Conclusions Crizotinib proved highly effective in pts with METmut aNSCLC, with a manageable toxicity profile. Additional research is warranted to identify biomarkers for response.
"CONCLUSION Activating MET TKD mutations without concurrent MET exon 14 mutations were detected in ~ 0.2% of NSCLC, and occur in the absence of other known drivers in a subset of cases. Comprehensive genomic profiling to detect these alterations and guide treatment selection and clinical trial enrollment is warranted."
MET TKD mutations were identified in both baseline and patients treated with TKIs. MET-H1094Y might play an oncogenic role in NSCLC and may confer acquired resistance to EGFR-TKIs. Preliminary data indicates that EGFR-mutated NSCLC patients who acquired MET-V1092I or MET-H1094Y may benefit from combinatorial therapy with EGFR-TKI and MET-TKI, providing insights into personalized medical treatment.
