MET mutation

MET amplification alters the balance of EGFR/MET/ERBB3 dimerization, leading to a shift in signaling dependence from EGFR to MET. These findings provide insight into therapeutic strategies for EGFR-mutated NSCLC.

Our findings support a monoclonal origin for ASC, with smoking influencing divergent evolutionary trajectories and immune microenvironment characteristics between ACC and SCCC. These insights provide a molecular framework for personalized ASC therapies.

EGFR tyrosine kinase inhibitors (TKIs) have transformed management, with first-line osimertinib demonstrating a median progression-free survival (PFS) of 18.9 months and overall survival (OS) of 38.6 months in the FLAURA trial...Understanding these mechanisms is critical for optimizing patient outcomes and guiding personalized therapeutic approaches. This review discusses current strategies to delay or overcome resistance and highlights emerging therapeutic avenues with the potential to reshape the management of EGFR-mutant NSCLC.

Here, we report a novel chemical series discovered through iterative core enumeration and decoration guided by free energy perturbation calculations. Type-III inhibitor 20 demonstrated potent activity against both WT and c-MET with the D1228V resistance mutation with promising physicochemical properties, laying the foundation for the development of brain-penetrant therapies targeting c-MET-driven cancers.

Patients with EGFR-mutant LUSC or LUAS had shorter overall survival on first-line osimertinib compared with those with EGFR-mutant LUAD...Combined EGFR and MET inhibition suppressed tumor growth in patient-derived xenograft models of LUSC transformation. Together, these findings highlight Rb pathway inactivation as a promoter of LUSC transformation in EGFR-mutant lung cancer and identify MET signaling as a therapeutic vulnerability that may suppress plasticity in this setting and extend response to targeted therapy.

The LiBRA study supports liquid biopsy as a prognostic and monitoring tool in BRAF V600E-mutated NSCLC undergoing targeted therapy.

We report a 59-year-old female non-smoker with stage IV EGFR Leu858Arg-mutated lung adenocarcinoma who sequentially received first-line osimertinib (~9 months), second-line osimertinib plus savolitinib for MET amplification (~20 months), third-line platinum-based chemotherapy with local ablative therapy for oligo-progression, and fourth-line docetaxel. This case illustrates that an acquired BRAF fusion may emerge as a potentially targetable bypass alteration in EGFR-mutated MET-amplified NSCLC after progression on combined EGFR-MET inhibition and that the combination of a first-generation EGFR-TKI and a MEK inhibitor can be associated with prolonged systemic disease control. The findings are hypothesis-generating and support the value of CGP at sequential progression points to guide mechanism-based therapy in oncogene-driven NSCLC.

This case underscores dynamic clonal evolution in advanced NSCLC: the initial L747S/L858R clone showed Osimertinib sensitivity, while subsequent resistance revealed a distinct profile (distinct TP53 mutation, MET amplification, high PD-L1/TMB) that explained the durable response to Pembrolizumab. These findings provide crucial evidence for sequential therapy strategies in compound EGFR mutations. Our findings also highlight the utility of Next Generation Sequencing (NGS) in identifying targetable resistance mechanisms, enabling prolonged survival in patients with compound EGFR mutations and offering valuable insights for clinical decision-making.
