Risk score derived from 3-gene signature is a prognostic biomarker for disease free survival (DFS). a, c, e KM survival, risk score and time-dependent ROC curves of DFS in TCGA-PRAD training cohort. b, d, f KM survival, risk score and time-dependent ROC curves of DFS in MSKCC validation cohort. The high-risk and low-risk groups were stratified at optimal cut-off due to the risk score. The AUC was assessed at 1, 3 and 5 years
