Abstract

Background. We evaluated the clinical impact of germline (g)BRCA1/2-mutation on initial disease presentation, surgical implications, surgical morbidity and survival in patients with advanced epithelial ovarian cancer (EOC) undergoing debulking surgery (DS). Methods. Data of all consecutive EOC patients with stage III/IV, high-grade serous disease and known gBRCA1/ 2 status (gBRCA;non-gBRCA), who underwent DS at our department between 01/2011 and 06/2019 were analyzed. Associations between gBRCA-status and severe postoperative complications and survival were analyzed. Results. gBRCA-status was determined in 50.1% (612/1221) of all patients. gBRCA was present in 21.9% (134/ 612). Significant differences were observed in terms of median age (p = 0.001) and histology (high-grade serous histology gBRCA: 98.5%, non-gBRCA 76.2%;p < 0.001). gBRCA-status had no impact on intraoperative disease presentation, surgical complexity or complete resection rate (gBRCA: 74.4%, non-gBRCA: 69.0%;p = 0.274). gBRCA-status was not predictive for severe postoperative complication (gBRCA: 12.0%, non-gBRCA: 19.1%;p = 0.082). Median PFS and OS was 31/22 and 71/53 months in patients with/without gBRCA-mutation, respectively. gBRCA was a significant prognostic factor for PFS (HR 0.57 p < 0.001) and for OS (HR 0.64, p = 0.048) after adjusting for established prognostic factors. Conclusions. gBRCA-status had no impact on initial disease presentation, surgical results or postoperative complications. gBRCA patients have a significantly longer PFS but the impact on the long term prognosis is unclear. Complete resection remains the most important prognostic factor in patients with EOC independent of gBRCA-status. (c) 2021 ELSEVIER. All rights reserved.
