2. Risk of Gastric Cancer after
Billroth II
• Many studies show
• NO INCREASED RISK
• Some studies do show increased risk
• But these are in ulcer patients with
probable HPylori infections
• In the worst studie the increased risk is
• 1.5 X Much less than Meat or H.Pylori
3. Meat is Bad
Increased Gastric Cancer Rates in 6 years
• Gastric cancer risk inversely associated
(i.e. they are GOOD)
• High vitamin C, Carotenoids, Retinol and
α-tocopherol, high intake of cereal Fibre
and high adherence to Mediterranean diet
• Red and processed meat were associated
with increased risk Gastric cancer
4. Meat - Nitroso compounds (NOCs)
• Risk of gastric cancer (GC) associated
with dietary intake of nitrosodimethylamine
(NDMA) and endogenous formation of
nitroso compounds (NOCs)
• NOC was significantly associated with
non-cardia cancer risk 1.42 x times
• Carcinogenesis. 2006 Jul;27(7):1497-501. Epub 2006 Mar 29 Endogenous versus exogenous
exposure to N-nitroso compounds and gastric cancer risk in the European Prospective
Investigation into Cancer and Nutrition (EPIC-EURGAST) study.
5. Meat intake and risk of stomach
cancer
• Association risk of gastric cancer and
• total meat intake was
• especially large in H. pylori-infected subjects
• odds ratio per 100-g/day increase = X 5.32
• J Natl Cancer Inst. 2006 Mar 1;98(5):345-54. Meat intake and risk of stomach and esophageal
adenocarcinoma within the European Prospective Investigation Into Cancer and Nutrition (EPIC).
6. Fear Gastric Cancer?
Fear the Hot Dog
Not the Billroth II
• 100-g/day increase = X 5.32
• 1 Hot Dog 50-100 g processed meat
• 6 years => 5+ increased risk gastric
cancer
9. H.Pylori increase
Gastric Cancer 6.5 X Times
• Risk of GC associated with HPylori CagA
increase 6.5 X Times
• Causal relationship between H. pylori
CagA+ strains infection, and GC in these
European populations even after taking
into account dietary habits.

risk in the EPIC-EURGAST study.
