Prostate Cancer Survival and Mortality according to a 13-year retrospective cohort study in Brazil: Competing-Risk Analysis

ABSTRACT: Objective: To analyze cancer-specific mortality (CSM) and other-cause (OCM) among patients with prostate cancer that initiated treatment in the Brazilian Unified Health System (SUS), between 2002 2010, Brazil. Methods: Retrospective observational study used National Oncological Database, which was developed by record-linkage techniques to integrate data from SUS Information Systems, namely: Outpatient (SIA-SUS), Hospital (SIH-SUS), Mortality (SIM-SUS). Cancer-specific survival probabilities were estimated time elapsed date of first until patients’ deaths or end study, 2015. The Fine-Gray model for competing risk estimate factors associated death. Results: Of 112,856 studied patients, average age 70.5 years, 21% died due cancer, 25% other causes. Specific 160 months 75%, 67%. For CSM, main death were: stage IV (AHR = 2.91; 95%CI 2.73 - 3.11), systemic 2.10; 2.00 2.22), combined surgery 2.30, 2.18 2.42). As OCM, comorbidities. Conclusion: analyzed older mainly causes, probably presence comorbidities tumor.
