title: Helicobacter pylori, atrophic fundal gastritis and risk for gastric adenocarcinoma.
abstract: Fundal atrophic gastritis and Helicobacter pylori have been implicated as possible etiologic factors in gastric cancer. This case-control study was performed to determine which risk factor is more closely related to gastric cancer. The endoscopic Congo red test was performed to evaluate the extent of fundal atrophic gastritis in 43 patients with gastric cancer and 86 cancer-free control subjects, who were individually matched by age, sex, and date of endoscopy (within 3 months). The prevalance of H. pylori infection and severe fundal gastritis were significantly higher in patients with differentiated adenocarcinoma, but not with undifferentiated adenocarcinoma, than in control subjects. The odds ratios for differentiated and undifferentiated adenocarcinomas were 6.85 (95% confidence interval, 1.94-11.82) and 1.50 (95% CI, 0.84-3.11), respectively. However, the odds ratio of H. pylori infection was greater than that of severe fundal gastritis. Moreover, multivariate analysis provided similar results. H. pylori infection is an independent indicator of a higher risk of the differentiated adenocarcinomas of the stomach than is severe fundal gastritis.
