Background:
Gallbladder carcinoma (GBC) is a highly aggressive neoplasm that arises in the background of gall stones and inflammation. Anti-inflammatory cytokine interleukin-10 (IL-10) gene polymorphisms have been associated with susceptibility to various inflammatory diseases and cancers.
Aim:
of the study The aim of the present study was to investigate whether IL-10-819C/T polymorphism is associated with GBC susceptibility.
Methods:
The study subjects comprised 124 GBC patients, 135 patients with symptomatic gallstone disease, and 200 healthy subjects. Genomic DNA was extracted from blood leukocytes and IL-10-819C/T gene polymorphism was analyzed by polymerase chain reaction-restriction fragment length polymorphism.
Results:
Frequency distributions of IL-10-819C/T genotypes were similar in GBC, gallstone patients, and healthy subjects. However, after stratification on the basis of sex, in male GBC patients, the TT genotype of IL-10-819C/T polymorphism showed an approximately sevenfold risk (p value = 0.038; odds ratio = 6.58; 95% confidence interval = 1.11-39.11) in the presence of gall stones when compared with gallstone patients.
Conclusion:
These results suggest that interplay of sex hormones and IL-10-819C/T polymorphism may lead to the susceptibility of gallstone-mediated gallbladder carcinogenesis.
