First of all, it should be noted that without strict treatment indications, more and more units in China are currently performing this technique domestically. In 2012, experts of the Executive Committee of the Korean Society of Thyroid Radiology have reached a consensus that radiofrequency ablation can be used for the treatment of benign thyroid nodules and inoperable recurrent thyroid cancer, but it is not recommended for follicular thyroid tumors (FN) or primary thyroid cancer. The Italian consensus on radiofrequency ablation of thyroid nodules states that radiofrequency ablation may be recommended for benign thyroid nodules that meet certain indications and for recurrent thyroid cancer where surgery is contraindicated and I131 therapy is not effective, whereas follicular tumors or primary thyroid cancer are not indications for radiofrequency ablation. Ultrasound-guided percutaneous thermal ablation is a new minimally invasive treatment technique that produces thermal coagulation necrosis of localized lesions through puncture devices under real-time ultrasound monitoring. Since thermal ablation can effectively reduce the size of thyroid nodules, relieve nodule-related symptoms and avoid surgical trauma, it is used in the treatment of benign solid nodules in several clinical centers internationally, especially in Korea and Italy. In 2012, a consensus on radiofrequency ablation of thyroid nodules was published in Korea, and the recommended indications include 1) benign thyroid nodules with local symptoms such as neck pain or discomfort, dyspnea, foreign body sensation, and cough (self-measured by patients using a visual analog score of 0-10), 2) affecting appearance (self-measured appearance score: 1, no palpable mass; 2, palpable mass without (3) Autonomous functional nodules combined with hyperthyroidism; (2) Recurrent thyroid cancer, where the patient is a contraindication to surgery or refuses surgery; also, it is proposed that radiofrequency ablation is not recommended for follicular thyroid tumors and primary thyroid cancer. The Italian version of radiofrequency ablation of thyroid nodules is recommended for the following indications: (1) non-functional benign nodules (larger than 20 ml in volume) with local symptoms or affecting appearance, where surgery is contraindicated or refused; (2) autonomous functional nodules with hyperthyroidism or subclinical hyperthyroidism, where surgery or radioactive iodine therapy is contraindicated or refused; (3) inoperable recurrent thyroid cancer where radioactive iodine is ineffective 2. Relative indications (most agree): non-functional benign nodules (less than 20 ml in volume) with early local discomfort and rapid increase in size; 3. injection is preferred, (2) primary thyroid cancer or follicular tumor, surgery is the standard treatment.
