What is the pathological countermeasure for hemisection of thyroid cancer

The pathological countermeasures for hemisection of thyroid cancer generally include pathological diagnosis, TBS grading, and neck lymph node dissection. It is also necessary to combine postoperative pathological diagnosis to determine whether there are microlesions.

1. Pathological diagnosis: During the operation, pathological examination is needed to clarify the type and stage of thyroid cancer, which will help determine the next treatment plan;

2. TBS grading: The TBS grading on the pathology report is generally based on the cell morphology of thyroid cancer and can be divided into four levels: I, II, III, and IV. The pathological grading after hemisection of thyroid cancer is based on the postoperative cytological pathology, mainly to see whether the pathological type of thyroid cancer is carcinoma in situ, microcarcinoma, medullary carcinoma, or undifferentiated carcinoma. For pathology graded as grade III, it means that the patient has a relatively good prognosis, and it is recommended to follow the doctor's advice for long-term follow-up examinations;

3. Neck lymph node dissection: It mainly involves complete thyroidectomy and lymph node dissection for thyroid cancer. The scope of surgery is mainly on both sides of the thyroid gland. Lymph node dissection can be performed after surgery, mainly to determine whether the lymph nodes have metastasized and to prevent the presence of residual tumor cells;

4. Postoperative pathology: Pathological examination after surgery can determine the type and stage of thyroid cancer, which is helpful for clarifying the next treatment plan. If the postoperative pathology indicates medullary carcinoma and there is a manifestation of nerve invasion, neck paratracheal lymph node dissection is also required.

It is also necessary to combine the postoperative pathological diagnosis to determine whether there are microlesions, that is, microlesions refer to thyroid cancer cells that cannot be seen by the naked eye, which may be cured through radiotherapy such as iodine-131 after surgery. Some patients may also have lymph node metastasis. If the metastasis range is large, radiotherapy such as iodine-131 is required after surgical clearance.
