There are different types of treatment for patients with childhood soft tissue sarcoma.
Different types of treatments are available for patients with childhood soft tissue sarcoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. Before starting treatment, patients may want to think about taking part in a clinical trial. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment.
Clinical trials are taking place in many parts of the country. Information about ongoing clinical trials is available from the NCI Web site. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team.
Children with childhood soft tissue sarcoma should have their treatment planned by a team of doctors with expertise in treating cancer in children.
Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other pediatric doctors who are experts in treating children with cancer and who specialize in certain areas of medicine. These may include a pediatric surgeon with special training in the removal of soft tissue sarcomas. The following specialists may also be included:
Some cancer treatments cause side effects months or years after treatment has ended.
Some cancer treatments cause side effects that continue or appear months or years after cancer treatment has ended. These are called late effects. Late effects of cancer treatment may include:
- Physical problems.
- Changes in mood, feelings, thinking, learning, or memory.
- Second cancers (new types of cancer).
Some late effects may be treated or controlled. It is important to talk with your child's doctors about the possible late effects caused by some treatments. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information.)
Seven types of standard treatment are used:
Surgery
Surgery to completely remove the soft tissue sarcoma is done whenever possible. If the tumor is very large, radiation therapy or chemotherapy may be given first, to make the tumor smaller and decrease the amount of tissue that needs to be removed during surgery. The following types of surgery may be used:
- Wide local excision: Removal of the tumor along with some normal tissue around it.
- Amputation: Surgery to remove part or all of a limb or appendage, such as the arm or hand.
- Limb-sparing surgery: Removal of the tumor in an arm or leg without amputation, so the use and appearance of the limb is saved. Radiation therapy or chemotherapy may be given first to shrink the tumor. The tumor is then removed in a wide local excision. Tissue and bone that are removed may be replaced with a graft using tissue and bone taken from another part of the patient's body, or with an implant such as artificial bone.
- Lymphadenectomy: Removal of the lymph nodes that contain cancer.
- Thoracotomy: An operation to open the chest. This may be done to remove cancer that has spread to the lungs.
A second surgery may be needed to:
- remove any remaining cancer cells.
- check the area around where the tumor was removed for cancer cells and then remove them.
Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given radiation therapy or chemotherapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to increase the chances of a cure, is called adjuvant 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. The way the radiation therapy is given depends on the type and stage of the cancer being treated.
Chemotherapy
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is the use of more than one anticancer drug. The way the chemotherapy is given depends on the type and stage of the cancer being treated.
Hormone therapy
Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances produced by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy are used to reduce the production of hormones or block them from working. Antiestrogens (drugs that block estrogen) may be used to treat childhood soft tissue sarcoma.
Watchful waiting
Watchful waiting is closely monitoring a patient’s condition without giving any treatment until symptoms appear or change. Watchful waiting may be done when complete removal of the tumor is not possible, no other treatments are available, and the tumor does not place any vital organs in danger.
Nonsteroidal anti-inflammatory drugs
Nonsteroidal anti-inflammatory drugs (NSAIDs) are drugs (such as aspirin, ibuprofen, and naproxen) that are commonly used to decrease fever, swelling, pain, and redness. In the treatment of soft tissue sarcomas, an NSAID called sulindac may be used to help block the growth of cancer cells.
Liver transplant
The liver is removed and replaced with a healthy one from a donor.
New types of treatment are being tested in clinical trials. These include the following:
Targeted drug therapy
Targeted therapy is type of treatment that uses drugs or other substances to find and attack specific cancer cells without harming normal cells. Imatinib (Gleevec) is a new type of targeted therapy called a tyrosine kinase inhibitor. It finds and blocks an abnormal protein on cancer cells that causes them to divide and grow.
This summary section refers to specific treatments under study in clinical trials, but it may not mention every new treatment being studied. Information about ongoing clinical trials is available from the NCI Web site.
