Kaplan-Meier overall survival curves of PD1/PDL1 expression or CD8+T cells/CD68+M density in GC. GC patients with MSI, PD1 positive, and PDL1[T]/PDL1 negative had better prognosis (P=0.006, 0.012, 0.005 and 0.022, respectively). There are no correlations between CD8+T cells/CD68+M density and prognosis in GC (P=0.870 and 0.985, respectively).
