The highly enriched pathways were MAPK signaling pathway, Rap1 signaling pathway, Ras signaling pathway, EGFR tyrosine kinase inhibitor resistance, ErbB signaling pathway, and so on, which were well-known signalings for tumor growths and metastasis, indicating the protumor immune microenvironment (Figures 2(d) and 2(f)). This evidence concerns the gene EGFR and neoplasm.
