Abstract: OBJECTIVE: To identify factors associated with increased 30-day mortality after advanced ovarian cancer debulking among elderly women. METHODS: A database linking Medicare records with the Surveillance, Epidemiology, and End Results (SEER) data was used to identify a cohort of 5,475 women aged 65 and older who had primary debulking surgery for stage III or IV epithelial ovarian cancer (diagnosed 1995-2005). Women were stratified by acuity of hospital admission. Multivariable analysis was performed to identify patient-related and treatment-related variables associated with 30-day mortality. RESULTS: Five thousand four hundred seventy-five women had surgery for advanced ovarian cancer, and the overall 30-day mortality was 8.2%. Women admitted electively had a 30-day mortality of 5.6% (251 of 4,517), and those admitted emergently had a 30-day mortality of 20.1% (168 of 835). Advancing age, increasing stage, and increasing comorbidity score were all associated with an increase in 30-day mortality (all P<.05) among elective admissions. A group of women at high risk admitted electively included those aged 75 or older with stage IV disease and women aged 75 or older with stage III disease and a comorbidity score of 1 or more. This group had an observed 30-day mortality of 12.7% (95% confidence interval 10.7%-14.9%). CONCLUSION: Age, cancer stage, and comorbidity scores may be helpful to stratify electively admitted patients based on predicted postoperative mortality. If validated in a prospective cohort, then these factors may help identify women who may benefit from alternative treatment strategies. LEVEL OF EVIDENCE: II.
