Validation of the NETs Risk Score Model and Nomogram. (A) Kaplan-Meier survival analysis in the GSE39582 validation cohort (log-rank p = 0.00025). (B) Kaplan-Meier survival analysis in the GSE17538 validation cohort (log-rank p = 0.0018). (C) ROC curves for 1-, 3-, and 5-year survival prediction in GSE39582 (AUC: 0.638, 0.586, 0.585). (D) ROC curves for 1-, 3-, and 5-year survival prediction in GSE17538 (AUC: 0.638, 0.593, 0.598). (E) Nomogram integrating NETs risk scores and clinicopathological features (age, TNM stage) to predict 5-year overall survival. (F) Calibration curve comparing predicted vs. observed 5-year OS probabilities (dashed line: ideal fit).
