Prognostic significance of epidermal growth factor receptor and programmed cell death-ligand 1 co-expression in esophageal squamous cell carcinoma
Figure 6. Survival analysis of EGFR and PD-L1 in ESCC and the nomogram. (A) ROC curves of EGFR gene predicting prognosis. EGFR expression isn’t associated with OS (B) and DFS (C) in TCGA-ESCC. (D) ROC curves of PD-L1 gene predicting prognosis. PD-L1 expression isn’t associated with OS (E) and DFS (F) in TCGA-ESCC. (G) Nomogram for predicting 1-, 3-, and 5-year OS of ESCC based on clinicopathological features and the expression of EGFR and PD-L1. (H) Calibration curves of prediction models for 1-year survival of nomograms. Abbreviations: ROC: receiver operating characteristic; EGFR: Epidermal Growth Factor Receptor; OS: Overall Survival; DFS: Disease Free Survival; TCGA: The Cancer Genome Atlas; ESCC: Esophageal Squamous Cell Carcinoma; PD-L1: Programmed Death-Ligand 1.
