This study demonstrates that elevated human exposure to BPA and BPS may be associated with the increased lung cancer risk.
Elevated urinary bisphenol A (BPA) concentrations have been associated with lung cancer in humans. However, toxicological studies demonstrated that the proliferation of lung cancer cells was inhibited by BPA exposure. Therefore, it is still necessary to determine whether exposure to BPA and other bisphenol analogues (BPs) is associated with lung cancer in humans. In this study, 226 lung cancer patients and 243 controls were randomly recruited. Concentrations of three BPs in human urine were quantified and their relationships with the risk of human lung cancer were evaluated. BPA (mean 1.03 ng/mL, 0.87 mu g/g Cre) was the predominant BP in human urine, followed by bisphenol S (BPS) (0.72 ng/mL, 0.53 mu g/g Cre) and bisphenol F (0.32 ng/mL, 0.37 mu g/g Cre). Significant correlations between creatinine-corrected urinary BPA concentrations and the lung cancer risk (odds ratio (OR) (adjusted) = 1.28, 95% confidence interval (CI): 1.17, 1.40; P-trend = 0.04) were found using logistical regression analysis. Creatinine-corrected urinary concentrations of BPS in participants showed significant correlations with lung cancer (ORadjusted = 1.23, 95% CI: 1.04, 1.59; P-trend = 0.01) in the adjusted model. In the stratification analysis, the significant correlation between urinary creatinine-corrected concentrations of BPA and the risk of lung cancer still observed in male participants (OR = 1.36, 95% CI: 1.09, 1.62, p = 0.040). This study demonstrates that elevated human exposure to BPA and BPS may be associated with the increased lung cancer risk.
