Study Arms:
- Treatment (NK cells, allogeneic stem cell transplant) (Type: EXPERIMENTAL): MYELOABLATIVE CONDITIONING REGIMEN: Patients receive high-dose melphalan IV over 30 minutes on day -7, fludarabine IV over 1 hour on days -7 to -4, undergo TBI on day -3, and NK cells IV over 30 minutes on day -2 or -1.~NON-MYELOABLATIVE CONDITIONING REGIMEN: Patients receive melphalan IV over 30 minutes on day -7, fludarabine IV over 1 hour on days -7 to -4, undergo TBI on day -3, and receive NK cells IV over 30 minutes on day -2 or -1.~TRANSPLANT: Patients undergo allogeneic PBSC or bone marrow transplant on day 0.~POST-TRANSPLANT CYCLOPHOSPHAMIDE AND GVHD PROPHYLAXIS: Patients receive cyclophosphamide IV over 3 hours on days 3 and 4, tacrolimus IV beginning on day 5 for 2 weeks and then PO for approximately 4 months, and mycophenolate mofetil PO TID beginning on day 5 for approximately 6-7 months.~NK CELLS: Patients receive NK cells IV over 30 minutes on days 7 and 28-90.
