Gastric cancer is the second most common cause of cancer death worldwide and is usually detected at a late stage, except in Korea and Japan where early screening is in effect. Results from animal and epidemiological studies suggest that Helicobacter pylori infection, and subsequent gastritis, promote development of gastric cancer in the infected mucosa. Relatively effective treatment regimens are available to treat H. pylori infection, and in general, mass eradication of the organism is not currently recommended as a gastric cancer prevention strategy. However, regional guidelines vary regarding the indications and recommendations for H. pylori treatment for gastric cancer prevention. In this review, we discuss the results from intervention studies, provide insight regarding current guideline recommendations, and discuss future study directions.
胃癌是全球第二大常见癌症死因,通常在晚期才被发现,但在韩国和日本,早期筛查已得到实施。动物和流行病学研究的结果表明,幽门螺杆菌感染及其随后的胃炎会促进感染黏膜中胃癌的发展。目前已有相对有效的治疗方案可用于治疗 H. pylori 感染,通常不建议大规模根除该病原体作为胃癌预防策略。然而,针对胃癌预防的 H. pylori 治疗的适应证和推荐意见,各地区指南存在差异。在这篇综述中,我们讨论了干预研究的结果,提供了关于当前指南建议的见解,并讨论了未来的研究方向。
