CD274 and neoplasm: First, we found a correlation with the lymphocyte infiltrate (both peri-tumoral and intra-tumoral tumor-infiltrative lymphocytes, TILs), available for 44 samples and scored in four categories (none, small, moderate, or strong infiltrate): the percentage of “PDL1-high” samples increased with the degree of lymphocyte infiltrate (p = 0.001).
