Predictors of Unfavourable Repeat Biopsy Results in Men Participating in a Prospective Active Surveillance Program

Active surveillance (AS) protocols for low-risk prostate cancer (PCa) generally include repeat prostate biopsies at predefined follow-up intervals.To study the outcome of routinely obtained 1-yr repeat biopsies and factors predicting reclassification to higher risk, to contribute to risk stratification for men on AS.We analysed men with low-risk PCa (clinical stage ≤ T2, prostate-specific antigen (PSA) ≤ 10 ng/ml, PSA density <0.2 ng/ml per...
