Astrocytoma - Childhood: Statistics

Approved by the Lineagotica Editorial Board, 05/2017

ON THIS PAGE: You will find information about the number of children 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 1,200 children and adolescents younger than 19 will be diagnosed with astrocytoma in the United States. About 35% of childhood brain tumors are astrocytomas.

The grade of the astrocytoma affects survival rates. 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 young adults up to age 19 with pilocytic astrocytoma is about 97%. For those with diffuse astrocytoma and anaplastic astrocytoma, the 5-year survival rates are about 84% and 28%, respectively. Other factors that affect survival rates include 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. People should talk with their child’s doctor if they have any questions about this information. 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. Learn more about understanding statistics.
