Twelve core group (105 participants): transrectal ultrasound guided prostate biopsy, after troncular bilateral anesthesia with 10 ml of 1% lidocaine, using a 7.5 Hz probe, an 18-gauge trucut needle, and a spring-loaded biopsy gun. Dividing the prostate in apex, middle, and base, right and left side, one paramedian core and one lateral core of each segment was sampled.
Twenty core group (91 participants): transrectal ultrasound guided prostate biopsy, after troncular bilateral anesthesia with 10 ml of 1% lidocaine, using a 7.5 Hz probe, an 18-gauge trucut needle, and a spring-loaded biopsy gun. Dividing the prostate in apex, middle, and base, right and left side, one paramedian core and one lateral core of each segment was sampled and two additional cores were obtained from the prostate middle and base segments on each side.

Z12.5
|
Primary Outcome(s)
|
Higher prostate cancer detection rate using a 20-core biopsy protocol than the standard 12-core biopsy protocol, based on the histological analysis of cores.
|
Secondary Outcome(s)
|
Higher clinically insignificant prostate cancer detection rate using a 20-core biopsy protocol than the standard 12-core biopsy protocol, based on the histological analysis of cores.
Clinically insignificant cancers: maximum of three positive cores, greatest percentage of cancer of 50% of core length, and Gleason score of 6 or less.
|
Higher prostate cancer detection rate using a 20-core biopsy protocol than de standard 12-core biopsy protocol, based on the histological analysis of cores in patients with prostatic-specific antigen lower than 6 ng/ml, prostatic volume lower than 40 cm³ and/or younger than 60 years old.
