BACKGROUND: Programmed cell death ligand 1 (PD-L1) expressed on tumor and immune cells are both associated with the response to programmed cell death 1 (PD-1) pathway blockade therapy. Here, we examine the role of CD8+PD-L1+ tumor-infiltrating lymphocyte (Tils) in the tumor microenvironment of non-small cell lung cancer (NSCLC). METHODS: Tumor tissue samples of a total of 378 patients from two NSCLC cohorts were...
