至今,还没有一项随机实验表明对选定的人群筛查胃癌能挽救生命。事实上所有的消化不良的处理准则都推荐年龄大于45岁、近期出现或治疗无效的消化不良者,须行内镜检查以排除癌肿。本研究目的是确定对45～55岁的消化不良患者进行筛查的看法是否有充分根 To date, no randomized trials have shown that screening for gastric cancer in selected populations can save lives. In fact, all guidelines for indigestion are recommended for those who are older than 45 years, who have recently developed or have failed to treat indigestion, and who must undergo endoscopy to rule out cancer. The purpose of this study was to determine if there is a sufficient view of the screening of patients with dyspepsia 45 to 55 years of age.
