Ewing Sarcoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview

continued...

Chemotherapy is part of the treatment for all patients with Ewing tumors. It is usually given to kill any tumor cells that have spread to other parts of the body. Chemotherapy may also be given to shrink the tumor before surgery or radiation therapy.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.

External radiation therapy is used to treat Ewing sarcoma.

Radiation therapy is used when the tumor cannot be removed by surgery or when surgery to remove the tumor will affect the way the child will look or important body functions. It is used to make the tumor smaller and decrease the amount of tissue that needs to be removed during surgery. It may also be used to treat tumors that have spread to other parts of the body.

Surgery

Surgery is usually done to remove cancer that is left after chemotherapy or radiation therapy. When possible, the whole tumor is removed by surgery. Tissue and bone that are removed may be replaced with a graft, which uses tissue and bone taken from another part of the patient's body or a donor. Sometimes an implant, such as artificial bone, is used.

Even if the doctor removes all of the cancer that can be seen at the time of the operation, chemotherapy or radiation therapy may be given after surgery to kill any cancer cells that are left. Chemotherapy or radiation therapy given after surgery to lower the risk that the cancer will come back is called adjuvant therapy.

New types of treatment are being tested in clinical trials.

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.

Chemotherapy with stem cell transplant

This treatment is a way of giving high doses of chemotherapy to kill cancer cells and then replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the bone marrow or blood of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.

Targeted therapy

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells.
