[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. .【中文题目：间变性淋巴瘤激酶抑制剂不良反应管理 西南专家建议（2021年版）】 【中文摘要：间变性淋巴瘤激酶（anaplastic lymphoma kinase, ALK）融合基因作为肿瘤驱动基因，对非小细胞肺癌（non-small cell lung cancer, NSCLC）的发生和发展至关重要，而靶向ALK融合基因已成为ALK阳性NSCLC患者的主要治疗手段。第一、二代ALK抑制剂（ALK inhibitor, ALKi）克唑替尼、塞瑞替尼、阿来替尼、恩沙替尼已在中国上市并广泛应用。然而，针对ALKi不良反应尚无统一的管理指导规范，在一定程度上降低甚至限制了ALKi的临床使用及患者获益。本文由四川省肿瘤学会肺癌专业委员会及四川省肿瘤性疾病医疗质量控制中心牵头，针对国内已经获批上市的ALKi，参考国内外临床研究和相关文献，并结合专家实践经验，总结出《ALKi不良反应管理专家建议（2021年版）》，以期为临床提供切实可行的ALKi不良反应的管理策略。 】 【中文关键词：间变性淋巴瘤激酶抑制剂；肺肿瘤；不良反应；专家建议】.
