ROCs curve for the nomograms. (A) The ROC curve of nomogram with 3-year OS in training set; (B) the ROC curve of nomogram with 5-year OS in training set; (C) the ROC curve of nomogram with 3-year OS in validation set; (D) the ROC curve of nomogram with 5-year OS in validation set; (E) the ROC curve of nomogram with 3-year CSS in training set; (F) the ROC curve of nomogram with 5-year CSS in training set; (G) the ROC curve of nomogram with 3-year CSS in validation set; (H) the ROC curve of nomogram with 5-year CSS in validation set. ROC, receiver operating characteristic; OS, overall survival; CSS, cancer-specific survival; AUC, area under ROC curve; FP, false positive; TP, true positive.
