ABSTRACT
Introduction: Gastric cancer has been reported to occur with mild to moderate mucosal atrophy, particularly after the eradication of Helicobacter pylori (HP) more than 10 years previously. However, no conclusion has been reached on how many years of esophagogastroduodenoscopy should be performed after HP eradication. Presentation of case: This was a case of gastric carcinoma of the fundic gland type (GCFGT) 32 years after the eradication of HP, which is the longest posteradication period reported. A 62-year-old male patient was diagnosed with GCFGT after HP eradication and regular esophagogastroduodenoscopy, which revealed a white raised lesion on the anterior wall of the upper part of the body. Endoscopic submucosal dissection was performed for GCFGT, and the vertical and horizontal margins were negative. Clinical discussion: In this case, HP was eradicated in 1990, and GCFGT developed 32 years later. To the best of our knowledge, this is the longest case in which gastric cancer appeared after HP eradication. HP eradication therapy for a duodenal ulcer was first reported in 1990, supporting that this is the longest case. Conclusions: This is the first case of gastric cancer more than 20 years after the eradication of HP. The endoscopic findings of this case are typical of GCFGT and may be useful when encountering such cases in the future. Therefore, the risk of gastric cancer should be considered for an extended period even after the eradication of HP, and regular esophagogastroduodenoscopy is recommended even after the eradication of HP.
ABSTRACT
AIM: To explore the endoscopic features and risk factors of early gastric cancer (EGC) after eradication of Helicobacter pylori (H. pylori). METHODS: A total of 1961 patients who underwent esophago-gastro-duodenoscopy (EGD) with a history of successful H. pylori eradication were enrolled in this multicenter research. Among them, 162 EGC lesions of 132 patients were detected. The endoscopic features and risk factors of post-eradication EGC were explored. RESULTS: Severe atrophy (75.3% vs. 16.7%, p value <.01), intestinal metaplasia (96.3% vs. 77.1%, p value <.01), map-like redness (89.5% vs. 65.4%, p value <.01), distinct intermediate zone (IZ) (68.5% vs. 23.4%, p value <.01) and xanthoma (58.0% vs. 17.9%, p value <.01) were significantly more frequent in the CA group (patients with newly detected EGC after eradication of H. pylori) than in the NC group (patients without gastric cancer after eradication of H. pylori). In multivariate analysis, severe atrophy (odds ratio (OR) = 8.08; 95% confidence interval (CI), 3.43-20.0; p value<.01), map-like redness (OR = 1.75; 95% CI, 0.11-5.25; p value = .04), distinct IZ (OR = 2.87; 95% CI, 1.20-6.93; p value = .02) and xanthoma (OR = 2.84; 95% CI, 1.20-7.03; p value=.02) were proved to be risk factors for detection of EGC after eradication of H. pylori. CONCLUSIONS: Severe atrophy and map-like redness and distinct IZ and xanthoma are risk factors of EGC after eradication of H. pylori.

Helicobacter pylori eradication therapy for chronic gastritis achieved world-first coverage by the Japanese national health insurance scheme in 2013, making a dramatic decrease of gastric cancer-related deaths more realistic. Combining H pylori eradication therapy with endoscopic surveillance can prevent the development of gastric cancer. Even if it develops, most patients are likely to be diagnosed at an early stage, possibly resulting in fewer gastric cancer deaths. Success with the elimination of gastric cancer in Japan could lead other countries with a high incidence to consider a similar strategy, suggesting the potential for elimination of gastric cancer around the world.

Objective To analysis curative effect of triple therapy and sequential therapy for eradication of Helicobacter pylori in patients with long-term aspirin use.Methods 52 patients with long-term aspirin use who were diagnosed with helicobacter pylori infection were collected.All patients were divided into sequential group and triple group according to different drugs classified, each 26 cases in each group were given corresponding drug treatment, after the end of treatment, the serum pepsinogen, Hp-IgG antibody levels and Helicobacter pylori clearance rate were detected in all patients. Results After treatment, compared with the triple Group, in the sequential group, the levels of serum PG I and PG II were lower, and PGⅠ/PGⅡwas higher, and the differences were statistically significant (P<0.05);the serum Hp-IgG antibody levels were lower in the sequential group (P<0.05);the Hp clearance rate of patients in the sequential group was higher (P<0.05).Conclusion Compared with triple therapy, sequential therapy can lower serum PG, PG II and Hp-IgG levels, and improve the Hp clearance rate and clinical efficacy, have guiding significance to clinical.
