An 84-year-old man was diagnosed with non-small cell lung cancer (cT3N2M1c stage IVB)...the patient was found to be positive for the MET exon 14 skipping mutation with ArcherMET...treatment with tepotinib (500 mg/day) was started. After the start of tepotinib administration, his PS improved to 0-1 after 1 week, and the partial response was maintained for more than 12 months (Fig. 1E, F). No serious side effects other than mild lower leg edema were observed....This report shows that targeted treatment of the MET exon 14 skipping mutation may be beneficial, even for elderly patients with poor PS.
