CPS = Combined Positive Score, defined as the number of PD-L1 staining cells divided by the total number of viable cells, multiplied by 100; CPS ≥ 1% denoted PD-L1 positive expression ECOG PS = Eastern Cooperative Oncology Group Performance Status. N/A = Not applicable. Pt = patient. TIL infiltration = intensity of tumor-infiltrating lymphocytes within tumor nests on a scale of 0 to 3; 0 = absence of TIL, 1 = few amounts of TIL, 2 = moderate amounts of TIL, 3 = high amount of TIL. SCC = squamous cell carcinoma.
