Objective: To evaluate the relationship between five single nucleotide polymorphism loci in the MGMT, XPA, XPD and XPG genes and the prevalence of non-Hodgkin's lymphoma.
Methods: A case-control study of 73 lymphoma cases and 500 healthy controls was conducted and the Mass-ARRAY method was applied for detection of MGMT L84F, MGMT K178R, XPA TSS+62, XPD K751Q and XPG TSS+372.
Results: MGMT L84F (T allele) was associated with an increased risk of non-Hodgkin lymphoma (OR=2.085, 95%CI=1.069-4.068, P=0.029), mainly in B-cell lymphoma, of which the risk increased by 2.403-fold (OR=2.403, 95%CI=1.103-5.235, P=0.024). No statistically significance was found for MGMT K178R, XPA TSS+62, XPD K751Q and XPG TSS+372.
Conclusion: Single nucleotide polymorphism in the MGMT gene may closely related to the occurrence of non-Hodgkin lymphoma, especially of B-cell subtype.
