REGIMEN 1: Patients undergo hyperfractionated TBI TID for a total of 11-12 doses on days -10 to -7 and receive thiotepa IV over 4 hours QD on days -6 and -5, fludarabine phosphate IV over 30 minutes QD on days -6 to -2, and anti-thymocyte globulin IV on days -4 to -2.

TRANSPLANTATION: Patients undergo CD34-selected allogeneic PBSCT on day 0.

To be given to patients non-malignant, life-threatening diseases and patients with hematologic malignancies, with extensive prior therapy and comorbidities who are unable to receive TBI, consists of Melphalan 70mg/m2 IV x 2 days, thiotepa 5mg/kg IV x 2 days (or 10mg/kg x 1 day), and fludarabine 25 mg/m2 IV x 5 days.

Approximately 30% of patients who are candidates for bone marrow transplants do not have an HLA-matched, or close to matched, donor available. For this reason, doctors have been testing ways to make transplants from HLA-partially matched donors as safe and effective as transplants from HLA-matched donors.

This study is being done to test the safety and the treatment results of a specific kind of transplant. In this transplant, blood from two donors will be used. Each donor will share one half of your HLA type. Blood from both donors will be transplanted at the same time.

Efficacy is measured by:

1. incidence of transplant-related mortality, overall survival and disease-free survival at 1 year post transplant.
2. incidence, tempo and complications of engraftment and hematopoietic reconstitutions and conversely, the risk of graft failure
3. incidence and severity of acute and/or chronic GVHD
4. incidence and severity of opportunistic infections developing following engraftment

The levels of engraftment and persistence of hematopoietic cells and their myeloid and lymphoid progressing from each donor post transplant. The tolerance or reactivity of engrafted T cells from each donor detected in the blood at 3, 6, and thereafter every 3-6 months until normal, post transplant against host cells and cells derived from the other parent as measured by standard mixed lymphocyte culture and cell mediated cytolysis assays.

Due to the small accrual on study, as well as patient course following treatment on study, the primary objectives of this study were not able to be analyzed.
