The efficacy of additional cores from cancer-suspicious lesions by transrectal ultrasound (TRUS) for the detection of prostate cancer (PCa) was assessed.
Data were collected from 4144 men who underwent systematic 12-core biopsy with no cancer-suspicious lesions (Group A: 3256 cases) or 13- or more-core (systematic 12 core + additional cores) biopsy with cancer-suspicious lesions (Group B: 888 cases) on TRUS-guided biopsy.
