Thyroid cancer metastatic lymph can be treated by surgery, radiotherapy and targeted drug therapy. 1. Surgery: patients can clear lymph nodes through surgery again and remove all metastatic lymph nodes and lymph nodes in the neck through surgical treatment, so as to improve the survival rate of patients. 2. Radiation therapy: after oral administration of radioactive 131 iodine, the thyroid gland and residual tissues will highly take up the drug, and at the same time, iodine 131 releases beta rays at a low and continuous dose to kill the lymph nodes that have not been cut cleanly. 3. Targeted drug therapy: patients can take Sorafenib tosylate tablets and other targeted drug therapy as prescribed by the doctor. Sorafenib tosylate tablets contain Sorafenib, which can inhibit the proliferation of tumor cells and anti-angiogenesis, so that the uncut tumors and possible residual metastatic lymph nodes can be reduced in size. Sorafenib has a high binding rate to human plasma proteins, so patients suffering from hypertension and allergic to sorafenib are prohibited from taking this drug. If the metastatic lymph of thyroid cancer is not cut cleanly, you should consult a doctor for timely examination and take appropriate treatment according to the doctor’s advice. Patients should follow the doctor’s instructions to correctly use the drug, do not use the drug privately.
