BCR and posterior cortical atrophy: Therefore, EAU proposed a new BCR model after RP, which stratified patients into low- and high-risk classes with the former having a PSA doubling time longer than 1 year and/or pathology Gleason score <8; the model was validated externally and reached independent predictor status not only for metastatic progression but also for PCa-specific mortality; however, the discriminative ability of the model was moderate [7].
