Serum BPSA may distinguish BPH from prostate Ca

San Francisco--Serum BPSA, an antigen enriched in the nodular transition zone tissue in BPH, appears to be a better predictor of clinically significant prostate enlargement than PSA or free PSA. This finding and complementary data, by researchers from the Scott Department of Urology, Baylor College of Medicine, Houston, lay the groundwork for further study that will determine the antigen's potential to distinguish between BPH and prostate cancer.
