title: Optimal first-line treatment of chronic myeloid leukemia. How to use imatinib and what role for newer drugs?
abstract: The development of imatinib mesylate (Gleevec), a tyrosine kinase inhibitor targeted against the causative Bcr-Abl protein in chronic myeloid leukemia (CML), has resulted in hematologic and cytogenetic remissions in all phases of CML. Following imatinib treatment, more than 90% of patients obtain complete hematologic response, and 70% to 80% achieve a complete cytogenetic response. With 5 years of follow-up, the data are very encouraging, exhibiting a major change in the natural history of the disease. The understanding of at least some of the mechanisms of resistance to imatinib has led to a rapid development of new agents that may overcome this resistance. Combination strategies are currently being investigated in preliminary clinical studies and may prove to be useful. Overall, there are an increasing number of treatment options now available for patients with CML.
