In patients with t(8;21) positive AML no consensus exists over the disappearance of the AML1/ETO fusion transcript during the course of disease and most studies reported reverse transcriptase polymerase chain reaction (RT-PCR) positivity as a common finding after consolidation chemotherapy, autologous and allogeneic stem cell transplantation (alloSCT).     ///    Due to the slow kinetics of AML1/ETO after consolidation chemotherapy the value of qualitative RT-PCR to predict early relapse is limited.
