Mp49-04 Is Multiparametric Mri Always Needed in Biopsy-Naïve Patients With Abnormal Digital Rectal Examination? A Single-Institutional Experience Combining Clinical and Micro-Ultrasonography Based Factors to Optimize Prostate Cancer Detection

You have accessJournal of UrologyProstate Cancer: Detection to assess the predictors of csPCa in patients with abnormal DRE, to assess and compare the clinical benefit of both microUS plus prostate-specific antigen density (PSAd) and mpMRI plus PSAd in this sub-cohort of patients. RESULTS: Overall, 182 biopsy naïve men were included. MicroUSTBx plus SBx achieved comparable detection rate to MTBx plus SBx in diagnosis of ciPCa and csPCa (ciPCa: 9.3% 17/182 vs 10% 19/182 p=0.5; csPCa: 63% 114/ 182 vs 62% 113/ 182; p=0.6). MicroUSTBx outperformed MTBx (ciPCa: 5.5% 10/182 vs 6.0% 11/182, p=0.3; csPCa: 57% 103/182 vs 54% 99/182; p=0.07). Using microUSTBx plus SBx would have avoided 68/182 (37%) unnecessary MTBx, while missing only 2/116 (1.7%) csPCa. At multivariable logistic regression model Prostate Risk Identification Using Micro-Ultrasound ≥ 3, Prostate Imaging Report and Data System≥4 and PSAd≥0.15 ng/ml2 emerged as independent predictors of csPCa (odds ratio: 4.28 95% CI 1.39-13.2; p=0.01; 3.05 95% CI 1.81-5.14; p<0.001; and 2.72 95% CI 1.32-5.59; p=0.006; respectively). The decision curve analysis of suspicious microUS plus PSAd≥0.15 ng/ml2 showed higher net benefit in the ability to identify true positives and reduce the number of unnecessary prostate biopsy in this subcategory of patients. CONCLUSIONS: The combination of microUSTBx and SBx showed equal diagnostic performance to an mpMRI-based approach in biopsy-naïve patients with an abnormal DRE. The combination of this approach with PSAd maximize the diagnostic accuracy while lowering the need for unnecessary biopsies.
