Randomized Study of Systematic Biopsy Versus Magnetic Resonance Imaging and Targeted and Systematic Biopsy in Men on Active Surveillance (ASIST): 2-year Postbiopsy Follow-up

The initial report from the ASIST trial showed little benefit from targeted biopsy for men on active surveillance (AS) for prostate cancer. Data after 2-yr follow-up are now available for analysis. To determine if there was a difference in the AS failure rate in a 2-yr follow-up period among men undergoing magnetic resonance imaging (MRI) before initial confirmatory biopsy (CBx) compared to those who did not. This is the 2-yr post-CBx follow-up...
