Among 57 patients with NUD, anti-Helicobacter pylori Ab was negative in 5 (8.5%) and positive in 52 patients (91.2%) (p=0.043). This significant difference did not remain after logistic regression for adjustment of confounders (p=0.068). The CagA Ab was positive in 22 (42.3%) patients with cancer and 32 (56.1%) of the NUD group. There was no difference in this regard before (p=0.212) and after (p=0.131) logistic regression analysis.CONCLUSION: Anti CagA Ab does not have a significant value as an independent predictive factor in gastric adenocarcinoma.
