    • The risk of gastric stump carcinoma is increased 15-20 years after gastric resection for benign disease. Reflux of duodenal juice, bacterial overgrowth and formation of N-nitroso compounds are possible etiological factors. There is a geographical variation in the incidence of gastric cancer, possibly explained by differences in food intake. Experimentally it is possible to induce gastric stump carcinoma in rats without the addition of exogenous carcinogens. The aim of this study was: 1) to find the incidence of gastric carcinoma in rats subjected to BII resection and followed for 10 months, and 2) to examine if acetic acid, a common dietary factor, could influence the development of gastric carcinoma. Amongst BII-operated male Wistar rats, infiltrating carcinoma was found in 5/20 on a normal diet and in 5/24 exposed to acetic acid (NS). Benign mucosal changes were seen in 12/20 and 16/24 respectively (NS). With the exception of a profound inflammation in one sham-operated animal, no mucosal pathological changes were found in 24 sham-operated and 24 control animals where no operation was performed.

  • Fruit and vegetable intake and the risk of gastric adenocarcinoma: A reanalysis of the european prospective investigation into cancer and nutrition (EPIC-EURGAST) study after a longer follow-up
  • 2012
  • Ingår i: International Journal of Cancer. - : Wiley. - 0020-7136. ; 131:12, s. 2910-2919
  • Tidskriftsartikel (refereegranskat)abstract
    • In a previous European prospective investigation into cancer and nutrition (EPIC) analysis, we found an inverse association between total intake of vegetables, onion and garlic, and risk of intestinal gastric cancer (GC) and between citrus fruit and risk of cardia GC. The aim of this study is to reanalyze the effect of fruit and vegetables (F&V), based on a longer follow-up and twice the number of GC cases. Subjects are 477,312 men and women mostly aged 35 to 70 years participating in the EPIC cohort, including 683 gastric adenocarcinomas with 11 years of follow-up. Information on diet and lifestyle was collected at baseline. A calibration study in a subsample was used to correct for dietary measurement errors. When comparing the highest vs. lowest quintile of intake, we found an inverse association between total intake of V&F and GC risk [hazard ratio (HR) 0.77; 95% confidence interval (CI) 0.571.04; p for trend 0.02], between fresh fruit and risk of the diffuse type (HR 0.59; 95% CI 0.360.97; p for trend 0.03) and an inverse association between citrus fruit and risk of cardia cancer (HR 0.61; 95% CI 0.381.00, p for trend 0.01). Although calibration revealed somewhat stronger inverse associations, none of the risks reached statistical significance. There was no association between total or specific vegetables intake and GC risk. The inverse association between fresh fruit and citrus fruits and risk of GC seems to be restricted to smokers and the Northern European countries. Fresh fruit and citrus fruit consumption may protect against diffuse and cardia GC, respectively.
