Chemotherapy and granulocyte colony stimulating factor-mobilized blood cell infusion followed by interferon-α for relapsed malignancy after allogeneic bone marrow transplantation

Abstract

Background: Interferon-α (IFN) is known to promote graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation (allo BMT). This property may also be used to enhance a graft-versus-leukaemia effect (GVL) after donor leucocyte infusion (DLI), a mode of therapy increasingly offered to patients relapsing after allo BMT. Aim: The aims of the present study were to examine the efficacy and toxicity of IFN therapy administered after granulocyte colony-stimulating factor (G-CSF)-stimulated blood cells given as DLI in patients with acute myeloid leukaemia (AML), chronic myeloid leukaemia (CML), acute lymphoblastic leukaemia (ALL), acute undifferentiated leukaemia (AUL) and multiple m..
