Abstract
Human leukocyte antigen (HLA) genetic polymorphisms are assumed to be correlated to the risk of chronic myelogenous leukemia (CML) in various ethnicities. Up to now, no clear consensus has been reached. Our goal is to address this issue in Chinese population. By searching the data in PubMed, Embase and four Chinese databases (prior to July 2010), the association of HLA genetic polymorphisms with CML has been fixed as the research objective. We studied a totality of 12 studies, comprising 2281 CML cases and 41000 health controls. The data demonstrated that HLA-A*11, A*74, HLA-B*40, B*47, B*55 and B*81 alleles were correlated with the increasing risk of CML. Nevertheless, HLA-DRB1*13 allele seemed to contribute to the genetic protection to CML. Conclusively we suggested that certain HLA alleles might be in association with the pathogenesis of CML in Chinese population. Due to little statistical scale, larger studies and particularly in a mono-people background, our hypothesis need to be further investigated in the future.
