Figure 9. Immunotherapy prediction of PRGs-based prognostic model for LSCC. (A) Immune checkpoint inhibitors related genes (PD1, CTLA4, LAG3, PD-L1, and HAVCR2) expression between high- and low-risk patients. (B) Differences in immunophenoscores between patients in high- and low-risk groups received anti-PD1 alone, anti-CTLA4 alone, and combination therapy with anti-CTLA4 and anti-PD1.
