Abstract

Background: To date, only a few risk factors for pancreatic cancer have been established. We examined prospectively relations between several medical conditions and pancreatic cancer incidence. Methods: In 1986, 120 852 participants completed a baseline questionnaire on cancer risk factors, including several self-reported physician diagnosed medical conditions. At baseline, a random subcohort of 5000 participants was selected using a case-cohort approach for analysis. After 16.3 years of follow-up, 448 pancreatic cancer cases (63% microscopically confirmed) were available for analysis. Results: Diabetes mellitus type II and hepatitis were positively associated with pancreatic cancer risk (multivariable-adjusted hazard ratio: 1.79; 95% confidence interval: 1.12-2.87 and hazard ratio: 1.37; 95% confidence interval: 1.04-1.81, respectively). Furthermore, a positive trend in risk with increasing years of diagnosis of diabetes (P = 0.004) and of hepatitis (P = 0.02) was observed. However, an inverse association was observed between hypertension and pancreatic cancer risk, this was found among microscopically confirmed cases only (hazard ratio: 0.66; 95% confidence interval: 0.49-0.90), while years since diagnosis of hypertension significantly decreased cancer risk (P for trend 0.02). Conclusion: In this prospective study, a positive association was observed between self-reported physician diagnosed diabetes mellitus type II and hepatitis and pancreatic cancer risk, whereas an inverse association was observed with hypertension.
