Preparative Regimen: Patients underwent photopheresis on two consecutive days and received pentostatin 4 mg/m2/d (total dose = 8 mg/m2) by continuous IV infusion on two consecutive days following photopheresis. Total body irradiation was administered on two consecutive days following pentostatin for a total of 600 cGy given in three 200 cGy fractionated doses. Transplantation: Unmanipulated allogeneic bone marrow or G-CSF mobilized peripheral blood stem cells were infused on day 0 within 48 hours of completion of TBI. Minimum cell dose was 2 ×106 CD34 cells/kg recipient. Acute graft-vs-host-disease (GVHD) prophylaxis: Patients received Cyclosporine or Tacrolimus per institutional preference or protocol beginning no later than day -1. Methotrexate (MTX) was administered on day +1 and +3. Mycofenolate mofetil (MMF) was introduced on day 100 and could be tapered and discontinued after 12 months if no active cGVHD.
