Abstract    Papillary thyroid carcinoma is generally considered to have low biological invasiveness and a good overall prognosis. Papillary thyroid carcinoma located in the isthmus has more aggressive features than which located in the glands, including more frequent extra-thyroid infiltration, lymph node metastasis, and multifocality. Surgical is the best treatment for papillary carcinoma of the thyroid isthmus. At present, the preoperative examination cannot confirm whether the lymph nodes have metastasized. Therefore, there are many controversies regarding the scope of resection and lymph node dissection for thyroid papillary carcinoma in the isthmus. Combined with literature on the selection of different surgical treatment for different conditions, such as tumor size, multifocality, and lymph node metastasis, it is expected to provide clinicians with new ideas for the diagnosis and treatment of thyroid papillary carcinoma in the isthmus.
