IntroductionEndometriosis affects 5–10% of women during reproductive years, with a 20–30% incidence among those with infertility. Deep infiltrating endometriosis (DIE) affects 10–15% of women of childbearing age and 50% of infertile women. When hormonal therapy and conservative surgery prove ineffective, total hysterectomy with or without bilateral salpingo-oophorectomy may be the ultimate therapeutic option. Laparoscopic surgery is the gold standard for treating endometriosis, offering effective disease eradication, safety, reduced pain, shorter hospital stay and faster recovery compared with laparotomy. However, patients undergoing total laparoscopic hysterectomy with DIE have higher risks of complications and organ damage, particularly urinary tract damage. Robot-assisted laparoscopic hysterectomy has emerged as a promising alternative, with a significantly lower conversion rate than total laparoscopic hysterectomy in patients with endometriosis. This study evaluates the safety and efficacy of robot-assisted total laparoscopic hysterectomy (RATLH) versus total laparoscopic hysterectomy (TLH) in the management of DIE. We hypothesise that robot-assisted laparoscopic hysterectomy will result in fewer complications and better outcomes compared with total laparoscopic hysterectomy in DIE patients.Methods and analysisThe ENDORAS trial is a prospective, multicentre, open-label, randomised controlled trial conducted in French reference hospitals specialising in endometriosis surgery. A total of 224 adult women patients will be enrolled in this study if they have DIE with adenomyosis, and without digestive tract involvement as confirmed by MRI. Participants will be randomised to undergo either RATLH or TLH. The primary outcome will be the intraoperative and postoperative complication rates, classified according to the Clavien-Dindo classification (grade 2 or above) at the 3-month postoperative follow-up. Among the secondary outcomes, we will evaluate the quality of life using various questionnaires, including the Endometriosis Health Profile-30, the Short Form-306 and the Female Sexual Function Index.Ethics and disseminationThe ENDORAS trial will be conducted in accordance with the International Council on Harmonization Good Clinical Practice guidelines. All trial documents and procedures have been reviewed and approved by the Ethics Committee Ile de France II (approval ID number: 24.01408.000300). Informed consent will be obtained during the preoperative check-up by the operating gynaecologist. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media, print media and the internet.Trial registration numberNCT06445179.

Background Infertility associated with endometriosis can be explained by several non-exclusive mechanisms. The oocyte plays a crucial role in determining embryonic competence and this is particularly relevant for in vitro fertilization (IVF) outcomes. According to some authors, the morphology of oocytes could also be a non-invasive marker of oocyte quality. The aim of this study was to evaluate the relationship between endometriosis and oocyte morphology after controlled ovarian stimulation for intracytoplasmic sperm injection (ICSI) on a large oocyte cohort. Methods Single-center comparative retrospective study in the academic In Vitro Fertilization (IVF) unit of the Lille University Hospital. A total of 596 women treated for IVF-ICSI with ejaculated spermatozoa for sperm alterations were included. They were classified as endometriosis (n = 175) or control groups (n = 401). The morphological evaluation of 2,016 mature oocytes from 348 cycles of patients with endometriosis was compared with that of 4,073 mature oocytes from 576 control cycles. The main outcome measures were Average Oocyte Quality Index (AOQI) and metaphase II oocyte morphological scoring system (MOMS). Comparison of groups was carried out by a mixed linear model and by a generalized estimation equation model with a \"patient\" random effect to consider that a patient might have several attempts. Results No difference in AOQI and MOMS scores was found between endometriosis and control women ( adjusted p  = 0.084 and 0.053, respectively). In case of endometriosis, there were significantly fewer metaphase II oocytes retrieved, embryos obtained, grade 1 embryos and number of cumulative clinical pregnancies compared to controls. In the endometriosis group, endometriosis surgery was associated with a reduced number of mature oocytes retrieved, and the presence of endometrioma(s) was associated with some abnormal oocyte shapes. Nevertheless, no difference concerning the AOQI and MOMS scores was found in these subgroups. Conclusion Endometriosis does not have a negative impact on oocytes’ morphology in IVF-ICSI. Trial registration On December 16, 2019, the Institutional Review Board of the Lille University Hospital gave unrestricted approval for the anonymous use of all patients’ clinical, hormonal and ultrasound records (reference DEC20150715-0002).

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.

Background This study aimed to assess the interest in robot-assisted laparoscopy for deep infiltrating endometriosis and to investigate the perioperative results. Methods From November 2008 to April 2012, 164 women with stage 4 endometriosis who underwent robot-assisted laparoscopy (da Vinci Intuitive Surgical System) were included by to eight international participating clinical centers. This study evaluated the procedures performed, the duration of the intervention, the complications, the recurrence, and the impact on fertility. Results The average operative time was 180 min. The main complications were laparotomy ( n  = 1, 0.6 %), sutured bowel injury ( n  = 2, 1.2 %), transfusion for a 2,300-ml bleed ( n  = 1), prolonged urinary catheterization ( n  = 1, 0.6 %), ureter-bladder anastomotic leak ( n  = 1, 0.6 %), and ureteral fistula after ureterolysis ( n  = 2, 1.2 %). The reoperation rate was 1.8 % ( n  = 3). The mean follow-up period was 10.2 months. A full recovery was experienced by 86.7 % (98/113) of the patients. After surgery, 41.2 % (42/102) of the patients had a desire for pregnancy, and 28.2 % (11/39) of them became pregnant. Conclusion This study analyzed the largest series of robot-assisted laparoscopies for deep infiltrating endometriosis published in the literature. No increase in surgical time, blood loss, or intra- or postoperative complications was observed. The interest in robot-assisted laparoscopy for deep infiltrating endometriosis seems to be promising.

Background The prognostic impact of surgical paraaortic staging remains unclear in patients with locally advanced cervical cancer (LACC). The objective of our study was to evaluate the survival impact of surgical staging in patients with LACC and no evidence of paraaortic lymph node (PALN) metastasis on pre-operative imaging work-up. Methods Data of 1447 patients with cervical cancer treated between 1996 and 2016 were extracted from maintained databases of 10 French University hospitals. Patients with locally advanced disease (IB2 or more) treated by concurrent chemoradiation therapy (CRT) and no evidence of paraaortic metastasis on pre-operative imaging work-up were selected for further analysis. The Kaplan–Meier method was used to estimate the survival distribution. A Cox proportional hazards model was used to account for the influence of multiple variables. Results Six hundred and forty-seven patients were included, 377 (58.3%) with surgical staging and 270 (41.7%) without, with a mean follow up of 38.1 months (QI 13.0–56.0). Pathologic analysis revealed positive lymph nodes in 47 patients (12.5%). In multivariate model analysis, surgical staging remained an independent prognostic factor for DFS (OR 0.64, CI 95% 0.46–0.89, p = 0.008) and OS (OR 0.43, CI 95% 0.27–0.68, p < 0.001). The other significant parameter in multivariate analysis for both DFS and OS was treatment by intracavitary brachytherapy (OR respectively of 0.7 (0.5–1.0) and 0.6 (0.4–0.9), p < 0.05). Conclusion Nodal surgical staging had an independent positive impact on survival in patients with LACC treated with CRT with no evidence of metastatic PALN on imaging.

Background Recent studies have challenged radical procedures for less extensive surgery in selected patients with early-stage cervical cancer at low risk of parametrial invasion. Our objective was to identify a subgroup of patients at low risk of parametrial invasion among women having undergone surgical treatment. Methods Data of 1447 patients with cervical cancer treated between 1996 and 2016 were extracted from maintained databases of 10 French University hospitals. Patients with early-stage (IA2–IIA) disease treated by radical surgery including hysterectomy and trachelectomy, 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 univariate analysis, was used to account for the influence of multiple variables. Results Out of the 263 patients included for analysis, on final pathology analysis 28 (10.6%) had parametrial invasion and 235 (89.4%) did not. Factors significantly associated with parametrial invasion on multivariate analysis were: age > 65 years, tumor > 30 mm in diameter measured by MRI, lymphovascular space invasion (LVSI) on pathologic analysis. Among the 235 patients with negative pelvic lymph nodes, parametrial disease was seen in only 7.6% compared with 30.8% of those with positive pelvic nodes (p < 0.001). In a subgroup of patients presenting tumors < 30 mm, negative pelvic status and no LVSI, the risk of parametrial invasion fell to 0.6% (1/173 patients). Conclusion Our analysis suggests that there is a subgroup of patients at very low risk of parametrial invasion, potentially eligible for less radical procedures.

Objective To evaluate the feasibility of nerve-sparing radical hysterectomy in early cervical cancer by robot-assisted laparoscopy and atonic bladder rate. Methods This was a retrospective study with consecutive patients in three gynecological oncology departments. Patients with <2 cm cervical cancer had nerve-sparing radical hysterectomy by robot-assisted laparoscopy and pelvic lymphadenectomy. Two days after surgery, we systematically removed the Foley bladder catheter. Results The median (range) age and body mass index of the 30 patients were 44 (33–68) years and 23.9 (17.7–39.4) kg/m 2 , respectively. The median (range) tumor diameter at the time of surgery was 13 (4–38) mm. The median (range) operative time, blood loss, and number of pelvic lymph nodes (any common iliac lymph nodes) were 305 (180–405) min, 100 (30–1,500) ml, and 18 (7–28). The overall complication rate was 52.3 %, of which 6.7 % atonic bladder. Twenty-eight patients (93.3 %) were discharged 2 days after surgery with spontaneous voiding and no residual urine >100 ml. Conclusions Nerve-sparing radical hysterectomy by robot-assisted laparoscopy is feasible in early cervical cancer (<2 cm). A total of 93.3 % of the patients were discharged 2 days after surgery with spontaneous voiding. The next step would be a prospective study with objective urodynamic investigations.

The European Society of Gynaecological Oncology, the European Society of Human Reproduction and Embryology, and the European Society for Gynaecological Endoscopy jointly developed clinically relevant and evidence-based guidelines focusing on key aspects of fertility-sparing strategies and follow-up of patients with cervical cancers, ovarian cancers, and borderline ovarian tumours. The developmental process of these guidelines is based on a systematic literature review and critical appraisal involving an international multidisciplinary development group consisting of 25 experts from relevant disciplines (ie, gynaecological oncology, oncofertility, reproductive surgery, endoscopy, imaging, conservative surgery, medical oncology, and histopathology). Before publication, the guidelines were reviewed by 121 independent international practitioners in cancer care delivery and patient representatives. The guidelines comprehensively cover oncological aspects of fertility-sparing strategies during the initial management, optimisation of fertility results and infertility management, and the patient's desire for future pregnancy and beyond.

Background: The purpose of this study was to develop a nomogram to predict ‘poor prognosis recurrence’ (PPR) in women treated for endometrial cancer (EC). Methods: The data of 861 women who received primary surgical treatment between January 2001 and December 2013 were abstracted from a prospective multicenter database. Data were randomly split into two sets: training and validation with a predefined 2/3 ratio. A Cox proportional hazards multivariate model of selected prognostic features was performed in the training cohort ( n =574) to develop a nomogram predicting PPRs. The nomogram was validated in the validation cohort of 287 patients. Results: In the training cohort, 82 (14.3%) developed subsequent PPR. Age, histologic type and grade, lymphovascular space invasion status, FIGO stage, and nodal staging (SLN±pelvic and/or para-aortic lymphadenectomy) were independently associated with subsequent PPR. The nomogram showed an area under the receiver operating characteristic curve (AUC) of 0.82 (95% confidence interval (CI), 0.73–0.89) in the training set. The validation set showed a good discrimination with an AUC of 0.75 (95% CI, 0.65–0.83). Conclusions: We have developed a robust tool that is able to predict subsequent PPRs in women with FIGO I–III EC.
