Prognostic value of minimal residual disease quantification by real-time reverse transcriptase polymerase chain reaction in patients with core binding factor leukemias.

Purpose: In patients with acute myeloblastic leukemia with t(8;21) or inv(16) aberrations (core binding factor [CBF] leukemias), minimal residual disease (MRD) can be sensitively detected during and after chemotherapy by use of molecular methods. However, the prognostic impact of qualitative MRD detection is still under debate. In this study, the prognostic value of MRD quantification in patients with CBF leukemias was assessed.
