PARP inhibitors as maintenance therapy in ovarian cancer after platinum-sensitive recurrence: real-world experience from the Unicancer network.
Observational study in The oncologist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03275298 (Epidemiological Strategy and Medical Economic), which is not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundBased on results of randomized clinical trials, polyADP-ribose polymerase inhibitors (PARPi) have become the standard of care in patients with platinum-sensitive recurrent ovarian cancer (OvC) in patients responding to platinum chemotherapy. However, little is known about their impact on survival in a real-world setting. PATIENTS AND
methodsThis retrospective French multicenter observational study included women with platinum-sensitive recurrent OvC (not limited to the first platinum-sensitive relapse) receiving PARPi as maintenance after response to platinum-based chemotherapy. They were compared to patients with similar characteristics undergoing observation after chemotherapy completion. Data were collected in the Ovarian Cancer Epidemiological Strategy and Medical Economics (ESME-OC) database between 2011 and 2021. We explored progression-free survival (PFS) and overall survival (OS) benefits with PARPi maintenance.
resultsOne hundred and twenty-three patients matching the selection criteria were included in the PARPi group and 397 patients in the control group. Median PFS was 19.9 months (95CI [15.0-21.9]) in the PARPi group vs 13.4 months (95CI [11.8-15.0]) in the control group, with a HR = 0.71 (95CI [0.55-0.93]), P = .01). Median OS was 82.0 months (95CI [48.6-Not Estimable]) in the PARPi group vs 44.7 months (95CI [38.8-53.7]) in the control group (HR = 0.47, 95CI [0.30-0.74], P < .001). Multivariate analyses including performance status, histological subtype, achievement of cytoreductive surgery at relapse, and platinum-free interval, confirmed the independent prognostic impact of PARPi treatment.
conclusionThis first national study focusing on the efficacy of PARPi in a real-world population shows similar benefits than in randomized clinical trials, supporting their use in clinical routine practice. DATABASE REGISTRATION: clinicaltrials.gov Identifier NCT03275298.
