title: Graft-versus-host disease after treatment for chronic granulocytic leukaemia in transformation.
abstract: Two patients with chronic granulocytic leukaemia in blast cell transformation treated with high-dose cytotoxic drugs and transfusion of cryopreserved chronic phase buffy coat stem cells developed a clinical and pathological syndrome that closely resembled graft-versus-host disease (GVHD). It was possible (1) that both patients had true GVHD resulting from transfusion of HLA-identical blood products, or (2) that both cases were examples of the 'pseudo-GVHD' seen by others following syngeneic transplants. The laboratory findings did not support one postulated pathogenetic mechanism for 'pseudo-GVHD'--namely a lack of suppressor T-lymphocytes.
