title: [Cytologic diagnosis of prostatic carcinoma by transrectal prostatic aspiration biopsy].
abstract: Since October 1982, 500 cases of transrectal fine needle aspiration biopsy have been done. Among them, 486 cases (97.2%) got prostate epithelium enough for diagnosis but 14 cases (2.8%) failed. The cytologic results showed prostatic cancer in 100 cases (20.5%), bladder cancer with metastasis to prostate in 7 cases (1.4%), suspicious cancer in 4 cases (0.82%), hyperplasia of prostate 251 cases (51.64%), normal prostate 104 cases (21.3%), tuberculosis one case (0.2%), lithiasis one case (0.2%), purulent prostatitis 4 cases (0.82%), granulomatous prostatitis 6 cases (1.23%), and insufficient epithelium for diagnosis in 8 cases (1.64%). In this series, there were one false positive and two false negative by Franzen's technique. Among 41 cases received further treatment, 35 prostate specimen were available for regular pathological study. The consistent rate between pathological and cytologic diagnosis was 85.4%. In a word, transrectal prostatic aspiration is an outstanding safe and practical method for the diagnosis of prostate cancer.
