Programmed cell death ligand 1 (PD-L1) expression on gastric cancer and its relationship with clinicopathologic factors.

Abstract

The expression of PD-L1 was found in half of stages II and III gastric cancer patients. Positive of PD-L1 expression indicated poor survival in Chinese stages II and III gastric adenocarcinoma patients. These results may provide the clue for immunotherapy in the adjuvant treatment setting of gastric cancer patients.
