Comparisons of the performances of survival predictions made by the 7-lncRNA signature, TNM stage and combined model of the signature and TNM stage. The performances of survival predictions made by the three methods were compared using receiver operating characteristic (ROC) analysis. a ROC curves of the 7-lncRNA signature, TNM stage and combined model for overall survival (OS) prediction in the training cohort. b ROC curves of the three methods for disease-free survival (DFS) prediction in the training cohort. c ROC curves of the three methods for OS prediction in the independent cohort. d ROC curves of the three methods for DFS prediction in the independent cohort
