PURPOSE: Interleukin-10 (IL-10) is an immunoregulatory cytokine and its cervical and serum concentrations have been associated with a poor prognosis of cervical cancer. The rs1800872 polymorphism (c.-592C>A) in the promotor region of the IL-10 gene affects the production and expression of IL-10 and thus is able to determine the immune response profile in the cervix. Therefore, the aim of this work is to state the association between IL-10 c.-592C>A polymorphism and cervical cancer. METHODS: Genomic DNA was extracted from patient's peripheral blood and tumor biopsy. Socio-demographic, sexual behavior and reproductive characteristics data were collected using a questionnaire. RESULTS: Co-dominant model in logistic binary regression adjusted for confounders, showed that patients presenting with C/A genotype had 2.15 times more chances for developing cervical cancer (OR 2.15; CI95% 1.02-4.56). The dominant model, C/A + A/A, was also independently associated with 2.71 times more chances for cervical cancer development when compared to control patients (OR 2.71; CI95% 1.05-4.47). CONCLUSION: Our study analyses show the association between cervical cancer and IL-10 c.-592C>A polymorphism, demonstrating that the allele A presence was independently associated with higher risks of cervical cancer development.
