EBV-positive GC which is known to have high programmed death-ligand 1 (PD-L1) expression mainly has morphologic features of GC with lymphoid stroma, that is, so-called lymphoepithelioma-like GC, with similarities to nasopharyngeal carcinoma and different from the typical intestinal-type or diffuse-type GC [4]. This evidence concerns the gene CD274 and nasopharyngeal type undifferentiated carcinoma.
