ObjectiveObservational studies suggest that statin therapy for cardio-protection is associated with improved survival in cancer patients. We sought to evaluate the impact of statin treatment on ovarian cancer survival in a nationally representative elderly population.MethodsThe linked Surveillance, Epidemiology, and End Results (SEER) registries and Medicare claims data on patients diagnosed with epithelial ovarian cancer in 2007-2009 were used to extract data on statin prescription fills, population characteristics, primary treatment, comorbidity and survival. Cox regression models were used to examine the association between statin treatment and overall survival.ResultsAmong the 1431 ovarian cancer patients who underwent surgical resection, 609 (42.6%) filled prescriptions for statin. The majority of statin-users (89%) were prescribed a lipophilic formulation. Mean overall survival among statin-users was 32.3months compared to 28.8months for non-users (p<0.0001). A 34% reduction in death was associated with statin therapy, independent of age, race, neighborhood median household income, stage, platinum therapy and comorbid conditions (HR=0.66, 95% CI 0.55-0.81). Improved overall survival with statin use was observed for both serous (HR=0.69, 95% CI 0.54-0.87) and non-serous (HR=0.63, 95% CI 0.44-0.90) histologies. When statin treatment was categorized by lipophilicity and intensity, a significant survival benefit was limited to lipophilic statin users and those who took statins of moderate intensity.ConclusionsThis SEER-Medicare analysis demonstrates improvement in overall survival with lipophilic statin use after surgery in elderly patients with epithelial ovarian cancer. A clinical trial to evaluate the impact of statin treatment in ovarian cancer survival is warranted.Copyright © 2017 Elsevier Inc. All rights reserved.
