Cytogenetic Characteristics of Childhood Acute Lymphoblastic Leukemia:A Study of 1541 Chinese Patients Newly Diagnosed between 2001 and 2014

摘要

Objective:Cytogenetic abnormalities have been proven to be the most valuable parameter for risk stratification of childhood acute lymphoblastic leukemia(ALL).However,studies on the prevalence of cytogenetic abnormalities and their correlation to clinical features in Chinese pediatric patients are limited,especially large-scale studies.Methods:We collected the cytogenetics and clinical data of 1541 children newly diagnosed with ALL between 2001 and 2014 in four Chinese hospitals,and retrospectively analyzed their clinical features,prognosis and risk factors associated with pediatric ALL.
