The relationship between decaffeinated coffee consumption and pancreatic cancer was examined using data from a hospital-based case-control study of individuals aged 20–80 years in 18 hospitals in 6 United States cities, from January 1981 to December 1984. Among the males, 127 cases and 371 controls were examined, while for females, the figures were 111 and 325 for cases and controls, respectively. Decaffeinated coffee use was not associated with an increased risk of pancreatic cancer in males (odds ratio = 0.7 for 3 or more cups/day; 95% confidence interval = 0.4–1.4). For females, an elevated risk was seen for drinkers of 1–2 cups/day (odds ratio = 1.6; 95% confidence interval = 1.0–2.7), but this finding was of borderline significance and elevation in risk was not found for drinkers of 3 or more cups/day (odds ratio = 0.9; 95% confidence interval = 0.4–1.9). Cigarette smoking was significantly associated with pancreatic cancer in both males and females. Factors examined and not found to be related to pancreatic cancer included education, occupation, religion, marital status, alcohol drinking, saccharin use, height, weight 5 years before hospitalization, history of previous diseases, and residence.
