Percentages do not always add up to 100% due to rounding.
ANLL indicates acute nonlymphocytic leukemia; NHL, non-Hodgkin lymphoma; HL, Hodgkin lymphoma; MDS, myelodysplastic syndromes; MPD, myeloproliferative disorders; Cy, cyclophosphamide; CsA, cyclosporine; and MTX, methotrexate.
Other malignancies include 121 solid (nonbreast) cancers (primarily neuroblastoma and sarcomas), 3 breast cancers, and 34 other malignancies. See Table 2 for second malignancies among these patients.
Chronic GVHD is defined as clinical extensive disease for FHCRC patients and includes all grades of chronic GVHD for CIBMTR patients.
