous and endometrioid ovarian cancer and for whom the presence of histological slides for the review of LVSI was available, were included. Patient's characteristics with LVSI (LVSI group) were compared to those without LVSI (No LVSI group). A cox analysis for OS and RFS analysis were performed in all population. RESULTS: Over the study period, 133 patients were included in the thirteen institutions. Among them, 12 patients had LVSI (9%). LVSI was an independent predictive factor for poorer Overall and recurrence free survivals. LVSI affected OS (p < 0.001) and RFS (p = 0.0007), CONCLUSION: The presence of LVSI in stage I-IIa clear cell carcinoma, mucinous /low grade serous and endometrioid ovarian cancer has an impact on OS and RFS and should put them at high risk and consider the option of adjuvant chemotherapy.

Lymphovascular space invasion as a prognostic factor of epithelial ovarian cancer: a multicenter study by the FRANCOGYN group.

BACKGROUND: The presence of lymphovascular space invasion (LVSI) is not yet included in international recommendations neither as a prognostic factor nor as a parameter for the decision to use adjuvant chemotherapy in FIGO stage I/IIa ovarian cancer (OC). OBJECTIVE: This study set out to evaluate the impact of LVSI on Overall Survival (OS) and Recurrence-Free Survival (RFS) in patients managed for epithelial OC. DESIGN: Retrospective multicenter study by the research group FRANCOGYN between January 2001 and December 2018. All patients managed for epithelial OC surgery and for whom histological slides for the review of LVSI were available, were included. The characteristics of patients with LVSI (LVSI group) were compared to those without LVSI (No-LVSI group). A Cox analysis for OS and RFS analysis was performed in all the populations. SETTING: French multicenter tertiary care centers RESULTS: Over the study period, 852 patients were included in the 13 institutions. Among them, 289 patients had LVSI (33.9%). There was a significant difference in the distribution of LVSI between early and advanced stages (p < 0.001). LVSI was an independent predictive factor for poorer Overall and Recurrence-Free Survival. LVSI affected OS (p < 0.001) and RFS (p < 0.001), LVSI affected OS and RFS for early stages (p = 0.001; p = 0.001, respectively) and also for advanced stages (p = 0.01; p = 0.009, respectively). CONCLUSION: The presence of LVSI in epithelial ovarian epithelial tumors has an impact on OS and RFS and should be included in the routine pathology examination to adapt therapeutic management, especially for women in the early stages of the disease.

Does Time-to-Chemotherapy after Primary Complete Macroscopic Cytoreductive Surgery Influence Prognosis for Patients with Epithelial Ovarian Cancer? A Study of the FRANCOGYN Group.

To determine if the time-to-chemotherapy (TTC) after primary macroscopic complete cytoreductive surgery (CRS) influences recurrence-free survival (RFS) and overall survival (OS) in patients with epithelial ovarian cancer (EOC). We conducted an observational multicenter retrospective cohort analysis of women with EOC treated from September 2006 to November 2016 in nine institutions in France (FRANCOGYN research group) with maintained EOC databases. We included women with EOC (all FIGO stages) who underwent primary complete macroscopic CRS prior to platinum-based adjuvant chemotherapy. Two hundred thirty-three patients were included: 73 (31.3%) in the early-stage group (ESG) (FIGO I-II), and 160 (68.7%) in the advanced-stage group (ASG) (FIGO III-IV). Median TTC was 43 days (36-56). The median OS was 77.2 months (65.9-106.6). OS was lower in the ASG when TTC exceeded 8 weeks (70.5 vs. 59.3 months, p = 0.04). No impact on OS was found when TTC was below or above 6 weeks (78.5 and 66.8 months, respectively, p = 0.25). In the whole population, TTC had no impact on RFS or OS. None of the factors studied were associated with an increase in TTC. Chemotherapy should be initiated as soon as possible after CRS. A TTC greater than 8 weeks is associated with poorer OS in patients with advanced stage EOC.

Prognosis impact of posttreatment pelvic MRI in patients treated for stage IB2-IIB cervical cancer with chemoradiation therapy.

OBJECTIVES: To evaluate the performances of systematic posttreatment pelvic magnetic resonance imaging (PPMRI) in predicting prognosis of patients treated with chemoradiation therapy (CRT) for locally advanced cervical cancer (LACC). MATERIALS AND METHODS: Multi-institutional data from 216 patients presenting FIGO IB2-IIB cervical cancer for which PPMRI was performed following CRT were retrospectively reviewed. Incomplete response was defined as the identification of persistent lesion on PPMRI. Primary endpoints were patients' 5-year recurrence free (RFS) and overall (OS) survivals. Secondary endpoint was the identification of residual histologic disease on hysterectomy specimens when completion surgery was performed. RESULTS: PPMRI identified an incomplete response in 102 (47.2%) cases. A 70% or more reduction in tumor size on PPMRI was identified as the best predictive cut-off for recurrence (37.7% sensitivity and 78.7% specificity) and death (50% sensitivity and 77.9% specificity) with significant impact on those risks (HRa: 0.42; 95%CI: 0.23-0.77 and HRa: 0.18; 95%CI: 0.06-0.50, respectively). Completion hysterectomy was performed in 117 (54.4%) cases, with histologic residual disease in 55 (47.4%). PPMRI demonstrated 74.5% sensitivity and 50.8% specificity in predicting residual disease. Although survival of patients with complete response at PPMRI was not impacted by completion hysterectomy, it significantly increased 5-year RFS and OS of those with incomplete response: 38.7% vs. 65.3% (p < 0.001) and 63% vs. 82.9% (p = 0.038), respectively. CONCLUSION: A 70% or more reduction of in tumor size on PPMRI following CRT in patients with LACC is predictive of RFS and OS. PPMRI could help triaging patients who could benefit from completion hysterectomy.

Impact on Prognosis of the Surgical Route, Laparoscopy or Laparotomy, for the Surgical Staging of Early Stage Ovarian Cancer-A Study from the FRANCOGYN Group.

BACKGROUND AND OBJECTIVE: according to the latest ESMO-ESGO recommendations, laparotomy is the standard surgical approach to treat and stage patients with presumed early stage epithelial ovarian cancer (EOC). A few studies have investigated the efficacy and the safety of laparoscopy for the staging of early stage EOC, and this question is still in the center of debates. Recurrence-free survival (RFS) and overall survival (OS) benefits of the minimally invasive surgery (MIS) have still to be specified. The aim of this multicenter and retrospective study is to assess the survival outcomes of laparoscopic staging in comparison with laparotomic staging for patients presenting with an early stage EOC. METHODS: data of patients with early stage EOC (FIGO I-IIA) who underwent primary surgery between 2000 and 2018 were extracted from the FRANCOGYN database. OS and RFS of these two groups, constituted according to the surgical route, were compared using Log rank test. RESULTS: of the 144 patients included, 107 patients underwent laparotomy and 37 underwent laparoscopy for a staging purpose. The median follow-up was 36.0 months (18.0 to 58.0). For the laparoscopy and the laparotomy group, the median follow-up period was 24 (11.0 to 50.0) and 42.0 (24.0 to 66.0) months, respectively, (p < 0.001). Tumor recurrence occurred in 33 (23%) patients: 2 (5.4%) in the laparoscopy group and 31 (29%) in the laparotomy group (p = 0.08). The OS rate at 5 years was 97.3% after laparoscopy and 79.8% after laparotomy (p = 0.19). CONCLUSIONS: there is no difference associated with the laparoscopic approach for the staging of early stage EOC on RFS and OS in comparison with laparotomy. MIS may be proposed as a safe and adequate alternative to laparotomy when performed by well-trained surgeons.

Recurrence Pattern of Cervical Cancer Based on the Platinum Sensitivity Concept: A Multi-Institutional Study from the FRANCOGYN Group.

The standard of care for patients with advanced cervical cancer (ACC) includes platinum-based chemotherapy. The concept of platinum sensitivity is a major prognostic factor for patients with ovarian cancer. The aim of this study was to validate the applicability of the platinum sensitivity concept to ACC patients, and to estimate its prognostic interest in terms of overall survival (OS) and pattern of recurrence (location, timing). Data of women with histologically proven FIGO 2019 stages IB3-IV ACC, treated between May 2000 and November 2017 with platinum-based regimens, were retrospectively abstracted from 12 institutions from the FRANCOGYN Group. Respective 3-year OSs were 52% (95% CI: 40.8%-66.8%), 21.6% (95% CI: 12.6%-37.2%), and 14.6% (95% CI: 4.2%-50.2%), in case of recurrence <6 months, between 6 and 17 months, and ≥18 months (p < 0.001). Risk of metastatic or multisite recurrence was significantly higher in case of recurrence <6 months, and risk of local or isolated infradiaphragmatic nodal recurrence was significantly higher in case of recurrence >18 months (p < 0.001). In multivariate analysis, platinum sensitivity status was a strong prognostic factor for OS after recurrence, independent of histological grade, lympho-vascular space involvement, final lymph node status, and treatment. Platinum sensitivity status may help to classify patients in three prognostic subgroups for OS after recurrence, and appears to be a strong prognostic factor correlated to the pattern of recurrence.

Accuracy of peritoneal carcinomatosis extent diagnosis by initial FDG PET CT in epithelial ovarian cancer: A multicentre study of the FRANCOGYN research group.

INTRODUCTION: Peritoneal carcinomatosis extent in ovarian cancer is difficult to evaluate by imaging techniques even though it determines the surgical complexity and survival. The aim of this study was to estimate the accuracy of 2-[18F]-fluoro-2-deoxy-d-glucose (FDG)-PET CT (Positron-emission tomography coupled with Computerised Tomography) performed before any treatment, in the diagnosis of the extent of peritoneal carcinomatosis. We compared these results to per-operative observations/ histology samples obtained during surgery (laparotomy/ laparoscopy). MATERIAL AND METHODS: All women managed for an epithelial ovarian cancer between 1st January 2000 and 30th June 2016 were included if they had a FDG PET CT, before initiation of any treatment (neoadjuvant chemotherapy or frontline cytoreductive surgery). The extent of disease on histology samples from cytoreductive surgery/observations during exploratory laparoscopy were compared with the PET CT results. RESULTS: Over the study period, 980 women were managed for epithelial ovarian cancer, among them 90 (9.2 %) had a PET CT before any treatment. The diagnostic reliability of an ovarian lesion was 67.8 %, a colon lesion was 61.25 %, a small intestine lesion was 50.6 %, an epiploic lesion was 41.7 %, a pelvic ganglionic invasion was 62.9 % and a paraortic lymph node invasion was 61.5 %. PET CT was less effective than a standard CT examination. CONCLUSION: PET CT is not the most effective imaging examination to estimate the extent of peritoneal carcinomatosis during the initial management of an epithelial ovarian cancer.

Revisiting the management of term breech presentation: a proposal for overcoming some of the controversies.

BACKGROUND: The debate surrounding the management of term breech presentation has excessively focused on the mode of delivery. Indeed, a steady decline in the rate of vaginal breech delivery has been observed over the last three decades, and the soundness of the vaginal route was seriously challenged at the beginning of the 2000s. However, associations between adverse perinatal outcomes and antenatal risk factors have been observed in foetuses that remain in the breech presentation in late gestation, confirming older data and raising the question of the role of these antenatal risk factors in adverse perinatal outcomes. Thus, aspects beyond the mode of delivery must be considered regarding the awareness and adequate management of such situations in term breech pregnancies. MAIN BODY: In the context of the most recent meta-analysis and with the publication of large-scale epidemiologic studies from medical birth registries in countries that have not abruptly altered their criteria for individual decision-making regarding the breech delivery mode, the currently available data provide essential clues to understanding the underlying maternal-foetal conditions beyond the delivery mode that play a role in perinatal outcomes, such as foetal growth restriction and gestational diabetes mellitus. In view of such data, an accurate evaluation of these underlying conditions is necessary in cases of persistent term breech presentation. Timely breech detection, estimated foetal weight/growth curves and foetal/maternal well-being should be considered along with these possible antenatal risk factors; a thorough analysis of foetal presentation and an evaluation of the possible benefit of external cephalic version and pelvic adequacy in each specific situation of persistent breech presentation should be performed. CONCLUSION: The adequate management of term breech pregnancies requires screening and the efficient identification of breech presentation at 36 weeks of gestation, followed by thorough evaluations of foetal weight, growth and mobility, while obstetric history, antenatal gestational disorders and pelvis size/conformation are considered. The management plan, including external cephalic version and follow-up based on the maternal/foetal condition and potentially associated disorders, should be organized on a case-by-case basis by a skilled team after the woman is informed and helped to make a reasoned decision regarding delivery route.

Ovarian Cancer in the Elderly: Time to Move towards a More Logical Approach to Improve Prognosis-A Study from the FRANCOGYN Group.

BACKGROUND AND OBJECTIVE: Elderly and/or frail women with ovarian cancer are often undertreated. The aim of the study is to compare the effects of age and frailty on surgical approaches, postoperative complications, and prognosis in elderly women with ovarian cancer. METHODS: A retrospective multicenter study of women ≥70 years were treated for ovarian cancer at seven French university hospitals between 2007 and 2015. RESULTS: Of the 1119 women treated for ovarian cancer during the study period, 147 were ≥70 years and had complete data. Of these women, 65 were aged 70-74 years, and 82 were aged ≥75 years. Overall, 77% of the younger women (49/65) received optimal treatment compared with 51% (40/82) of the older women (p = 0.018). Women ≥75 years underwent fewer bowel resections (32% vs. 67%, p < 0.001) and experienced fewer postoperative complications (22.6% vs. 38.9%, p < 0.001); 53.2% of the women in this age group were treated by primary surgery or surgery only. These women also received more chemotherapy with platinum only (15% [9/56] vs. 2% [1/57], p = 0.007) and less bevacizumab (9% [5/56] vs. 32% [18/57], p = 0.003). Patients with greater frailty (a modified Charlson Comorbidity Index [mCCI] score >3) had a five-year survival rate of 30% versus 62% for those with a score ≤3 (p < 0.001). CONCLUSIONS: Surgeons modify their approach to treating ovarian cancer in women ≥75 years probably to reduce immediate postoperative complications. The prognosis is significantly worse in patients with greater frailty. Improvements to the sequence of treatments administered, with priority given to neoadjuvant chemotherapy in patients with greater frailty, could help increase the number of women who receive optimal treatment and improve their prognosis.

Isolated lymph node recurrence in epithelial ovarian cancer: Recurrence with better prognosis?

INTRODUCTION: The aim of this study was to compare overall survival (OS) between women with isolated lymph node recurrence (ILNR) and those with isolated peritoneal localization of recurrence (ICR), in patients managed for epithelial ovarian cancer. METHODS: Data from 1508 patients with ovarian cancer were collected retrospectively from1 January 2000 to 31 December 2016, from the FRANCOGYN database, pooling data from 11 centres specialized in ovary treatment. Median overall survival was determined using the Kaplan-Meier method. Univariate and multivariate analyses were performed to define prognostic factors of overall survival. Patients included had a first recurrence defined as ILNR or ICR during their follow up. RESULTS: 79 patients (5.2 %) presented with ILNR, and 247 (16.4 %) patients had isolated carcinomatosis recurrence. Complete lymphadenectomy was performed more frequently in the ILNR group vs. the ICR group (67.1 % vs. 53.4 %, p = 0.004) and the number of pelvic lymph nodes involved was higher (2.4 vs. 1.1, p = 0.008). The number of involved pelvic LN was an independent predictor of ILNR (OR = 1.231, 95 % CI [1.074-1.412], p = 0.0024). The 3-year and 5-year OS rates in the ILNR group were 85.2 % and 53.7 % respectively, compared to 68.1 % and 46.8 % in patients with ICR. There was no significant difference in terms of OS after initial diagnosis (p = 0.18). 3- year and 5-year OS rates after diagnosis of recurrence were 62.6 % and 15.6 % in the ILNR group, and 44 % and 15.7 % in patients with ICR (p = 0.21). CONCLUSION: ILNR does not seem to be associated with a better prognosis in terms of OS.

Management and Survival of Elderly and Very Elderly Patients with Ovarian Cancer: An Age-Stratified Study of 1123 Women from the FRANCOGYN Group.

Elderly women with ovarian cancer are often undertreated due to a perception of frailty. We aimed to evaluate the management of young, elderly and very elderly patients and its impact on survival in a retrospective multicenter study of women with ovarian cancer between 2007 to 2015. We included 979 women: 615 women (62.8%) <65 years, 225 (22.6%) 65-74 years, and 139 (14.2%) ≥75 years. Women in the 65-74 years age group were more likely to have serous ovarian cancer (p = 0.048). Patients >65 years had more >IIa FIGO stage: 76% for <65 years, 84% for 65-74 years and 80% for ≥75 years (p = 0.033). Women ≥75 years had less standard procedures (40% (34/84) vs. 59% (104/177) for 65-74 years and 72% (384/530) for <65 years (p < 0.001). Only 9% (13/139) of women ≥75 years had an Aletti score >8 compared with 16% and 22% for the other groups (p < 0.001). More residual disease was found in the two older groups (30%, respectively) than the younger group (20%) (p < 0.05). Women ≥75 years had fewer neoadjuvant/adjuvant cycles than the young and elderly women: 23% ≥75 years received <6 cycles vs. 10% (p = 0.003). Univariate analysis for 3-year Overall Survival showed that age >65 years, FIGO III (HR = 3.702, 95%CI: 2.30-5.95) and IV (HR = 6.318, 95%CI: 3.70-10.77) (p < 0.001), residual disease (HR = 3.226, 95%CI: 2.51-4.15; p < 0.001) and lymph node metastasis (HR = 2.81, 95%CI: 1.91-4.12; p < 0.001) were associated with lower OS. Women >65 years are more likely to have incomplete surgery and more residual disease despite more advanced ovarian cancer. These elements are prognostic factors for women's survival regardless of age. Specific trials in the elderly would produce evidence-based medicine and guidelines for ovarian cancer management in this population.

Prognostic value of posttreatment FEDG-PET imaging following combined chemoradiation therapy in locally advanced cervical cancer.

OBJECTIVES: To evaluate the performances of posttreatment FEDG-PET to predict the prognosis of patients treated with concurrent chemoradiotherapy (CT/RT) for locally advanced cervical cancer. MATERIALS AND METHODS: The medical records of 131 patients treated in 9 French academic institutions for IB2-IIB cervical cancer and for which a posttherapy FEDG-PET was performed were reviewed. All patients received CT/RT, possibly completed with vaginal brachytherapy (VBT) and completion surgery. Posttreatment FEDG-PET was performed within 3 months after completion of CT/RT or VBT. Incomplete metabolic response (IMR) was defined as the persistence of FEDG uptake. RESULTS: An IMR was identified in 44 (33.6 %) cases. IMR was associated with higher risk of recurrence (aHR = 2.8; 95 %CI: 1.3-5.7; p = 0.006) and death (aHR = 4.5 ;95 %CI: 1.4-13.8; p = 0.009). Completion surgery was performed in 61 (46.9 %) patients with histologic cervical residual disease identified in 31 (50.8 %). FEDG-PET sensitivity and specificity in predicting cervical residual disease following CT/RT was 48.4 % (95 %CI: 30.8-66) and 80 % (95 %CI: 65.7-94.3), respectively. CONCLUSIONS: In patients treated with CT/RT for locally advanced cervical cancer, despite limited performances to predict cervical residual disease, posttreatment FEDG-PET is predictive of patients' prognosis and long-term outcome.

Patients with stage IV epithelial ovarian cancer: understanding the determinants of survival.

BACKGROUND: The most appropriate management for patients with stage IV ovarian cancer remains unclear. Our objective was to understand the main determinants associated with survival and to discuss best surgical management. METHODS: Data of 1038 patients with confirmed ovarian cancer treated between 1996 and 2016 were extracted from maintained databases of 7 French referral gynecologic oncology institutions. Patients with stage IV diseases were selected for further analysis. The Kaplan-Meier method was used to estimate the survival distribution. A Cox proportional hazards model including all the parameters statistically significant in univariable analysis, was used to account for the influence of multiple variables. RESULTS: Two hundred and eight patients met our inclusion criteria: 65 (31.3%) never underwent debulking surgery, 52 (25%) underwent primary debulking surgery (PDS) and 91 (43.8%) neoadjuvant chemotherapy and interval debulking surgery (NACT-IDS). Patients not operated had a significantly worse overall survival than patients that underwent PDS or NACT-IDS (p < 0.001). In multivariable analysis, three factors were independent predictors of survival: upfront surgery (HR 0.32 95% CI 0.14-0.71, p = 0.005), postoperative residual disease = 0 (HR 0.37 95% CI 0.18-0.75, p = 0.006) and association of Carboplatin and Paclitaxel regimen (HR 0.45 95% CI 0.25-0.80, p = 0.007). CONCLUSIONS: Presence of distant metastases should not refrain surgeons from performing radical procedures, whenever the patient is able to tolerate. Maximal surgical efforts should be done to minimize residual disease as it is the main determinant of survival.

Recommendations for the surgical management of gynecological cancers during the COVID-19 pandemic - FRANCOGYN group for the CNGOF.

INTRODUCTION: In the context of the COVID-19 pandemic, specific recommendations are required for the management of patients with gynecologic cancer. MATERIALS AND METHOD: The FRANCOGYN group of the National College of French Gynecologists and Obstetricians (CNGOF) convened to develop recommendations based on the consensus conference model. RESULTS: If a patient with a gynecologic cancer presents with COVID-19, surgical management should be postponed for at least 15 days. For cervical cancer, radiotherapy and concomitant radiochemotherapy could replace surgery as first-line treatment and the value of lymph node staging should be reviewed on a case-by-case basis. For advanced ovarian cancers, neoadjuvant chemotherapy should be preferred over primary cytoreduction surgery. It is legitimate not to perform hyperthermic intraperitoneal chemotherapy during the COVID-19 pandemic. For patients who are scheduled to undergo interval surgery, chemotherapy can be continued and surgery performed after 6 cycles. For patients with early stage endometrial cancer of low and intermediate preoperative ESMO risk, hysterectomy with bilateral adnexectomy combined with a sentinel lymph node procedure is recommended. Surgery can be postponed for 1-2 months in low-risk endometrial cancers (FIGO Ia stage on MRI and grade 1-2 endometrioid cancer on endometrial biopsy). For patients of high ESMO risk, the MSKCC algorithm (combining PET-CT and sentinel lymph node biopsy) should be applied to avoid pelvic and lumbar-aortic lymphadenectomy. CONCLUSION: During the COVID-19 pandemic, management of a patient with cancer should be adapted to limit the risks associated with the virus without incurring loss of chance.

Cervical cancer recurrence: Proposal for a classification based on anatomical dissemination pathways and prognosis.

INTRODUCTION: Precise definitions of recurrences and optimal treatment strategy are yet to be clearly defined among patients with cervical cancer (CC). The purpose of this study was to develop a reproducible classification of CC recurrence. MATERIEL AND METHODS: Data of women with FIGO stages I-IV CC treated between January 2000 and January 2015 were retrospectively abstracted from nine French institutions. We proposed a rTNM classification for recurrence: locoregional (rT), nodal (rN), or distant organ (rM). According to rTNM prognosis, we then defined a rSTAGE classification (I, II, IIIA, IIIB, IVA, IVB). RESULTS: Among the 1028 women treated for FIGO stages I-IV CC during the study period, 216 recurrences were observed (21%). The 3-year survival after recurrence was 38.8%, with a median time to recurrence of 9 months (95% CI, 30.9-48.7). A trend for a lower 3-year survival after recurrence was observed in women with multiple-site vs single-site recurrence (p = 0.1). Among the women in the rT group, a difference in 3-year survival after recurrence was found between rT1 single site, rT2 single site and rT3 single site (p = 0.02). The 3-year survival after recurrence was 69.1%, 49.2%, 37.5%, 34.2%, 23.1% and 24.4% for rStage I, II, IIIA, IIIB, IVA and IVB, respectively (p = 0.007). CONCLUSION: rTNM classifications and rSTAGE are discriminatory and allow all recurrence modalities to be classified.
