Particularly, serial MR scans are widely investigated using the PRECISE criteria. To assess the ability of PRECISE criteria to predict ISUP GG upgrading of men with ISUP GG1 on AS in a multi-institutional cohort. METHODS: Retrospective analysis of men from four centers (Cambridge, Düsseldorf, Dresden, Essen). After AS inclusion with mpMRI and MRI/TRUS fusion-guided biopsy, all men underwent serial mpMRI and MRI/TRUS fusion-guided biopsy subsequently. Patients with at least 2 MR scans and two biopsies (baseline and follow-up, the latter after the 2nd scan) were included. PRECISE recommendations evaluate the radiological change on serial imaging using a 1-to-5 scale in which PRECISE 1 or 2 indicates radiological regression, PRECISE 3 stability and PRECISE 4 or 5 imply progression. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) of MRI progress (PRECISE≥4) for ISUP GG upgrading were calculated and plotted using Cumulative incidence curves, including log-rank tests for equality of cumulative incidence curve. RESULTS: In total, 396 men were available for analysis. Median follow-up was 36 months. Histopathological progression occurred in n=73 men (18%). For PRECISE 1-2 (n=27, 7% of cases) no progression occurred. In PRECISE 3 (n=254, 69%) progression rate was 4% and in PRECISE 4-5 (n=87, 24%) 36%. Sensitivity, specificity, PPV and NPV for PRECISE≥4 was 74%, 88%, 57% and 94%. Accuracy was 85%. Cumulative incidence curves are given in the Figure 1. Log-Rank-test demonstrated statistical significance (p<0.001) for PRECISE 4-5. CONCLUSIONS: This multi-institutional study has validated that a dedicated MRI-based scoring system of serial MRI scans can reliably aid to predict histopathological progress of men on AS within a median follow-up timespan of 36 months. In particular, men with MR progression are significantly at risk of ISUP GG upgrading.
