Objective: To evaluate whether biopsy cores taken via a transrectal approach from the anterior apical region of the prostate in a repeat-biopsy population can result in an increased overall cancer detection rate and in more accurate assessment of the Gleason score.
Patients And Methods: The study was a prospective, randomised (end-fire vs side-fire ultrasound probe) evaluation of 288 men by repeat transrectal saturation biopsy with 28 cores taken from the transition zone, base, mid-lobar, anterior and the anterior apical region located ventro-laterally to the urethra of the peripheral zone.
Results: The overall prostate cancer detection rate was 44.
Background: Patients with prostate cancer may present with metastatic or recurrent disease despite initial curative treatment. The propensity of metastatic prostate cancer to spread to the bone has limited repeated sampling of tumor deposits. Hence, considerably less is understood about this lethal metastatic disease, as it is not commonly studied.

Objective: Our aim was to study the clinical staging significance of PCA3 to identify pathologic favorable and/or unfavorable features in the RP specimen.
Design, Setting, And Participants: Complete retrospective clinical and pathologic data of consecutive men who had undergone RP from three tertiary referral centers including preoperative PCA3 scores (n=305) and computer-assisted planimetrically measured tumor volume data (n=160) were available.
