Durable Response to Chemoimmunotherapy of a Lung Adenocarcinoma Harboring a MET Exon 14 Skipping Mutation

Chemoimmunotherapy is the first-line standard treatment for patients with non-small cell lung cancer (NSCLC). However, there are few reports on the efficacy of chemoimmunotherapy in patients with NSCLC who harbor the MET exon 14 skipping mutation. We report the case of an 81-year-old male patient with lung adenocarcinoma with a MET exon 14 skipping mutation who was treated with chemoimmunotherapy and achieved a durable response. Chemoimmunotherapy may be a promising treatment option for patients with a MET exon 14 skipping mutation. However, further studies are needed to characterize the objective response rate and response duration in these populations.
