We thank the members of the panel of pathologists for their valuable work: Dr R.S. Umea, Sweden; Dr U. Mahlke, Postdam, Germany; Dr Hendrik Bläker, Heildelberg, Germany; Dr Gabriella Nesi, Firenze, Italy; Dr Vicki Save, Cambridge, UK; Dr Claus Fenger, Copenhagen, Denmark; Dr Julio Torrado, San Sebastian, Spain; Dr Johan Offerhaus, Amsterdam, The Netherlands; Ioannina, Greece. We also thank Dr Dimitrious Roukos and Cátia Moutinho, Porto, Portugal, for her excellent technical support to the panel of pathologists. Specific study results of the nested case–control study within EPIC (EUR-GAST) were obtained with financial support from the FP5 of European Commission (QLG1-CT-2001-01049). The participation of P.J. in the project is supported by a grant of the ‘Fundació Privada Institut d’Investigació Biomèdica de Bellvitge (IDIBELL).

N2 - The risk of gastric cancer (GC) associated with dietary intake of nitrosodimethylamine (NDMA) and endogenous formation of nitroso compounds (NOCs) was investigated in the European Prospective Investigation into Cancer and Nutrition (EPIC). The study included 521 457 individuals and 314 incident cases of GC that had occurred after 6.6 average years of follow-up. An index of endogenous NOC (ENOC) formation was estimated using data of the iron content from meat intake and faecal apparent total NOC formation according to previous published studies. Antibodies to Helicobacter pylori and vitamin C levels were measured in a sub-sample of cases and matched controls included in a nested case-control within the cohort. Exposure to NDMA was <1 μg on average compared with 93 μg on average from ENOC. There was no association between NDMA intake and GC risk (HR, 1.00; 95% CI, 0.7-1.43). ENOC was significantly associated with non-cardia cancer risk (HR, 1.42; 95% CI, 1.14-1.78 for an increase of 40 μg/day) but not with cardia cancer (HR, 0.96; 95% CI, 0.69-1.33). Although the number of not infected cases is low, our data suggest a possible interaction between ENOC and H.pylori infection (P for interaction - 0.09). Moreover, we observed an interaction between plasma vitamin C and ENOC (P < 0.02). ENOC formation may account for our previously reported association between red and processed meat consumption and gastric cancer risk.
