Abstract
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.
