Objective To study the clinical and laboratory characteristics and treatments in children with chronic myelogenous leukemia （CML）. Methods Respective analyze of the clinical and laboratory data of twelve pediatric patients with CML from December 1994 to October 2009 was performed. Results The disease predominately affected children from 5 to 9 years old （50 % of the patients）, with a higher prevalence in boys than girls （gender ratio： 5：1）. The duration before the diagnosis was different from three days to one year. The main presenting symptoms were fever, bleeding,asthenia, and complaints related to splenomegaly.Some cases were diagnosed incidentally. Markedly raised leukocyte and platelet counts were common.Conclusion CML in children is rare, and average level of WBC count seems to be much higher than adult.
