These reports are predominantly from large academic centers with significant expertise. However, the added value of MR targeted biopsy for biopsy-naive patients in the community setting is largely unknown. METHODS: The Michigan Urological Surgery Improvement Collaborative (MUSIC) registry maintains a prospective MR and fusion biopsy database with technical, patient, provider, and lesion level data. All patients undergoing targeted and systematic biopsy in the same setting with no prior biopsy from August 2017 - May 2019 were included. Software-based MR/US fusion was used in all cases. Primary outcomes were the proportion of patients upgraded to ≥GG2 prostate cancer (PCa) by target and the proportion upgraded to ≥GG2 PCa based on systematic biopsy. RESULTS: Of 2375 fusion biopsies in the registry, 437 patients from 22 practices met inclusion criteria. Median age and pre-diagnosis PSA for the cohort was 66 years and 6.3 ng/ml, respectively. Overall cancer detection rate was 76.4% and the rate of clinically significant prostate cancer (csPCa) detection was 51.9%. Of the 227 cases of csPCa, 16% were detected by standard biopsy only, 17% by targeted biopsy only, and 67% by both techniques. Of all patients, 39 (8.9%) were upgraded to csPCa by targeted biopsy while 36 (8.2%) were upgraded to csPCa by standard biopsy. On bivariate analysis, we did not identify significant factors predictive of upgrading to csPCa by either technique. CONCLUSIONS: In biopsy-naïve patients, targeted biopsy upgrades approximately 1 in 10 patients to ≥GG2 prostate cancer. A similar proportion of patients with negative targeted biopsies were upgraded by systematic biopsy alone. There were no clinical variables associated with upgrading to ≥GG2 PCa by either biopsy method. Our findings suggest there is value in the community setting to adding mpMRI with targeted biopsy to the initial evaluation of biopsy-naive patients.
