Primary Resistance to Combination Therapy with First- and Third-Generation EGFR Tyrosine Kinase Inhibitors of Lung Adenocarcinoma Harboring EGFR 19Del/T790M/in Trans-C797S Mutations with Co-Occurring CTNNB1 Alteration

摘要

Epidermal growth factor receptor (EGFR) in trans-C797S alteration has been considered as one of the mechanisms, which leads to the resistance to third-generation tyrosine kinase inhibitors (TKI). Several reports have suggested that combination therapy with first- and third-generation TKIs might be effective for acquired trans-C797S alteration.
