To compare the relative prognostic accuracy of the Gleason classification, the Whitmore staging, and the Broder grading systems, 111 patients with prostate cancer undergoing radical surgery were assessed utilizing these systems. The assessments were correlated with the presence or absence of disease six months to eight years after surgery. Of the three systems the Gleason classification system was the least accurate.
