PTPRF and posterior cortical atrophy: A set of five genes (PCBP1, PABPN1, PTPRF, DANCR, and MYC) was retained after applying LASSO (Lambda minimum = 0.009302712; Figures S3A, B) and multivariate Cox regression analyses to the training cohort and was considered as an optimal prognostic model for PFS of PCa patients (Table S9, Figure 4A).
