How often do I need to be rechecked after pediatric thyroid surgery? It is recommended to review every six months after surgery. What are the main items to be reviewed? Calcitonin in the blood is the most important indicator of the presence of tumor. Generally speaking, calcitonin can be reduced to normal level after surgery. If the tumor has recurred, calcitonin will increase. Carcinoembryonic antigen is also a reference indicator. What is the prognosis of the child after surgery? The outcome of treatment depends on the early detection of the disease; the cure rate for children with stage I is almost 100%, while the cure rate for children with stage III or IV is only 45%-55%. Is there any difference between a child with early surgery and a normal child? As long as the surgery is successful, the patient’s life and schooling are no different from those of a normal child. Life expectancy is also not affected. What is the rate of recurrence or metastasis after surgery? The recurrence rate will be more than 30% for all patients without differentiating staging. Do you have any suggestions for the treatment of pediatric medullary thyroid cancer for better outcomes? As a parent, it is important to consider the survival of the child while focusing on the safety of the surgery. Many parents are most concerned about discrimination against their child because of hereditary medullary thyroid cancer or the impact on their future marriage. In this regard, parents should be reassured. This disease is not 100% hereditary. Secondly, early treatment will ensure the life safety of the child. It is not certain that the disease will be inherited in the future, and it is possible to lift the “spell” of inheritance from generation to generation. Even if the disease is inherited, prenatal testing of the amniotic fluid can be used to determine if there is a RET gene mutation and to choose whether to keep the fetus. With the development of modern medicine, parents should be assured that their children will undergo early specialized thyroid surgery.
