[Clinical practice guidelines:image-guided thermal ablation of primary and metastatic lung tumors (2021 edition)].

Image-guided thermal ablation (IGTA) has been applied in the treatment of primary and metastatic lung tumors, and the number of patients treated is increasing rapidly every year. The Ablation Expert Committee of the Chinese Society of Clinical Oncology, the Expert Group on Tumor Ablation Therapy of the Chinese Medical Doctors Association, the Tumor Ablation Committee of the Chinese College of Interventionalists, and the Society of Tumor Ablation Therapy of the Chinese Anti-Cancer Association provided the platform for multidisciplinary experts to formulate the"Clinical Practice Guidelines:Image-Guided Thermal Ablation of Primary and Metastatic Lung Tumors (2021 Edition)". The main contents of the Clinical Practice Guidelines include: (1)epidemiology of primary and metastatic lung tumors; (2) IGTA concepts and common technical features; (3) procedures, indications, contraindications, outcomes evaluation, and related complications of IGTA for primary and metastatic lung tumors.影像引导下热消融（image-guided thermal ablation，IGTA）技术已经广泛应用于原发性和转移性肺部肿瘤的治疗，每年治疗例数迅速增加。为了IGTA治疗原发性和转移性肺部肿瘤临床实践的规范和发展，由中国临床肿瘤学会（CSCO）肿瘤消融治疗专家委员会、中国医师协会肿瘤消融治疗技术专家组、中国抗癌协会肿瘤消融治疗专业委员会、中国医师协会介入医师分会肿瘤消融学组，组织国内有关专家，在2014年版和2017年版“热消融治疗原发性和转移性肺部肿瘤专家共识”基础上，讨论制定了“影像引导下热消融治疗原发性和转移性肺部肿瘤临床实践指南（2021年版）”。主要内容包括：（1）原发性和转移性肺部肿瘤流行病学情况；（2）IGTA概念和常用技术特点；（3）IGTA治疗原发性和转移性肺部肿瘤技术操作规程、适应证、禁忌证、疗效评价和相关并发症。.
