Histological characteristics of gastric mucosa prior to Helicobacter pylori eradication may predict gastric cancer

Abstract Objective. Although Helicobacter pylori (H. pylori) eradication has been shown to inhibit gastric cancer, it does not completely suppress it. Therefore, risk factors of gastric cancer development following H. pylori eradication were examined. Material and methods. A total of 2355 patients (1501 males and 824 females) underwent successful eradication of H. pylori. Endoscopic atrophy, histological gastritis, atrophy, intestinal metaplasia (IM), and operative link for gastritis assessment (OLGA) staging were subsequently evaluated. Results. Following eradication, 33/2355 patients (25 males and 8 females) developed gastric cancer. Compared to a nongastric cancer group that was matched according to gender and age, the incidence of endoscopic atrophy (3.52 ± 1.45 vs. 4.85 ± 1.18, p < 0.001), histological atrophy at the greater curvature of the antrum (1.42 ± 0.80 vs. 1.95 ± 0.86, p = 0.0059), inflammation (2.05 ± 0.59 vs. 2.33 ± 0.66, p = 0.031), IM at the greater curvature of the corpus (0.06 ± 0.30 v...
