Cure Rate

Hyperthyroidism is a clinical syndrome caused by excessive production of thyroid hormones, leading to accelerated metabolism and increased excitability of multiple organ systems. Patients commonly present with polyphagia, weight loss, palpitations, and sweating. Primary hyperthyroidism is a common endocrine disorder traditionally treated with anti-thyroid drugs (ATD), radioactive iodine (¹³¹I), or surgery. While ATD can rapidly inhibit thyroid hormone synthesis and control symptoms, long-term use carries risks of liver damage and bone marrow suppression. Radioactive iodine involves risks of recurrence or permanent hypothyroidism, and thyroidectomy-though effective-is associated with significant trauma, potential complications, and cervical scarring. Given the limitations of these monotherapies, a combined approach leveraging thermal ablation as an adjunct to antithyroid drug therapy has emerged as a promising strategy for both rapid symptom control and long-term management. With advances in minimally invasive techniques, thermal ablation combined with pharmacotherapy offers a balanced solution. Thermal ablation-including microwave and radiofrequency ablation-provides high precision, minimal invasiveness, and rapid recovery by directly destroying hyperfunctioning thyroid tissue under ultrasound guidance. When paired with a tailored antithyroid drug regimen, this approach not only secures immediate stabilization of thyroid function but also reduces the required drug dosage and duration, thereby mitigating drug-related adverse effects. This combined strategy maintains the cosmetic and cost-effective advantages of ablation while addressing the need for sustained endocrine control. Studies have demonstrated that thermal ablation combined with antithyroid drugs effectively normalizes T3 and T4 levels, alleviates hypermetabolic symptoms such as palpitations and sweating, and significantly improves quality of life with a low complication rate. This integrated model is suitable for initial treatment, recurrent or refractory cases, and is particularly advantageous for patients with reduced cardiopulmonary reserve or advanced age. However, current evidence is largely derived from single-center studies, and high-quality multicenter data are needed to validate this combined strategy. This study aims to prospectively collect baseline data from patients undergoing thermal ablation in conjunction with antithyroid drug therapy across multiple centers. The objectives are to evaluate the efficacy and safety of this combined modality, explore the factors influencing the prognosis of ablation in a medicated context, optimize postoperative medication adjustment protocols, and provide high-quality evidence to guide the standardization and clinical dissemination of this synergistic approach.

This study is a prospective, multicenter study designed to compare the efficacy and safety of surgical treatment versus ablation therapy (including radiofrequency ablation and microwave ablation) for patients with primary hyperparathyroidism (PHPT). The study will assess the impact of both treatment modalities on serum parathyroid hormone (iPTH) and calcium levels, clinical symptom improvement, bone mineral density enhancement, reduction in the incidence of urinary system stones, and postoperative complication rates. While surgical treatment has been the standard of care for PHPT, offering definitive cure, it carries inherent surgical risks and complications. Ablation therapy, as a minimally invasive approach, presents a novel alternative with reduced trauma and fewer complications. The outcomes of this study will inform clinical decision-making and potentially optimize treatment strategies for patients with PHPT.
