title: CCL2 -2518 A/G single nucleotide polymorphism as a risk factor for breast cancer.
abstract: The contribution of the CCL2 -2518 A>G (rs 1024611) polymorphism in the occurrence and progression of various cancers has been found to be discordant. We studied the prevalence of the CCL2 -2518 A>G polymorphism in patients with breast cancer (n = 160) and controls (n = 323) in a sample of the Polish population. There were no significant differences in CCL2 -2518 A>G genotypes between patients with breast tumors and controls. Odds ratio (OR) for patients bearing the GG genotype was 1.481 (95% CI = 0.7711-2.845, P = 0.2358), and OR of the GG and AG genotypes was 0.7269 (95% CI = 0.4967-1.064, P = 0.1002). There was also no significant distinction in the prevalence of alleles between patients and healthy individuals. OR for the CCL2 -2518 G allele frequency was 0.8903 (95% CI = 0.6611-1.199, P = 0.4441). Analysis of the association between tumor size, lymph node metastases, histological grade, and distribution of genotypes and alleles for the CCL2 -2518 A>G polymorphism also did not show significant differences. Our results did not show association of the CCL2 -2518 A>G polymorphism with breast cancer occurrence and clinical characteristics in a sample of the Polish cohort.
