Severity of cardiovascular disease and health-related quality of life in men with prostate cancer: a longitudinal analysis from CaPSURE

Abstract

ObjectiveTo evaluate the influence of comorbid cardiovascular disease severity on health-related quality of life (HRQL) in men treated with radical prostatectomy (RP) or radiotherapy (RT) for early stage prostate cancer.MethodsSubjects (n = 830) with non-metastatic disease who had been diagnosed in 2000–2002 were drawn from Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE). We evaluated the influence of cardiovascular disease (CVD) severity on generic and disease-specific HRQL before and 6, 12, 18, and 24 months after treatment with RP or RT. HRQL was measured with the SF-36 and the UCLA Prostate Cancer Index.ResultsMen with moderate (n = 193) or severe (n = 51) cardiovascular disease had worse pre-treatment HRQL than did men without CVD (n = 293) (P < 0.01); HRQL scores were worse in men referred for RT. During 24 months of follow-up, men with moderate or severe CVD had worse SF-36 physical and mental component summaries and worse bowel function at all time points (P < 0.05). Men with severe CVD also experienced a slower recovery in physical function (P = 0.03) and sexual functioning (P = 0.02) than did men without CVD.ConclusionsProstate cancer patients with moderate to severe CVD have worse HRQL during follow-up. Those with severe CVD recover their physical and sexual functioning more slowly after treatment.
