: The therapy of patients with lung adenocarcinoma has significantly changed after the discovery of epidermal growth factor receptor (EGFR) mutations. EGFR mutations occur in 10-15% of Caucasian lung cancer patients and are associated with favorable outcome to orally administered EGFR tyrosine kinase inhibitors (TKIs), like erlotinib. However, as soon as the tumor cells are under the pressure of the specific inhibitor, compensatory signaling pathways are activated and resistance emerges. : In this review we will focus on the mechanisms of resistance to the first-generation EGFR TKI, erlotinib, and will mainly summarize the findings throughout the last 10 years in the field of EGFR-mutant lung cancer. : Widespread research has been performed and several mechanisms of resistance to EGFR TKIs, especially first- and second-generation, have been identified. Still, no adequate combinatory therapies have received regulatory approval for the treatment of EGFR-mutant patients at the time of resistance. The third-generation EGFR TKI, osimertinibhas been approved for patients whose tumor has become resistant through the secondary T790M resistant EGFR mutation. The identification of the mechanisms of resistance and the application of the adequate therapy to each patient is still an unmet need.

Epidermal growth factor receptor (EGFR) gene alterations are associated with sensitization to tyrosine kinase inhibitors such as gefitinib in lung cancer. Some patients suffering from non-small cell l...
Patients with non-small cell lung cancer (NSCLC) treated with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) eventually develop resistance to these drugs. Although various m...
Gefitinib, a tyrosine kinase inhibitor of epidermal growth factor receptor, has been used as the first choice of treatment for advanced non-small-cell lung cancer. However, during the course of treatm...
Lung squamous cell carcinomas (SCC) typically harbor a strong activation of epidermal growth factor receptor (EGFR) pathway. Since one of the most common resistance mechanisms against EGFR inhibition ...
To review and assess the quality of the available evidence on the cost-effectiveness of erlotinib in the first-line treatment of advanced non-small cell lung cancer (NSCLC).
The purpose of this research study is to assess the frequency of the development of mutations (especially EGFR mutations) that lead to resistance to erlotinib in people with non-small cell...
This study will test whether treatment with erlotinib plus SU011248 is better than erlotinib alone in patients with advanced/metastatic lung cancer who have received previous treatment wit...
This is a phase 1 study. The goal of this study is to test the safety of combining the drugs erlotinib and ruxolitinib at different dose levels. The investigators want to find out what eff...
This is a randomized, placebo-controlled, double blind phase 2 study designed to compare treatment with ARQ 197 plus erlotinib to erlotinib plus placebo in patients with non-small cell lun...
A Safety and Efficacy Study of INC280 Alone, and in Combination With Erlotinib, Compared to Chemotherapy, in Advanced/Metastatic Non-small Cell Lung Cancer Patients With EGFR Mutation and cMET Amplification
The purpose of this study is to determine the maximum tolerated dose (MTD) or recommended phase II dose (RP2D) of INC280 in combination with erlotinib in the Phase Ib of this study, and to...
A quinazoline derivative and ANTINEOPLASTIC AGENT that functions as a PROTEIN KINASE INHIBITOR for EGFR associated tyrosine kinase. It is used in the treatment of NON-SMALL CELL LUNG CANCER.
Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.
A form of highly malignant lung cancer that is composed of small ovoid cells (SMALL CELL CARCINOMA).
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
A cell adhesion molecule that contains extracellular immunoglobulin V and C2 domains. It mediates homophilic and heterophilic cell-cell adhesion independently of calcium, and acts as a tumor suppressor in NON-SMALL-CELL LUNG CANCER (NSCLC) cells. Its interaction with NATURAL KILLER CELLS is important for their cytotoxicity and its expression by MAST CELLS plays a role in their interaction with neurons; it may also function in synapse assembly, nerve growth and differentiation.
GILOTRIF (afatinib) is a kinase inhibitor indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 (L8...
