Juvenile thyroid cancer is known to have a high recurrence rate. The rate may be as high as 40% in patients less than 20 years of age and higher within the first 7 years of diagnosis.
Twenty year recurrence free survival is about 10% in patients diagnosed at age 10 or less. In fact, age is a major determinant of risk of recurrence, particularly in those younger than 10 years.
Overall younger patients have a poorer prognosis than those diagnosed later in life. In spite of these data, it should be emphasized that prognosis is still excellent with an overall survival rate of
95% for over a 12.9 years of follow-up in large series. Five and ten year survival rates in pediatric patients with thyroid cancer have been reported as high as 98-99%. However, the mortality rate may
become significant in cases with distant metastasis or recurrent disease. In the latter, the cumulative mortality rate varies from 30-58% in a period of 12-20years”
