Purpose:
Prostate cancer detection on standard sextant biopsy is considered inadequate. Various biopsy protocols have been introduced to improve cancer diagnosis. We report our experience with transperineal 12-core prostate biopsy.
Materials And Methods:
In a prospective study 650 patients underwent prostate specific antigen (PSA) measurement during a 15-month period, of whom 141 with PSA greater than 4 ng./ml. also underwent transperineal 12-core prostate biopsy using the fan technique. Median PSA was 8 ng./ml. (range 4.1 to 5,000).
Results:
Prostate cancer was detected in 72 of the 141 patients (51%), including 44 of the 97 (45%) with PSA between 4.1 and 10 ng./ml. This incidence is higher than previously reported in the literature using other biopsy techniques. Disease was low grade Gleason 2 to 4 in 4 cases (5%), intermediate grade Gleason 5 to 6 in 26 (35%) and high grade Gleason 7 to 10 in the remaining 42 (60%).
Conclusions:
A high cancer detection rate is achieved by 12-core transperineal prostate biopsy. Most tumors represent clinically significant cancer. Further randomized trials are required to confirm these data.
