Our results revealed that IL-10 rs1800872 T>G and rs1800896 A>G polymorphisms has a significantly association with the increased risk of esophageal cancer under the allele and dominant models; rs1800871 T>G, rs1800872 T>G and rs1800896 A>G under allele and dominant models could increase the risk of nasopharyngeal cancer; rs1800871T>G, rs1800872T>G and rs1800896 A>G SNPs under allele model were closely related to the susceptibility to oral cancer.

We determined whether single nucleotide polymorphisms (SNPs) at positions -1082 A/G (rs1800870), -819 T/C (rs1800871) and -592 A/C (rs1800872) in the IL-10 gene promoter were involved in predisposing an individual to oral cancer.
