RESULTS PD-L1 expression was detected in both tumor cells and TILs at a ratio of 8.5 % and 25.1 % respectively. PD-L1 expression in TILs was related to histological grade and abundance of TILs. Tumor cell expression of PD-L1 was not associated with outcome. While PD-L1 expression in TILs and lymphnode transfer were associated with a poor outcome, and PD-L1 expression was an independently prognostic of overall survival (OS) (HR = 0.867, P = 0.029). CONCLUSION PD-L1 expression in TILs, but not in tumor cells, was a poor prognostic fa
