The high-risk group includes patients with CML who had a donor with disparity for multiple class I alleles. All other patients are categorized in the low-risk group. Results for marrow transplantation without T-cell depletion in patients with CML have been reported previously.10 Graft failure in controls was defined according to published criteria.21 All patients were prepared for transplantation with a conditioning regimen of cyclophosphamide and 12.0 to 15.75 Gy TBI and received methotrexate plus cyclosporine for GVHD prophylaxis.
