EGFR and lung carcinoma: In lung cancer, the most frequent oncogene mutation occurs on the epidermal growth factor receptor (EGFR) gene, which results in overexpression in up to 80% of NSCLC cases, with Ki‐ras2 Kirsten rat sarcoma viral oncogene homologue (Kras) being the most common oncogene‐driven subtype of LUAD [38, 42].
