胃癌在全球恶性肿瘤致死亡的原因中位居第二位,幽门螺杆菌(H.pylori)感染是胃癌发生的重要病因。动物研究显示根除H.pylori,特别是在早期阶段,能有效预防胃癌的发生。部分病例通过根除H.pylori可阻止胃癌前病变的发展并可能使其逆转。最新研究表明根除H.pylori可降低胃癌发生的风险,对无萎缩或肠化生者可能尤其有效。本文就根除H.pylori在预防胃癌中作用的研究进展作一综述。
Gastric cancer is the second leading cause of death from malignant tumors in the world. H. pylori infection is an important cause of gastric cancer. Animal studies have shown that the eradication of H. pylori, especially in the early stages, can effectively prevent the occurrence of gastric cancer. In some cases, the eradication of H. pylori can prevent the development of gastric precancerous lesions and may reverse them. Recent research shows that eradicating H. pylori can reduce the risk of gastric cancer and may be particularly effective in patients with or without atrophy. This article summarizes the research progress of eradicating the role of H.pylori in preventing gastric cancer.
