Background/aims: Results of urea breath test (UBT) are related to the severity of atrophic gastritis and the density of Helicobacter pylori (H. pylori). Recently, it has been reported that low UBT values should be considered to suggest the possibility of gastric cancer. This study compares UBT results in gastric cancer patients with those of peptic ulcer and gastritis patients.

Methodology: Between October 1998 and May 2000, we have consecutively collected 564 H. pylori-positive patients: 128 gastritis patients, 72 gastric cancer patients, 64 gastric ulcer patients and 300 duodenal ulcer patients. Peptic ulcers were classified into active (A), healing (H), and scar (S) stages. Gastric cancer was classified into early stage (EGCA) and advanced stage (AGCA). The dose of 13C-urea was 50mg, and breath samples were analyzed with a mass spectrometer and the data was evaluated by Mann-Whitney test. The cut...
