Prostate-Specific Antigen and Detecting Early Prostate Cancer: The Importance of Race and Patient Age
Although discovered more than 20 years ago, prostate-specific antigen (PSA) did not receive clinical attention until 1986. Since then, however, it has been the center of intense investigation at both the basic science and clinical levels. As a result, much has been learned about this glycoprotein, and today it must be considered the most useful tumor marker available for the diagnosis and management of prostate cancer (Oesterling 1991). It is superior not only to prostatic acid phosphatase but also to digital rectal examination (DRE).
