 The fusion transcript AML1/ETO corresponding to translocation t(8;21)(q22;q22) can be found in approximately 7-12% of childhood de novo AML.     ///    "Three of the relapsed children showed, prior to relapse, an increase of the AML1/ETO fusion transcript at 6, 9, and 11 weeks, respectively. "    ///    Monitoring of minimal residual disease (MRD) by real-time quantitative reverse transcription PCR (RQ-RT-PCR) in childhood acute myeloid leukemia with AML1/ETO rearrangement..     ///    "Therefore, we analyzed the follow-up of 15 AML1/ETO-positive children using real-time quantitative reverse transcription PCR (RQ-RT-PCR), all enrolled in the multicenter therapy trial AML-BFM 98. "    ///    "At diagnosis, a median of 10 789 copies AML1/ETO was found. "    ///    AML1/ETO copy numbers were normalized to the control gene ABL and the results were expressed in copy numbers AML1/ETO per 10 000 copies ABL.
