Role of crizotinib in c-mesenchymal-epidermal transition-positive nonsmall cell lung cancer patients.

The increasing cases of NSCLC and improved understanding of its molecular biology has lead to identification of its varied driver mutations. cMET amplification has an important role as resistance mechanism for EGFR TKIs. Crizotinib is a drug which shows its anti-tumoral effect in cMET positive cases. Here we present a case series of three such patients who achieved were cMET amplified and showed partial response on Crizotinib.
