EGFR and neoplasm: In the gene enrichment analysis of the combined group, we found an enrichment of immune-related pathways, including the JAK/STAT signalling pathway, NOD-like receptor signalling pathway, T-cell receptor signalling pathway, TGF-beta signalling pathway, cytokine‒cytokine receptor interaction, and Toll-like receptor signalling pathway, as well as tumour-related pathways, including the CAM, Notch, MAPK, and ErbB signalling pathways (Supplementary Fig. 5a, b).
