The association between presentation PSA and race in two sequential time periods in prostate cancer patients seen at a university hospital and its community affiliates.

Abstract

We sought to determine whether African American men diagnosed with prostate cancer in the prostate-specific antigen (PSA) era differed in initial presenting serum PSA levels (iPSA) compared to white men. Recent retrospective studies have demonstrated higher iPSA within the African American men than in white men at the time of diagnosis, suggestive of more advanced disease in African American men. Both biologic differences and/or sociologic factors have been postulated as explaining the noted differences in iPSA. We reviewed our institution's PSA-era experience to determine any association between race and iPSA.
