                    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. 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.   Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment.
                
                
                    Children with childhood soft tissue sarcoma should have their treatment planned by a team of health care providers who are experts 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 health care providers who are experts in treating children with soft tissue sarcoma 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:         -  Pediatrician.    -  Radiation oncologist.    -  Pediatric hematologist.    -  Pediatric nurse specialist.    -  Rehabilitation specialist.    -  Psychologist.    -  Social worker.    -  Child-life specialist.
                
                
                    Treatment for childhood soft tissue sarcoma may cause side effects.
                    For information about side effects that begin during treatment for cancer, see our Side Effects page.   Side effects from cancer treatment that begin after treatment and continue for months or years 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 effects cancer treatment can have on your child. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information.)
                
                
                    Eight types of standard treatment are used:
                    Surgery     Surgery to completely remove the soft tissue sarcoma is done when 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. This is called neoadjuvant therapy.    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 all or part of the limb or appendage with cancer, such as the arm or hand.     -  Lymphadenectomy: Removal of the lymph nodes with cancer.      -  Mohs surgery: A surgical procedure used to treat cancer in the skin. Individual layers of cancer tissue are removed and checked under a microscope one at a time until all cancer tissue has been removed. This type of surgery is used to treat dermatofibrosarcoma protuberans. It is also called Mohs micrographic surgery.     -  Hepatectomy: Surgery to remove all or part of the liver.           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 more tissue if needed.           If cancer is in the liver, a hepatectomy and liver transplant may be done (the liver is removed and replaced with a healthy one from a donor).    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 lower the risk that the cancer will come back, 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. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. This type of radiation therapy may include the following:                  -  Stereotactic body radiation therapy: Stereotactic body radiation therapy is a type of external radiation therapy. Special equipment is used to place the patient in the same position for each radiation treatment. Once a day for several days, a radiation machine aims a larger than usual dose of radiation directly at the tumor. By having the patient in the same position for each treatment, there is less damage to nearby healthy tissue. This procedure is also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.                -  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 and whether the tumor was completely removed by surgery. External and internal radiation therapy are used to treat childhood soft tissue sarcoma.       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 cerebrospinal fluid, 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 of cancer being treated.     Most types of soft tissue sarcoma do not respond to treatment with chemotherapy.    See Drugs Approved for Soft Tissue Sarcoma for more information.       Observation     Observation is closely monitoring a patients condition without giving any treatment until signs or symptoms appear or change. Observation may be done when:             - Complete removal of the tumor is not possible.     - No other treatments are available.     - The tumor is not likely to damage any vital organs.              Hormone therapy     Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances made 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 is used to reduce the production of hormones or block them from working. Antiestrogens (drugs that block estrogen), such as tamoxifen, may be used to treat desmoid-type fibromatosis.       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 desmoid-type fibromatosis, an NSAID called sulindac may be used to help block the growth of cancer cells.       Targeted therapy     Targeted therapy is a type of treatment that uses drugs or other substances to attack cancer cells. Targeted therapies usually cause less harm to normal cells than chemotherapy or radiation do.     Kinase inhibitors are a type of targeted therapy that block an enzyme called kinase (a type of protein). There are different types of kinases in the body that have different actions.             -  ALK inhibitors may stop the cancer from growing and spreading:                  -  Crizotinib may be used to treat inflammatory myofibroblastic tumor.                -  Tyrosine kinase inhibitors (TKIs) block signals needed for tumors to grow:                   -  Imatinib is used to treat dermatofibrosarcoma protuberans.       -  Pazopanib may be used to treat recurrent and progressive soft tissue sarcoma. It is being studied for many types of newly diagnosed soft tissue sarcoma.       - Sorafenib may be used to treat desmoid-type fibromatosis.                      New types of tyrosine kinase inhibitors are being studied such as LOXO-101 and entrectinib for infantile fibrosarcoma.    Other types of targeted therapy are being studied in clinical trials, including the following:            -  mTOR inhibitors are a type of targeted therapy that stops the protein that helps cells divide and survive. mTOR inhibitors are being studied to treat perivascular epithelioid cell tumors (PEComas) and epithelioid hemangioendothelioma. Sirolimus is a type of mTOR inhibitor therapy.      -  Angiogenesis inhibitors are a type of targeted therapy that prevent the growth of new blood vessels needed for tumors to grow. Angiogenesis inhibitors, such as cediranib, sunitinib, and thalidomide are being studied to treat alveolar soft part sarcoma and epithelioid hemangioendothelioma. Bevacizumab is being studied for blood vessel tumors.     -  Histone methyltransferase (HMT) inhibitors are targeted therapy drugs that work inside cancer cells and block signals needed for tumors to grow. HMT inhibitors are being studied for the treatment of epithelioid sarcoma, malignant peripheral nerve sheath tumor, extrarenal (extracranial) rhabdoid tumor, extraskeletal myxoid chondrosarcoma, and synovial sarcoma.      -  Heat-shock protein inhibitors block certain proteins that protect tumor cells and help them grow. Ganetespib is a heat shock protein inhibitor being studied in combination with the mTOR inhibitor sirolimus for malignant peripheral nerve sheath tumors that cannot be removed by surgery.     -  Antibody-drug conjugates are made up of a monoclonal antibody attached to a drug. The monoclonal antibody binds to specific proteins or receptors found on certain cells, including cancer cells. The drug enters these cells and kills them without harming other cells. Lorvotuzumab mertansine is an antibody-drug conjugate being studied for the treatment of rhabdomyosarcoma, malignant peripheral nerve sheath tumor, and synovial sarcoma.           See Drugs Approved for Soft Tissue Sarcoma for more information.       Immunotherapy     Immunotherapy is a treatment that uses the patients immune system to fight disease. Substances made by the body or made in a laboratory are used to boost, direct, or restore the bodys natural defenses against disease.     Interferon is a type of immunotherapy used to treat epithelioid hemangioendothelioma. It interferes with the division of tumor cells and can slow tumor growth.
                         
                
                    Follow-up tests may be needed.
                    Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.   Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
