Abstract
Objective: Several  studies have shown an inverse relation between vegetable and fruit  intake and pancreatic cancer, but no specific                      beneficial component of such foods has been  consistently identified. We considered the role of 15 selected vitamins  and carotenoids                      and 6 minerals on pancreatic cancer risk in an  Italian case–control study.
Methods: Subjects were  326 patients with incident pancreatic cancer and 652 controls, admitted  to the same hospitals as cases for                      acute conditions. Micronutrient computation was  based on a validated and reproducible food-frequency questionnaire. We  estimated                      the odds ratios (OR) and confidence intervals (CI)  using conditional logistic regression models, adjusted for various  confounding                      factors and for energy intake, according to the  residual model.
Results: Comparing the  highest to the lowest quintile of intake, the OR were 0.60 (95% CI  0.36–0.98) for vitamin E, 0.44 (95% CI 0.27–0.73)                      for vitamin C, 0.56 (95% CI 0.34–0.93) for folate,  and 0.57 (95% CI 0.35–0.92) for potassium. No significant inverse  associations                      were observed for α-carotene (OR = 0.69, 95% CI  0.43–1.12), β-carotene (OR = 0.64, 95% CI 0.39–1.06), and  β-cryptoxanthin                      (OR = 0.66, 95% CI 0.39–1.09). No relation was  found for other micronutrients considered.
Conclusion: Our findings support a favorable role of vitamins E and C, selected carotenoids, and folate on pancreatic carcinogenesis.
