CD8A and neoplasm: CIBERSORT algorithm showed that the level of CD8 T cells in the high-GMII group was significantly lower than that in the low-GMII group (p < 0.05), and the level of immunosuppressive M2-type macrophages was increased in the high-GMII group, suggesting that the high-GMII group had higher immunosuppressive activity and promoted tumor progression (Figure 5E).
