 RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patients immune system from rejecting the donors stem cells. When stem cells from a donor are infused into the patient they may help the patients 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 bodys normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donors T cells donor lymphocyte infusion after the transplant may help destroy any remaining cancer cells graft-versus-tumor effect.
