OBJECTIVE: To investigate individual and contextual factors contributing to overall prostate cancer (PCa) survival in Florida.
METHODS: A random sample of 6,457 PCa cases diagnosed between 10/1/2001 and 12/31/2007 was extracted from Florida Cancer Data System. Comorbidity was computed following Elixhauser Index. Survival probability curve was generated using Kaplan-Meier method. The Wei, Lin, and Weissfel model was used for the multivariate analysis.
RESULTS: Older age at diagnosis was associated with shorter time to death. Current smokers had a higher hazard rate than non-current smokers. Higher hazard of overall mortality was associated with being diagnosed with advanced stage compared with localized stage and having poorly-differentiated tumor compared with well-moderately differentiated tumor. No definitive treatment, radiation alone, and hormone alone were significantly associated with elevated hazard rate compared with surgery. Fifteen comorbidities were significantly associated with shorter time-to-death.
CONCLUSIONS: Effective control of comorbidity in PCa patients should help improve life expectancy and lead to prolonged survival.
