    Abstract:
    Between October 1990 and June 1993, 112 patients underwent fine needle aspiration cytology and core needle biopsy of the prostate under transrectal ultrasonographic guidance. They were suspected of having prostatic cancer from the prostatic antigen level, digital rectal examination and/or transrectal ultrasonography. Twenty seven of the 112 cases (24%) were diagnosed with prostatic cancer. Their cytological diagnoses showed 22 class IV or V, 2 class III, and 3 class I or II. Efficiency, false negative rate and false positive rate were 86%, 11% and 0% in fine needle aspiration cytology. We could obtain sufficient samples for fine needle aspiration cytology in all cases. No severe complication was observed. However, we missed 3 patients, in fine needle aspiration cytology, who were strongly suspected of having prostatic cancer, and reexamination or additional core needle biopsy would have been necessary on 15 of the 112 patients (13%) who showed false negative or class III cytological results, if we had screened prostatic cancer only by fine needle aspiration cytology. In conclusion, fine needle aspiration cytology may not be as useful as core needle biopsy to screen prostatic cancer.
