Introduction/Background The primary objective of this study was to analyze the impact of comorbidities, postoperative complications and center volume on overall survival in a real-life cohort of ovarian cancer patients in France.

Methodology All French women aged 18 years or over, with an ovarian cancer newly diagnosed between January 2013 and December 2019, registered in the general health insurance coverage plan were included in the cohort. Ovarian cancer treatments, comorbidities, postoperative complications and death were extracted from hospital discharge reports. The characteristics of the centers were also collected.

Results We included 29,879 patients with ovarian cancer in the cohort. The median age was 66 [57–74] years, and 24,783 (82.9%) presented an advanced stage at diagnosis (FIGO IIB-IVB). A total of 16,048 (53.7%) patients had at least one comorbidity at the time of diagnosis, with mainly hypertension (n=6,800) and obesity (n=2,505). Patients received primary surgery, interval surgery, or chemotherapy alone in 31.5%, 30.4%, and 38.1% of cases, respectively. A total of 3,031 (16.1%) patients presented a postoperative complication Clavien-Dindo III or more within 90 days of cytoreduction surgery, mainly digestive (60.4%). For advanced stage, the median overall survival was 47 [45.9–48] months. The number of comorbidities, the occurrence of a complication and low center volume had a significant negative impact on the overall survival.

Conclusion Real-life data give the opportunity to study the key health indicators in ovarian cancer. In order to improve quality of care, a personalization of the care pathway for patients with comorbidities and at risk of postoperative complications must be carried out.
