Childhood thyroid cancer (carcinoma of thethyroid) increasing trend, Beijing Children's Hospital with pathologically confirmed 1,379 cases of malignant tumors in the thyroid cancer 10 cases (0.7%), while abroad report thyroid cancer patients, under the age of 15 accounted for about 3.7 percent to 5 percent, the largest seen at 10 ~ 14 years of age. More girls, the male to female ratio was 1:2 ~ 3.
The child is very sensitive to radiation on the thyroid gland, thyroid cancer patients with previous children in infancy because of benign lesions such as the thymus mast, hemangioma near accepts neck and regional radiotherapy were accounted for 80%, with these benign lesions do not radiotherapy, radiotherapy carcinogenic factors also vanished accordingly. 15 ~ 50% in children due to Hodgkin's disease, leukemia and other malignant diseases of head and neck radiotherapy and chemotherapy, occurred in the first year of thyroid stimulating hormone (TSH) increase, then 5 to 7 years 5% ~ 20% as thyroid function the lower. Generally after radiotherapy 3 to 5 years in thyroid carcinoma and 15 ~ 25-year-old to peak.
There are papillary thyroid carcinoma (papillary), follicular (follicular) or mixed tumor differentiation. These tumors often slow-growing, many years was a static state, and to accept or not to accept the radiotherapy course is the same, but the patients received radiotherapy see more multi-center of the tumor. About four percent of patients with papilloma home in the same patients. Extremely rare in children undifferentiated carcinoma, developing rapidly, leading to death.
