title: [Chronic myelogenous leukemia].
abstract: STI571, a BCA-ABL tyrosine kinase inhibitor, has appeared in molecular targeted therapy as a new treatment option for patients with chronic myelogenous leukemia (CML) through rational drug development. In a phase I study in the USA, adverse effects were minimal. Complete hematologic response was observed in 98% of patients with chronic phase CML treated with a daily dose of 300 mg or more, and cytogenetic response was seen in 31% of patients. STI571 has substantial activity in the blast crisis of CML and Ph + ALL. Stem cell transplantation (SCT) may be compared with interferon-alpha (IFN-alpha) therapy from three analyses reported according to risk assessment. These studies indicated that SCT increased survival only in patients who were younger and at intermediate or high risk; however, survival with SCT in older patients at higher risk was no better than with IFN-alpha therapy in a Japanese prospective study. An individualized risk assessment-based approach is useful in prioritizing SCT and IFN-alpha in patients with chronic phase CML.
