The effects of air pollution on mortality and clinicopathological features of esophageal cancer.

ABSTRACT: This study aimed to estimate the associations between air pollution and esophageal cancer. In the ecologic cross-sectional study, correlation analyses were made between city-level mean concentrations of particulate matter less than 10μm in aerodynamic diameter (PM₁₀), SO₂, NO₂ and city-level age-standardized mortality rates of esophageal cancer in Shandong Province, China. PM₁₀ (p=0.046) and NO₂ (p=0.03) both had significant linear correlations with esophageal cancer mortality rates. After introducing smoking as a risk factor in models of multiple linear regression analyses, PM₁₀ was still an independent risk factor that increased esophageal cancer mortality rates. This study further compared clinicopathologica
