Survival statistics for childhood Ewing sarcoma of the bone

Survival statistics for childhood Ewing sarcoma of the bone are very general estimates and must be interpreted very carefully. These statistics are based on the experience of groups of children and cannot be used to predict a particular child’s chances of survival.

There are many different ways to measure and report cancer survival statistics. Your child’s doctor can explain the statistics for childhood Ewing sarcoma of the bone and what they mean for your child.

Observed survival

Observed survival is also called overall survival. It is the percentage of children with a certain type of cancer who are expected to live for at least a specified period of time after their diagnosis. Doctors often use the observed survival rate when they talk about a prognosis.

The 5-year observed survival for localized Ewing sarcoma of the bone in children 0–14 years of age is 70%. This means that, on average, 70% of children diagnosed with Ewing sarcoma of the bone are expected to live at least 5 years after their diagnosis.

Observed survival does not consider the cause of death. But of the 30% of children who don’t survive 5 years, most die from the cancer rather than from other causes.

Survival by stage

Survival varies with each stage of childhood Ewing sarcoma of the bone. Generally, the earlier Ewing sarcoma of the bone is diagnosed and treated, the better the outcome.

Generally, if doctors can completely remove the tumour, the outcome is better. But Ewing sarcoma does respond well to radiation therapy. Radiation therapy and surgery can often be combined to give effective local treatment, along with neoadjuvant chemotherapy, which can improve the success of local therapies.

There are no specific Canadian statistics available for the different stages of Ewing sarcoma of the bone in children. The following information comes from a variety of sources. It may include statistics from other countries that are likely to have similar outcomes as in Canada.

Questions about survival

Talk to the doctor about prognosis. Prognosis depends on many factors, including the:

  • child’s medical history
  • type of cancer
  • stage of the cancer
  • characteristics of the cancer
  • treatments chosen
  • response to treatment

Only a doctor familiar with these factors can put all of this information together with survival statistics to arrive at a prognosis.
