Methods: Multicenter, retrospective, epidemiological, observational real-world study reviewing clinical records from 277 patients diagnosed with AOC between January 2008 and December 2010 who were treated and followed in 31 Spanish hospitals belonging to the Spanish Ovarian Cancer Research Group (GEICO). Survival curves were estimated by Kaplan-Meier and differences analyzed by the log-rank test. Results: Median age at diagnosis was 62 years (range 26-96), 62% of patients had a high-grade serous carcinoma, and 64% and 21% of patients had stage IIIC and stage IV disease, respectively. Overall, 46% of patients underwent primary debulking surgery (PDS), with complete cytoreduction in 63% of procedures, and 34% underwent interval debulking surgery, with complete cytoreduction in 71% of them. Overall, 96% of patients received at least one cycle of front-line chemotherapy. Recurrence occurred in 77% of patients, and 90% of them (69% of total) received a second line chemotherapy. Median progression-free survival (PFS) was 14 months (95% CI: 13-17) and median overall survival (OS) was 41 months (95% CI: 34-49). PDS and complete cytoreduction had a statistically significant correlation with PFS and OS. Conclusions: This retrospective study provides real-world data of clinical characteristics, therapeutic management, and outcomes in Spanish AOC patients. Primary debulking surgery and complete cytoreduction were favorable prognostic factors in this series.
