How much should TG be controlled after hemisection of thyroid cancer

After hemisection of the thyroid cancer, it is generally necessary to control the level of TSH (thyroid stimulating hormone), but the specific amount to be controlled still needs to be comprehensively judged based on the pathological diagnosis after thyroid cancer surgery.

1. Low-risk type: If the pathological diagnosis is thyroid cancer, and it is low-risk thyroid cancer, it is generally recommended to control the TSH level to 2-4mIU/L, and choose whether to perform iodine-131 treatment based on the patient's specific condition;

2. High-risk type: If the pathological diagnosis is high-risk thyroid cancer, the TSH level needs to be controlled to 3-4mIU/L, and the thyroid color Doppler ultrasound should be regularly reviewed after treatment, and regular examinations should be conducted at 3 months, 6 months, and 1 year. If there is no recurrence or metastasis, clinical cure can be considered;

3. Intermediate- and low-risk types: If the pathological diagnosis is intermediate- and low-risk thyroid cancer, in order to reduce the recurrence rate after surgery, the TSH level needs to be controlled to at least 4-6mIU/L, and the patient is recommended to take levothyroxine sodium tablets for life.

For patients with thyroid cancer, the higher the TSH level, the better. If it is in the early stage of thyroid cancer and there is no lymph node metastasis or lung metastasis, there is no need for special treatment of thyroglobulin after surgery. Instead, regular color Doppler ultrasound and thyroid function tests are sufficient. However, if the patient has already developed tumor metastasis or thyroid dysfunction, levothyroxine sodium tablets are required for replacement therapy. Patients should avoid eating spicy and irritating foods, and eat less iodized salt, kelp and other high-iodine foods to avoid irritating the lesions and hindering recovery.
