Associations between Single Nucleotide Polymorphisms from the Genes of Chemokines and the CXCR2 Chemokine Receptor and an Increased Risk of Endometrial Cancer.

Significant relationships with endometrial cancer were demonstrated, both for , , and chemokines and for the chemokine receptor . The reported case-control study of genetic associations was designed to establish the role of selected single nucleotide polymorphisms (SNPs) of the , , , and genes in the onset and progression of endometrial cancer. This study was conducted on 282 women, including 132 (46.8%) patients with endometrial cancer and 150 (53.2%) non-cancerous controls. The genotypes for rs4586, rs2107538 and rs2280789, rs2227532 and -738 T>A, and rs1126580 were determined, using PCR-RFLP assays. The AA homozygotes in rs2107538 were associated with more than a quadruple risk of endometrial cancer ( ≤ 0.050). The GA heterozygotes in the SNP were associated with approximately threefold higher cancer risk ( ≤ 0.001). That association also remained significant after certain adjustments, carried out for age, diabetes mellitus, arterial hypertension, or endometrial thickness above 5 mm ( ≤ 0.050). The A-A haplotypes for the polymorphisms and T-A-A haplotypes for the and SNPs were associated with about a twofold risk of endometrial cancer ( ≤ 0.050). In conclusion, rs4586, rs2107538 and rs2280789, and rs1126580 demonstrated significant associations with an increased risk of endometrial cancer.
