【 摘 要 】

Background

The aim of the present study was to evaluate the influence of tumor necrosis factor-alpha (TNF-α) −308 G > A polymorphism on hepatocellular carcinoma (HCC) risk.

Methods

The present case–control study was conducted in a Han Chinese population consisting of 753 HCC patients and 760 controls from May 2010 to March 2013. The −308 TNF-a promoter polymorphisms were detected. Conditional logistic regression was performed to analyze the association between TNF-α −308 G > A polymorphism and the risk of HCC, which were estimated by odds ratios (ORs) and their 95% confidence intervals (95% CIs).

Results

The genotypic frequencies in the cases were not similar to that of the controls, differences being statistically significant (P = 0.002). Using the GG genotype as the reference genotype, AA was significantly associated with increased risk of HCC (adjusted OR = 5.12, 95% CI = 2.31–7.82). Similarly, AG + AA genotype showed 5.59-fold increased HCC risk in a dominant model. Furthermore, we found A allele was significantly associated with increased risk of HCC, compared with G allele (OR = 4.18, 95% CI = 1.76–6.97).

Conclusion

The present study showed that TNF-α −308 G > A polymorphism was associated with increased HCC risk in a Han Chinese population. Further prospective studies on large and different ethnic populations will be necessary to confirm our findings and elucidate the underlying molecular mechanism for the development of HCC.
