Osteosarcoma - Childhood and Adolescence: Statistics

Approved by the Cancer.Net Editorial Board, 11/2016

ON THIS PAGE: You will find information about the number of people, including children, who are diagnosed with osteosarcoma each year. You will 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 1,000 people total, including 450 children and teens younger than 20, will be diagnosed with osteosarcoma in the United States. About 2% of all childhood cancers are osteosarcoma. It most often affects those between the ages of 10 and 30.

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 the type and subtype of the cancer, the cancer’s response to treatment, and the degree to which the cancer has spread. The 5-year survival rate for children and teens with osteosarcoma that is only in 1 place at the time of diagnosis is 70%.

If osteosarcoma is diagnosed and treated before it spread outside the area it is found, the general 5-year survival rate is between 60% to 80%. If the cancer has already spread at the time of diagnosis, the 5-year survival rate is between 15% and 30%. Osteosarcoma that has spread only to the lungs has a 5-year survival rate of approximately 40%.

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. People should talk with their child’s doctor if they have questions about this information.
