文摘

A DNA repair protein, X-ray repair cross-complementing group 1 (XRCC1), has been implicated in the development of multiple cancers, including non-Hodgkin lymphoma (NHL). Recent studies evaluating the association between XRCC1 polymorphisms and NHL risk have been published. However, the published studies are controversial. This systematic review and meta-analysis of case–control studies aimed to evaluate the association between three single nucleotide polymorphisms (SNPs) of XRCC1, Arg194Trp, Arg280His and Arg399Gln, with risk for developing NHL.

We conducted a comprehensive literature search using PubMed, Embase, and the Cochrane Library databases for relevant studies regarding the association between XRCC1 SNPs and NHL risk.

Thirteen published case–control studies involving the Arg194Trp (3897 cases and 5371 controls), Arg280His (2140 cases and 3158 controls) and Arg399Gln (2722 cases and 4856 controls) SNPs were selected for meta-analysis. The Arg194Trp SNP was associated with increased NHL risk within the Asian population, and increased diffuse large B cell lymphoma (DLBCL) risk within the overall population under dominant model. The Arg399Gln SNP was associated with decreased risk for NHL and DLBCL under heterozygous and dominant models of inheritance. The Arg280His SNP was not associated with NHL risk by overall or subgroup analyses.
