The expression of immune checkpoint molecules including PD-1, PD-L1, LAG3 and CTLA4. (A) Heatmap of immune checkpoint molecules expression, (B) Box plots showing the checkpoint molecules expression between the high risk and low risk group in the TCGA cohort. (C) Heatmap of immune checkpoint molecules expression, (D) Box plots showing the checkpoint molecules expression between the high risk and low risk group in the GSE13507 cohort. P values were showed as: ns, not significant; **,P < 0.01; ***, P < 0.001.
