In recent years, with the development of molecular typing technology, people have a new understanding of the biological mechanism of the occurrence and development of NSCLC, found several special subtypes of driving genes such as epidermal growth factor receptor (EGFR), adenolymphoma kinase (ALK), threonine protein kinase, and developed corresponding targeted drugs, opening the era of accurate treatment of NSCLC [6]. Here, ALK is linked to non-small cell lung carcinoma.
