title: Occupational risk factors for gastric cancer in Shanghai, China.
abstract: Occupational data for over 13,000 incident stomach cancer cases reported to the Shanghai Cancer Registry between 1980 and 1984 were compared with 1982 census employment information to calculate standardized incidence ratios for stomach cancer in the Shanghai urban area. Several occupations were found to have statistically significantly increased risks for stomach cancer, most notably grain farming and several jobs involving potential for exposure to metal, wood, and other dusts and to fossil fuel combustion products. Because of the large numbers involved and consistency of associations, the findings raise hypotheses regarding occupational exposures that warrant further investigation.
