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 conducted a hospital based case-control study to evaluate the genetic effects of functional single nucleotide polymorphisms (SNPs): interleukin 9 (IL9) rs31563 C>T, IL9 rs31564 G>T, IL10 rs1800872 T>G, IL12A rs2243115 T>G, IL12B rs3212227 T>G and IL13 rs1800925 C>T on the development of esophageal cancer.
