Timed-Sequential Induction in CBF-AML

Summary

Core binding factor (CBF) acute myeloid leukemias (AML) include AMLs carrying the t(8;21) translocation as well as AMLs carrying either the inversion of chromosome 16 or translocation t(16;16). CBF-AMLs are characterized by their high sensitivity to standard chemotherapeutical agents, especially to cytarabine when administered as high-dose bolus infusions, and thus by a relative good prognosis. However, relapse rates are still comprised between 30 and 50% in these patients, even if overall survival may reach approximately 65% due to the potential salvage of late relapses. The primary purpose of the protocol is to compare two modalities of timed-sequential induction in order to improve the results of the treatment of CBF-AML patients. This protocol also includes the biological characterization of the heterogeneity of these diseases (gene mutation and transcription profiles), as well as a centralized minimal residual disease monitoring and centralized evaluation of pharmacogenetic polymorphisms.
