However, the effect of statin on cancer mortality in COPD patients is poorly documented. The study endpoint is to evaluate the impact of statin on cancer mortality of COPD patients.Methods:Based on a large pharmaceutical French database of the North area, a retrospective cohort study was conducted in order to evaluate the effect of statin on cancer mortality in COPD patients. Analysis, based on a Cox proportional hazards model with statin exposure handled as a time-dependent variable, included the 66 429 individuals 40 years old or more who had at least one pharmaceutical dispensation between 01/01/2000 and 05/11/2007. In this cohort, 9531 COPD patients were identified; 18.1% of COPD patients were considered exposed to statin.Findings:The overall death rate of COPD patients is 40.8%. The various causes accountable for COPD patients' death were: cardiovascular diseases for 33.7%, respiratory diseases for 33.7% and cancer for 24.8%. Statin treatment was significantly associated with a decrease of cancer mortality in COPD patients with estimates (hazard ratio [95% CI], p value) at 0.586 [0.465-0.739], p=<0.0001.Interpretation:It seems that statin delivery to COPD patient reduces the cancer death rate. However the result has to be checked out by prospective randomized studies. %U https://erj.ersjournals.com/content/erj/40/Suppl_56/P997.full.pdf
