【 摘 要 】

Objective: As a proinflammatory cytokine, TNF-α is associated with increased risk of osteosarcoma (OS). Our study aimed to explore the association of TNF-α polymorphisms and OS susceptibility in the Han Chinese population. Methods: 80 OS patients and 99 healthy people, matched on the age and sex, participated in the study. Genotyping was conducted by the method of polymerase chain reaction-restricted fragment length polymorphisms (PCR-RFLP). Then logistic regression was used to evaluate the effects of TNF-α polymorphisms (-308G/A and -238G/A) on the pathology of OS. Results: The frequency of AA genotype in -308G/A locus in the cases was significantly higher than that of the healthy group (20.0% vs. 6.1%). Patients with OS were more likely to possess AA genotype of -308G/A locus (OR=4.00, 95% CI=1.41-11.38). For the patients with A allele, the risk for OS increased 0.62 fold (OR=1.62, 95% CI=1.04-2.50). There was no remarkable relationship of -238G/A polymorphisms and OS susceptibility. In addition, we found that patients with G-A and A-A haplotypes was much higher in the cases than that of control group (68.0% and 25.0%, 53.0% and 38.9%, respectively). A-G haplotype appeared to increase the risk for OS (OR=1.93, 95% CI=1.13-2.94). Conclusion: The AA genotype of -308G/A locus of TNF-α gene was a risk factor for OS, however there was no correlation between -238G/A of TNF-α and OS.
