We read with interest the report by Doorakkers et al describing the effect of Helicobacter pylori eradication in preventing the development of non-cardia gastric adenocarcinoma in a population-based Swedish cohort.1 The authors used nationwide Swedish registries to investigate the incidence of gastric adenocarcinoma after H. pylori eradication treatment. Specifically, standardised incidence ratios (SIRs) were used to examine the incidence of gastric adenocarcinoma in individuals treated for H. pylori compared with a background population of corresponding age, sex and calendar year distribution. The time trend of the SIRs after H. pylori eradication was assessed for up to 7.5 years. The results showed that the risk of non-cardia gastric adenocarcinoma sharply decreased over time after …

治疗幽门螺杆菌似乎降低胃癌发病率：根除效果还是筛查效果？

我们饶有兴趣地阅读了 Doorakkers 等人的报告，该报告描述了在以人群为基础的瑞典队列中根除幽门螺杆菌对预防非贲门胃腺癌发展的影响。 H. pylori 根除治疗。具体而言，标准化发病率 (SIR) 用于检查接受幽门螺杆菌治疗的个体与相应年龄、性别和日历年分布的背景人群相比的胃腺癌发病率。根除 H. pylori 后 SIR 的时间趋势评估长达 7.5 年。结果表明，非贲门胃腺癌的风险随着时间的推移而急剧下降……
