Kaplan–Meier plots for lung cancer patients with adenocarcinoma histology in cohort 2 according to a the amount of CD3+ TILs, b PD1+ TILs, and c the PD-L1 H-score in brain metastatic tissue. Overall survival was measured from the date of surgery until either death due to any cause or the last follow-up date. The cutoff-points were arbitrarily set to the median value of each variable. The significance of differences in survival curves were compared using a log-rank test. Abbreviations: TIL, tumor-infiltrating lymphocyte; PD-1, programmed cell death-1; PD-L1, programmed cell death ligand-1
