Abstract:
We report the case of an 85-year-old man who was surgically diagnosed with lung adenocarcinoma (pT2aN1M0 stage IIA). He was administered platinum combination chemotherapy as first-line treatment for lung cancer recurrence. The patient's pleural fluid sample was obtained and analysed using a next-generation sequencer, which demonstrated the presence of mesenchymal-epithelial transition gene (MET) exon 14 skipping mutations. As the patient developed progressive disease after receiving first-line chemotherapy, crizotinib was administered as the second-line treatment. The treatment was effective, and the patient had a stable disease for 7 months. This case suggests that crizotinib is effective against non-small cell lung cancer with MET exon 14 alterations.
