what research (or clinical trials) is being done for Osteosarcoma and Malignant Fibrous Histiocytoma of Bone ? 
 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.
