AML indicates acute myelogenous leukemia; CML, chronic myelogenous leukemia; ALL, acute lymphoblastic leukemia; MDS, myelodysplastic syndrome; CIBMTR, Center for International Blood and Marrow Transplant Research; TBI, total body irradiation; Cy, cyclophosphamide; Bu, busulfan; CMV, cytomegalovirus; GVHD, graft-versus-host disease; CSA, cyclosporine; MTX, methotrexate.
Disease status is categorized as follows:
Early = AML/ALL (CR1), CML (CP1), MDS (RA/RARS/pre-HCT marrow blasts <5%);
Intermediate = AML/ALL (≥CR2), CML (AP or ≥CP2);
Advanced = AML/ALL (REL/PIF), CML in BP, MDS (RAEB/RAEB-t/CMML or marrow blasts ≥5%);
Other/unknown = everything else.
