Primary hormonal therapy for prostate cancer: experience with 135 consecutive PSA-ERA patients from a tertiary care military medical center.
The use of prostate specific antigen (PSA) in the 1990s has brought on a stage migration of prostate cancer. Despite that, many men have still presented with metastatic prostate cancer in the past decade. The use of primary hormone therapy in the PSA era at a tertiary care Army Medical Center is studied in this paper. Charts were reviewed of 135 men who were diagnosed with metastatic prostate cancer and treated with hormone therapy as a primary treatment between 1989 and 1995. Statistical analysis was used to determine significant predictor variables on the time to disease progression. In univariate analysis clinical stage, pretreatment alkaline phosphatase and nadir PSA values were significant predictors of time to progression. Race and type of treatment were not. In multivariate analysis the relative risk of progression was 3.2 for patients with an alkaline phosphatase >252 and 16.5 for patients with a nadir >2.0. This study supports the argument that racial disparities in prostate cancer outcomes are due to access to care. Furthermore, the survival rate for patients with D-2 disease is better than in the pre PSA studies. Clinical stage, pretreatment alkaline phosphatase and PSA nadir can be used to predict response for those men presenting with metastatic prostate cancer.
