Abstract

This study aims to explore whether certain occupations were associated with the risk of esophageal squamous cell carcinoma (ESCC) in Taiwan. In a hospital-based case-control study, we collected 326 newly diagnosed ESCC patients and 386 age-matched controls (the ratio of case patients: controls = 1:1–2). All respondents completed a questionnaire, including 33 occupations in which environments potential exposure to cancer-related hazards are present. Workers with dust and metal exposure were categorized into Groups A and B, respectively. Relative risks for ESCC were estimated by odds ratios adjusting for covariates (AOR). Compared with the controls, farmer/gardener (AOR = 2.08, 95% CI = 1.02–4.24) and workers in Group A (AOR = 2.80, 95% CI = 1.21–6.47) had significantly higher risk for developing ESCC. A tendency of increased risk was also found in workers in group B (OR = 5.72 95% CI = 2.33–14.03), but such association was not significant after adjusting for other covariates (AOR = 1.57, 95% CI = 0.54–6.61). Our results suggested that farmer/gardener and workers with exposure to dust had a significant excess risk of ESCC. This study added further evidence to the current knowledge that occupational hazards are important in the development of ESCC.
