Kaplan-Meier curves of disease-free survival (DFS) and overall survival (OS) in esophageal squamous cell carcinoma (ESCC) based upon PD-L1 expression in tumor cells. a Patients with PD-L1 expression had significantly shorter DFS than those without PD-L1 expression (median DFS time: 18 verse 41 months, P = 0.008). b There was no statistically significant difference in OS between the patients with positive and negative PD-L1 staining (median OS time: 36 verse 60 months, P = 0.140)
