[Recommendations from Experts in the Management of Adverse Reactions 
to ALK Inhibitors (2021 Version)].

Anaplastic lymphoma kinase (ALK) fusion gene, as a tumor driver gene, was crucial for the occurrence and development of non-small cell lung cancer (NSCLC). Recently, targeted ALK fusion gene has become the main treatment method for ALK-positive NSCLC. The first and second generation ALK inhibitors (ALKi), such as crizotinib, ceritinib, alectinib and ensartinib have been approved in China. However, there was no guidance for the management of ALKi adverse reactions. Therefore, this "Recommendations from experts in the management of adverse reactions to ALK inhibitors (2021 version)" has been summarized, led by Lung Cancer Professional Committee of Sichuan Cancer Society and Sichuan Medical Quality Control Center for Tumor Diseases, to provide practical and feasible strategies for clinical ALKi management specification of adverse reactions. .
