COVID-19 is an emerging, rapidly evolving situation. Abstract. 2007 Nov 1;67(21):10417-27. doi: 10.1158/0008-5472.CAN-07-1248. -, Oxnard GR, Nguyen KS, Costa DB. This study was prospectively designed to evaluate a phase II study of gefitinib for non-small-cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations… Growth factor receptor as targets for antitumor therapy with monoclonal antibodies. However, current single agent receptor targeting does not achieve a maximal therapeutic effect, and some mutations confer resistance to current available agents. from cancer (almost 20 percent [%] of cancer deaths); NSCLC accounts for 80% to 85% of lung. Yu Z, Boggon TJ, Kobayashi S, Jin C, Ma PC, Dowlati A, Kern JA, Tenen DG, Halmos B. There were no significant differences in epidermal growth factor receptor or KRAS mutations by gender or primary versus metastatic lung cancer. 2008;452:638–642. The efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in non-small cell lung cancer (NSCLC) has been linked to activating mutations in the EGFR gene.

Multiple randomized clinical trials have demonstrated that epidermal growth factor receptor (EGFR) exon 19 deletion (19Del) and exon 21 L858R mutation (L858R) are highly correlated with sensitivity to epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment in non-small-cell lung cancer (NSCLC). The latter inhibit these kinases and their downstream effectors, and induce apoptosis in preclinical models. 2009 Aug;28 Suppl 1:S14-23. In 2004, several investigators reported that somatic mutations in the epidermal growth factor receptor gene were associated with clinical responses to erlotinib and gefitinib in patients with non–small cell lung cancer. 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. Responses were most pronounced in female non‐smokers with adenocarcinoma histology. Acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors in non-small-cell lung cancers dependent on the epidermal growth factor receptor pathway. Personalized medicine using targeted therapies has revolutionized the management of non-small cell lung cancer (NSCLC) in the past decade. N Engl J Med.

Ann Transl Med. In response to exposure to tobacco smoke, this epithelium becomes initially hyperplastic, then metaplastic, and then frankly dysplastic. Original Article from The New England Journal of Medicine — Screening for Epidermal Growth Factor Receptor Mutations in Lung Cancer 1988;45:147-160. In the normal lung, EGFR expression is limited to the basal layer of the epithelium, where proliferation occurs. Epidermal growth factor receptor (EGFR) mutations play an important role in the pathogenesis of nonsmall cell lung cancer (NSCLC) and are one of the main driver genes of NSCLC. Several driver mutations have been identified in lung cancer, such as epidermal growth factor receptor (EGFR) and K-ras mutations and anaplastic lymphoma kinase (ALK) rearrangement. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Minnelli C, Laudadio E, Mobbili G, Galeazzi R. Int J Mol Sci. Background. 2020 Mar;146(3):767-775. doi: 10.1007/s00432-019-03103-x. Lung adenocarcinomas with mutated epidermal growth factor receptor have significant responses to tyrosine kinase inhibitors, although for unselected patients it does not appear to have a survival benefit. J Natl Cancer Inst. Cancer Biol Med. In lung cancer, the molecules gefitinib and erlotinib which target the intracellular kinase domain of the epidermal growth factor receptor (EGFR), cause significant tumour responses and, in the case of erlotinib, a survival benefit in patients with previously treated cancers. The structure of the EGFR gene is shown at left, and the locations and types of the mutations in the tyrosine kinase (TK) domain are shown at right. Epidermal Growth Factor Receptor Mutations in the Blood of Patients With Advanced Non-Small Cell Lung Cancer. The aforementioned EGFR mutations are stout predictors of response and augmentation of progression-free survival when gefitinib, erlotinib, and afatinib are used for patients with advanced NSCLC. 2011 Jun;14(3):177-90. doi: 10.1016/j.drup.2011.02.004. Background: Many patients with non–small-cell lung cancer (NSCLC) who achieve radiographic responses to treatment with the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors gefitinib and erlotinib have somatic mutations in the EGFR tyrosine kinase domain. Clin Lung Cancer. We review the results of genetic, biochemical and clinical studies focused on somatic mutations of EGFR that are associated with the phenomenon of oncogene addiction, describing 'oncogenic shock' as a mechanistic explanation for the apoptosis that follows the acute treatment of susceptible cells with kinase inhibitors. Prog Allergy. However, the role of such mutations in the pathogenesis of lung … Identifying relationships between imaging phenotypes and lung cancer-related mutation status: EGFR and KRAS. This site needs JavaScript to work properly. The epidermal growth factor receptor (EGFR) has emerged as an attractive therapeutic target for patients with non–small-cell lung cancer (NSCLC). Cancer statistics, 2014. We performed this retrospective study to assess the association of epidermal growth factor receptor (EGFR) with metastatic presentations in advanced non-small cell lung cancer (NSCLC). Targeted therapy for these lung cancers has been established based on evidence regarding mainly common mutations; that is, exon 19 deletions (Del19) and L858R. Clin Cancer Res 2006; 12:6494. 2020 Oct;12(10):5505-5516. doi: 10.21037/jtd-19-3570. The amount of EGFR … Mutations within the epidermal growth factor receptor (EGFR/erbB1/Her1) are often associated with tumorigenesis. Predictive models for patients with lung carcinomas to identify EGFR mutation status via an artificial neural network based on multiple clinical information. Differentiating synchronous double primary lung adenocarcinomas from intrapulmonary metastasis by CT features, EGFR mutations and ALK rearrangement status. 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. 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). Method: The related database was systematically searched with keywords until … 2009 Jul;10(4):281-9. doi: 10.3816/CLC.2009.n.039. Background Most patients with non–small-cell lung cancer have no response to the tyrosine kinase inhibitor gefitinib, which targets the epidermal growth factor receptor (EGFR). Mutation in epidermal growth factor receptor (EGFR) gene is one of the principal mechanisms leading to tumorigenesis of non‐small‐cell lung cancer (NSCLC), and was found in up to 50% of Asian, female patients who never smoked. 2012 Jun ; 14 ( 3 ):177-90. doi: 10.3390/ijms21239323, a!, Bell DW, Sordella R, Daimiel I, Tsurutani J, Zou Z, a...
