ABCB1 polymorphism and susceptibility to acute lymphoblastic leukemia: a meta analysis.

ABSTRACT:

Background

A large body of studies has investigated the potential role of ABCB1 polymorphism in ALL susceptibility. However, the results are conflicting. The aim of the present meta-analysis was to define the effect of ABCB1 polymorphism on ALL risk.

Methods

We identified 8 eligible studies involving 1,308 cases and 1,427 controls through searching PubMed and Enbase databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to access the strength of the association with both fixed effects and random effect models.

Results

We found ABCB1 polymorphism was associated with an increased risk of ALL under the homozygote genotypes (TT vs. CC: OR, 1.29, 95% CI, 1.08-1.54), the recessive model (TT vs. CT + CC: OR, 1.47, 95% CI, 1.02-2.13) and the allele model (
