However, there are still some patients with primary resistance to TKI. And most patients who initially respond to treatment eventually develop resistance to these drugs, which the main molecular mechanisms are T790M and MET amplification. The new targeted therapies and combination drugs to overcome drug resistance is the subject of clinical research.
