MORTALITY FROM GASTRIC CARDIA AND LOWER ESOPHAGUS CANCER AND OCCUPATION

The incidence of adenocarcinoma of the gastric cardia and esophagus is increasing steadily in the United States. Little is known about the e tiology of these cancers. We used occupation and industry information on the death certificates from 24 states (1984 to 1989) to conduct a c ase-control analysis of gastric cardia and gastric cardia/lower esopha gus cancer. Risks were also calculated for other gastric cancers combi ned. Controls were deaths from other causes except cancer and gastroin testinal disorders. Increased risks of gastric cardia and cardia/lower esophagus among white women were found for administrative jobs (cardi a odds ratio (OR) = 3.9; 95% confidence interval (CI), 1.5-9.8) and he alth professionals (cardia OR = 1.8; 95% CI, 0.6-5.3). Occupations ass ociated with a lower socioeconomic status showed no significant excess risks. A similar pattern in risks was seen for men.
