Figure 1. PD-L1 expression on tumor cells (TC) and tumor infiltrating immune cells (IC) in Chinese NSCLC patients.

Figure 1

(A) representative images on adenocarcinomas (a & b) and squamous carcinomas (c &d) showed PD-L1 negative staining (a), positive staining on TC (b), IC (c) and both on TC and IC (d) respectively by IHC. The arrows indicate PD-L1 positivity on TC, the triangle indicates PD-L1 positivity on IC; (B) Correlation between PD-L1 expression on TC and PD-L1 positivity in IC in 182 patients. Median (solid red lines) and the 1st and 3rd quantile (dashed red lines) are reported.
