Figure 7. Immunotherapy response analysis. (A) A heatmap was drawn to illustrate the relationship between immune cell expression and stromal score, immune score, estimate score, and tumor purity. Immune cell expressions were lower in the high-risk group. (B) The stromal score was lower in the high-risk group than in the low-risk group (P<0.001). (C) The immune score was lower in the high-risk group than in the low-risk group (P<0.001). (D) The ESTIMATE score was lower in the high-risk group than in the low-risk group (P<0.001). (E) Patients in the high-risk group had higher tumor purity scores than those in the low-risk group (P<0.001). (F–I) The low-risk subtype has significantly greater IPS.
