Objective: Interval debulking surgery is recommended after 3-4 cycles (standard IDS) of neoadjuvant chemotherapy (NACT) for epithelial ovarian cancer (EOC) not able to received upfront complete debulking surgery. However, real world practices frequently report performing IDS after ≥5 NAC cycles (delayed IDS). The aim of this work was to evaluate the impact on survival of the number of NACT cycles before IDS., Methods: We identified from a French national database, women with newly diagnosed EOC who underwent IDS from January 2011 to December 2016. Progression free survival (PFS) and overall survival (OS) were compared using Cox model with adjustments for confounding factors provided by two propensity score methods: inverse probability of treatment weighting (IPTW) and matched-pair analysis., Results: 928 patients treated by IDS for which our propensity score could be applied were identified. After a median follow-up of 49.0 months (95% CI [46.0;52.9]); from the IPTW analysis, median PFS was 17.6 months and 11.5 months (HR = 1.42; CI 95% [1.22-1.67]; p < 0.0001); median OS was 51.2 months and 44.3 months (HR = 1.29; CI 95% [1.06-1.56]; p = 0.0095) for the standard and delayed IDS groups. From the matched-pair analysis (comparing 352 patients for each group), standard IDS was associated with better PFS (HR = 0,77; CI 95% [0.65-0.90]; p = 0.018) but not significantly associated with better OS (HR = 0,84; CI 95% [0.68-1,03]; p = 0.0947)., Conclusions: Carrying IDS after ≥5 NACT cycles seems to have a negative effect on patients survival. The goal of IDS surgery is complete resection and should not be performed after >3-4 NACT cycles., Competing Interests: Declaration of Competing Interest All the authors declare that they have no conflicts of interest to disclose related to this work., (Copyright © 2022 The Authors.

Background: Prognostic significance of endometrioid epithelial ovarian cancer (EOC) is controversial. We compared clinical, pathological, and biological features of patients with endometrioid and serous EOC, and assessed the independent effect of histology on outcomes., Methods: We conducted a multicenter retrospective analysis of patients with EOC selected from the French Epidemiological Strategy and Medical Economics OC database between 2011 and 2016. Our main objective was to compare overall survival (OS) in endometrioid and serous tumors of all grades. Our second objectives were progression-free survival (PFS) and prognostic features., Results: Out of 10,263 patients included, 3180 cases with a confirmed diagnosis of serous (N = 2854) or endometrioid (N = 326) EOC were selected. Patients with endometrioid histology were younger, more often diagnosed at an early stage, with lower-grade tumors, more frequently dMMR/MSI-high, and presented more personal/familial histories of Lynch syndrome-associated cancers. BRCA1/2 mutations were more frequently identified in the serous population. Endometrioid patients were less likely to receive chemotherapy, with less bevacizumab. After median follow-up of 51.7 months (95CI[50.1-53.6]), five-year OS rate was 81% (95CI[74-85]) in the endometrioid subgroup vs. 55% (95CI[53-57] in the serous subset (p < 0.001, log-rank test). In multivariate analyses including [age, ECOG-PS, FIGO, grade, and histology], the endometrioid subtype was independently associated with better OS (HR = 0.38, 95CI[0.20-0.70], p= 0.002) and PFS (HR = 0.53, 95CI[0.37-0.75], p < 0.001)., Conclusions: Clinicopathological features at diagnosis are not the same for endometrioid and serous EOC. Endometrioid histology is an independent prognosis factor in EOC. These observations suggest the endometrioid population requires dedicated clinical trials and management., Competing Interests: Declaration of Competing Interest All the authors declare that they have no conflicts of interest to disclose related to this work., (Copyright © 2021 Elsevier Inc.

Objective: FIGO stage I endometrial cancers are divided into two substages, regardless of the presence or absence of lymphovascular space invasion (LVSI). The aim of this study was to investigate whether stratification based on the LVSI status would better predict mortality., Methods: Using a multicentric database, we identified patients who underwent endometrial cancer operations between 2000 and 2010. The staging performance was quantified with respect to discrimination., Results: The study cohort included 508 patients (198 with LVSI-positive tumors and 310 with LVSI-negative tumors). The survival difference between the stage I patients with LVSI-positive and LVSI-negative tumors was highly significant (81% and 97%, respectively P=.009), whereas the difference between the stage I patients with tumors invading greater or less than half of the myometrium was not (87% and 96%, respectively P=0.09). The 5-year OS rates for the patients with LVSI-negative tumors invading less than half of the myometrium, with LVSI-negative tumors invading more than half of the myometrium and with LVSI-positive invading more than or less than half of the myometrium were 98%, 95%, and 81%, respectively (P=.03). Separating the LVSI-negative and LVSI-positive tumors would improve discrimination (concordance index, 77% vs. 75%, respectively, using the actual staging system)., Conclusion: A LVSI-positive status has a significantly worse prognosis. In this study, the distinction by LVSI status appears to be more relevant than the distinction between stages IA and IB for predicting survival in stage I endometrial cancer. This difference in prognosis would favor restaging these two entities., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Objective: The aim of this study was to evaluate the impact of lymphovascular space invasion (LVSI) on nomogram-based predictions of lymph node (LN) metastasis in endometrial cancer., Methods: The data from 485 patients with presumed stage I or II endometrial cancer who underwent hysterectomy and lymphadenectomy were analyzed. Calibration curves were designed and compared for three different subgroups: LVSI-positive tumors (n=113), LVSI-negative tumors (n=213) and LVSI-undetermined tumors (n=159)., Results: In the entire population, the nomogram showed good discrimination with an area under the receiver operating characteristic curve (AUC) of 0.80 and was well calibrated. In the subgroup analyses, in LVSI-positive, LVSI-negative and LVSI-undetermined patients, the nomogram was not well calibrated (p of the U index of 0.028, 0.087 and 0.011, respectively) with underestimation in LVSI-positive patients and overestimation in LVSI-negative and LVSI-undetermined patients of LN metastasis. In the univariate analysis and after adjusting for the LN metastasis probability provided by the nomogram, LVSI-positive tumors were associated with an increased risk for LN metastasis compared with LVSI-negative tumors (RR=7.29 [3.87-13.7] and 5.04 [2.30-11.08], respectively). In contrast, the univariate analysis and after adjusting for the LN metastasis probability provided by the nomogram showed that LVSI-undetermined tumors were not associated with an increased risk for LN metastasis compared with LVSI-negative tumors (RR=0.73 [0.32-1.69] and 1.26 [0.47-3.37], respectively)., Conclusions: Our results suggested that LVSI should be considered to be an independent risk factor for LN metastasis. In this multicenter study, the risk for LN metastasis is similar when the LVSI is negative or is not detailed in the pathological report., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Background: Patent blue is a commonly used agent in the detection of sentinel nodes (SN) in solid cancer. Similar to any drug, it is possible to have an allergic reaction during surgery. Anaphylactic reactions to patent blue have been rarely reported especially in cervical cancer., Case: We reported here a rare case of anaphylactic shock due to patent blue in response to injection of patent blue for SN mapping in a woman with cervical cancer. We presented our management of the shock, our diagnostic process of the allergen and the treatment of the cervix cancer after the anaphylactic reaction., Conclusion: Surgeons and anesthetists must be aware of the potential allergic of patent blue during the SN procedure.

Objective: The required radicality of hysterectomy for women with early-stage cervical cancer is controversial owing to the risk of severe complications. The aim of this study was to determine the contribution of the sentinel node (SN) procedure to tailoring the radicality of hysterectomy in women with cervical cancer., Methods: Between April 2001 and December 2005, 54 patients with early-stage or locally advanced cervical cancer underwent laparoscopic sentinel node (SN) biopsy based on combined patent blue and radiocolloid detection. Thirty-nine patients with early-stage cervical cancer underwent a laparoscopic SN procedure with complete pelvic lymphadenectomy and radical hysterectomy. Moreover, 15 women with locally advanced cervical cancer underwent an SN procedure with pelvic and para-aortic lymphadenectomy before concurrent neoadjuvant chemoradiotherapy., Results: The SN detection rate was 83.3%. The detection rate was higher in women with early-stage disease (90%) than in women with more advanced disease (66.6%) (p=0.03). At final histology, 14 metastatic SN were found in 11 (21.3%) of the 54 patients. They comprised macrometastases in 6 SN, micrometastases in 5 SN, and isolated tumour cells in 3 SN. Parametrial involvement with negative sentinel nodes was found in 15.1% of cases. The overall sensitivity, specificity, positive and negative predictive values and accuracy of intraoperative imprint cytology were 20%, 100%, 100%, 79.5% and 80.5%, respectively. Among the 39 women with early cervical cancer, five (12.8%) had parametrial involvement. In univariate analysis, parametrial involvement was significantly associated with large tumour size, advanced-stage disease, positive pelvic lymph nodes and lymphovascular space involvement. Parametrial involvement tended to be associated with positive sentinel nodes., Conclusion: These results underline the contribution of the SN procedure to evaluating lymph node status. However, intraoperative imprint cytology appeared poorly accurate, and further histological or biological tools are needed to evaluate SN status and, hence, to tailor the radicality of hysterectomy.

Background: The risk of wound metastasis after laparoscopic management of early-stage cervical cancer is well known, but there are few data on peritoneal carcinomatosis of cervical adenocarcinoma., Case: We report the first case of peritoneal carcinomatosis occurring in a woman with FIGO stage Ib1 cervical adenocarcinoma who underwent laparoscopic type III radical hysterectomy and bilateral pelvic lymphadenectomy (sentinel node procedure) followed by vaginal brachytherapy. A peritoneal recurrence was diagnosed 16 months after surgery and was treated with chemotherapy and laparotomy., Conclusion: Laparoscopy for cervical adenocarcinoma may carry a risk of peritoneal dissemination.

Background: Positron emission tomography and computed tomography (PET/CT) have a potential role in detecting and locating recurrent ovarian cancer. Precise tumor location during surgical treatment is often difficult, owing to limited tumor size and post-surgical anatomic modifications. The surgical gamma probe, which has become increasing popular in recent years with the development of sentinel node mapping, may improve tumor detection and facilitate resection of occult metastases., Case Report: We describe the first case of laparoscopic resection of occult metastasis using the combination of FDG-PET/CT image fusion with intraoperative FDG-sensitive probing in a patient with recurrent ovarian cancer., Conclusion: FDG-sensitive probe combined with preoperative PET/CT image fusion can help to detect occult metastasis and guide laparoscopic excision.

Objective: The purpose of this study was to evaluate intraoperative imprint cytology (IC) for the detection of sentinel node (SN) involvement in patients with cervical cancer., Methods: Thirty-six consecutive patients with cervical cancer underwent a laparoscopic SN procedure with intraoperative IC, followed by complete laparoscopic pelvic lymphadenectomy, with or without laparoscopic para-aortic lymphadenectomy. The SN was bisected and both cut surfaces were applied to the surface of glass slides. Permanent sections were stained with H&E and immunohistochemical methods. The IC results were compared with the final histological results., Results: At least one SN (mean: 2 SN per patient, range: 1-5) was detected in 34 of the 36 patients. Eight patients (22.2%) had a total of 12 metastatic SNs (four macrometastatic, five micrometastatic, and three with isolated tumor cells). No false-negative results of SN biopsy were obtained. Only one metastasis was identified by IC. No false-positive findings were obtained with IC. The overall sensitivity, specificity, accuracy, and positive and negative predictive values of IC were 8.3%, 100%, 85.7%, 100%, and 85.5%, respectively., Conclusion: These results suggest that intraoperative imprint cytology of sentinel nodes is unreliable in patients with cervical cancer.

Background: Laparoscopic pelvic lymph node dissection in combination with a vaginal radical Schauta-Amreich operation has become an alternative for women with early-stage cervical cancer., Case: We described the first case of metastasis on Schuchardt's incision after Schauta-Amreich operation for neuroendocrine cervical cancer., Conclusion: Metastasis on Schuchardt's incision after Schauta-Amreich operation can rarely be the metastatic localization of the cervical carcinoma.
