The risk of gastric cardia cancer was evaluated by occupation and industry using death certificate data for 24 US states. Among white men, occupations with elevated risk included financial managers, janitors and cleaners, production inspectors and truck drivers. Industries with elevated risk included pulp and paper mills, newspaper publishing and printing, industrial and miscellaneous chemicals, water supply and irrigation. A consistent pattern of risk increase by level and probability of exposure was observed only for sulfuric acid mists. A significant increase in risk was observed for subjects exposed to lead, although crosstabulation of gastric cardia cancer risk by probability and level of exposure did not show consistent trends. Asbestos exposure showed an overall 50% increase but no consistent trends among white men. None of the 12 occupational hazards showed an association with risk for black men.
