title: Role of IL-10 gene polymorphisms on the susceptibility for esophageal cancer and its association with environmental factors.
abstract: We conducted a hospital-based case-control study to investigate the association of three common SNPs (-1082G/A rs1800896, -819T/C rs1800871, and -592A/C rs1800872) of IL-10 gene polymorphisms with the susceptibility to esophageal cancer in a Chinese population. 246 patients with pathologically proven esophageal cancer and 492 healthy control subjects were collected in our study. Genotyping of IL-10-1082G/A rs1800896, -819T/C rs1800871, and -592A/C rs1800872 was performed using the Sequenom MassARRAY platform (Sequenom; San Diego, CA). Unconditional logistic regression analyses showed that subjects carrying the AA genotype and GA+AA genotype of IL-10-1082G/A rs1800896 were associated with an increased risk of esophageal cancer, and the adjusted ORs (95% CI) were 2.19 (1.31-3.64) and 1.44 (1.05-1.99), respectively. However, we did not find significant association of IL-10-819T/C rs1800871 and -592A/C rs1800872 with the development of esophageal cancer. By stratification analysis, we found that IL-10-1082G/A rs1800896 polymorphism has no significant association with smoking, drinking and family history of cancer in the first relatives in esophageal cancer risk (P>0.05). In conclusion, IL-10-1082G/A rs1800896 genetic variation may be employed as candidate biomarkers for the prediction of susceptibility in esophageal cancer.
