Ultrasound-guided thermal ablation of papillary thyroid cancer (PTC) has been promoted in clinical practice over the past few years. Thermal ablation has the advantages of being minimally invasive, effective, and safe. However, current guidelines and consensus only focus on low-risk papillary thyroid microcarcinoma. With growing clinical application and accumulating scientific research in thermal ablation for PTC, there is considerable evidence to demonstrate that thermal ablation can treat larger PTC tumors and benefit more patients with PTC. To expand the indications and standardize the technical details and perioperative patient management for PTC ablation, experts from the Society of Tumor Ablation Therapy of the Chinese Anti-Cancer Association, the Ablation Expert Committee of the Chinese Society of Clinical Oncology (CSCO), Chinese Medical Doctor Association College of Interventionalists Tumor Ablation Committee, and Chinese Bethune Spirit Research Association Endocrinology and Diabetes Branch Interventional Endocrine Committee discussed and developed a consensus on thermal ablation of PTC based on the latest research results. This consensus aims to promote the rapid development of thermal ablation for PTC in the clinic.
