What is the recurrence rate after hemisection of thyroid cancer?

The recurrence rate after hemisection of thyroid cancer cannot be generalized. The recurrence rate of patients with different pathological types of thyroid cancer is also different. Clinically, thyroid cancer mainly includes papillary thyroid cancer, follicular thyroid cancer, medullary thyroid cancer and anaplastic thyroid cancer.

1. Papillary thyroid cancer: It is the most common thyroid cancer with low malignancy. The disease-free survival rate of most patients after surgery is 98% after 10 years, and the 10-year survival rate is 75%, which means that 80% of patients will not relapse. Therefore, the recurrence rate of papillary thyroid cancer after hemisection is low.

2. Follicular thyroid cancer: The prognosis is worse than that of papillary thyroid cancer, but the recurrence rate in the contralateral and contralateral thyroid gland is still low. 20% of patients will relapse within 10 years, and some patients may have cervical lymph node metastasis;

3. Medullary thyroid cancer: It is a malignant tumor originating from the parafollicular cells of the thyroid gland. It is relatively common. Cancer cells can secrete a variety of amines and hormones, as well as 5-hydroxytryptamine, histamine, prostaglandins and adrenocorticotropic hormone-like substances, which can cause patients to have intractable diarrhea. After surgical treatment, the 5-year survival rate of patients with early medullary thyroid cancer is 50%, and the 10-year survival rate is 20%.

4. Anaplastic thyroid cancer: It refers to a malignant tumor originating from the thyroid follicular epithelium or parafollicular cells. It is rare. Cancer cells can secrete a variety of amines and hormones, as well as 5-hydroxytryptamine, histamine, prostaglandins and adrenocorticotropic hormone-like substances, which can cause patients to have intractable diarrhea. Advanced patients may metastasize to the lungs, bones and other parts. Since anaplastic cancer progresses rapidly and has a poor prognosis, the recurrence rate of anaplastic thyroid cancer after hemisection is high.

It is recommended that patients diagnosed with thyroid cancer should undergo surgical treatment in a timely manner. After surgery, the pathological examination results should also be used to determine whether adjuvant radiotherapy, chemotherapy and other treatment measures are needed to reduce the recurrence rate.
