Global practice patterns of sentinel lymph node biopsy in endometrial cancer: a survey from the European Network of Young Gynecologic Oncologists (ENYGO)

This survey aimed to evaluate trends in sentinel lymph node (SLN) biopsy for endometrial cancer among members of the European Society of Gynecologic Oncology (ESGO) and the International Gynecologic Cancer Society (IGCS). We conducted an online cross-sectional survey among gynecologic oncologists over 40 years of age consisting of 30 questions. It was distributed to ESGO and IGCS members via Survey Monkey and Qualtrics between September and December 2022. Surveys were excluded in the analysis if >50% of questions were incomplete. Statistical analysis, performed with SPSS version 27.0. A total of 302 (70.2%) of 430 participants completed the survey, with 159 (52.6%) affiliated with ESGO and 143 (47.4%) with IGCS. The majority were male 206 (68.2%), and 170 (56.3%) were based in Europe. Most respondents (n = 261, 86.4%) were certified gynecologic oncologists. Indocyanine green was the most common tracer used (n = 234, 77.5%), with higher rates of blue dye injections among IGCS respondents (p = .002). The predominant injection volume was 4 cm This study showed significant variations in SLN biopsy practices for endometrial cancer, underscoring the need for global standardization through harmonized guidelines, consistent training, and international collaboration to improve staging accuracy and patient outcomes.

Fertility-sparing treatment in patients with placental trophoblastic site tumor: a systematic review

Placental site trophoblastic tumor (PSTT) is a rare pathologic entity of gestational trophoblastic neoplasia. The main objective of the present manuscript is to summarize current evidence regarding the possibility of fertility-sparing management. A systematic review of the literature was conducted to evaluate the efficacy, oncological safety, and fertility-preservation outcomes in patients with PSTT undergoing fertility-sparing management. PubMed, Scopus, and Cochrane Library were searched to identify proper articles. Eligibility criteria included all prospective or retrospective cohorts reporting conservative management of PSTT. Primary outcomes were the rate of recurrence and fertility outcome. Secondary outcomes concerned the type of conservative management. Overall, 16 articles were retrieved including a total of 63 patients. The mean age was 28.3 years (range; 21-37) and the mean serum beta-human chorionic gonadotropin was 17,251.9 IU/L (range; <0.1 to 430,290 IU/L). Regarding the antecedent pregnancy, 41.3% (26 cases) were full-term pregnancies, and 30.2% (19 cases) were abortions. Most cases were International Federation of Gynecology and Obstetrics stage I (73%). The overall recurrence rate of disease was 13.8% (8 of 63 patients) with these patients all treated with hysterectomy after recurrence. There were overall 23 full-term pregnancies reported, indicating a 36.5% fertility rate per patient, while 2 pregnancies are still ongoing at the time of publication. Fertility-sparing management of patients with PSTT is feasible and oncologically safe, with 36.5% fertility outcomes.

Concurrent RB1 Loss and BRCA Deficiency Predicts Enhanced Immunologic Response and Long-term Survival in Tubo-ovarian High-grade Serous Carcinoma

Abstract Purpose: The purpose of this study was to evaluate RB1 expression and survival across ovarian carcinoma histotypes and how co-occurrence of BRCA1 or BRCA2 (BRCA) alterations and RB1 loss influences survival in tubo-ovarian high-grade serous carcinoma (HGSC). Experimental Design: RB1 protein expression was classified by immunohistochemistry in ovarian carcinomas of 7,436 patients from the Ovarian Tumor Tissue Analysis consortium. We examined RB1 expression and germline BRCA status in a subset of 1,134 HGSC, and related genotype to overall survival (OS), tumor-infiltrating CD8+ lymphocytes, and transcriptomic subtypes. Using CRISPR-Cas9, we deleted RB1 in HGSC cells with and without BRCA1 alterations to model co-loss with treatment response. We performed whole-genome and transcriptome data analyses on 126 patients with primary HGSC to characterize tumors with concurrent BRCA deficiency and RB1 loss. Results: RB1 loss was associated with longer OS in HGSC but with poorer prognosis in endometrioid ovarian carcinoma. Patients with HGSC harboring both RB1 loss and pathogenic germline BRCA variants had superior OS compared with patients with either alteration alone, and their median OS was three times longer than those without pathogenic BRCA variants and retained RB1 expression (9.3 vs. 3.1 years). Enhanced sensitivity to cisplatin and paclitaxel was seen in BRCA1-altered cells with RB1 knockout. Combined RB1 loss and BRCA deficiency correlated with transcriptional markers of enhanced IFN response, cell-cycle deregulation, and reduced epithelial–mesenchymal transition. CD8+ lymphocytes were most prevalent in BRCA-deficient HGSC with co-loss of RB1. Conclusions: Co-occurrence of RB1 loss and BRCA deficiency was associated with exceptionally long survival in patients with HGSC, potentially due to better treatment response and immune stimulation.

Health care organization for gynecologic oncology patients fleeing Ukraine: Insights from the European Network of Young Gyne Oncologists survey during the first six months of the military conflict

The Russian invasion of Ukraine in February 2022 caused a mass displacement of over 6 million people, including many women requiring urgent medical care, such as those with gynecologic malignancies. The disruption of cancer treatment in conflict zones poses critical challenges because timely oncologic care is vital for patient survival. This study, conducted by the European Network of Young Gynecologic Oncologists, aimed to assess the health care responses provided to Ukrainian gynecologic oncology patients across European countries during the first 6 months of the conflict. A cross-sectional survey was distributed to European Network of Young Gynecologic Oncologists members between July and August 2022, gathering insights from health care providers about their experiences in managing Ukrainian gynecologic oncology patients. The survey explored the medical needs of displaced patients, challenges encountered, and the resources available. Descriptive statistics were used for data analysis. During the study period, approximately 400 gynecologic oncology patients fleeing Ukraine received care in 38 European health care centers represented by the respondents (N = 50). Surgical interventions (54%), chemotherapy (40%), and specialist consultations (32%) were identified as the most common medical needs. The key barriers to care included language difficulties (44%), lack of previous medical documentation (40%), and inconsistencies in treatment protocols between centers. Psychological support was notably insufficient, with 36% of respondents reporting a lack of adequate resources for addressing mental health needs. The study identifies critical barriers to the continuity of gynecologic oncology care for displaced patients during humanitarian crises. Addressing language barriers, ensuring access to patient medical histories, and providing psychological support are essential to improve care for refugees. The findings underscore the importance for international collaboration and the development of robust frameworks for delivering oncologic care during crises.

Declaration on cervical cancer elimination: literature review and perspectives from early-career clinicians.

Despite effective prevention methods, cervical cancer remains one of the most incident malignancies globally. This literature review and perspectives from early-career clinicians aim to propose actionable recommendations to reduce the global burden of cervical cancer. The authors, representing the early-career clinicians and researchers, patient representatives, epidemiologists, and gynecologic oncology experts, identified 5 key pillars for cervical cancer elimination based on literature reviews and interdisciplinary discussion: (1) raising awareness of human papillomavirus (HPV) and cervical cancer; (2) ensuring evidence-based HPV communication; (3) fostering collaboration with other specialties and organizations; (4) increasing HPV vaccination rates; and (5) improving cervical cancer screening. Achieving the World Health Organization's cervical cancer elimination target by 2030 requires a comprehensive, multi-faceted approach. Our recommendations emphasize the need for targeted awareness campaigns, evidence-based communication, collaboration with various stakeholders, promotion of best practices, and keeping evidence of innovative interventions up-to-date, with intensified efforts in low- and middle-income countries where the burden is the greatest.

Global survey on training and practice in sentinel lymph node mapping for endometrial and cervical cancer among early-career gynecologic oncologists

This survey was designed to evaluate exposure to sentinel mapping for cervical and endometrial cancers in addition to the quality and availability of surgical training in sentinel procedures around the world. Furthermore, we aimed to identify obstacles in surgical training in the sentinel procedure to support the adoption of this technique in clinical practice. A 52-item survey was developed and computed using Qualtrics XM and SurveyMonkey software. The target population were members of the European Society of Gynaecological Oncology and the International Gynecological Cancer Society aged ≤40 years. The study invitation was disseminated within both organizations' database. The survey hyperlink was active between September and December 2022. Respondents using the same Internet Protocol address were excluded to avoid duplication of responses. Responses to <50% questions were excluded. Overall, 238 respondents joined the survey, and 182 (76.5%) provided answers that met the inclusion criteria. Sentinel mapping was implemented for a longer period and used more frequently in endometrial than in cervical carcinoma; 55% of the responders were initially trained in systematic lymph node dissection, and 22% were not yet trained in any lymph node staging. The main challenges in applying sentinel procedure for early-career gynecologic oncologists were no access to hands-on training (n = 22, 12.1%) and no clinical routine in performing systematic pelvic (n = 15, 8.2%) and para-aortic (n = 35, 19.2%) lymph node dissection in case of failed mapping. Although sentinel lymph node biopsy is integrated in cervical and endometrial cancer guidelines, a significant number of institutions do not implement this procedure in clinical routine, and 22% of early-career gynecologic oncologists are not trained in any type of surgical lymph node staging. Support for sentinel mapping in national guidelines and guided training opportunities are needed to apply this method globally.
