PURPOSE: To analyze the association between prostatic proliferative inflammatory atrophy finding in negative prostate biopsies and future detection of prostate cancer (PCa) and its aggressiveness in men subjected to repeat biopsies, due to persistent suspicion of PCa. MATERIALS AND METHODS: Prospective and observational study of 474 men scheduled to repeated PBs. Assessment of PIA and its extension in the previous biopsy. PCa detection rate and tumor aggressiveness. Age, serum total PSA, free PSA, percent free PSA (%fPSA), digital rectal exam (DRE), prostate volume (PV), PSA density (PSAD), PSA kinetics (PSAV and PSADT) findings of PIA and HGPIN, and number of affected cores in previous PBs were included in the univariate and multivariate analysis. Aggressive tumors were considered when any Gleason pattern 4 was found. RESULTS: PCa was detected in 133 men (28.1%). Age, serum total PSA, %fPSA, PV, PSAD, PSAV, PSADT, and PIA finding were significantly associated to PCa detection. However, only age, OR: 1.06 (95%CI: 1.03–1.10), P < 0.01; DRE, OR: 1.76 (95%CI: 1.05–2.92), P = 0.03; %fPSA, OR: 0.96 (95%CI: 0.93–0.99), P = 0.03; PV, OR: 0.98 (95%CI: 0.97–0.99) and PIA finding, OR: 0.49 (95%CI: 0.29–0.83), P < 0.01, were independent predictors of PCa detection. PCa was found in 18% of 159 men with previous PIA finding while in 33% of 315 men without previous PIA (P < 0.01). None of the studied parameters including PIA in the previous biopsy were related with subsequent PCa aggressiveness. CONCLUSIONS: PIA finding in negative biopsies correlates with a decreased frequency of detecting PCa in men with persistent suspicion of PCa. The aggressiveness of future detected tumors was not associated with previous PIA finding. Prostate 76:1501–1506, 2016. © 2016 Wiley Periodicals, Inc.
