Therefore, we identified the prebiopsy parameters that may be predictive of prostate cancer in black and white men. Materials and Methods: From January 2000 to July 2004, 914 consecutive men undergoing prostate needle biopsy were prospectively examined by a single urologist. Urinary symptoms were measured by AUASS. Prebiopsy parameters recorded were PSA, free PSA, DRE, age, race, biopsy history, prostate volume, TRUS lesion and AUASS. Results: Prostate biopsy was performed in 914 men with a mean age of 63.9 years. Mean PSA in the entire cohort was 11.2 ng/ml (median 5.8). Abnormal TRUS and abnormal DRE were found in 37% and 52% of men, respectively. Mean AUASS was 9.6. The overall positive biopsy rate was 37%. In black and white men the positive biopsy rate was 44% and 34%, respectively. Analysis of AUASS indicated that 47% of patients had low symptom scores (less than 7), 39% had moderate scores (8 to 19) and 14% had severe scores (20 to 35). Multivariate analysis revealed that PSA was an independent predictor of positive biopsy in black but not in white men (p = 0.001 and 0.79, respectively). Multivariate analysis also showed that race alone was an independent predictor of positive prostate biopsy (p = 0.013). Conclusions: PSA remains an independent predictor of positive prostate biopsy on multivariate analysis. Other independent predictors are black race, age, low AUASS, prostate volume, abnormal DRE, no previous biopsy and abnormal TRUS. In the black group low AUASS, PSA, no previous biopsy and DRE were unique independent predictors, while in the white group age and abnormal TRUS were unique predictors.
