Abstract

All 2583 residents of Rochester, Minnesota, who had gallstones initially diagnosed during the years 1950 to 1970 were followed for the development of gastrointestinal malignancies. Although 69 members of the cohort subsequently developed 72 gastrointestinal malignancies, this number of cases did not exceed the 76 cases expected (relative risk, 1.0). The risk for gallbladder cancer was increased threefold, but the increase was significant only in men (p = 0.05; 95% confidence interval, 1.0 to 30.0). The absolute incidence and the total number of men and women who developed gallbladder cancer was low (n = 5). The actual incidence of other gastrointestinal malignancies in our cohort with gallstones did not exceed the expected incidence in the general population of Rochester, Minnesota, Specifically, the risk for colon cancer was not increased, even after cholecystectomy. These data support an association between cholelithiasis and gallbladder cancer. We found, however, no association betweeen cholelithiasis or cholecystectomy and any other gastrointestinal malignancy.
