Mp49-18 Detection of Clinically Significant Prostate Cancer Using Cognitive Versus Software-Based Mri-Targeting During Transperineal Prostate Biopsy: A Multi-Institutional Analysis

You have accessJournal of UrologyProstate Cancer: Detection however, prior analyses have not accounted for the impact of TP-B indication (biopsy naïve (BN), prior negative biopsy (PNB), active surveillance (AS)). We examined a large, multi-institutional cohort of men to assess differences in detection of csPC between cognitive and software-based TB stratified by TP-B indication. METHODS: Prospectively maintained TP-B databases across five institutions were retrospectively analyzed. All patients with PIRADS 3-5 lesions on MRI undergoing TB of the index lesion(s) were included. Baseline demographic and clinical data were captured. Primary outcome was detection of csPC (≥GG2) within a TB stratified by biopsy indication (BN, PNB, and AS) and whether cognitive or software-based fusion was used. Univariate and multivariate statistical analyses were performed. RESULTS: 1,546 TP-B (804 cognitive, 742 software) were included. Median age was 66 y, median PSA 6.9 ng/ml, and median prostate volume 48 cc. 758 were BN, 254 had PNB, and 510 were on AS. Overall csPC detection on TB was 40.9%. On multivariable analysis, there was no significant difference in detection of csPC between cognitive and software-based TB overall (OR 1.15, 95% CI 0.85-1.55, p=0.38). Stratified by biopsy indication, software-based targeting improved detection of csPC in the PNB population (OR 5.02, 95% CI 1.71-16.5, p<0.01). There was no significant difference for BN (OR 0.78, 95% CI 0.52-1.17, p=0.23) or AS (OR 1.59, 95% CI 0.92-2.79, p=0.10). CONCLUSIONS: In a large, multi-institutional cohort undergoing TB of suspicious MRI lesions, we found no significant difference overall in detection of csPC whether a cognitive or software-based technique was used. When stratified by biopsy indication, this lack of difference persisted for BN and AS patients; however, software-based fusion outperformed cognitive fusion in the PNB population.
