Abstract:

GOAL: Determine whether various dimensions of smoking increase risk for gastric intestinal metaplasia. BACKGROUND: Cigarette smoking has been implicated in the etiology of gastric cancer, but it is not clear if smoking is a risk factor for gastric intestinal metaplasia, a precursor lesion of gastric cancer. MATERIALS AND METHODS: We compared data from 385 gastric intestinal metaplasia cases and 1577 controls without gastric intestinal metaplasia recruited into a cross-sectional study at the Michael E. DeBakey VA Medical Center in Houston, Texas. All participants completed standardized questionnaires and underwent a study endoscopy with gastric mapping biopsies. Gastric intestinal metaplasia cases included participants with intestinal metaplasia on any noncardia gastric biopsy. We calculated odds ratios and associated 95% confidence intervals using multivariable logistic regression models. RESULTS: Compared with never smokers, current smokers had 2-fold increased risk for gastric intestinal metaplasia (odds ratio, 2.05; 95% confidence interval, 1.47-2.85). Among ever smokers, increasing duration and total dose were significantly associated with increased risk for gastric intestinal metaplasia (P-trend, 0.004 and 0.01, respectively). Among former smokers, risk for gastric intestinal metaplasia decreased over time and was no different to never smokers after 15 years smoking cessation. Cases with gastric intestinal metaplasia were more likely than controls to have Helicobacter pylori infection (53.2% vs. 21.7%); however, smoking effect on gastric intestinal metaplasia was not different by H. pylori infection status. CONCLUSIONS: Cigarette smoking is a risk factor for gastric intestinal metaplasia. Risk of gastric intestinal metaplasia among former smokers remained significantly elevated until 15 years postcessation.
