Survival statistics for childhood Ewing sarcoma
Survival statistics for childhood Ewing sarcoma are general estimates and must be interpreted very carefully. These statistics are based on the experience of groups of children and can’t be used to predict a particular childʼs chances of survival.
There are many different ways to measure and report cancer survival statistics. Your child’s doctor can explain the statistics for Ewing sarcoma and what they mean for your child.
Overall survival
Overall survival is also called observed survival. Itʼs the percentage of people with a particular cancer who are alive at a certain point in time after their diagnosis. Doctors often use overall survival when they talk about a prognosis.
In Canada, a 5-year overall survival is not reported for childhood Ewing sarcoma. But it is included within the group “malignant bone tumours,” which includes other types of childhood bone cancer.
The 5-year overall survival for “malignant bone tumours” in children 0 to 14 years of age is 72%. This means that, on average, 72% of children diagnosed with malignant bone tumours are expected to live at least 5 years after their diagnosis.
Survival by stage
Survival varies with each stage of childhood Ewing sarcoma. Generally, the earlier Ewing sarcoma is diagnosed and treated, the better the outcome.
There are no specific Canadian statistics available for the different stages of Ewing sarcoma 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 those in Canada.
|
Stage |
5-year overall survival |
|---|---|
|
Localized (cancer has not spread to other parts of the body) |
84% |
|
Metastatic (cancer has spread to other parts of the body) |
50% |
Questions about survival
Talk to the doctor about prognosis. Prognosis depends on many factors, including:
- the type of cancer
- the stage
- certain characteristics of the cancer
- the treatments chosen
- how the cancer responds to treatment
Only a doctor familiar with these factors can put all of this information together with survival statistics to arrive at a prognosis.
