Tumor‐associated macrophages were considered to support the growth and metastasis of GC and were positively related to its invasion depth and clinical stage.32 Besides, CD3+ and CD8+ T lymphocytes with high infiltration have a connection with favorable outcomes in GC, suggesting the significant role of host immunity mediated by T cells in restraining tumor progression.2, 33 Consistent with the function of CD3+ and CD8+ T lymphocytes, activated dendritic cells and T cells follicular helper were anti‐tumor components associated with stromal score in our analysis. Here, CD8A is linked to gastric cancer.
