International audience. Background: In ovarian cancer, the increased rate of radical surgery comprising upper abdominal procedures has participated to improve overall survival (OS) in advanced stages by increasing the rate of complete cytoreductions. However, in the context of non-resectability, it is unclear whether radical surgery should be considered when it would lead to microscopic but visible disease (≤1 cm). We aimed to compare the survival outcomes among patients with incomplete cytoreduction according to the extent of surgery.Methods: Overall, 148 patients presenting with advanced stage ovarian carcinomas were included in this retrospective study, regardless of treatment schedule. These patients were stratified according to the extent of surgery (standard or radical). Complete cytoreduction at the time of debulking surgery could not be carried out in all cases.Results: Among our study population (n = 148), 96 patients underwent standard procedures (SPs) and 52 underwent radical surgeries (RP). Patients in the SP group had a lower Peritoneal Index Cancer (PCI) at baseline (12.6 vs. 14.9; p = 0.049). After PCI normalization, we observed similar OS in the SP and RP groups (39.7 vs. 43.1 months; p = 0.737), while patients in the SP group had a higher rate of residual disease >10 mm (p < 10(-3)). Patients in the RP group had an increased rate of relapse (p = 0.005) but no difference in disease-free survival compared with the SP group (22.2 for SP vs. 16.3 months; p = 0.333). Residual disease status did not impact survival outcomes.Conclusions: In the context of non-resectable, advanced stage ovarian cancer, standard surgery seems as beneficial as radical surgery regarding survival outcomes and should be considered to reduce surgery-associated morbidity.
