    • BACKGROUND: Advanced glycation end products (AGE) and their receptors (RAGE) have been implicated in cancer development through their proinflammatory capabilities. However, prospective data on their association with cancer of specific sites, including pancreatic cancer, are limited.METHODS: Prediagnostic blood levels of the AGE product Nε-(carboxymethyl)lysine (CML) and the endogenous secreted receptor for AGE (esRAGE) were measured using ELISA in 454 patients with exocrine pancreatic cancer and individually matched controls within the European Prospective Investigation into Cancer and Nutrition (EPIC). Pancreatic cancer risk was estimated by calculating ORs with corresponding 95% confidence intervals (CI).RESULTS: Elevated CML levels tended to be associated with a reduction in pancreatic cancer risk [OR = 0.57 (95% CI, 0.32-1.01) comparing highest with lowest quintile), whereas no association was observed for esRAGE (OR = 0.98; 95% CI, 0.62-1.54). Adjustments for body mass index and smoking attenuated the inverse associations of CML with pancreatic cancer risk (OR = 0.78; 95% CI, 0.41-1.49). There was an inverse association between esRAGE and risk of pancreatic cancer for cases that were diagnosed within the first 2 years of follow-up [OR = 0.46 (95% CI, 0.22-0.96) for a doubling in concentration], whereas there was no association among those with a longer follow-up (OR = 1.11; 95% CI, 0.88-1.39; P(interaction) = 0.002).Conclusions and Impact: Our results do not provide evidence for an association of higher CML or lower esRAGE levels with risk of pancreatic cancer. The role of AGE/RAGE in pancreatic cancer would benefit from further investigations. Cancer Epidemiol Biomarkers Prev; ©2012 AACR.

  • Plasma cotinine levels and pancreatic cancer in the EPIC cohort study
  • 2012
  • Ingår i: International Journal of Cancer. - : John Wiley and Sons Inc.. - 0020-7136 .- 1097-0215. ; 131:4, s. 997-1002

    • Smoking is an established risk factor for pancreatic cancer, previously investigated by the means of questionnaires. Using cotinine as a biomarker for tobacco exposure allows more accurate quantitative analyses to be performed. This study on pancreatic cancer, nested within the European Prospective Investigation into Cancer and Nutrition (EPIC cohort), included 146 cases and 146 matched controls. Using liquid chromatography-mass spectrometry, plasma cotinine levels were analyzed on average 8.0 years before cancer onset (595% range: 2.812.0 years). The relation between plasma cotinine levels and pancreatic cancer was analyzed with conditional logistic regression for different levels of cotinine in a population of never and current smokers. This was also done for the self-reported number of smoked cigarettes per day at baseline. Every increase of 350 nmol/L of plasma cotinine was found to significantly elevate risk of pancreatic cancer [odds ratio (OR): 1.33, 95% confidence interval (CI): 1.111.60]. People with a cotinine level over 1187.8 nmol/L, a level comparable to smoking 17 cigarettes per day, have an elevated risk of pancreatic cancer, compared to people with cotinine levels below 55 nmol/L (OR: 3.66, 95% CI: 1.449.26). The results for self-reported smoking at baseline also show an increased risk of pancreatic cancer from cigarette smoking based on questionnaire information. People who smoke more than 30 cigarettes per day showed the highest risk compared to never smokers (OR: 4.15, 95% CI: 1.0216.42). This study is the first to show that plasma cotinine levels are strongly related to pancreatic cancer.

  • Dietary intake of heme iron and risk of gastric cancer in the European prospective investigation into cancer and nutrition study
  • 2012
  • Ingår i: International Journal of Cancer. - : John Wiley and Sons Inc.. - 0020-7136 .- 1097-0215. ; 130:11, s. 2654-2663

    • Even though recent studies suggest that a high intake of heme iron is associated with several types of cancer, epidemiological studies in relation to gastric cancer (GC) are lacking. Our previous results show a positive association between red and processed meat and non cardia gastric cancer, especially in Helicobacter pylori infected subjects. The aim of the study is to investigate the association between heme iron intake and GC risk in the European prospective investigation into cancer and nutrition (EURGAST-EPIC). Dietary intake was assessed by validated center-specific questionnaires. Heme iron was calculated as a type-specific percentage of the total iron content in meat intake, derived from the literature. Antibodies of H. pylori infection and vitamin C levels were measured in a sub-sample of cases and matched controls included in a nested case-control study within the cohort. The study included 481,419 individuals and 444 incident cases of GC that occurred during an average of 8.7 years of followup. We observed a statistically significant association between heme iron intake and GC risk (HR 1.13 95% CI: 1.011.26 for a doubling of intake) adjusted by sex, age, BMI, education level, tobacco smoking and energy intake. The positive association between heme iron and the risk of GC was statistically significant in subjects with plasma vitamin C <39 mmol/l only (log2 HR 1.54 95% CI (1.012.35). We found a positive association between heme iron intake and gastric cancer risk.

  • Dietary total antioxidant capacity and gastric cancer risk in the European prospective investigation into cancer and nutrition study
  • 2012
  • Ingår i: International Journal of Cancer. - : John Wiley and Sons Inc.. - 0020-7136 .- 1097-0215. ; 131:4, s. 544-554
  • Tidskriftsartikel (refereegranskat)abstract
    • A high intake of dietary antioxidant compounds has been hypothesized to be an appropriate strategy to reduce gastric cancer (GC) development. We investigated the effect of dietary total antioxidant capacity (TAC) in relation to GC in the European Prospective Investigation into Cancer (EPIC) study including 23 centers in 10 European countries. A total of 521,457 subjects (153,447 men) aged mostly 3570 years old, were recruited largely between 1992 and 1998. Ferric reducing antioxidant potential (FRAP) and total radical-trapping antioxidant parameter (TRAP), measuring reducing and chain-breaking antioxidant capacity were used to measure dietary TAC from plant foods. Dietary antioxidant intake is associated with a reduction in the risk of GC for both FRAP (adjusted HR 0.66; 95%CI (0.460.95) and TRAP (adjusted HR 0.61; 95%CI (0.430.87) (highest vs. lowest quintile). The association was observed for both cardia and noncardia cancers. A clear effect was observed in smokers with a significant reduction in GC risk for the fifth quintile of intake for both assays (highest vs. lowest quintile: adjusted HR 0.41; 95%CI (0.220.76) p for trend <0.001 for FRAP; adjusted HR 0.52; 95%CI (0.280.97) p for trend <0.001 for TRAP) but not in nonsmokers. In former smokers, the association with FRAP intake was statistically significant (highest vs. lowest quintile: adjusted HR 0.4; 95%CI (0.210.75) p < 0.05); no association was observed for TRAP. Dietary antioxidant capacity intake from different sources of plant foods is associated with a reduction in the risk of GC.

  • Coffee and tea consumption and the risk of ovarian cancer: a prospective cohort study and updated meta-analysis
  • 2012
  • Ingår i: American Journal of Clinical Nutrition. - Bethesda : American Society for Clinical Nutrition. - 1938-3207 .- 0002-9165. ; 95:5, s. 1172-1181
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: In 2007 the World Cancer Research Fund Report concluded that there was limited and inconsistent evidence for an effect of coffee and tea consumption on the risk of epithelial ovarian cancer (EOC). Objective: In the European Prospective Investigation into Cancer and Nutrition (EPIC), we aimed to investigate whether coffee intakes, tea intakes, or both are associated with the risk of EOC. Design: All women participating in the EPIC (n = 330,849) were included in this study. Data on coffee and tea consumption were collected through validated food-frequency questionnaires at baseline. HRs and 95% CIs were estimated by using Cox proportional hazards models. Furthermore, we performed an updated meta-analysis of all previous prospective studies until April 2011 by comparing the highest and lowest coffee- and tea-consumption categories as well as by using dose-response random-effects meta-regression analyses. Results: During a median follow-up of 11.7 y, 1244 women developed EOC. No association was observed between the risk of EOC and coffee consumption [HR: 1.05 (95% CI: 0.75, 1.46) for the top quintile compared with no intake] or tea consumption [HR: 1.07 (95% Cl: 0.78, 1.45) for the top quintile compared with no intake]. This lack of association between coffee and tea intake and EOC risk was confirmed by the results of our meta-analysis. Conclusion: Epidemiologic studies do not provide sufficient evidence to support an association between coffee and tea consumption and risk of ovarian cancer. Am J Clin Nutr 2012;95:1172-81.

  • Physical Activity and Mortality in Individuals With Diabetes Mellitus A Prospective Study and Meta-analysis
  • 2012
  • Ingår i: Archives of Internal Medicine. - : American Medical Association. - 0003-9926 .- 1538-3679. ; 172:17, s. 1285-1295
  • Forskningsöversikt (refereegranskat)abstract
    • Background: Physical activity (PA) is considered a cornerstone of diabetes mellitus management to prevent complications, but conclusive evidence is lacking. Methods: This prospective cohort study and meta-analysis of existing studies investigated the association between PA and mortality in individuals with diabetes. In the EPIC study (European Prospective Investigation Into Cancer and Nutrition), a cohort was defined of 5859 individuals with diabetes at baseline. Associations of leisure-time and total PA and walking with cardiovascular disease (CVD) and total mortality were studied using multivariable Cox proportional hazards regression models. Fixed-and random-effects meta-analyses of prospective studies published up to December 2010 were pooled with inverse variance weighting. Results: In the prospective analysis, total PA was associated with lower risk of CVD and total mortality. Compared with physically inactive persons, the lowest mortality risk was observed in moderately active persons: hazard ratios were 0.62 (95% CI, 0.49-0.78) for total mortality and 0.51 (95% CI, 0.32-0.81) for CVD mortality. Leisure-time PA was associated with lower total mortality risk, and walking was associated with lower CVD mortality risk. In the meta-analysis, the pooled random-effects hazard ratio from 5 studies for high vs low total PA and all-cause mortality was 0.60 (95% CI, 0.49-0.73). Conclusions: Higher levels of PA were associated with lower mortality risk in individuals with diabetes. Even those undertaking moderate amounts of activity were at appreciably lower risk for early death compared with inactive persons. These findings provide empirical evidence supporting the widely shared view that persons with diabetes should engage in regular PA.
