The results of this analysis contains apoptosis, focal adhesion, neuroactive ligand–receptor interaction, the p53 signalling pathway, hepatitis B, EGFR tyrosine kinase inhibitor resistance, microRNAs in cancer, the TNF signalling pathway, endocrine resistance, mismatch repair and the PI3K-Akt signalling pathway (p<0.05). This evidence concerns the gene EGFR and cancer.
