Treatment and survival of patients with malignant ovarian sex cord-stromal cell tumours: An analysis of the Arbeitsgemeinschaft für Gynäkologische Onkologie (AGO) study group CORSETT database.

BACKGROUND: Malignant sex cord-stromal cell tumours (SCST) account for only 7% of ovarian malignancies. The Arbeitsgemeinschaft fuer Gynaekologische Onkologie (AGO) study group has established a clinicopathological database to provide an overview of the current treatment strategies and survival of SCST patients and to identify research needs. METHODS: Twenty centres provided mixed retro- and prospective data of patients with tumour specimens and second-opinion pathology review treated between 2000 and 2014. Descriptive analyses of treatment strategies, Kaplan-Meier curves and cox regression analyses were conducted. RESULTS: Two hundred and sixty-two SCST patients were included. One hundred and ninety-one Granulosa-cell tumour (GCT) and 17 Sertoli-Leydig cell tumour (SLCT) patients were stage I disease (>80%). Forty four GCT (18.7%) and two (8.3%) SLCT patients received adjuvant systemic treatment. After a median observation time of 78.2 months, 46% of all SCST patients experienced disease recurrence, treated predominantly with secondary debulking surgery (> 90%). Advanced FIGO stage, lymph node involvement and intra-operative capsule rupture were associated with disease recurrence on univariate analysis (all p < 0.05). Median OS time was not reached. DISCUSSION: In this analysis of SCST patients, adjuvant chemotherapy was unable to prevent disease recurrence. Despite high recurrence rates, overall survival rates were excellent.

Prognostic factors and survival of patients with uterine sarcoma: a German unicenter analysis.

PURPOSE: Uterine sarcoma (US) as a histologically heterogeneous group of tumors is rare and associated with poor prognosis. Prognostic factors based on systematic data collection need to be identified to optimize patients' treatment. METHODS: This unicenter, retrospective cohort study includes 57 patients treated at the University Hospital Freiburg, Germany between 1999 and 2017. Progression-free survival (PFS) and overall survival (OS) were calculated and visualized in Kaplan-Meier curves. Prognostic factors were identified using log-rank test and Cox regression. RESULTS: 44 Leiomyosarcoma (LMS), 7 low-grade endometrial stromal sarcoma (LG-ESS), 4 high-grade ESS and 2 undifferentiated US patients were identified. The median age at time of diagnosis was 51.0 years (range 18-83). The median follow-up time was 35 months. PFS for the total cohort was 14.0 (95%-Confidence-Interval (CI) 9.7-18.3) and OS 36.0 months (95%-CI 22.1-49.9). Tumor pathology was prognostically significant for OS with LG-ESS being the most favorable (mean OS 150.3 months). In the multivariate analysis, patients over 52 years showed a four times higher risk for tumor recurrence (hazard ratio (HR) 4.4; 95%-CI 1.5-12.9). Progesterone receptor negativity was associated with a two times higher risk for death (HR 2.8; 95%-CI 1.0-7.5). For LMS patients age ≥ 52 years (p = 0.04), clear surgical margins (p = 0.01), FIGO stage (p = 0.01) and no application of chemotherapy (p = 0.02) were statistically significant factors for OS. CONCLUSION: Tumor histology, age at time of diagnosis and progesterone receptor status were prognostic factors for US. Unfavorable OS in LMS patients was associated with advanced FIGO stage, suboptimal cytoreduction and application of chemotherapy.

Subspecialty training in Europe: a report by the European Network of Young Gynaecological Oncologists.

BACKGROUND: ESGO (European Society of Gynaecological Oncology) and partners are continually improving the developmental opportunities for gynaecological oncology fellows. The objectives of this survey were to evaluate the progress in the infrastructure of the training systems in Europe over the past decade. We also evaluated training and assessment techniques, the perceived relevance of ENYGO (European Network of Young Gynaecological Oncologists) initiatives, and unmet needs of trainees. METHODOLOGY: National representatives of ENYGO from 39 countries were contacted with an electronic survey. A graduation in well/moderately/loosely-structured training systems was performed. Descriptive statistical analysis and frequency tables, as well as two-sided Fisher's exact test, were used. RESULTS: National representatives from 33 countries answered our survey questionnaire, yielding a response rate of 85%. A national fellowship is offered in 22 countries (66.7%). A logbook to document progress during training is mandatory in 24 (72.7%) countries. A logbook of experience is only utilized in a minority of nations (18%) for assessment purposes. In 42.4% of countries, objective assessments are recognized. Trainees in most countries (22 (66.7%)) requested additional training in advanced laparoscopic surgery. 13 (39.4%) countries have a loosely-structured training system, 11 (33.3%) a moderately-structured training system, and 9 (27.3%) a well-structured training system. CONCLUSION: Since the last publication in 2011, ENYGO was able to implement new activities, workshops, and online education to support training of gynaecological oncology fellows, which were all rated by the respondents as highly useful. This survey also reveals the limitations in establishing more accredited centers, centralized cancer care, and the lack of laparoscopic training.

Ovarian conservation in a patient with a large ovarian cyst and adnexal torsion - a confirmatory video with intravenous indocyanine green.

OBJECTIVE: To share our experience of intravenous indocyanine green (ICG) application during conservative ovarian surgery in a young patient with adnexal torsion, a large ovarian cyst, and apparent ovarian necrosis. DESIGN: This confirmatory video of ovarian reperfusion uses footage from the laparoscopic treatment and ICG application in a young patient with adnexal torsion and apparent necrosis. SETTING: Academic, multisite medical center. PATIENT(S): A 24-year-old patient with a 12-cm dermoid cyst, adnexal torsion, and apparent tissue necrosis. INTERVENTION(S): Five milligrams intravenous ICG, de-torsion, ovarian cystectomy, and ovarian reconstruction. The patient approved the ICG off-label use. MAIN OUTCOME MEASURE(S): Ovarian preservation and perioperative morbidity. RESULT(S): This video demonstrates the surgical treatment of a patient with adnexal torsion. The perfusion patterns before and after the surgical treatment, i.e., cyst de-torsion and cyst removal are documented using intravenous ICG. The perfusion patterns guided the surgeon to perform ovarian conservation despite apparent initial ischemia. The patient recovered well, and no postoperative 30-day morbidity occurred. CONCLUSION(S): Intraoperative subjective overestimation of the true ovarian ischemia may lead to unnecessary oophorectomy. Per the American College of Obstetrics and Gynecology recommendation, patients with adnexal torsion should be treated surgically with ovarian conservation regardless of the appearance of the ovary. As demonstrated, ovaries reperfuse despite multiple twists along the infundibulopelvic pedicle, apparent necrosis, and large cysts. Unilateral salpingo-oophorectomies are avoidable even in these cases.

Utilization and Outcomes of Sentinel Lymph Node Biopsy for Early Endometrial Cancer.

OBJECTIVE: To examine trends, characteristics, and oncologic outcomes of sentinel lymph node biopsy for early endometrial cancer. METHODS: This observational study queried the National Cancer Institute's Surveillance, Epidemiology, and End Results Program by examining 83,139 women with endometrial cancer who underwent primary hysterectomy with nodal evaluation for T1 disease from 2003 to 2018. Primary outcome measures were the temporal trends in utilization of sentinel lymph node biopsy and patient characteristics associated with sentinel lymph node biopsy use, assessed by multivariable binary logistic regression models. Secondary outcome measure was endometrial cancer-specific mortality associated with sentinel lymph node biopsy, assessed by propensity score inverse probability of treatment weighting. RESULTS: The utilization of sentinel lymph node biopsy increased from 0.2 to 29.7% from 2005 to 2018 (P<.001). The uptake was higher for women with endometrioid (0.3-31.6% between 2005 and 2018) compared with nonendometrioid (0.6-21.0% between 2006 and 2018) histologic subtypes (both P<.001). In a multivariable analysis, more recent year surgery, endometrioid histology, well-differentiated tumors, T1a disease, and smaller tumor size were independently associated with sentinel lymph node biopsy use (P<.05). Performance of sentinel lymph node biopsy was not associated with increased endometrial cancer-specific mortality compared with lymphadenectomy for endometrioid tumors (subdistribution hazard ratio [HR] 0.96, 95% CI 0.82-1.13) or nonendometrioid tumors (subdistribution HR 0.85, 95% CI 0.69-1.04). For low-risk endometrial cancer, the increase in sentinel lymph node biopsy resulted in a 15.3 percentage-point (1.4-fold) increase in surgical nodal evaluation by 2018 (expected vs observed rates, 37.8 vs 53.1%). CONCLUSION: The landscape of surgical nodal evaluation is shifting from lymphadenectomy to sentinel lymph node biopsy for early endometrial cancer in the United States, with no indication of a negative effect on cancer-specific survival.
