Fig. 1From: Prognostic value of PD-L1 expression on tumor cells combined with CD8+ TIL density in patients with locally advanced non-small cell lung cancer treated with concurrent chemoradiotherapyPD-L1 expression on tumor cells and CD8 expression on tumor infiltrating lymphocytes. Representative images under a microscope with a 10x enlargement of adenocarcinomas with positive (a, 80%) and negative (b, 0%) PD-L1 staining on tumor cells and adenocarcinomas with positive (c, 70%) and negative (d, 2%) CD8 staining on tumor infiltrating lymphocytes. The arrows indicate positive (a,c) or negative (b,d) stainingBack to article page
