Identification of BCR-ABL as the defining leukemogenic event in chronic myeloid leukemia (CML) revolutionized the understanding of the molecular pathogenesis of this disease. Imatinib has been designed as a potent selective BCR-ABL inhibitor, and is now considered the standard of care for the first-line therapy of patients with chronic phase CML based on its high long-term response rates and favorable tolerability profile compared with previous standard approaches. However, resistance to imatinib develops in 2–4% of patients annually. Attempts have been made to improve first-line therapy by increasing imatinib doses or combining imatinib with other drugs in selected cohorts, either in patients with a high risk or in the total population. As an alternative option, treatment escalation according to response at defined milestones has been proposed. Allogeneic stem cell transplantation remains an alternative for eligible patients after failure with imatinib or second-generation tyrosine kinase inhibitors. Despite improvement of transplant-related morbidity and mortality during the last decade, front-line transplantation is not recommended for most patients.
