Recently it has been reported that mutations in the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) gene occur in a subset of patients with lung cancer showing a dramatic response to EGFR tyrosine kinase inhibitors. Epub 2020 Dec 15. The discovery that sensitizing epidermal growth factor receptor (EGFR) mutations are predictive for therapeutic benefit from EGFR tyrosine kinase inhibitors (TKIs) such as erlotinib marked the beginning of a new era in lung cancer therapeutics. COVID-19 is an emerging, rapidly evolving situation. Jorge, S.S. Kobayashi and D.B. Lancet Oncol.

Activating mutations in the epidermal growth factor receptor underlying responsiveness of non-small cell lung cancer to gefitinib. Epidermal growth factor receptor (EGFR) mutations are the second most common oncogenic driver event in non-small cell lung cancer (NSCLC). Patients with advanced EGFR-mutant NSCLC have a variety of EGFR-targeting agents available proven to treat … Lung cancer; Mutations; Epidermal growth factor receptor (EGFR), a transmembrane glycoprotein, is related to the proliferation and resistance to apoptosis of cells. PURPOSE: The vast majority of epidermal growth factor receptor (EGFR) mutations occur in lung adenocarcinoma, and even rare cases of other subtypes with this mutation, such as adenosquamous cell carcinoma, are associated with adenocarcinoma histology. Lung cancers with EGFR gene mutations tend to respond to treatments that specifically target the overactive epidermal growth factor receptor protein that allows cancer cells to constantly grow and divide. doi: 10.3322/caac.21208. (A) Results from patients harboring the EGFR resistance mutation T790M (9 patients) are shown.

Non-small-cell lung cancer (NSCLC), the most prevalent subtype of this recalcitrant cancer, is usually diagnosed at advanced stages, and available systemic therapies are mostly palliative. doi: 10.1038/nature06846. Ongoing preclinical efforts for treating resistance have started to translate into patient care (including clinical trials of the covalent EGFR-T790M TKIs AZD9291 and CO-1686) and hold promise to further boost the median survival of patients with EGFR mutated NSCLC. This study assesses different technologies for detecting epidermal growth factor receptor (EGFR) mutations from circulating tumor DNA in patients with EGFR T790M‐positive advanced non–small cell lung cancer (NSCLC) from the AURA3 study (NCT02151981), and it evaluates clinical responses to osimertinib and platinum‐pemetrexed according to the plasma T790M status. Each codon of representative mutations was mapped on the protein sequence of the EGFR kinase domain. This is a unique report of receptor tyrosine kinase (RTK) “superacceptor” activity in which mutated EGFRs associated with lung cancer preferentially adopt the “acceptor” or “receiver” position in the presence of WT epidermal growth factor receptor (EGFR) or ErbB-2.

Purpose: In this phase I study (BLOOM), osimertinib, a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), was evaluated in patients with leptomeningeal metastases (LMs) from EGFR-mutated (EGFRm) advanced non-small-cell lung cancer (NSCLC) whose disease had progressed on previous EGFR-TKI therapy. Epidermal growth factor receptor ( EGFR ) gene mutations (G719X, exon 19 deletions/insertions, L858R, and L861Q) predict favorable responses to EGFR tyrosine kinase inhibitors (TKIs) in advanced non–small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) gene mutations are important for the pathogenesis of lung adenocarcinoma, and the tyrosine kinase function of EGFR is a promising target for the treatment of non-small cell lung cancer.In patients with advanced lung adenocarcinoma, those harboring EGFR mutations have longer survival than those without EGFR mutations, mainly due to the … N Engl J Med. 2014.
