Key Words: Pediatric acute myeloid leukemia , AML1/ETO fusion gene , RT-PCR , Clinical outcome , Prognostic significance..     ///    The aim of this work is to study the frequency of AML1/ETO fusion gene in a series of Egyptian childhood AML cases.     ///    "In conclusion, we report a frequency of 19.2% of AML1/ETO fusion gene in our newly diagnosed pediatric AML cases. "    ///    AML1/ETO Fusion Gene in de novo Pediatric Acute Myeloid Leukemia: Clinical Significance and Prognostic Implications..     ///    "On comparing the AML1/ETO fusion gene status with overall survival, no significant difference was found between AML1/ETO positive and negative cases. "    ///    AML1/ ETO fusion transcript was detected by the reverse transcriptase- polymerase chain reaction (RT-PCR) technique.     ///    The AML1/ETO fusion transcript was detected by a singleround RT-PCR reaction and was found to be expressed in 15 out of 78 cases (19.2%).     ///    "AML1/ETO positive patients were 7 girls and 8 boys, with ages ranging from 5 to 15 years.
