A significant association of CxCa with various polymorphisms was observed: rs1800797 in the IL-6 gene (odds ratio [OR] = 0.88, 95% confidence intervals [CI]: 0.79-0.99); rs1041981 in the LTA gene (OR = 0.87, 95% CI: 0.78-0.98), and rs9344 in the CCND1 gene (OR = 1.14, 95% CI: 1.02-1.27), for those individuals carrying the rare allele.
The rare allele (A) of SNP rs2239704 in the 5' UTR of the LTA gene was significantly associated with increased risks of cervical cancer (OR=1.31, 95% CI: 1.15-1.50; adjusted p-value: 0.013) and vulvar cancer (OR=1.51, 95% CI: 1.30-1.75; adjusted p-value: 1.9 × 10(-5) ).
