For example, gefitinib, erlotinib, and afatinib are potent targeted agents that are used for the treatment of advanced non-small cell lung cancers in which the gene coding for the epidermal growth factor receptor (EGFR) has been mutated (Mitsudomi et al., 2010; Wu et al., 2017). This evidence concerns the gene EGFR and non-small cell lung carcinoma.
