This phase II trial studies how well giving fludarabine phosphate and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer. Giving chemotherapy drugs, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells and prepares the patient's bone marrow for the 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 cyclosporine and mycophenolate mofetil may stop this from happening.

PRIMARY OBJECTIVES:
I. To determine the one year survival of patients undergoing umbilical cord blood transplantation (UCBT) after a myeloablative preparative regimen consisting of cyclophosphamide (CY), fludarabine (FLU) and fractionated total body irradiation (TBI).
SECONDARY OBJECTIVES:
I. Determine the incidence of transplant-related mortality (TRM) at 6 months after UCBT.
II. Evaluate pattern of chimerism after double UCBT.
III. Determine incidence of neutrophil engraftment at day 42 after UCBT.
IV. Determine the incidence of platelet engraftment at 1 year after UCBT.
V. Determine the incidence of acute graft-versus-host disease (GVHD) grade II-IV and grade III-IV at day 100 after UCBT.
VI. Determine the incidence of chronic GVHD at 1 year after UCBT.
VII. Determine the disease free survival at 1 and 2 years after UCBT.
VIII. Determine the incidence relapse at 1 and 2 years after UCBT.
OUTLINE:
Patients receive a conditioning regimen comprising fludarabine phosphate intravenously (IV) over 1 hour on days -8 to -6, and cyclophosphamide IV over 1 hour on days -7 and -6. Patients also undergo TBI twice daily on days -4 to -1. Patients then undergo 1 or 2 units of UCBT on day 0. Patients receive filgrastim IV once daily beginning on day 1 and continuing until blood counts recover.
Patients receive GVHD prophylaxis comprising cyclosporine IV over 2 hours 2 or 3 times daily beginning on day -3 and continuing until day 100 followed by a taper until day 180. Patients also receive mycophenolate mofetil IV or orally (PO) 2 or 3 times a day beginning on day -3 and continuing until day 30 or 7 days after engraftment in the absence of acute GVHD.
After completion of study treatment, patients are followed up periodically for 2 years.
