Examples of these molecularly targeted biomarker therapies are: tyrosine kinase inhibitors in chronic myeloid leukemia and gastrointestinal tumors; anaplastic lymphoma kinase (ALK) inhibitors in lung cancer with EML4-ALk fusion; HER2/neu blockage in HER2/neu-positive breast cancer; and epidermal growth factor receptors (EGFR) inhibition in EGFR-mutated lung cancer.
The role of EGF receptor (EGFR) inhibitors in the treatment of lung cancer without activating EGFR mutations has been a controversial issue, particularly their relative efficacy over the available chemotherapy in the second- and third-line setting.
A test to predict outcome after treatment with an epidermal growth factor rector/tyrosine kinase inhibitor and a screening blood test for lung cancer are being investigated for use in proteomic profiling.
Although the majority of patients with EGFR-mutant lung cancer respond well to EGF receptor (EGFR) tyrosine kinase inhibitors (TKI), all patients eventually develop resistance.
We created a proof-of-principle database [DNA-mutation Inventory to Refine and Enhance Cancer Treatment (DIRECT)], starting with lung cancer-associated EGF receptor (EGFR) mutations, to provide a resource for clinicians to prioritize treatment decisions based on a patient's tumor mutations at the point of care.
Epidermal growth factor (EGF) receptor (EGFR) mutations are the best illustration of the therapeutic relevance of identifying such molecular clusters of lung cancer based on driver genetic alterations that predict the efficacy of specific tyrosine kinase inhibitors, a strategy referred to as "personalized medicine."
The interplay between EGFR and AURKA provides an explanation for the difference in EGF dependency between EGFR-WT and EGFR-mutant cells and may provide a new therapeutic strategy for lung cancer patients carrying EGFR mutations.
Results of multiple clinical trials suggest that EGF receptor (EGFR) tyrosine kinase inhibitors (TKI) exhibit negative effects on platinum-based chemotherapy in patients with lung cancer with wild-type (WT) EGFR, but the underlying molecular mechanisms are still uncertain.
Although the EGF receptor tyrosine kinase inhibitors (EGFR-TKI) erlotinib and gefitinib have shown dramatic effects against EGFR mutant lung cancer, patients become resistant by various mechanisms, including gatekeeper EGFR-T790M mutation, Met amplification, and HGF overexpression, thereafter relapsing.
Treatment strategies for non-small-cell lung cancer, the most common form of lung cancer, continue to evolve, most recently with the positive trial results for EGF receptor (EGFR) tyrosine kinase inhibitors in the first-line setting in molecularly targeted populations.
Collectively, our in vivo and in vitro findings support that TWIST1 collaborates with the EGF pathway in promoting EMT in EGFR mutated lung adenocarcinoma and that large series of EGFR mutated lung cancer patients are needed to further define the prognostic role of TWIST1 reactivation in this subgroup.
