Time-dependent ROC curves. a Time-dependent ROC curves of the OS nomogram showed that the AUCs in the training cohort were 0.842, 0.841, and 0.823 for predicting 3-, 5-, and 8-year OS, respectively; b Time-dependent ROC curves of the CSS nomogram in the training cohort showed that the AUCs were 0.889, 0.884, and 0.859 for predicting 3-, 5-, and 8-year CSS, respectively; c Time-dependent ROC curves of the OS nomogram showed that the AUCs in the validation cohort were 0.862, 0.839, and 0.825 for predicting 3-, 5-, and 8-year OS, respectively; d Time-dependent ROC curves of the CSS nomogram in the validation cohort showed that the AUCs were 0.878, 0.877, and 0.889 for predicting at 3-, 5-, and 8-year CSS, respectively. ROC: receiver operating characteristic; AUC: area under the curve; OS: overall survival; CSS: cancer-specific survival
