CD274 and neoplasm: The difference in the rate of PD-L1-positivity between CD3-positive and CD3-negative cases is statistically significant (Fisher’s exact test p = 0.033), and there is a positive correlation between CD3-positive TILs count and the percentage of PD-L1-positive tumor cells within primary tumors (Spearman’s rank correlation rho 0.365, p = 0.005).
