Abstract

Objective: The role of secondary cytoreductive surgery (SCS) in platinum-sensitive recurrent ovarian cancer (PSROC) is still controversial. We investigated the role of SCS in PSROC patients with BRCA1/2 mutation (BRCAmut) who received platinum-based chemotherapy followed by olaparib maintenance. Methods: This is a case-control study. Patients with first PSROC admitted to our Gynecologic Oncology Unit between 2014 and 2018 were identified. Main eligibility criteria: positive BRCA1/2 germline or somatic mutation status and olaparib maintenance at primary recurrence after response to platinum-based chemotherapy. Cases were those who received SCS followed by medical treatment (SCS-CT-OLA, group 1), controls were those who received medical treatment alone (CT-OLA, group 2). Results: Overall, 46 patients were identified; 23 (50%) BRCAmut women undergoing SCS followed by platinum-based chemotherapy and olaparib maintenance were matched with 23 (50%) BRCAmut women who only received medical treatment. Groups were well balanced: no statistical differences were found with regard of age, mutational status, treatment's approach at diagnosis, timing and patterns of disease presentation at recurrence. Median time to first subsequent therapy (TFST) was significantly longer in the SCS-CT-OLA than in the CT-OLA group (42 months vs 16 months; p = 0.05). Also, SCS-CT-OLA patients had the best post-recurrence survival (PRS), with a 3-year PRS of 79% in SCS-CT-OLA group versus 42% in CT-OLA group (p = 0.02). Conclusions: SCS increases TFST and PRS in PSROC patients with BRCAmut candidate for olaparib maintenance after platinum-based chemotherapy. Prospective studies are needed. In the era of personalized medicine, indication to SCS should be individualized.
