Rationalizing Autotransplant Strategies for Chronic Myeloid Leukemia

Abstract

The molecular genetic basis of chronic myeloid leukemia (CML) is well-defined, but until recently therapeutic approaches have been largely empiric. Conventional chemotherapy and interferon offer palliation, but only bone marrow transplantation provides for cure. Because the majority of CML patients are not candidates for allogeneic transplantation, autologous strategies have emerged as an alternative. Data from murine models of CML provide insights into the mechanisms by which autotransplant might be effective in the treatment of CML. Further dissection of the molecular pathways by which the BCR/ABL protein can induce leukemia offers the promise of a more targeted, rationally-designed therapy. When used for remission maintenance therapy following autologous bone marrow transplantation, specific inhibitors of BCR/ABL should provide for long term disease-free survival.
