Fine needle aspiration biopsy of the prostate gland: our experience concerning 101 cases with histological follow-up.
Our experience concerning 605 fine needle aspiration (FNA) biopsies performed between 1985 and 1988 is reported. FNA specimens of the prostate gland were compared to histological material in 101 cases: 37 patients underwent suprapubic prostatectomy, 15 radical prostatectomy, 28 transurethral resection, and 21 core needle biopsies. Adenocarcinoma was correctly diagnosed by using cytology in 39 out of 40 cases; benign prostatic hypertrophy was confirmed by histology in 54 out of 57 cytologically benign cases. The absolute sensitivity of the FNA biopsy was 98.2%; specificity was 98.1%; efficiency was 96%; and false negative rate was 6.6%. Our data support the value of transrectal aspiration biopsy as a precise and easy method for diagnosing prostatic cancer; the low false negative rate and the high number of correct diagnoses underline the great accuracy of the method.
