Summary
Brief summary (as posted)
RATIONALE: Giving chemotherapy drugs, such as fludarabine phosphate and melphalan, and HT before a donor stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving HT together with fludarabine phosphate and melphalan before a transplant may stop this from happening. PURPOSE: This clinical trial studies helical tomotherapy (HT), fludarabine phosphate, and melphalan followed by donor stem cell transplant in treating patients with hematologic malignancies.
