Abstract:
Lung cancer is the most common cancer in China and even in the world, and it is also the main cause of cancer death. Patients with anaplastic lymphoma kinase (ALK) gene alterations have the opportunity to receive molecularly targeted therapies. The inhibitors of anaplastic lymphoma kinase, such as ALK-tyrosine kinase inhibitors (ALK-TKIs) significantly prolong the survival of patients. ALK gene variant types include point mutation, amplification, fusion/rearrangement, and ALK fusion is more common than other types. However, the effect of different types of gene changes in molecular targeted therapy is different. Therefore, this paper introduced the relevant contents of different variants of ALK gene, focused on the research progress of targeted therapy, and proposed the future development direction. .
