However, in a real-life settings, negative biopsies are not uncommon. Due to the relatively recent introduction of MRI and the limited data available, there are no recommendations for the follow-up (FU) of pts with a PI-RADS 5 lesion and a subsequent negative biopsy. In this study, we aimed to present long-term outcomes of this specific population. METHODS: We reviewed data from 876 consecutive pts scheduled for prostate biopsy due to a clinical suspicion of PCa. All pts underwent an MRI before the biopsy, which included systematic and targeted biopsy in case of suspicious MRI lesions. We assessed the presence of overall PCa and csPCa (defined as a ISUP≥2). Subsequent management and long-term outcomes for pts with a PI-RADS 5 lesion and a negative biopsy are presented. The accuracy of possible predictors for diagnosis of csPCa during the FU were examined. RESULTS: Overall, 109 (12.5%) pts initially presented with PI-RADS 5 lesions on MRI. Among these, 32 (29.4%) pts had a negative biopsy result. The mean age was 67 years (SD 59.5-71.5), the median total PSA was 7.9 ng/mL (IQR 4.8-11.6), and the median prostate volume was 67 mL (IQR 40.0-95.0). After a median FU of 50.5 months (IQR 42.5-62.5), among the 32 pts with a negative biopsy, 13 (38%) experienced a decrease in PSA levels, 11 (34%) had stable PSA levels, and 9 (28%) had increased PSA levels. During the FU, 16 (50%) underwent an additional MRI, and 10 (31%) had a ≥PI-RADS 3 lesion. Thirteen (41%) pts underwent at least one more biopsy. Four pts were diagnosed with PCa, of which three had csPCa. All of them had a suspicious lesion on the additional MRI. While MRI had a sensitivity of 100% in this population, its Positive Predictive Value (PPV) was only 30%. Among pts with a PSA density >0.15 before the repeated biopsy, 3 pts out of 6 had csPCa. When considering a PSA density >0.20 as a threshold, 3 pts out of 5 had csPCa. Therefore, a PSA density >0.20 had 100% sensitivity, 93% specificity, 60% PPV, and 100% Negative Predictive Value (NPV) in this population. CONCLUSIONS: We presented one of the studies with the longest FU on pts with a PI-RADS 5 lesion and a negative biopsy. After more than four years of median FU, these pts have a relatively low risk of receiving a diagnosis of csPCa. Along with MRI, PSA density appears to be one of the most effective tools in predicting the risk of the disease. Further studies on larger populations are needed to confirm our findings.
