The results demonstrated that galactose metabolism, nitrogen metabolism, ERBB signaling pathway and pathways in cancer were significantly enriched in the high-risk group (Figure 6A, 6B) and that arachidonic acid metabolism, fatty acid metabolism, linoleic acid metabolism, B cell receptor signaling pathway, T cell receptor signaling pathway, intestinal immune network for IgA production and cytokine_cytokine receptor interaction were significantly enriched in the low-risk group (Figure 6C, 6D). This evidence concerns the gene CD79A and cancer.
