Abstract

Conventional teaching is that Helicobacter pylori infection is required for the development of non-cardia gastric adenocarcinoma (NCGC) through a sequence of atrophic gastritis, intestinal metaplasia, dysplasia, and finally, cancer. However, studies have not demonstrated a 100% rate of H pylori infection in gastric malignancy, hypothesized to be due to false negatives, gastric atrophy leading to apparent loss of infection, and inclusion of cardia, nonintestinal cancers..

摘要

传统观点认为,幽门螺杆菌(Helicobacter pylori,H.pylori)感染是导致非贲门胃腺癌(non-cardia gastric adenocarcinoma,NCGC)发生的必要条件,其发展过程依次为萎缩性胃炎、肠化生、异型增生,最终进展为癌症。然而,研究并未在所有胃恶性肿瘤中均发现 100%的 H.pylori 感染率,这被认为是由于假阴性、胃萎缩导致的明显感染丢失以及贲门、非肠型癌症的包含等因素所致。
