Abstract Objective:To investigate the clinical characteristics,treatment responsiveness and prognostic factors of childhood acute myelogenous leukemia.Methods:Two hundred and seventy-four children with acute myelogenous leukemia diagnosed between 1978 and 1995 were retrospectively analyzed.Results and conclusions:Male∶female is 1.6∶1.The median age was 7.25 years. M2 and M3 were the commonest subtypes( 80%).Twenty cases were hyperleukocytosis and 24 with extramedullary involvement.Thirty two percent of the patients was Auer rods positive.Two hundred and forty-four patients received combination chemotherapy.Complete remission(CR) rates varied from 55.88% to 92.31%.Intensive chemotherapy(including DA,DA+Vm26 or Vp16) was the cornerstone for high CR rate.Other factors influencing CR rate were initial WBC count and hepatosplenomegaly.
