This study provides a comprehensive description of clinicopathological and therapeutic characteristics of BRCA-mutated high-grade epithelial ovarian cancers (HGEOCs) based on robust data from the ESME database. It offers important findings regarding the natural disease history of this specific patient population.
Simple Summary BRCA-mutated high-grade epithelial ovarian cancers represent a specific subset of gynecological malignancies. Real-world comprehensive data have been elusive to date. As such, we conducted a comprehensive description of clinicopathological and therapeutical characteristics via the Epidemiological Strategy and Medical Economics (ESME) data warehouse, which collects data from 18 French comprehensive cancer centers from the Unicancer network. This led to useful findings regarding the natural disease history of these patients in clinical practice, prior to the advent of poly-ADP ribose polymerase inhibitors. Background: In spite of the frequency and clinical impact of BRCA1/2 alterations in high-grade epithelial ovarian cancer (HGEOC), real-world information based on robust data warehouse has been scarce to date. Methods: Consecutive patients with BRCA-mutated HGEOC treated between 2011 and 2016 within French comprehensive cancer centers from the Unicancer network were extracted from the ESME database. The main objective of the study was the assessment of clinicopathological and treatments parameters. Results: Out of the 8021 patients included in the ESME database, 266 patients matching the selection criteria were included. BRCA1 mutation was found in 191 (71.8%) patients, while 75 (28.2%) had a BRCA2 mutation only; 95.5% of patients received a cytoreductive surgery. All patients received a taxane/platinum-based chemotherapy (median = six cycles). Complete and partial response were obtained in 53.3% and 20.4% of the cases, respectively. Maintenance therapy was administered in 55.3% of the cases, bevacizumab being the most common agent. After a median follow up of 51.7 months, a median progression-free survival of 28.6 months (95% confidence interval (CI) [26.5; 32.7]) and an estimated 5-year median overall survival of 69.2% (95% CI [61.6; 70.3]) were reported. Notably, BRCA1- and BRCA2-mutated cases exhibited a trend towards different median progression-free survivals, with 28.0 (95% CI [24.4; 32.3]) and 33.3 months (95% CI [26.7; 46.1]), respectively (p-value = 0.053). Furthermore, five-year OS for BRCA1-mutated patients was 64.5% (95% CI [59.7; 69.2]), while it was 82.5% (95% CI [76.6; 88.5]) for BRCA2-mutated ones (p-value = 0.029). Conclusions: This study reports the largest French multicenter cohort of BRCA-mutated HGEOCs based on robust data from the ESME, exhibiting relevant real-world data regarding this specific population.
