About this study

This early phase I trial studies the side effects and feasibility of total body irradiation using intensity modulation radiation therapy (IMRT) when given in combination with cyclophosphamide prior to stem cell transplant to treat severe systemic sclerosis. IMRT delivers total body radiation therapy more precisely and may reduce radiation exposure to sensitive normal organs. Giving chemotherapy, such as cyclophosphamide, and total body irradiation before a donor stem cell transplant helps kill cancer cells in the body and helps make room in the bone marrow for new blood-forming cells (stem cells) to grow. Giving IMRT and cyclophosphamide prior to stem cell transplant may work better in treating severe systemic sclerosis and reduce radiation doses to lung and kidneys compared to cyclophosphamide alone.
