Osteosarcoma - Childhood and Adolescence: Statistics

Approved by the Cancer.Net Editorial Board, 01/2020

ON THIS PAGE: You will find information about the number of children and teens who are diagnosed with osteosarcoma 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, in the United States, an estimated 800 to 900 people of all ages will be diagnosed with osteosarcoma, with about half being children and teens. About 2% of all childhood cancers are osteosarcoma. It is most often diagnosed between the ages of 10 and 30, with most diagnoses occurring in teens. However, osteosarcoma can be diagnosed at any age, including older adults.

The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. However, the rate depends on different factors, including the type and subtype of the cancer, the cancer’s response to treatment, and the degree to which the cancer has spread. The overall 5-year survival rate for children and teens with osteosarcoma is 69%. For people of all ages and stages, it is 60%.

If osteosarcoma is diagnosed and treated before it has spread outside the area where it started, the general 5-year survival rate for people of all ages is 77%. If the cancer has spread outside of the bones and into surrounding tissues or organs and/or the regional lymph nodes, the 5-year survival rate is 64%. If the cancer has spread to distant parts of the body, the 5-year survival rate is 27%%.

It is important to remember that statistics on the survival rates for children and teens with osteosarcoma are an estimate. The estimate comes from annual data based on the number of children and teens 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.
