T Cell-Reduced Unrelated Donor Allogeneic Peripheral Blood Stem Cell Transplantation With Pentostatin and Low-Dose Total Body Irradiation

0164-07-FB

RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant and giving cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects of giving a donor stem cell transplant after pentostatin and total-body irradiation and to see how well it works in treating patients with hematological cancer.
