PROSTATE CANCER IN PATIENTS WITH SCREENING SERUM PROSTATE SPECIFIC ANTIGEN VALUES LESS THAN 4.0 NG/DL: RESULTS FROM THE COOPERATIVE PROSTATE CANCER TISSUE RESOURCE

Abstract

Young (younger than 62 years) or white patients with screening serum PSA less than 4.0 ng/ml had smaller, lower grade tumors and lower recurrence rates than patients with PSA 4.0 ng/ml or greater. This was not true for those older than 62 years and for black men.
