Niraparib Maintenance Therapy in Patients with Platinum-Sensitive Recurrent Ovarian Cancer: Real-World Experience at Hospitals in Spain.

Background: The reported benefit of poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance in patients with newly diagnosed and platinum (Pt)-sensitive recurrent ovarian cancer (OC) included in randomized clinical trials needs to be corroborated in a less selected population.

Objective: The aim is to increase the evidence on niraparib in a real-world setting.

Methods: This is a retrospective observational study including women with platinum-sensitive relapsed high-grade serous OC who started niraparib maintenance between August 2019 (marketing data, Spain) and May 2022.
