FCGR2A and neoplasm: The results of GSEA revealed that antigen processing and presentation, B cell receptor signaling pathway, chemokine signaling pathway, FcγR mediated phagocytosis, graft vs. host disease, hematopoietic cell lineage, intestinal immune network for IgA production, natural killer cell mediated cytotoxicity, nucleotide binding oligomerization domain (NOD) like receptor signaling pathway, T cell receptor signaling pathway, and Toll like receptor signaling pathway were main pathways enriched by intersected genes related to tumor immunity (Figure 5).
