Although there was no difference (p=0.11) between the two groups with high and low expression of IL2RG in relapse-free survival, the relapse-free survival of the group with higher expression of IL2RG was lower than the group with low expression of IL2RG (Figure 3(d)), while higher expression of IL2RG was closely related to poor overall survival in GC (p=1.1e − 15) (Figure 3(e)). The gene discussed is IL2RG; the disease is gastric cancer.
