The variable responses to anti-HER2 therapies in these patients prompt us to examine impact of <i>HER2</i> variants and co-mutations on responses to anti-HER2 treatments in lung cancer.
Patients with lung cancer and HER2 mutations developed more brain metastases on treatment than patients with KRAS mutations (28% vs 8%; hazard ratio [HR], 5.2; P < .001) and trended more than patients with EGFR mutations (28% vs 16%; HR, 1.7; P = .06).
Activity of the EGFR-HER2 dual inhibitor afatinib in EGFR-mutant lung cancer patients with acquired resistance to reversible EGFR tyrosine kinase inhibitors.
We examined changes in CTC numbers and morphology early after targeting therapy in EGFR-mutated PC-9 human lung cancer and HER2-gene amplified GLM-1 gastric cancer mouse CTC models using a cytology-based semi-automated CTC detection platform.
Our results suggest that the polymorphisms of the HER-2 gene are associated with an increased susceptibility to lung cancer in females, non-smokers and non-drinkers subgroups in the Korean population.
We present a patient with HER2 mutant lung cancer with a 12 base pair insertion YVMA (p.A775_G776insYVMA), who had a long natural history and durable partial response to afatinib.
EGFR and HER2 mutations and ALK rearrangement are known to be related to lung cancer in never-smokers, while KRAS, BRAF and PIK3CA mutations are typically observed among smokers.
Dacomitinib (PF-00299804) is a small-molecule inhibitor of the tyrosine kinases human epidermal growth factor receptor-1 (HER1; epidermal growth factor receptor, EGFR), HER2, and HER4 currently being developed for the treatment of lung cancer with sensitizing mutations in EGFR or refractory to EGFR-directed treatment.
In contrast, afatinib and neratinib were predicted to be more effective than other inhibitors for the A775_776insYVMA mutation, the most frequent <i>ERBB2</i> mutation in lung cancer.
Herein, the authors describe the prevalence, clinical features, and outcomes associated with HER2 mutations in 1007 patients in the Lung Cancer Mutation Consortium (LCMC).
The excellent pharmacokinetic profiles of 19a in mice and rats led us to further investigation of a novel therapeutic agent for HER-2-targeting treatment of solid tumors, especially HER-2-positive breast/gastric cancer and HER-2-mutated lung cancer.
Combination of In Silico Analysis and In Vitro Assay to Investigate Drug Response to Human Epidermal Growth Factor Receptor 2 Mutations in Lung Cancer.
Germline mutations in EGFR and erb-b2 receptor tyrosine kinase 2 (ERBB2) have been previously reported in lung cancers that may be associated with genetic susceptibility to lung cancer.
