External validation of the 5-gene signature in GSE dataset (combined GSE62452 and GSE28735). A Patients in GSE dataset were divided into high-risk score and low-risk score groups according to the risk scores calculated with 5-gene signature. B Kaplan–Meier analysis estimates the OS of high-risk and low-risk groups in validation dataset. C ROC curves for 3-year OS by the 5-gene signature in training and validation dataset
