A prospective cohort of papillary thyroid carcinoma(PTC), patients who received thermal ablation in our hospital since February 2023 was established as the study object. Preoperative and postoperative demographic data, ultrasonography, other relevant laboratory tests, and thyroid disease-related scales such as fatigue, depression, and stress were collected. The influencing factors of PTC recurrence were analyzed.

Inclusion Criteria:

①≥18 years old; ② Obtain informed consent; ③ Ultrasonography showed that malignant nodules were single, the maximum diameter of nodules was ≤1cm and the distance from the capsule was ≥2mm. ④ no lymph node metastasis or other extra-glandular metastasis in the neck; ⑤ PTC was confirmed by fine needle puncture pathology; ⑥ Patients who do not meet Article 3, who still strongly request thermal ablation while fully informing the patient of the risk of recurrence, and who have been clinically assessed to be technically capable of thermal ablation Exclusion Criteria:① Pregnant or lactating patients; ② Patients with other malignant tumors and not suitable for ablation by clinical evaluation; ③ Patients who cannot tolerate surgery; ④ Patients with cognitive impairment and other conditions who cannot accurately fill in thyroid-related questionnaires.

Patients with pathologically proven PTC underwent ultrasound-guided percutaneous thermal ablation.
