Bone marrow aspiration and/or biopsy were performed 3-5 weeks after transplant to assess donor-cell engraftment. Primary Graft Failure was defined as a neutrophil count below 500/μL or the absence of donor-derived hematopoiesis (\\<5%donor cells) before relapse, death, or re-transplantation. Secondary Graft Failure was defined as the achievement of primary engraftment and a subsequent decrease in neutrophils to 3 consecutive counts of less than 100/μL or the absence of donor-derived hematopoiesis (\\<5% donor cells) before relapse, death, or re-transplantation.","groups":[{"description":"Non-myeloablative Stem Cell Transplant (SCT): Donor will receive Granulocyte colony-stimulating factor (G-CSF) 8 mcg/kg/d subcutaneously twice daily for 4 days, until pheresis is completed or until white blood cells \\> 100,000.
