Gleason 3 would thus be the lowest grade assigned if no higher grade patterns are identified. Gleason scores have often been categorized into groups that show similar biologic behavior: Most studies addressing the issue whether the modified system correlated with clinical stage and patient outcome better than the original scheme have reached positive conclusions, despite occasional dissent 23 Interestingly, the latter two groups also showed significant differences.

However, other studies appeared to show no significant change in level of agreement between scores of needle biopsies and subsequent radical prostatectomy specimens Prostate specific antigen cannot distinguish stage T1a A1 prostate cancer from benign prostatic hyperplasia.
