Somatic mutations in the kinase domain of the epidermal growth factor receptor (EGFR) gene are detected in approximately 40% and 17% of lung adenocarcinoma in Asians 1 and in Caucasians, 2 respectively.

Epub 2013 Jun 12. Out of 76 sequenced lung cancer samples, 36.1% of EGFR mutations were missense along exon 19, 50.0% were missense along exon 21, 5.6% along exon 20 and 8.3% along exon 18 (Fig. Islas-Vazquez L, Aguilar-Cazares D, Galicia-Velasco M, Rumbo-Nava U, Meneses-Flores M, Luna-Rivero C, Lopez-Gonzalez JS. Lung cancer caused by EGFR mutations is often treated with a group of chemotherapy drugs called EGFR tyrosine kinase inhibitors (TKIs). This review provides an overview of the biology and incidence of uncommon EGFR mutations and summarizes reported outcomes when treated with EGFR-TKIs. NIH Cohen V, Agulnik JS, Ang C, Kasymjanova G, Batist G, Small D, Brandao G, Chong G, Miller WH Jr. Cancer. Ann Transl Med. For patients with NSCLC harboring EGFR-activating mutations, the use of EGFR tyrosine kinase inhibitors (EGFR TKIs), especially osimertinib, had the best recommendation as to first-line treatment. Activated p53 triggers cell fate decisions, such as senescence or apoptosis. This study was designed to evaluate the relationship between the mutational of the epidermal growth factor receptor (EGFR) and overall survival (OS) in NSCLC patients with brain metastases. While EGFR mutations appear more frequently in patients with certain clinical characteristics, no characteristics have been identified that are sufficient or necessary for such mutations to occur. 2005 Oct 1;11(19 Pt 1):6816-22. doi: 10.1158/1078-0432.CCR-05-0441.  |  10, 2015, Next-generation sequencing has allowed identification of millions of somatic mutations and epigenetic changes in cancer cells.

Preclinical rationale for PI3K/Akt/mTOR pathway inhibitors as therapy for epidermal growth factor receptor inhibitor-resistant non-small-cell lung cancer. Figure 3: The transmission and pathogenesis of ebolavirus infection. Aims Activating mutations in the gene encoding epidermal growth factor receptor (EGFR) can confer sensitivity to EGFR tyrosine kinase inhibitors such as gefitinib in patients with advanced non-small-cell lung cancer. In particular, EGFR mutations may be more common in the macropapillary subset of lung adenocarcinomas, a particularly aggressive lung cancer type [44, 53, 54]. Abstract: Lung cancer is the leading cause of cancer death worldwide. Research suggests that TP53 mutations combined with EGFR, ALK, or ROS1 gene mutations is linked with a shorter survival time. 2013 Dec;39(8):839-50. doi: 10.1016/j.ctrv.2013.05.001. 2020 Sep 18;12:8653-8662. doi: 10.2147/CMAR.S255967. 2013 Jul;14(4):322-32. doi: 10.1016/j.cllc.2012.12.001. ... We review the role of EGFR mutations in the diagnosis and management of NSCLC. Results: Uncommon EGFR mutations were observed in 218 patients, comprising 11.9% of all patients Nearly all these EGFR gene mutations occur during a person's lifetime (somatic) and are present only in cancer cells. 6, 2011, Epidermal growth factor receptor (EGFR) is a transmembrane protein with cytoplasmic kinase activity that transduces important growth factor signaling from the extracellular milieu to the cell. Epidermal growth factor receptor (EGFR) mutations are the second most common oncogenic driver event in non-small cell lung cancer (NSCLC). Most of lung cancers develop sporadically and thus inherited lung cancers are rare. NLM Background/aim: To describe real clinical outcomes in patients with non-small cell lung cancer who have uncommon epidermal growth factor receptor (EGFR) mutations. Clin Lung Cancer. 2006 Jul 15;12(14 Pt 2):4416s-4420s. Testing for mutations in EGFR is therefore an important step in the treatment-decision pathway. Driver mutations, such as those in the EGFR, have been shown to be significantly more often truncal events compared with mutations in non-driver genes that are usually branch mutations.26 As a consequence, the heterogeneous distribution of EGFR mutations in lung adenocarcinomas is extremely rare, as demonstrated in a seminal study of Yatabe et al.15 Of note, similar results were … Effect of epidermal growth factor receptor tyrosine kinase domain mutations on the outcome of patients with non-small cell lung cancer treated with epidermal growth factor receptor tyrosine kinase inhibitors. The epidermal growth factor receptor (EGFR) family members seem to play a critical role in lung tumourigenesis and are overexpressed in 40-80% of non-small cell lung carcinoma (NSCLC) tumours. non–small cell lung carcinoma, epidermal growth factor, receptor tyrosine kinase, tyrosine kinase inhibitor, sensitizing mutation, oncogene addiction, Laura Baseler, Daniel S. Chertow, Karl M. Johnson, Heinz Feldmann, David M. MorensVol. Given that more than 60% of non-small cell lung carcinomas (NSCLCs) express EGFR, EGFR has become an important therapeutic target for the treatment of these tumors. In this article, we review the four commonly known oncogenic driver mutations in lung cancer – EGFR mutations at exons 18 – 21, KRAS gene mutation at codons 12 and 13, EML4-ALK fusion genes and deregulation of METsignaling. Given that more than 60% of non-small cell lung carcinomas (NSCLCs) express EGFR, EGFR has become an important therapeutic target for the treatment of these tumors. Inhibitors that target the kinase domain of EGFR have been developed and are clinically active. 2A).These mutations were in and around the tyrosine kinase domain of EGFR (Fig. A key challenge in interpreting cancer genomes and epigenomes is distinguishing which genetic and epigenetic changes are drivers ...Read More, Gilda da Cunha Santos, Frances A. Shepherd, Ming Sound TsaoVol. Figure 2: Human fibroblasts, either presenescent (PRE) or senescent (SEN), were immunostained for the inflammatory cytokines interleukin (IL)-6 and IL-8, as well as the senescence marker p16. Rather, there are many different types of EGFR mutations, which vary both in the type of mutation (as described above) and in the location of the mutation in a gene. We review the role of EGFR mutations in the diagnosis and management of NSCLC. Materials andmethods: A total of 5363 lung cancer patients were screened and underwent EGFR genotyping at the Guangdong Lung Cancer Institute.

Although many rare EGFR mutations are associated with poorer responses to first-generation EGFRi compared to classical EGFR mutations, more effective alternative EGFRi have been identified for several rare EGFR mutations … Rare mutations in EGFR account for ˜15% of EGFR mutations in NSCLC, amounting to around 30,000 diagnoses per year owing to the high prevalence of lung cancer.
