Cancer core distribution in patients diagnosed by extended transperineal prostate biopsy

The results of our study have shown that transperineal approaches are appropriate for sampling from the anterior half of the prostate gland. In patients in whom the diagnosis of prostate cancer is suspected, we believe that systemic 22-core transperineal ultrasound-guided template prostate biopsy might be the next optional diagnostic step after an initial negative prostate biopsy.
