Chronic myelogenous leukemia (CML) is a hematopoietic stem cell disorder caused by the BCRABL tyrosine kinase oncogene, which induces constitutive activation of growth and viability signaling pathways (1). CML cells are dependent on the elevated kinase activity of BCRABL, as demonstrated by the high rates of hematologic remissions induced by the ABL kinase inhibitor imatinib mesylate (Gleevec). Although complete hematologic remission rates occur in more than 95% of patients, only a minority enter a molecular remission in which BCRABL is undetectable by polymerase chain reaction. In acute phase, characterized by an increase of immature blast cells in the peripheral blood, only
