How many years can a patient live after surgery for thyroid metastatic lymphoma is mainly decided according to the patient’s pathological classification of thyroid malignant tumor, treatment situation and psychological state. 1. Pathological analysis: thyroid malignant tumors clinically include medullary carcinoma of thyroid, follicular carcinoma of thyroid, papillary carcinoma of thyroid, undifferentiated carcinoma of thyroid and so on. Papillary thyroid carcinoma and follicular thyroid carcinoma are prone to lymph node metastasis, but after resection, the 10-year survival rate can reach more than 90%; medullary carcinoma has a higher degree of malignancy, but after timely and standardized treatment, the 5-year survival rate can reach 70%; undifferentiated carcinoma has the highest degree of malignancy, and the average survival rate after diagnosis is about 3-6 months, and the 1-year survival rate is generally at 5%-15%. 2. Treatment: for patients with malignant tumor of thyroid gland, after early detection, early surgery, lymph node dissection and iodine 131 treatment, the survival period is relatively long. 3. Psychological state: the patient’s psychological state also determines the survival period, the psychological state is good, acceptance of their own suffering from the disease, relatively speaking, the survival period is obviously prolonged. For patients with malignant thyroid tumors, they should follow the doctor’s instructions to carry out appropriate treatment and regular review to prolong their lives as much as possible.
