Survival rates for Ewing tumors by stage

Survival rates are often used by doctors as a standard way of discussing a person’s prognosis (outlook). Some people may want to know the survival statistics for those in similar situations, while others may not find the numbers helpful, or may even not want to know them. If you do not want to read about survival statistics for Ewing tumors, skip to the next section.

When discussing cancer survival statistics, doctors often use a number called the 5-year survival rate. The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed. Of course, many people live much longer than 5 years (and many are cured).

In order to get 5-year survival rates, doctors have to look at people who were treated at least 5 years ago. Improvements in treatment since then might result in a better outlook for patients now being diagnosed with Ewing tumors.

Survival rates are often based on previous outcomes of large numbers of people who had the disease, but they aren’t a prediction of what will happen in any person’s case. The stage of a person’s cancer is important in estimating their outlook. But many other factors can also affect a person’s prognosis, such as their age, the location of the tumor, and how well the cancer responds to treatment.

Localized tumors

With current treatment, the overall 5-year survival rate for patients with Ewing tumors that are still localized when they are first found is around 70%.

Metastatic tumors

When the cancer has already spread when it is diagnosed, the 5-year survival rate is about 15% to 30%. The survival rate is slightly better if the cancer has only spread to the lungs as opposed to having reached other organs.

Other factors affecting prognosis

Factors other than the stage of the cancer can also affect survival rates. Factors that have been linked with a better prognosis include:

  • Smaller tumor size
  • Main tumor is on an arm or leg (as opposed to chest wall or pelvis)
  • Normal blood LDH level
  • Good tumor response to chemotherapy
  • Age younger than 10

Even when taking these other factors into account, survival rates are at best rough estimates. Your child’s doctor is your best source of information on this topic, as he or she is familiar with your situation.
