Brief Summary: Prospective randomized open phase III non-inferiority trial in cT1bN0N1aM0 isthmus tumors of the thyroid comparing: extended Isthmusectomy (Isthmusectomy + Central Neck Dissection)(experimental group) versus total thyroidectomy + Central Neck Dissection (reference group).
Detailed Description: The thyroid isthmus is a narrow structure connecting the two lobes of the thyroid. Papillary carcinoma arising from this site accounts for only 1-9% of all thyroid cancers. However, due to its unique anatomical location, it is more prone to extranodal extension and bilateral lymph node metastasis, exhibiting more aggressive biological behavior. The optimal extent of surgery remains controversial: total thyroidectomy facilitates postoperative radioactive iodine therapy and monitoring but results in permanent dependence on thyroid hormone replacement and increases the risk of complications such as hypocalcemia, adversely affecting patients' quality of life. In contrast, conservative approaches like extended isthmusectomy can preserve partial thyroid function, reduce complications, and maintain a better quality of life, making them particularly suitable for low-risk patients with small tumors and no metastasis. Existing retrospective studies indicate no significant difference in recurrence rates between the two surgical approaches, though the evidence remains limited. Therefore, this study aims to conduct a prospective, multicenter, open-label, parallel-controlled, randomized trial to directly compare total thyroidectomy and extended isthmusectomy in terms of postoperative recurrence rates, quality of life, and complications, thereby providing high-quality evidence for surgical decision-making.
