Small-molecule inhibitors of the EGF receptor's tyrosine kinase domain (TKIs), including gefitinib and erlotinib, have been widely used for treating NSCLC.
Previous studies have shown a correlation between expression of the EGF receptor type III mutation (EGFRvIII) and a more malignant phenotype of various cancers including: non-small-cell lung cancer, glioblastoma multiforme, prostate cancer and breast cancer.
Accumulating evidence suggest that patients with advanced non-small-cell lung cancer (NSCLC) and specific genomic alterations including epidermal growth factor receptor and microtubule-associated protein-like 4 anaplastic lymphoma kinase could significantly benefit from molecular-targeted therapies compared with chemotherapy.
Additional studies in non-small-cell lung cancer have suggested that the k-ras mutation may be a negative predictor of response to the EGF receptor tyrosine kinase inhibitors erlotinib and gefitinib.
The development of small-molecule tyrosine kinase inhibitors (TKI) specific for epidermal growth factor receptors (EGFR) with activating mutations has led to a new paradigm in the treatment of non-small cell lung cancer (NSCLC) patients.
The identification of activating mutations in the tyrosine kinase domain of the EGF receptor (EGFR) predictive of response to tyrosine kinase inhibitors (TKIs) led to a therapeutic revolution in the treatment of patients with metastatic non-small-cell lung cancer (NSCLC).
To evaluate response rate, toxicity and epidermal growth factor (EGFR) mutations and gene copy number as outcome predictive factors in Italian patients with non-small cell lung cancer (NSCLC) treated with gefitinib (Iressa) in an expanded access program (EAP).
Choroidal metastasis from non-small-cell lung cancer responsive to Osimertinib: a case report : Efficacy of a third-generation epidermal growth factor tyrosine kinase inhibitor.
ABSTRACT The presence of EGFR mutations predicts the sensitivity to EGF receptor (EGFR)-tyrosine kinase inhibitors in a molecularly defined subset of non-small-cell lung carcinoma (NSCLC) patients.
To investigate the role of conventional radiotherapy (RT) and stereotactic body radiotherapy (SBRT) in patients with epidermal growth factor (EGFR)-mutant or anaplastic lymphoma kinase (ALK) rearrangement-positive metastatic non-small cell lung cancer (NSCLC).
<b>Introduction</b>: Cancer immunotherapy has revolutionized the treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC).However, specific patient groups (e.g. patients with activating <i>epidermal growth factor receptor</i> [<i>EGFR]</i> mutations) do not appear to derive benefit from immune checkpoint inhibitor (ICI) monotherapy.
This brief review is a snapshot of the complex problem of therapeutic resistance, with a focus on resistance to kinase inhibitors in EGF receptor mutant and ALK rearranged non-small cell lung cancer, BRAF-mutant melanoma, and BCR-ABL-positive chronic myeloid leukemia.
In Australia, mutations in epidermal growth factor mutations (EGFR) occur in 15% of patients diagnosed with non-small-cell lung cancer and are found with higher frequency in female, non-smokers of Asian ethnicity.
Although patients with the echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase gene (EML4-ALK) re-arrangement and epidermal growth factor gene EGFR mutations have proven sensitive to specific inhibitors, there is currently no consensus regarding the sensitivity of non-small cell lung cancer (NSCLC) patients with such mutations to cytotoxic chemotherapy.
Small molecule Tyrosine Kinase (TK) Inhibitors acting on the Epidermal Growth Factor Receptors (EGFRs) are standard therapies for patients with NSCLC harboring EGFR-TK inhibitor-sensitizing mutations.
Lung cancer is one of the leading cause of cancer death worldwide, the most common histological type of lung cancer is non-small cell lung cancer (NSCLC), whose occurrence and development is closely related to the mutation and amplification of epidermal growth factor receptors (EGFR).
When compared to the reference genotype (EGF +61A/A), we found a statistically significant association between EGF+61 A/G (OR = 2.142, 95 % CI 1.170-3.924) and EGF +61G/G (OR = 2.398, 95 % CI 1.157-4.968) genotypes and susceptibility to development of NSCLC.
We reported a case of non-small cell lung cancer harboring a rare epidermal growth factor somatic mutation, codon 768 AGC > ATC in exon 20 (S768I), who showed a good clinical response to gefitinib.
Mutations of the epidermal growth factor hormone receptor (EGFR) gene have been associated with improved treatment response and prognosis in advanced non-small lung cancer (NSCLC).
Tyrosine kinase inhibitors (TKIs) of the EGF receptor (EGFR) have provided a significant improvement in the disease outcome of nonsmall cell lung cancer (NSCLC).
