Coffee consumption and risk of gastric and pancreatic cancer—A prospective cohort study
Menée en Finlande sur 60 041 hommes et femmes (âge : 26 à 74 ans ; durée moyenne de suivi : 18 ans), cette étude prospective évalue l'association entre la consommation de café et le risque de cancer de l'estomac (299 cas) ou du pancréas (235 cas) en fonction du sexe et de la consommation quotidienne de café
Only few prospective studies have examined the association between coffee consumption and risk of gastric and pancreatic cancer. This study is designed to evaluate this relationship among Finns, whose coffee consumption is the highest in the world. A total of 60,041 Finnish men and women who were 26–74 years of age and without history of any cancer at baseline were included in the present analyses. Coffee consumption and other study parameters were determined at baseline using standardized measurements. Participants were prospectively followed up for onset of gastric and/or pancreatic cancer, emigration, death or until June 30, 2006. During a mean follow-up period of 18 years, 299 cases of gastric cancer and 235 cases of pancreatic cancer were found. There was a nonsignificant inverse association between coffee consumption and risk of gastric cancer among men but not in the women. The multivariate-adjusted hazard ratio of stomach and pancreatic cancer incidence for ≥10 cups of coffee per day compared with nondrinkers were 0.75 (95% CI, 0.40–1.41) (P for trend = 0.19) and 0.82 (95% CI, 0.38–1.76) (P for trend = 0.95) for the combined population of men and women, respectively. We did not find a significant association between coffee consumption and the risk of gastric and/or pancreatic cancers.
