Follicular tumors of undetermined malignant potential of the thyroid gland are mainly treated by surgical resection, lymph node dissection and radionuclide therapy. 1. Surgical resection: If the diameter of the follicular tumor of undetermined malignant potential of thyroid is larger than 4 cm and the pathological diagnosis is malignant, it needs to be surgically resected in time, and usually total or subtotal resection will be chosen according to the condition of the patient. 2. Lymph node dissection: if there are lymph node metastases around the follicular tumor, lymph node dissection is also needed, and the scope of dissection should be decided according to the scope of metastases and the degree of organ involvement. 3. Radionuclide therapy: it is mainly applied to patients with residual lesions after surgical resection, and radionuclide iodine 131 therapy can be applied to the residual lesions. 4. Drug therapy: taking thyroxine tablets and levothyroxine tablets to replace thyroxine therapy. To summarize, after being treated with the above therapeutic measures, it is necessary to regularly review the recurrence of thyroid cancer and the thyroid-related hormones in the body, so as to avoid delaying the condition.
