Of the EGFR Mutation is an inclusion criterion in 1 clinical trial trial that contains Epidermal growth factor receptor mutations in lung cancer. EGFR is altered in 1.16% of thyroid gland carcinoma patients Primary resistance to EGFR TKIs is mostly due to the presence of wild-type EGFR, since these tumors harbor mutations in other genes downstream of EGFR such as KRAS and BRAF that may play a role in predicting clinical response to anti-EGFR therapies. [4]. In the cell, TKIs compete with ATP to bind the catalytic domain of the kinase, which in turn inhibits EGFR autophosphorylation and downstream signaling, including cell proliferation and survival.
