Core Tip |
The clinical significance of expression of programmed death ligand-1 (PD-L1) in esophageal squamous cell carcinoma (ESCC) has not yet been fully established. We analyzed tissue microarrays of surgical specimen of 200 ESCC patients by immunohistochemistry with antibodies directed against PD-L1, p16, and c-Met. Our results suggest that tumors from approximately one-third of the ESCC patients are positive for PD-L1 expression, and PD-L1 expression is positively correlated with c-Met expression. Although PD-L1 positivity was not found to be associated with survival of ESCC patients, we show that it may play a critical role in distant failure and progression of ESCC.
