ABSTRACT

As a treatment option for cancer, thermal ablation has satisfactory effects on many types of solid tumors (such as liver and renal cancers). However, its clinical applications for the treatment of thyroid nodules and metastatic cervical lymph nodes are still under debate both in China and abroad. In 2015, the “Zhejiang Expert consensus on thermal ablation for thyroid benign nodules, microcarcinoma, and metastatic cervical lymph nodes (2015 edition),” was released by the Thyroid Cancer Committee of Zhejiang Anti-Cancer Association, China. To further standardize the application of thermal ablation for thyroid tumors, the Thyroid Tumor Ablation Experts Group of Chinese Medical Doctor Association has organized many seminars and finally produced a consensus to formulate the “Expert consensus workshop report: Guidelines for thermal ablation of thyroid tumors (2019 edition).”

ABSTRACT

Objective: This study aimed to evaluate the safety and efficacy of thermal ablation in treating low-risk unifocal papillary thyroid microcarcinoma (PTMC). Materials and Methods: Patients with unifocal PTMC were enrolled in this study, and thermal ablations were performed. Contrast-enhanced ultrasound was used to estimate the extent of ablation immediately after thermal ablation; complications were recorded. The size and volume of the ablated area and thyroid hormones were measured, and the clinical evaluations were performed at 1, 3, 6, 12, and 18 months after thermal ablation. From July 2016 to July 2017, the prospective study was conducted involving 107 patients. Thermal ablation was well tolerated without serious complications. Results: Compared with the volume immediately after thermal ablation, the mean volume reduction ratio (VRR) of ablated lesions was 0.457 ± 0.218 (range: 0.040–0.979), 0.837 ± 0.150 (range: 0.259–1), 0.943 ± 0.090 (range: 0.491–1), 0.994–0.012 (range: 0.938–1), and 0.999 ± 0.002 (range: 0.992–1) at 1, 3, 6, 12, and 18 months after thermal ablation, respectively. Significant differences in the VRR were found between every two follow-up visits (P < 0.01). Results of patients' thyroid function test before thermal ablation and at 1 month after thermal ablation were normal, and no significant differences were observed (P > 0.05). No tumor regrowth, local recurrence, or distant metastases were detected during follow-up visits. Conclusion: Thermal ablation is a short-term safe and effective method in treating low-risk small PTMCs, which can be considered a potential alternative therapy for patients with PTMC
