GASTRIC ADENOCARCINOMA
Etiology. III. Other factors
* gastric ulcers and adenomatous polyps (but
unconvincing data on a cause / effect relationship = e.g.,
inadequate clinical distinction between benign gastric
ulcers and small ulcerating GC);
- Menetrier's disease (extreme hypertrophy of gastric
rugal folds mimics polypoid lesions, but does not represent
true adenomatous polyps);
- blood group A have ↑ incidence of GC than blood
group 0 individuals (possibly due to # in mucous secretion
of various ABO groups → greater or lesser mucosal
protection from carcinogens);
- no association between duodenal ulcers and GC
