Transrectal fine needle aspiration (FNA) and core biopsies were simultaneously taken from 68 patients with clinically suspected prostatic carcinoma (PCa) in a twenty two-month period. In nine FNA and two core biopsies, histopathologically 26 patients were diagnosed as PCa and the remaining 42 as benign prostatic hyperplasia (BPH). FNA alone revealed PCa in 24/26 (92,3%) patients, whereas core biopsy in 25/26 (96,2%) patients. There was one false-negative result for each method. The data from this study suggests that FNA is reliable in diagnosing PCa accurately.
