The role of transrectal aspiration biopsy in the diagnosis of prostatic cancer.

We reviewed our experience with transrectal aspiration biopsy during an 18-month period. This procedure was the sole technique used in 75 men and prostatic cancer was diagnosed in 19. Two of these patients were not treated because a core biopsy performed at another hospital was negative for carcinoma. Aspiration and transperineal core biopsies were performed in 62 other cases. The sensitivity of aspiration to diagnose prostatic cancer was 98 per cent (45 of 46 biopsies) compared to only 81 per cent (37 of 46) for the core biopsy method. No patient suffered a complication following the aspiration biopsy. These data further support the value of transrectal aspiration biopsy as a sensitive, easy to perform method for sampling an abnormal prostate. More widespread use of this technique in the United States should be encouraged.
