Objective: To evaluate the functional outcomes of nerve-sparing surgery for deep infiltrating endometriosis (DIE) with or without posterolateral parametrectomy. Methods:A multicenter, observational, retrospective, cohort study was performed including all symptomatic women who underwent nerve-sparing laparoscopic excision of DIE and preoperative and postoperative assessment of functional outcomes through validated questionnaires between April 2019 and March 2020. Women with posterolateral parametrial DIE (P-group) and women with no parametrial involvement (NP-group) were compared in terms of preoperative and postoperative functional outcomes related to pelvic organs assessed through validated questionnaires (KESS and GIQLI for bowel function, BFLUTS for urinary function, and FSFI for sexual function); pain symptoms at 3-month follow up assessed through an 11-point visual analogue scale (VAS) for dyschezia, dysmenorrhea, dyspareunia and chronic pelvic pain; surgical outcomes; and rate of urinary voiding dysfunction at 3-month follow up.Results: One-hundred patients were included: 69 in the P-group and 31 in the NPgroup. Preoperative and postoperative values of questionnaires, pain symptoms, and postoperative complication rates were comparable between the two groups, except for postoperative dyspareunia and sexual dysfunction, which were statistically higher in the P-group. Only patients in the P-group experienced urinary voiding dysfunction, but no statistical significance was reached (P = 0.173). Conclusion:Posterolateral parametrectomy for DIE appears to be associated with a higher risk of postoperative dyspareunia and sexual dysfunction.

BACKGROUND: An improvement in survival without increasing perioperative morbidity in patients with advanced epithelial ovarian cancer treated with hyperthermic intraperitoneal chemotherapy (HIPEC) after interval debulking surgery (IDS) has been recently demonstrated in a randomized controlled trial. This study was aimed at assessing the feasibility and perioperative outcomes of the use of HIPEC after IDS at a referral cancer center. METHODS: Over the study period, 149 IDSs were performed. Patients who had at least International Federation of Gynecology and Obstetrics stage III disease, with <2.5 mm of residual disease (RD) at the end of surgery and were not participating in clinical trials received HIPEC. Moreover, specific exclusion criteria were considered. These patients were compared with 51 patients with similar clinical characteristics at the same institution and within the same timeframe who did not receive HIPEC. RESULTS: No differences in patient or disease characteristics with the exception of the type of neoadjuvant chemotherapy (P = .002) were found between the 2 groups. As for surgical characteristics, significant differences were found in RD after IDS (P = .007) and in the duration of surgery (P < .001), whereas the bowel resection and diversion rates (P = .583 and P = .213, respectively) and the postoperative intensive care unit and hospital stays (P = .567 and P = .727, respectively) were comparable. The times to start adjuvant chemotherapy were also similar (P = .998). Equally, the rates of any grade of both intraoperative complications (P = .189) and early postoperative complications (P = .238) were superimposable. CONCLUSIONS: In the authors' experience, the addition of HIPEC to IDS is feasible in 35% for the population. This value might increase with changes in the inclusion/exclusion criteria. HIPEC does not increase perioperative complications and does not affect a patient's recovery or time to start adjuvant chemotherapy. HIPEC should be offered to select patients listed for IDS.

Guidelines and expert consensus are lacking on fertility preservation in BRCA mutation carriers and in patients with Lynch syndrome. The safety of fertility preservation in this setting is still a topic of debate and multiple factors need to be carefully considered. The aim of this review was to analyze the reproductive potential of women harboring a genetic mutation affecting the DNA repair system and explore the efficacy and safety of existing fertility preservation strategies in these patients.

The rationale behind the use of hyperthermic intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery is the association between pharmacological activity of chemotherapy delivered to the peritoneal cavity with the enhanced cytotoxic effect of hyperthermia. Data on the efficacy of HIPEC in the primary debulking surgery (PDS) setting are still controversial and limited by the small sample size of most of the studies, the inclusion of different treatment settings and chemotherapy regimens. Among the ongoing prospective trials, only the OVHIPEC-2 trial is investigating exclusively patients submitted to PDS ± HIPEC with cisplatin 100 mg/m 2 and results are expected by 2026. On the interval debulking surgery (IDS) setting high quality data are coming from the result of the OVHIPEC-1 trial, which demonstrated a survival advantage of nearly 4 months in median progression-free survival (PFS) (14.2 months vs. 10.7 months; p = 0.003) and almost 12 months in median overall survival (OS) (45.7 months vs. 33.9 months; p = 0.02) for HIPEC treated patients (cisplatin 100 mg/m 2 ) compared to no-HIPEC group, with comparable morbidity. However, due to some criticisms raised to the results of OVHIPEC-1 trial, the ESMO-ESGO guidelines recommended not to consider HIPEC as standard therapy until results from ongoing randomized control trials (RCTs) are provided. On the contrary, for the National Comprehensive cancer network (NCCN) guidelines HIPEC can be considered at the time of IDS. Similarly, data supporting the role of HIPEC in association with surgery in case of recurrent disease appear to be controversial in terms of patients and selection and intraperitoneal chemotherapy regimen. Indeed, despite the positive results coming from a prospective randomized trial, they appear to be biased by the inclusion of both platinum sensitive and resistant disease and the lack of information on PFS. Those results are in contrast with data coming from another prospective trial, which failed to demonstrate a survival gain of recurrent ovarian cancer patients treated with secondary cytoreductive surgery + HIPEC with carboplatin (800 mg/m 2 for 90 min) compared to women submitted to cytoreduction only. Again, in this subgroup of patients data of ongoing RCTs are awaited to assess the impact on survival of HIPEC administration in case of recurrent disease.

2022-RA-580-ESGO Figure 1 Conclusion This study indicates that DNA methylation analysis in urine samples, self-collected cervicovaginal swabs, and clinician-taken cervical scrapes allows endometrial cancer detection with high accuracy. Our results demonstrate the potential of methylation testing in self-collected material as a novel diagnostic strategy to detect endometrial cancer.

BackgroundThe molecular classification of endometrial cancer revolutionized our knowledge of its biology but so far has not affected our surgical approach. The exact risk of extra-uterine metastasis and hence the type of surgical staging for each of the four molecular subgroups are currently unknown.Primary ObjectiveTo determine the association between molecular classification and disease stage.Study HypothesisEach endometrial cancer molecular subgroup has a specific pattern of spread and this pattern of spread could guide the extent of surgical staging.Trial DesignProspective, multicenter studyMajor Inclusion/Exclusion CriteriaParticipants eligible for inclusion in this study must meet all the following criteria: women ≥18 years with primary endometrial cancer, any histology and stage.Primary EndpointNumber and site of metastasis in each endometrial cancer molecular subgroup.Sample Size1000 patients will be enrolled.Estimated Dates for Completing Accrual and Presenting ResultsThe trial will last 6 years: 4 years of accrual, and 2 years of follow-up of all patients. Results on staging and oncological outcomes are expected in 2027 and 2029, respectively.Trial RegistrationThe study has been accepted by UZ Leuven Ethical Committee. Belg. Reg. nr: B3222022000997
