Official Title: A Phase II Study to Evaluate the Efficacy of Posttransplant Cyclophosphamide for Prevention of Chronic Graft-versus-Host Disease After Allogeneic Peripheral Blood Stem Cell Transplantation
Brief Summary: This phase II trial studies how well cyclophosphamide works in preventing chronic graft-versus-host disease after allogeneic peripheral blood stem cell transplant in patients with hematological malignancies. Giving chemotherapy and total-body irradiation before transplantation helps stop the growth of cancer cells and prevents the patient's immune system from rejecting the donor's stem cells. Healthy stem cells from a donor that are infused into the patient help the patient's bone marrow make blood cells; red blood cells, white blood cells, and platelets. Sometimes, however, the transplanted donor cells can cause an immune response against the body's normal cells, which is called graft-versus-host disease (GVHD). Giving cyclophosphamide after transplant may prevent this from happening or may make chronic GVHD less severe.
