Pathological significance of abnormal recepteur d’origine nantais and programmed death ligand 1 expression in colorectal cancer

Figure 4 Kaplan-Meier analysis of overall survival of patients with colorectal cancer stratified by RON and/or PD-L1 expression. A: Overall survival (OS) according to RON expression in tumor cells (TCs); B: OS according to PD-L1 expression in TCs; C: OS according to PD-L1 expression in tumor-infiltrating mononuclear cells (TIMCs); D: OS according to RON and PD-L1 expression in TCs; E: OS according to RON expression in TCs and PD-L1 expression in TIMCs. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001.
