Astrocytoma - Childhood: Statistics

Approved by the Cancer.Net Editorial Board, 01/2021

ON THIS PAGE: You will find information about the number of children and teens who are diagnosed with astrocytoma each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

This year, an estimated 830 children and teens younger than 19 will be diagnosed with astrocytoma in the United States. Pilocytic astrocytomas make up an estimated 15% of all brain and other CNS tumors in this age group.

The 5-year survival rate tells you what percent of children live at least 5 years after the tumor is found. Percent means how many out of 100. The 5-year survival rate for children and teens up to age 19 with pilocytic astrocytoma is 97%. For those with diffuse astrocytoma, the 5-year survival rate is almost 84%. The survival rate for anaplastic astrocytoma is slightly over 27%.

However, the grade of the astrocytoma affects survival rates. Other factors also affect survival rates, including how much of the tumor can be removed during surgery. Children with a type of astrocytoma that is unlikely to spread, called noninfiltrating astrocytoma, generally have a higher 5-year survival rate.

It is important to remember that statistics on the survival rates for children with astrocytoma are an estimate. The estimate comes from annual data based on the number of children with this cancer in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Talk with your child’s doctor if you have any questions about this information.
