In the first clinical study of a new blood protein associated with prostate cancer, researchers have found that the marker, called EPCA or early prostate cancer antigen, can successfully detect prostate cancer in its earliest stages. At the same time, the marker successfully avoids the problem of false positive results that plagues prostate-specific antigen (PSA) testing.

Study results appear in the May 15, 2005, issue of Cancer Research. The lead author is Robert H. Getzenberg, Ph.D., professor of urology and director of research at the James Buchanan Brady Urological Institute at Johns Hopkins.

The traditional two-step approach of PSA testing and digital rectal examination has helped doctors identify prostate tumors early, while the cancers can still be cured.
