RESULTS: Ten gastric neoplasia cases (gastric cancer and adenoma) were found to be included. Multiple logistic regression analyses identified H. pylori antibody titer ≥3 U/ml (odds ratio=14.4, 95% confidence interval=2.7-76.9; p<0.01) and pepsinogen-I/II ratio ≤4.3 ng/ml (odds ratio=10.0, 95% confidence interval=2.1-47.9; p<0.01), but not age as independent predictive factors of neoplasia.
CONCLUSION: Endoscopy should be considered in individuals with H. pylori antibody titer of ≥3 U/ml and a pepsinogen-I/II ratio of ≤4.3 in those classed as group A by ABC method.
BACKGROUND/AIM: Individuals negative for Helicbacter pylori antibody and with a normal pepsinogen test (group A) are regarded as being at low risk in serum gastric cancer screening known as the ABC method, and endoscopy is not recommended; however, this group may include 2-10% of gastric cancer cases.
PATIENTS AND METHODS: A total of 345 individuals who underwent upper gastrointestinal endoscopy and were classified by ABC as group A (H. pylori antibody titer <10 U/ml, and pepsinogen-I >70 ng/ml or I/II ratio >3) were enrolled, and predictors of gastric neoplasia were investigated.
