Lymphatic metastasis of thyroid cancer indicates that the patient’s condition has entered the middle or advanced stage, and the survival period is reduced, with 5-year survival rate of about 90% and 10-year survival rate of about 80%. After lymphatic metastasis occurs in thyroid cancer, it is difficult to cure completely, not only need to surgically remove the lesion, clear the related lymph nodes, but also need to carry out iodine-131 radiotherapy, chemotherapy (such as paclitaxel, carboplatin, etc.), as well as targeted drug therapy, immunotherapy and other comprehensive treatment programs to prevent the cancer from further spreading, so as to prolong the survival period. Due to the removal of the thyroid gland during the surgery, lifelong levothyroxine tablets are needed to maintain the treatment after the surgery. In addition, surgery often damages the parathyroid glands, which requires regular blood calcium testing. When there is no lymph node metastasis in the early stage of thyroid cancer, thyroid cancer can be cured clinically by radical treatment of surgical resection, and patients will usually have a longer survival period. Patients are advised to have regular medical checkups to detect thyroid or neck abnormalities as early as possible so that they can be handled as early as possible to prolong the survival period. Medications should be applied under the guidance of a doctor.
