CD274 and neoplasm: The presence of remote metastases correlated with a higher immune cell score (IC, percentage of area of PD-L1-positive immune cells from area of vital tumor cells) (p = 0.014, r = 0.484), while poorer tumor differentiation (corresponding to higher grading/G-value) correlated with a lower CPS value (p = 0.037, r = -0.419).
