Ewing’s sarcoma

Definition:

Ewing's sarcoma is a malignant (cancerous) bone tumor  that affects children.



Alternative Names:

Ewing's family of tumors; Primitive neuroectodermal tumors (PNET)



Causes, incidence, and risk factors:

Ewing's sarcoma can occur any time during childhood and young adulthood, but usually develops during puberty, when bones are growing rapidly. It is 10 times as common in Caucasian children as in African-American, African, and Asian children.

The tumor may start anywhere in the body, usually in the long bones of the arms and legs, the pelvis, or the chest. It may also develop in the skull or the flat bones of the trunk.

The tumor often spreads (metastasis ) to the lungs and other bones. Spread at the time of diagnosis is seen in about one-third of children with Ewing's sarcoma.

Rarely, Ewing's sarcoma can occur in adults.



Symptoms:

There are few symptoms. The most common is pain and occasionally swelling at the site of the tumor.

Children may also break a bone at the site of the tumor after a seemingly minor injury (this is called a "pathologic fracture").

Fever may also be present.



Signs and tests:

If a tumor is suspected, tests to locate the primary tumor and any spread (metastasis) often include:



Treatment:

Treatment should be done by a cancer specialist (oncologist) and often includes a combination of:



Support Groups:

For additional information and resources, see cancer support group .



Expectations (prognosis):

How well a patient does depends on:

  • The location of the tumor
  • If the cancer has spread

The best chance for cure is with a combination of treatments that includes chemotherapy plus radiation or surgery, provided at a center that frequently treats this type of cancer.



Complications:

The treatments needed to fight this disease have many complications, which should be discussed on an individual basis.



Calling your health care provider:

Call your health care provider if your child has any of the symptoms of Ewing's sarcoma. An early diagnosis can increase the possibility of a favorable outcome.



Prevention:
