China has great burden of gastric cancer, and the diagnosis rate of early gastric cancer is relatively low (<10%). To perform screening, early endoscopic diagnosis and treatment of gastric cancer in high-risk population is a feasible and efficient way to change the current status. Therefore, the Chinese Society of Digestive Endoscopy recently issued Consensus on screening, "Endoscopic diagnosis and treatment of early gastric cancer screening in China". The consensus suggests a feasible and efficient strategy for early detection of gastric cancer: screening with non-invasive procedures, followed by intensive endoscopic examination for screened high-risk population. In this article, we also describe the current status, the causes, high-risk population and early diagnosis of gastric cancer in China; and review the new development of serology and endoscopic techniques for early diagnosis.
我国是胃癌大国，胃癌早期诊断率低（ < 10%），在胃癌高危人群中进行筛查和内镜早期诊断、早期治疗是改变我国胃癌诊治现状的高效可行途径。为此，中华医学会消化内镜学分会等制定了《中国早期胃癌筛查及内镜诊治共识意见》。本文对该共识意见中我国胃癌诊治现状、病因、高危人群以及如何提高早期胃癌诊断率做了解读，并综述了近几年血清学检查和内镜技术在早期胃癌诊断中的应用进展。该共识认为，采用非侵入性诊断方法筛选出胃癌高风险人群，继而进行有目的的内镜下精查是较为可行且高效的诊断策略。
