Then, we described the immune landscape of HCC based on tumor and stromal compartments and summarized four immune subtypes: Wound Healing (Immune C1), Inflammatory (Immune C3), TLymphocyte Depleted (Immune C4), and IFN-gamma Dominant (Immune C2), and found that the four immune subtypes had significant differences between DRGPI subgroups (p = 0.001) (Figure 7D). The gene discussed is IFNG; the disease is hepatocellular carcinoma.
