Thyroid cancer metastasis

There are many types of common diseases in life. The choice of method is very critical in the treatment of diseases, especially for the treatment of some complex diseases, which requires a good method. This will only be helpful for the stability of the disease. The metastasis of thyroid cancer is very harmful to the patient's body. The thyroid itself is a very complex disease, and the treatment of this type of disease requires a long time.

So what exactly will happen if thyroid cancer metastasizes? Many people are not very clear about this issue. The following is a detailed introduction so that you can have a good understanding of what will happen after the disease metastasizes.

Thyroid cancer metastasis:

When the tumor metastasizes to the lymph nodes, the most common site is the middle and lower deep cervical lymph nodes, where enlarged lymph nodes can be felt.

The relationship between thyroid cancer recurrence and tumor size and infiltration: the recurrence rate of microcancer with a tumor diameter of <1.0cm is only 8.33%; while the recurrence rates of thyroid cancer with a diameter of 1.0-3.0cm and >3.0cm are 43.55% and 44.12% respectively; the recurrence rate of extracapsular infiltration is 45.10%; and the recurrence rate of intracapsular growth is 19.57%. Tip: When the tumor grows within a certain limit (diameter <1.0cm), the infiltration of cancer cells and the formation of hidden foci are restricted; if the tumor volume exceeds a certain range ≥1.0cm, the chances of capsule infiltration, multicentric cancer foci and lymph node metastasis increase, making it difficult to completely remove the tumor by surgery, thus increasing the recurrence rate.

The relationship between recurrence and metastasis of thyroid cancer: The biological characteristic of thyroid cancer is that it is easy to metastasize to the cervical lymph nodes. The literature reports that its metastasis rate is 50% to 90.5%. However, no enlarged lymph nodes were touched before thyroid cancer surgery, but the metastasis rate was 72.02% through postoperative pathological examination after cervical dissection. The cervical lymph node metastasis rate was 64.56%; the postoperative recurrence rate was 44.12%, and the postoperative recurrence rate without metastasis was 17.86%. This shows that for patients with cervical lymph node metastasis, the incidence of occult cancer lesions increases and the recurrence rate also increases. Therefore, for thyroid cancer that is prone to metastasis, preventive neck dissection should be performed; if the patient undergoes a repeat surgery, neck dissection should be performed if lymph node metastasis was confirmed during the first surgery. It is believed that the tumor-free principle should be strictly followed during surgery, and irregular operations are strictly prohibited to prevent iatrogenic implantation.

Through the above introduction, we have some understanding of thyroid cancer metastasis. After such a disease occurs, it needs to be treated in time. There are many common diseases in life. Simple diseases are mainly colds, fevers, and coughs. However, when treating these diseases, good methods are also needed to improve the disease.
