Epidemiology of gastrointestinal cancer.
Environ Health Perspect 1974 Dec; 9:299-305
Evidence suggests that the etiology of gastrointestinal cancer is one of multiple factors. The synergistic effect of exposure to asbestos (1332214) and cigarette smoking in the production of bronchogenic carcinoma is demonstrated by data on cohorts of insulation workers. A modest increase in the number of deaths from gastrointestinal cancer is also found in asbestos workers, but smoking does not seem to act in synergistic fashion at that site, except perhaps in the esophagus. Deaths from cancer occurred almost entirely after a period of 20 years or more from initial exposure.
