Abstract

The aim of the present study is to investigate the combined effects of urinary total arsenic level, cigarette smoking and secondhand smoke on Urothelial Carcinoma (UC) risk. We conducted a hospital-based case-control study consisting of 584 UC cases and 1098 cancer-free controls and found that ever smokers who exposed to secondhand smoke and carried the G/A and A/A genotypes of the TNF-α -308 G/A polymorphism had a significantly higher UC risk (OR = 5.17, 95% CI = 2.26–11.86). Ever smokers who exposed to higher total arsenic level (≥ 16.38 μg/g creatinine) and secondhand smoke had a significantly increased UC risk (OR = 13.18, 95% CI = 6.48–26.83). In conclusion, our findings suggest that the joint effects of urinary total arsenic level, cigarette smoking, secondhand smoke and the TNF-α -308 G/A and A/A genotypes on UC risk were statistically significant and showed a dose-response relationship.
