                    There are different types of treatment for patients with osteosarcoma or malignant fibrous histiocytoma (MFH) of bone.
                    Different types of treatment are available for children with osteosarcoma or malignant fibrous histiocytoma (MFH) of bone. 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 osteosarcoma or MFH 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 pediatric health care providers who are experts in treating osteosarcoma and MFH and who specialize in certain areas of medicine. These may include the following specialists:         -  Pediatrician.    - Orthopedic surgeon.    -  Radiation oncologist.    -  Rehabilitation specialist.    -  Pediatric nurse specialist.    -  Social worker.    -  Psychologist.
                
                
                    Treatment for osteosarcoma or malignant fibrous histiocytoma 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 the following:         - 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).
                
                
                    Four types of standard treatment are used:
                    Surgery     Surgery to remove the entire tumor will be done when possible. Chemotherapy may be given before surgery to make the tumor smaller. This is called neoadjuvant chemotherapy. Chemotherapy is given so less bone tissue needs to be removed and there are fewer problems after surgery.     The following types of surgery may be done:            -  Wide local excision: Surgery to remove the cancer and some healthy tissue around it.     -  Limb-sparing surgery: Removal of the tumor in a limb (arm or leg) without amputation, so the use and appearance of the limb is saved. Most patients with osteosarcoma in a limb can be treated with limb-sparing surgery. The tumor is removed by 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. If a fracture is found at diagnosis or during chemotherapy before surgery, limb-sparing surgery may still be possible in some cases. If the surgeon is not able to remove all of the tumor and enough healthy tissue around it, an amputation may be done.     -  Amputation: Surgery to remove part or all of an arm or leg. This may be done when it is not possible to remove all of the tumor in limb-sparing surgery. The patient may be fitted with a prosthesis (artificial limb) after amputation.     -  Rotationplasty: Surgery to remove the tumor and the knee joint. The part of the leg that remains below the knee is then attached to the part of the leg that remains above the knee, with the foot facing backward and the ankle acting as a knee. A prosthesis may then be attached to the foot.           Studies have shown that survival is the same whether the first surgery done is a limb-sparing surgery or an amputation.    Even if the doctor removes all the cancer that can be seen at the time of the surgery, patients are also given chemotherapy after surgery to kill any cancer cells that are left in the area where the tumor was removed or that have spread to other parts of the body. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.       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 and stage of the cancer being treated.    In the treatment of osteosarcoma and malignant fibrous histiocytosis of bone, chemotherapy is usually given before and after surgery to remove the primary tumor.    See Drugs Approved for Bone Cancer for more information.       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.    Osteosarcoma and MFH cells are not killed easily by external radiation therapy. It may be used when a small amount of cancer is left after surgery or used together with other treatments.       Samarium     Samarium is a radioactive drug that targets areas where bone cells are growing, such as tumor cells in bone. It helps relieve pain caused by cancer in the bone and it also kills blood cells in the bone marrow. It also is used to treat osteosarcoma that has come back after treatment in a different bone.    Treatment with samarium may be followed by stem cell transplant. Before treatment with samarium, stem cells (immature blood cells) are removed from the blood or bone marrow of the patient and are frozen and stored. After treatment with samarium is complete, 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.
                
                
                    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 ongoing clinical trials is available from the NCI website.     Targeted therapy      Targeted therapy is a treatment that uses drugs or other substances to find and attack specific cancer cells without harming normal cells. Kinase inhibitor therapy and monoclonal antibody therapy are types of targeted therapy being studied in clinical trials for osteosarcoma.     Kinase inhibitor therapy blocks a protein needed for cancer cells to divide. Sorafenib is a type of kinase inhibitor therapy being studied for the treatment of recurrent osteosarcoma.     Monoclonal antibody therapy is a cancer treatment that uses antibodies made in the laboratory, from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Denosumab, dinutuximab, and glembatumumab are monoclonal antibodies being studied for the treatment of recurrent osteosarcoma.
                
                
                    Patients may want to think about taking part in a clinical trial.
                    For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
                
                
                    Patients can enter clinical trials before, during, or after starting their cancer treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
                
                
                    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.

		                    Lung Metastasis    When osteosarcoma or malignant fibrous histiocytoma (MFH) spreads, it usually spreads to the lung. Treatment of osteosarcoma and MFH with lung metastasis may include the following:         -  Combination chemotherapy followed by surgery to remove the primary cancer and the cancer that has spread to the lung.         Bone Metastasis or Bone with Lung Metastasis    Osteosarcoma and malignant fibrous histiocytoma may spread to a distant bone and/or the lung. Treatment may include the following:         - Combination chemotherapy followed by surgery to remove the primary tumor and the cancer that has spread to other parts of the body. More chemotherapy is given after surgery.    - Surgery to remove the primary tumor followed by chemotherapy and surgery to remove cancer that has spread to other parts of the body.        Check the list of NCI-supported cancer clinical trials that are now accepting patients with metastatic osteosarcoma and metastatic childhood malignant fibrous histiocytoma of bone.
