Multiparametric magnetic resonance imaging (mpMRI)-targeted transrectal prostate biopsy (TBx) may better predict pathology at radical prostatectomy than systematic transrectal prostate biopsy (SBx).To assess concordance between biopsy and radical prostatectomy pathology in men undergoing a TBx as compared with those undergoing an SBx.Four electronic databases (Ovid MEDLINE, Ovid EMBASE, the Cochrane Library [Wiley], and EBSCHOHost) were searched from inception until July 2018. Studies were included if they were published after 2012, conducted both SBx and TBx, and compared the biopsy results with final pathology after radical prostatectomy for ≥50 patients. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized. Bias was appraised using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool.Our search yielded 10 studies including 1215 men. However, our inclusion criteria applied only to a proportion of men included in these studies. The median age was 65 yr and the median prostate-specific antigen level was 7.2 ng/ml. In the eight studies examining upgrading at prostatectomy, pathology from SBx was significantly more likely to be upgraded relative to TBx (odds ratio [OR] 2.47, 95% confidence interval [CI] 1.48-4.14, p =  0.001). We found no significant difference in downgrading (OR 1.13, 95% CI 0.48-2.67, p =  0.783) between TBx and SBx. For both biopsy-naïve men and men with a prior negative biopsy, results from SBx were more likely to be upgraded than TBx at prostatectomy (OR 1.6 [95% CI 1.02-2.27, p <  0.001] and OR 4.23 [95% CI 1.68-8.48, p =  0.003], respectively).Pathologic upgrading at prostatectomy was less likely with mpMRI-targeted biopsy versus systematic biopsy alone, without concurrent increase in downgrading. This increased accuracy should improve confidence in management decisions based on MRI-targeted biopsy pathology.We reviewed the ability of multiparametric magnetic resonance imaging -targeted biopsy to predict cancer grade at radical prostatectomy. We found that targeted biopsy provides more accurate assessment of Gleason score at prostatectomy than systematic biopsy.
