MET gene can be amplified in a variety of tumors such as lung cancer, breast cancer, ovarian cancer, thyroid cancer, gastric cancer, colorectal cancer, etc. It is an independent prognostic factor, and the prognosis of patients with MET gene amplification is poor. In NSCLC, MET gene amplification is closely related to poor prognosis and TKIs drug resistance.
MET gene amplification is one of the targets of XALKORI (Crizotinib). Tumors in patients with MET gene amplification can shrink significantly after treatment.
