[Expert consensus on key clinical issues related to percutaneous cryoablation for lung tumors (2026 edition)]

With the rapid development of image-guided minimally invasive therapeutic techniques, percutaneous cryoablation has become increasingly important in the comprehensive management system of pulmonary tumors due to its advantages such as good repeatability and minimal damage to surrounding structures. This consensus was developed by a working group consisting of multidisciplinary experts from respiratory and critical care medicine, interventional radiology, thoracic surgery, oncology, and ultrasound. Based on a systematic search of relevant domestic and international literature, synthesis of the latest guidelines and consensus statements, and combined with clinical practice experience in China, the group formulated 10 consensus recommendations through multiple rounds of expert discussion and voting. The contents cover the indications and contraindications of percutaneous cryoablation for lung tumors, pre-procedural biopsy strategies, application scenarios and timing of intervention in advanced lung cancer, key technical points of cryoablation, management principles for lesions of different numbers and sizes, as well as key practical aspects such as post-operative follow-up and evaluation processes and prevention and treatment strategies for complications. This consensus clarifies the role of percutaneous cryoablation in the comprehensive management of lung tumors and emphasizes that it should be performed in a standardized manner under the evaluation of a multidisciplinary team (MDT) to optimize the whole-course management pathway for patients with lung cancer. High-quality clinical research is still needed in the future to further refine standardized operating procedures and evidence-base, thereby providing references for clinical practice.
