Grading of the prostate carcinoma, cyto-histological correlations on 100 cases

Abstract

From January 1980 to December 1983, 154 patients underwent prostatic FNAB and histological control. The sensitivity of cytology was 85070, the specificity 68% and the predictive value of positive cases 83%. The cyto-histological correlation of the grading of the 100 prostatic carcinomas histologically confirmed (85 cytologically positive for carcinoma and 15 negative or uncertain) showed a predictive value of positive results of 58%, ranging from 42% for G3, 50% for G1 and 69% for G2. The usefulness of cytological grading is stressed to monitor the follow-up of those patients treated for prostatic carcinoma who, because of the advanced stage or age, were not surgically treated.
