Abstract
Here, we report a case of lung adenocarcinoma resistant to crizotinib harboring KRAS mutation and the echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) fusion gene. Our case suggests that KRAS mutation in addition to EML4-ALK fusion gene may cause the resistance to crizotinib.
