PURPOSE: Polymorphisms in the receptor for advanced glycation end products (RAGE) gene may influence the risk of cancer, but the results are inconsistent. Therefore, we performed a systematic review to identify statistical evidence of the association between the 3 polymorphisms rs2070600 G/S (82G>S), rs1800624 T/A ( -374 T>A) and rs1800625C/T (-429 C>T) and the risk of cancer. METHODS: We searched PubMed database (http://www.ncbi. nlm.nih.gov/pubmed/), EMBASE database (http://www.elsevier.com/online-tools/embase ) and China National Knowledge Infrastructure (CNKI) database (http://www.cnki.net/) until Aug 30, 2014 to identify eligible studies. RESULTS: The pooled analysis revealed positive association between RAGE rs2070600 polymorphism and cancer risk in all genetic models (homozygous: OR=1.831, 95%CI: 1.548-2.166, p<0.001, allele: OR=1.321, 95%CI: 1.164-1.499, p<0.001, heterozygous: OR=1.42, 95%CI:1.126-1.792, p=0.003, dominant: OR=1.499, 95%CI: 1.200-1.874 ; p<0.001, recessive: OR=1.376, 95%CI: 1.197-1.583, p<0.001). We failed to get an effective conclusion about the association between the rs1800624 and rs1800625 polymorphisms and cancer risk in overall comparison. But in subgroup analysis, the rs1800624 polymorphism significantly increased lung cancer susceptibility in the homozygous model (OR=1.486, 95%CI:1.147-1.924, p=0.003) and the allele model (OR=1.15, 95%CI:1.029-1.285, p=0.014), but most likely contributed to decreased susceptibility to breast cancer in the allele model (OR=0.791 95%CI: 0.648-0.965, p=0.021), the heterozygous model (OR=0.733, 95%CI:0.577-0.931, p=0.011) and the dominant model (OR=0.741, 95%CI:0.588-0.934, p=0.011). No significant association was found between RAGE rs1088625 polymorphism and cancer risk in Caucasians, but these results should be interpreted with caution. CONCLUSION: The polymorphism of rs2070600 in the RAGE gene may increase the susceptibility to several human cancers, especially to lung cancer and to Asians. The rs1800264 most likely contributes to decreased susceptibility to breast cancer but increased susceptibility to lung cancer. However, large-scale studies involving various cancer types and different populations are needed for a precise conclusion.
