Small intestine cancer is relatively rare. Clinical reports have suggested that several medical conditions may predispose to increased occurrence of this cancer, but otherwise its etiology is unknown. In one of the first case-control studies of this cancer, we compared questionnaire responses provided by next-of-kin of 430 persons who died of small intestine cancer cf921 controls who died of other causes. Subjects were identified from decedents included in the 1986 United States National Mortality Followback Survey. The questionnaires sought information on demographic and lifestyle characteristics, including diet and use of tobacco and alcohol. Tobacco and alcohol consumption were unrelated to risk of small intestine cancer, but weekly or more frequent consumption of red meat and monthly or more frequent intake of salt-cured/smoked foods were associated with two- to three fold increases in risk. The findings suggest that dietary factors probably are involved in risk of small intestine cancer, but additional research in other settings is required to clarify the determinants of these rare cancers.
