Summary
Brief summary (as posted)
RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell and donor natural killer cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain 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. Removing the T cells from the donor cells before transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving a donor peripheral stem cell transplant and a donor natural killer cell transplant after total-body irradiation, thiotepa, fludarabine, and muromonab-CD3 works in treating patients with leukemia or other blood diseases.
