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.
In conclusion, IL-10-1082G/A rs1800896 genetic variation may be employed as candidate biomarkers for the prediction of susceptibility in esophageal cancer.
