what research (or clinical trials) is being done for Childhood Rhabdomyosarcoma ? 
 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 website.     High-dose chemotherapy with stem cell transplant     High-dose chemotherapy with stem cell transplant is a way of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow 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.       Immunotherapy     Immunotherapy is a treatment that uses the patients immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the bodys natural defenses against cancer. This type of cancer treatment is also called biologic therapy or biotherapy.    There are different types of immunotherapy:            -  Immune checkpoint inhibitor therapy uses the body's immune system to kill cancer cells. Two types of immune checkpoint inhibitors are being studied in the treatment of childhood rhabdomyosarcoma that has come back after treatment:                  -  CTLA-4 is a protein on the surface of T cells that helps keep the bodys immune responses in check. When CTLA-4 attaches to another protein called B7 on a cancer cell, it stops the T cell from killing the cancer cell. CTLA-4 inhibitors attach to CTLA-4 and allow the T cells to kill cancer cells. Ipilimumab is a type of CTLA-4 inhibitor.       -  PD-1 is a protein on the surface of T cells that helps keep the bodys immune responses in check. When PD-1 attaches to another protein called PDL-1 on a cancer cell, it stops the T cell from killing the cancer cell. PD-1 inhibitors attach to PDL-1 and allow the T cells to kill cancer cells. Nivolumab and pembrolizumab are PD-1 inhibitors.                -  Vaccine therapy is a type of immunotherapy being studied to treat metastatic rhabdomyosarcoma.              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. There are different types of targeted therapy:            -  mTOR inhibitors stop the protein that helps cells divide and survive. Sirolimus is a type of mTOR inhibitor therapy being studied in the treatment of recurrent rhabdomyosarcoma.     -  Tyrosine kinase inhibitors are small-molecule drugs that go through the cell membrane and work inside cancer cells to block signals that cancer cells need to grow and divide. MK-1775 is a tyrosine kinase inhibitor being studied in the treatment of recurrent rhabdomyosarcoma.     -  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 in the treatment of recurrent rhabdomyosarcoma.
                
                
                    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.
