## Background: The authors previously found that, although the total percentage of prostate needle biopsy cores with carcinoma was a significant predictor of prostate specific antigen (psa) failure among men undergoing radical prostatectomy (rp), there was a trend toward a lower risk of recurrence in patients with positive bilateral biopsies, suggesting that high-volume, unilateral disease was a worse predictor of outcome than an equivalent number of positive cores distributed over two lobes. in the current study, the authors sought to compare the total percentage of cores with carcinoma directly with the percentage of cores from the more involved or dominant side of the prostate with carcinoma for their ability to predict outcome among men who underwent rp. ## Methods: A retrospective survey of 535 patients from the shared equal access regional cancer hospital database who underwent rp at 4 different equal-access medical centers between 1988 and 2002 was undertaken. the total percentage of cores positive was compared with the percentage of cores positive from the dominant and nondominant sides for their ability to predict biochemical recurrence after rp. the best predictor then wa
