CD274 and neoplasm: An association between PD-L1 expression on tumor cells and LAG-3+ TIL infiltration was observed, as 8/43 (18.6%) samples with membranous PD-L1 expression on tumor cells were infiltrated by LAG-3+ lymphocytes in contrast to only 2/54 (3.7%) in PD-L1− cases (p = 0.021, Fisher’s exact test).
