Operable Prostatic Carcinoma: Correlations Among Clinical Stage, Pathological Stage, Gleason Histological Score and Early Disease-Free Survival

We investigated the relationships among clinical and pathological stages, Gleason histological score and early disease-free survival of 75 patients with localized prostatic carcinoma treated by radical prostatectomy. Carcinoma was confined histologically to the prostate in 81 per cent of the patients with clinical stage A2, 79 per cent with B1N, 38 per cent with B1 and 0 per cent with B2 tumors. The Gleason score correlated directly with clinical and pathological stages, estimated extent of intraprostatic tumor and invasive capacity of the primary tumor. Of the tumors with a Gleason score of 8 or more 81 per cent extended beyond the prostatic capsule. Of 12 patients who suffered distant metastases 9 had tumors that extended beyond the prostatic capsule and 5 had tumors with Gleason scores of 8 or more.
