RESUMO
OBJECTIVE: To investigate the prevalence and patterns of social media use among gynecologic oncologists for professional and academic purposes. METHODS: A prospective online survey between November and December 2022 targeted gynecologic oncology practitioners (gynecologic oncologists, surgical oncologists, medical oncologists, radiation/clinical oncologists, and onco-pathologists/pathologists). The survey, distributed via various social media platforms, included 40 questions to capture qualitative and quantitative data on social media use. RESULTS: Of 131 respondents from 32 countries, 106 (80.9%) were gynecologic oncologists and affiliated with academic institutions (84.7%). Facebook (n=110, 83.9%), Twitter (n= 108, 82.4%), and Instagram (n=100, 76.3%) were the most used platforms. Respondents used social media to stay updated (n=101, 77.1%), network (n=97, 74%), learn about conferences and webinars (n=97, 74%), and engage in academic discussions (n=84, 64.1%). Following the COVID-19 pandemic, 100/129 (77.5%) reported increased social media use. However, only 32 (24.4%) used it to connect with patients, and concerns were raised about privacy and the need for separate professional and personal accounts. A quarter of respondents hesitated to share their opinions on social media due to the fear of controversy, with 26 (20%) experiencing cyberbullying, yet 120/130 (92.3%) believed it enabled junior professionals to express their views. Concerns about differentiating valid content, information reliability, and the professional perception of sourcing knowledge from social media were noted. Gender, age, specialty, and income level influenced patterns of social media use, with variations in preferences for platforms, content engagement, and purposes, highlighting a complex landscape of social media interaction among gynecologic oncologists. CONCLUSION: While the use of social media among gynecologic oncologists is prevalent, particularly for academic and professional development, challenges such as cyberbullying, privacy concerns, and the need for formal training in social media navigation persist. Tailored training programs and guidelines could enhance social media's effective and ethical use in this field, promoting a safe environment for professional expression and engagement.
RESUMO
To evaluate the predictive value of the sFlt-1/PlGF ratio for the prediction of preeclampsia in women with preexisting diabetes mellitus. This is a monocentric retrospective observational study conducted between January 2018 and December 2020. All singleton pregnancies with preexisting diabetes mellitus, who had a dosage of the sFlt-1/PlGF ratio between 30 and 34 + 6 weeks of gestation were included. The principal outcome was preeclampsia. The secondary outcomes were preterm preeclampsia, gestational hypertension, placental abruption, intrauterine fetal death, IUGR, small for gestational age and a composite outcome named "hypertensive disorder of pregnancy" including gestational hypertension, preeclampsia and HELLP syndrome (hemolysis, elevated liver enzymes and low platelet count). Of 63 patients, 22% presented preeclampsia. The area under the curve of sFlt-1/PlGF ratio was 0.90 (95% CI: 0.79-0.96) for the prediction of preeclampsia. The receiver operator characteristic analysis suggested that the optimal sFlt-1/PlGF cutoff to predict preeclampsia was 29, with a sensitivity of 86% (95% CI: 60.1-96.0) and a specificity of 92% (95% CI: 80.8-96.8). A cut-off of 38 provided a sensitivity of 71% (95% CI: 45.4-88.3), a specificity of 92% (95% CI: 80.8-96.8). Further analysis using multivariable methods revealed nephropathy was significantly associated with PE (p = 0.014). The use of the sFlt-1/PlGF ratio during the third trimester of pregnancy seems to be of interest as a prognostic tool to improve multidisciplinary management of patients with preexisting diabetes mellitus.

OBJECTIVE: Sistematic pelvic and para-aortic lymphadenectomy is part of the staging surgery for early-stage epithelial ovarian cancer, with no therapeutic value. The Mapping Sentinel Lymph Nodes In Early-Stage Ovarian Cancer (MELISA) trial prospectively assessed the SLN detection rate and the diagnostic accuracy of the SLN mapping technique in patients with early-stage epithelial ovarian cancer. METHODS: This prospective, single-arm study included patients diagnosed with early-stage epithelial ovarian cancer (FIGO stages I and II), via either primary surgery or re-staging surgery. SLN mapping was performed by injecting 0.2 mL of 37-mBq 99mTc-nanocoloid albumin and 2 mL of 2.5 mg/mL indocyanine green into the infundibulopelvic and utero-ovarian ligaments. After removal of SLNs, a complete systematic pelvic and para-aortic lymphadenectomy was performed. SLN Ultrastaging analysis was applied. The primary outcome was the overall SLN detection rate, either with one or both tracers. Secondary outcomes were the diagnostic accuracy of detecting lymph node metastases and factors that may influence SLN detection. RESULTS: Thirty patients were included. SLNs were identified in 27 patients (90%). Detection rates in primary and re-staging surgery were 89% and 92%, respectively. Para-aortic drainage was the predominant lymphatic spread, observed in 26 of 27 patients. Ultrastaging pathologic reports listed 1 SLN with macrometastasis, 1 with micrometastasis, and 5 with isolated tumor cells; the sensitivity of SLN mapping was 100%, with a false-negative rate of 0%. Univariate analysis showed a nonsignificant higher proportion of patients with uterine fibroids, adenomyosis, and endometriosis (100%, 67%, 67%, respectively) in patients in whom SLNs were not detected. CONCLUSION: SLN mapping has a high detection rate (90%) and is an accurate technique for detecting lymph node involvement in early-stage epithelial ovarian cancer. SLN mapping is a potential alternative to systematic lymphadenectomy to reduce associated morbidity, but further research is needed to evaluate the impact of SLN mapping on oncologic outcomes and its cost-effectiveness.

OBJECTIVE: Our study aimed to evaluate the association between timing of cytoreductive surgery and pattern of presentation of the first recurrence in patients with advanced ovarian cancer. We also aimed to assess the impact of the pattern of recurrence on post-relapse overall survival according to surgical timing. METHODS: This retrospective multicenter study evaluated patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC-IV ovarian cancer. Patients had undergone either primary debulking surgery, early interval debulking surgery after 3-4 cycles of neoadjuvant chemotherapy, or delayed debulking surgery after 6 cycles, with minimal or no residual disease, between January 2008 and December 2015. Survival analyses were conducted using the Log-rank test and the Cox model. Cumulative incidences of the different patterns of recurrence were estimated using a competing risks methodology. RESULTS: A total of 549 patients were included: 175 (31.9%) patients had primary, 224 (40.8%) early interval, and 150 (27.3%) delayed debulking surgery. The cumulative incidence of peritoneal recurrences at 2 years was higher with increasing neoadjuvant cycles (24.4%, 30.9% and 39.2%; p=0.019). For pleural or pulmonary recurrences, it was higher after early interval surgery (9.9%, 13.0% and 4.1%; p=0.022). Median post-relapse overall survival was 33.5 months (95% confidence interval (CI) (24.3 to 44.2)), 26.8 months (95% CI (22.8 to 32.6)), and 24.5 months (95% CI (18.6 to 29.4)) for primary, early interval, and delayed debulking surgery groups, respectively (p=0.025). The pattern of recurrence in a lymph node (hazard ratio (HR) 0.42, 95% CI (0.27 to 0.64)), delayed surgery (HR 1.53, 95% CI (1.11 to 2.13)) and time to first recurrence (HR 0.95, 95% CI (0.93 to 0.96)) were associated with post-relapse overall survival. For primary and early interval surgery, lymph node recurrences were associated with significantly longer post-relapse overall survival. CONCLUSIONS: The pattern of first recurrence was associated with timing of surgery, with peritoneal recurrences being more frequent with the increasing number of cycles of neoadjuvant chemotherapy. Lymph node recurrences were associated with better prognosis, having higher post-relapse overall survival. This improved prognosis of lymphatic recurrences was not observed in patients who underwent delayed surgery.

BACKGROUND: In endometrial cancer (EC), sentinel lymph node (SLN) mapping has emerged as an alternative to systematic lymphadenectomy. Little is known about factors that might influence SLN preoperative detection. The aim of our study was to evaluate the clinical and technical variables that may influence on the success of SLN detection in preoperative lymphatic mapping in patients with intermediate and high-risk EC when performing transvaginal ultrasound-guided myometrial injection of radiotracer (TUMIR). METHODS: Between March 2006 and March 2017, we prospectively enrolled patients with histologically confirmed EC with intermediate or high-risk of lymphatic involvement. All women underwent SLN detection by using TUMIR approach. After radiotracer injection, pelvic and abdominal planar and SPECT/CT images were acquired to obtain a preoperative lymphoscintigraphic mapping. Pattern of drainage was registered and analyzed to identify the factors directly involved in drainage. Sonographer learning curves to perform TUMIR approach were created following Cumulative Sum and Wright methods. Univariate and multivariate analyses were performed using logistic regression. RESULTS: During study period, 123 patients were included. SLN preoperative detection rate was 70.7%. Age under 75 years at diagnosis (P<0.01), radiotracer injection above 4 mL -high-volume- (P<0.01), and tumoral size below 2 cm (P=0.04) were associated with higher SLN preoperative detection rate. Twenty-five procedures were necessary to attain an adequate performance in TUMIR approach. CONCLUSIONS: The higher SLN preoperative detection rate in women with intermediate and high-risk endometrial cancer after TUMIR approach was related with younger age, smaller tumors and high-volume injection of radiotracer. Sonographers are required to perform 25 procedures before acquiring an expertise in radiotracer injection.

BACKGROUND: Recent studies have shown that elective induction of labor versus expectant management after 39 weeks of pregnancy result in lower incidence of perinatal complications, while the proportion of cesarean deliveries remains stable, or even decreases. Still, evidence regarding collateral consequences of the potential increase of induction of labor procedures is still lacking. Also, the results of these studies must be carefully interpreted and thoroughly counter-balanced with women's thoughts and opinions regarding the active management of the last weeks of pregnancy. Therefore, it may be useful to develop a tool that aids in the decision-making process by differentiating women who will spontaneously go into labor from those who will require induction. OBJECTIVE: To develop a predictive model to calculate the probability of spontaneous onset of labor at term. METHODS: We designed a prospective national multicentric observational study including women enrolled at 39 weeks of gestation, carrying singleton pregnancies. After signing an informed consent form, several clinical, ultrasonographic, biophysical and biochemical variables will be collected by trained staff. If delivery has not occurred at 40 weeks of pregnancy, a second visit and evaluation will be performed. Prenatal care will be continued according to current hospital guidelines. Once recruitment is completed, the information gathered will be used to develop a logistic regression-based predictive model of spontaneous onset of labor between 39 and 41 weeks of gestation. A secondary exploration of the data collected at 40 weeks, as well as a survival analysis regarding time-to-delivery outcomes will also be performed. A total sample of 429 participants is needed for the expected number of events. CONCLUSION: This study aims to develop a model which may help in the decision-making process during follow-up of the last weeks of pregnancy. TRIAL REGISTRATION: NCT05109247 (clinicaltrials.gov).

OBJECTIVE: To assess the impact on survival of major postoperative complications and to identify the factors associated with these complications in patients with advanced ovarian cancer after cytoreductive surgery. METHODS: We designed a retrospective multicenter study collecting data from patients with IIIC-IV FIGO Stage ovarian cancer who had undergone either primary debulking surgery (PDS), early interval debulking surgery (IDS) after 3-4 cycles of neoadjuvant chemotherapy, or delayed debulking surgery (DDS) after 6 cycles, with minimal or no residual disease, from January 2008 to December 2015. Univariable and multivariable analyses were conducted to identify factors associated with major surgical complications (≥Grade 3). We assessed disease-free survival (DFS) and overall survival (OS) rates according to the occurrence of major postoperative complications. RESULTS: 549 women were included. The overall rate of major surgical complications was 22.4%. Patients who underwent PDS had a higher rate of major complications (28.6%) than patients who underwent either early IDS (23.2%) or DDS (14.0%). Multivariable analysis revealed that extensive peritonectomy and surgical timing were associated with the occurrence of major complications. Median DFS and OS were 16.9 months (95%CI = [13.7-18.4]) and 48.0 months (95%CI = [37.2-73.1]) for the group of patients with major complications, and 20.1 months (95%CI = [18.6-22.4]) and 56.7 months (95%CI = [51.2-70.4]) for the group without major complications. Multivariable analysis revealed that major surgical complications were significantly associated with DFS, but not with OS. CONCLUSIONS: Patients who experienced major surgical complications had reduced DFS, compared with patients without major morbidity. Extensive peritonectomy and surgical timing were predictive factors of postoperative morbidity.

OBJECTIVE: To gain an overview of the current management of patients with preterm prelabor rupture of membranes (PPROM) in Swiss maternity hospitals. STUDY DESIGN: We conducted a survey among all maternity hospitals in Switzerland from January to December 2018, irrespective of their annual birth rate and level of complexity. The survey consisted of an 11-item questionnaire, which was developed to retrieve information relevant to different areas of PPROM management. RESULTS: Of 64 questionnaires distributed by email, 36 (56.3%) centers responded to the survey. Up to 12 different antibiotic regimens were reported. Among these, 91.7% included a beta-lactam, with amoxicillin as the preferred agent (55.6%). Combined antibiotic schemes were used in 30.6% of hospitals. All centers considered the use of corticosteroids for fetal lung maturity if PPROM occurred before 34 weeks, although 36.1% would consider their use until 37 weeks' gestation in the presence of an increased risk of neonatal respiratory distress syndrome. Maternity hospitals who accept deliveries at any gestational age usually used magnesium sulfate as fetal neuroprotection when delivering babies <32 weeks, with the exception of two hospitals where it was either not used or only indicated if maternal preeclampsia was present. Concerning the time to delivery, 58.3% centers tended to wait until 37 weeks' gestation, while the others considered that it was not necessary to go beyond 34 weeks. CONCLUSION: Our survey shows that the current management of PPROM in Switzerland appears to be mostly in line with international recommendations. However, some heterogeneity exists, thus reflecting a lack of international consensus across guidelines, together with the absence of national Swiss guidelines, and this needs to be addressed to ensure high quality care for all patients and neonates.

PURPOSE: Indocyanine green (ICG) is frequently used for the detection of the sentinel lymph node (SLN) in gynecology, but it carries the loss of the presurgical SLN mapping provided by [99mTc]-based colloids. Hybrid tracers such as ICG-[99mTc]Tc-albumin nanocolloid combine the benefits of both components. The aim of this study was to evaluate the feasibility and applicability of this hybrid tracer injected by transvaginal ultrasound-guided myometrial injection of radiotracer (TUMIR) approach in the detection of SLNs in patients with intermediate- and high-risk EC. METHODS: Fifty-two patients with intermediate- and high-risk EC underwent SLN biopsy after injection of a hybrid tracer using the TUMIR approach, followed by pelvic and paraaortic lymphadenectomy. SLNs were detected preoperatively by lymphoscintigraphic study and intraoperatively by gamma probe and near-infrared (NIR) optical laparoscopic camera. RESULTS: Preoperative lymphatic drainage was obtained in 69% and intraoperative detection in 71.4% of patients. A total of 146 SLNs (4.17 SLNs/patient) were biopsied. Pelvic bilateral detection was observed in 57% of the women and paraaortic drainage in 34% of the patients. The radioactive component allowed the detection of SLN in 97.1% of the patients, while the fluorescent component detected 80%. In more than 17% of the patients with intraoperative detection, SLNs were detected only by the radioactive signal. Lymph node metastasis was identified in 14.3% of patients submitted to SLNB. The sensitivity and negative predictive value for metastatic involvement were 100%. CONCLUSION: TUMIR injection of a hybrid tracer in patients with intermediate- and high-risk EC combines the benefits of the radiotracer and the fluorescence methods with a single tracer. The method increases the paraaortic detection rate and allows a potential increase in SLN detection. Notwithstanding, based on our findings, the radioactive component of the hybrid tracer cannot be obviated.
RESUMO
OBJECTIVE: We sought to evaluate the impact on survival of tumor burden and surgical complexity in relation to the number of cycles of neoadjuvant chemotherapy (NACT) in patients with advanced ovarian cancer (OC) with minimal (CC-1) or no residual disease (CC-0). METHODS: This retrospective study included patients with International Federation of Gynaecology and Obstetrics IIIC-IV stage OC who underwent debulking surgery at 4 high-volume institutions between January 2008 and December 2015. We assessed the overall survival (OS) of primary debulking surgery (PDS group), early interval debulking surgery after 3-4 cycles of NACT (early IDS group) and delayed debulking surgery after 6 cycles (DDS group) with CC-0 or CC-1 according to peritoneal cancer index (PCI) and Aletti score. RESULTS: Five hundred forty-nine women were included: 175 (31.9%) had PDS, 224 (40.8%) early IDS and 150 (27.3%) DDS. Regardless of Aletti score, median OS after PDS was significantly higher than after early IDS or DDS, but the survival difference was higher in women with an Aletti score <8. Among patients with PCI ≤10, median OS after PDS was significantly higher than after early IDS or DDS. In women with PCI >10, there were no differences between PDS and early IDS, but DDS was associated with decreased OS. CONCLUSION: The benefit of complete PDS compared with NACT was maximal in patients with a low complexity score. In patients with low tumor burden, there was a survival benefit of PDS over early IDS or DDS. In women with high tumor load, DDS impaired the oncological outcome.

OBJECTIVE: To evaluate the concordance between preoperative European Society for Medical Oncology (ESMO)-European Society of Gynaecological Oncology (ESGO)-European SocieTy for Radiotherapy and Oncology (ESTRO) risk classification in early-stage endometrial cancer (EC) assessed by biopsy and magnetic resonance imaging (MRI) with this classification based on histology of surgical specimen. METHODS: This bicentric retrospective study included women diagnosed with early-stage EC (≤stage II) who had a complete preoperative assessment and underwent a surgical management from January 2011 to December 2018. Patients were preoperatively classified into 3 degrees of risk of lymph node (LN) involvement based on biopsy and MRI. Based on final histological report, patients were re-classified using the preoperative classification. Concordance between the preoperative assessment and definitive histology was calculated with weighted Cohen's kappa coefficient. RESULTS: A total of 333 women were included and kappa coefficient of preoperative risk classification was 0.49. The risk was underestimated and overestimated in 37% and 10% of cases, respectively. Twenty-nine percent of patients had an incomplete LN staging according to the degree of risk of re-classification. The observed discordance in the risk classification was attributed to MRI in 75% of cases, to biopsy in 18% and in 7% to both (p<0.001). Kappa coefficient for concordance was 0.25 for MRI and 0.73 for biopsy. CONCLUSION: Concordance between preoperative ESMO-ESGO-ESTRO risk classification and final histology is weak. Given that the risk was underestimated in the majority of patients wrongly classified, sentinel LN procedure instead of no LN dissection could be an option offered to preoperative low-risk patients to decrease the indication of second surgery for re-staging and/or to avoid toxicity of adjuvant radiotherapy.

OBJECTIVE: We aimed to evaluate the accuracy of sentinel lymph node (SLN) mapping with transvaginal ultrasound-guided myometrial injection of radiotracer (TUMIR) to detect lymph node (LN) metastases, in patients with intermediate and high-risk endometrial cancer (EC), focusing on its performance to detect paraaortic involvement. METHODS: Prospective study including women with preoperative intermediate or high-risk EC, according to ESMO-ESGO-ESTRO consensus, who underwent SLN mapping using the TUMIR approach. SLNs were preoperatively localized by planar and single photon emission computed tomography/computed tomography images, and intraoperatively by gamma-probe. Immediately after SLN excision, all women underwent systematic pelvic and paraaortic lymphadenectomy by laparoscopy. RESULTS: The study included 102 patients. The intraoperative SLN detection rate was 79.4% (81/102). Pelvic and paraaortic drainage was observed in 92.6% (75/81) and 45.7% (37/81) women, respectively, being exclusively paraaortic in 7.4% (6/81). After systematic lymphadenectomy, LN metastases were identified in 19.6% (20/102) patients, with 45.0% (9/20) showing paraaortic involvement, which was exclusive in 15.0% (3/20). The overall sensitivity and negative predictive value (NPV) of SLNs by the TUMIR approach to detect lymphatic involvement were 87.5% and 97.0%, respectively; and 83.3% and 96.9%, for paraaortic metastases. After applying the MSKCC SLN mapping algorithm, the sensitivity and NPV were 93.8% and 98.5%, respectively. CONCLUSION: The TUMIR method provides valuable information of endometrial drainage in patients at higher risk of paraaortic LN involvement. The TUMIR approach showed a detection rate of paraaortic SLNs greater than 45% and a high sensitivity and NPV for paraaortic metastases in women with intermediate and high-risk EC.

INTRODUCTION: The objective was to evaluate whether hybrid imaging combining single photon emission tomography with computed tomography (SPECT/CT) provides additional clinical value for dectection of sentinel lymph nodes (SLNs) compared with intraoperative combined mapping in uterine and cervical malignancies. METHODS: This was a retrospective study of prospectively collected data from patients with stages IA-IB2 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2018) or stage I endometrial cancer, who underwent preoperative SPECT/CT for SLN detection. All included patients had dual injection of technetium-99m (99mTc) with patent blue or indocyanine green. RESULTS: A total of 171 patients were included with 468 SLNs detected during surgery: 146/171 patients (85.4%) had both radiotracer and blue injection whereas 25/171 patients (14.6%) had radiotracer and indocyanine green injected. The overall detection rate was 95.3%. The detection rate of SLN mapping was 74.9% for SPECT/CT, 90.6% for 99mTc, 91.8% for blue dye, and 100% for indocyanine green. Bilateral drainage was found in 140 patients (81.9%), detected by 99mTc in 105 patients (61.4%), by blue in 99 patients (67.3%), by indocyanine green in 23 patients (92%), and by SPECT/CT in 62 patients (36.4%). Atypical SLN locations were identified by SPECT/CT in 64 patients (37.4%), by 99mTc in 28 patients (16.4%), by blue in 17 patients (9.9%), and by indocyanine green in 8 patients (4.7%). Sensitivity and negative predictive value of SLN biopsy to detect lymph node metastasis using dual injection of different intraoperative combined techniques were 88.9% and 97.5%, respectively. CONCLUSION: SPECT/CT enhanced topographic delineation of SLN and more accurately identified drainage to atypical locations. Fluorescent SLN mapping using indocyanine green offered the highest SLN detection rate. When indocyanine green was used, SPECT/CT did not increase SLN detection, and did not add further information to improve lymph node localization and removal.

BACKGROUND: Gastric perforation after cytoreductive surgery (CRS) is an infrequent complication. There is lack of evidence regarding the risk factors for this postoperative complication. The aim of this study was to assess the prevalence of postoperative gastric perforation in patients undergoing CRS for peritoneal carcinomatosis (PC) and to evaluate risk factors predisposing to this complication. METHODS: We designed a unicentric retrospective study to identify all patients who underwent an open upfront or interval CRS after a primary diagnosis of PC of different origins between March 2007 and December 2018 at a French Comprehensive Cancer Center. The main outcome was the occurrence of postoperative gastric perforation. RESULTS: Five hundred thirty-three patients underwent a CRS for PC during the study period and 13 (2.4%) presented a postoperative gastric perforation with a mortality rate of 23% (3/13). Neoadjuvant chemotherapy was administered in 283 (53.1%) patients and 99 (18.6%) received hyperthermic intraperitoneal chemotherapy (HIPEC). In the univariate analysis, body mass index (BMI), peritoneal cancer index, splenectomy, distal pancreatectomy, and histology were significantly associated with postoperative gastric perforation. After multivariate analysis, BMI (OR [95%CI] = 1.13 [1.05-1.22], p = 0.002) and splenectomy (OR [95%CI] = 26.65 [1.39-509.67], p = 0.029) remained significantly related to the primary outcome. CONCLUSIONS: Gastric perforation after CRS is a rare event with a high rate of mortality. While splenectomy and increased BMI are risk factors associated with this complication, HIPEC does not seem to be related. Gastric perforation is probably an ischemic complication due to a multifactorial process. Preventive measures such as preservation of the gastroepiploic arcade and prophylactic suture of the greater gastric curvature require further assessment.

PURPOSE: The aim of our study was to assess concordance of staging laparoscopy and cytoreductive surgery (CRS) peritoneal cancer index (PCI) when applying a two-step surgical protocol. We also aimed to evaluate the accuracy of diagnostic laparoscopy to triage patients for complete cytoreduction, and to define optimal time between staging laparoscopy and CRS. METHODS: We designed a retrospective review of prospectively collected data from patients with advanced ovarian cancer who underwent a diagnostic laparoscopy followed by a CRS a few weeks later (two-step surgical protocol), from January 2010 to April 2019. Only patients selected for complete cytoreduction, and with available PCI score from both surgeries were included. PCI concordance was assessed using intraclass correlation coefficient (ICC). RESULTS: During the study period 543 patients underwent a laparoscopic staging for ovarian carcinomatosis. Among them, 43 patients fulfilled inclusion criteria. ICC between laparoscopic and laparotomic PCI was 0.54. After applying the linear regression equation: laparoscopic PCI + 0.2 x [days between surgeries] + 2, ICC increased to 0.79. Completeness cytoreduction score and laparoscopic PCI were significantly associated (OR 1.27, 95% CI 1.03-1.57, p = 0.03). AUC of laparoscopic PCI to predict complete cytoreduction was 0.90. CONCLUSION: Concordance between laparoscopic PCI assessment and PCI score at the end of CRS is fair within a two-step surgical management. Laparoscopic assessment underestimates final PCI score by two points, and this difference increases with the delay between both surgeries. Diagnostic laparoscopy can adequately select patients for CRS, and optimal time to perform it is no more than 10 days after laparoscopy.

INTRODUCTION: Sentinel lymph node (SLN) detection has been shown to be accurate in detecting lymph node involvement in early-stage cervical cancer. The objective of this study was to evaluate the accuracy of frozen section examination in the assessment of SLN status, with the aim of adequately driving the intra-operative decision. METHODS: We designed a retrospective study including patients from two comprehensive cancer centers between January 2001 and December 2018 with early-stage cervical cancer (IA1-IB2 according to International Federation of Gynecology and Obstetrics (FIGO) 2018) undergoing SLN dissection. The SLN procedure was performed using a cervical injection with technetium-99m combined with blue dye or indocyanine green in most cases. RESULTS: A total of 176 patients fulfilled inclusion criteria. Bilateral mapping was detected in 153 (86.7%) of them. Nineteen of these patients (12.4%) had SLN involvement: 13 with macrometastases, three with micrometastases and three with isolated tumor cells (ITC). Macrometastatic disease was missed on frozen section in 3/13 FIGO 2018 stage IIIC patients. The three patients with ITC were also missed by frozen section examination.Considering only macrometastases as lymph node involvement, frozen section sensitivity was 76.9% (95% CI 49.7 to 91.8) and negative predictive value (NPV) was 97.9% (95% CI 94.0 to 99.3) in patients with bilateral detection. Including micrometastases, sensitivity was 81.2% (95% CI 57.0 to 93.4) and NPV remained at 97.9% (95% CI 93.9 to 99.3). CONCLUSIONS: With a prevalence of final-stage IIIC in patients with pre-operative early-stage cervical cancer of the order of 10% in this series, the NPV of frozen section examination of SLN is very high, with an inferior limit of the CI superior to 94%. Diagnostic accuracy remains acceptable even if micrometastases are considered. The impact of missed ITC has not been established. Frozen section examination can be incorporated in the intra-operative decision algorithm.

BACKGROUND: Pelvic exenteration and its reconstructive techniques have been associated with high postoperative morbidity and a negative impact on patient quality of life. The aim of our study was to compare postoperative complications and quality of life in patients undergoing continent compared with non-continent urinary diversion after pelvic exenteration for gynecologic malignancies. METHODS: We designed a multicenter study of patients from 10 centers who underwent an anterior or total pelvic exenteration with urinary reconstruction for histologically confirmed persistent or recurrent gynecologic malignancy after previous treatment with radiotherapy. From January 2005 to September 2008, we included patients retrospectively, and from September 2008 to May 2009, patients were included prospectively which allowed collection of quality of life data. Demographic, surgical, and follow-up data were analyzed. Postoperative complications were classified according to the Clavien-Dindo classification. Quality of life was assessed using the European Organization for Research and Treatment of Cancer (EORTC)-QLQ-C30 (V.3.0) and EORTC-QLQ-OV28 quality of life questionnaires. We compared patients who underwent a continent urinary diversion with those who underwent a non-continent reconstruction. RESULTS: We included 148 patients, 92 retrospectively and 56 prospectively. Among them, 77.4% had recurrent disease and 22.6% persistent disease after the primary treatment. In 70 patients, a urinary continent diversion was performed, and 78 patients underwent a non-continent diversion. Median age of the continent and incontinent groups was 53.5 (range 33-78) years and 57 (26-79) years, respectively. There were no significant differences between the continent and non-continent groups in median length of hospitalization (28.5 vs 26 days, P=0.19), postoperative grade III-IV complications (42.9% vs 42.3%, P=0.95), complications needing surgical (27.9% vs 34.6%, P=0.39) or radiological (14.7% vs 12.8%, P=0.74) intervention, and complication type (digestive (23.2% vs 16.7%, P=0.32) and urinary (15.9% vs 16.7%, P=0.91)). There were no significant differences between the groups in global health, global quality of life, and body image perception scores 1 year after surgery. CONCLUSION: Continent and incontinent urinary reconstructions are equivalent in terms of postoperative complications and quality of life scores.

Both caesarean surgery and induction of labour are common practices performed in all labour wards in an attempt to reduce adverse obstetrical and neonatal outcomes. Recent evidence, notably from the ARRIVE Trial, demonstrated that elective induction at 39 weeks reduced the rate of caesarean deliveries and pregnancy-related hypertensive disorders. However, some concerns have to be addressed as the benefits of universal policies have to be weighed against the actual circumstances of their implementation, the economic impact, the number of procedures needed in order to effectively reduce complications and, above all, women's perception towards this approach at the end of pregnancy. Further research is needed to explore individual tailored strategies in order to offer a personalized prognosis to each woman, rather than a blanket application of general recommendations.
