摘要

Early gastric cancer is the gastric cancer limited to mucosa or submucosa no matter there is lymph node metastasis or not,and its prognosis is relatively good. China is the high morbidity area of gastric cancer,most patients with gastric cancer are diagnosed at an advanced stage losing the chance of operation and the survival rate is low. Therefore, early diagnosis and treatment is crucial for improving the survival rate of patients with gastric cancer. This article reviewed the progress in study on diagnosis of early gastric cancer from the following aspects:serology,imaging,endoscopy and genetics.%早期胃癌是指病变局限于黏膜或黏膜下层的胃癌，无论有无淋巴结转移，预后相对良好。我国属于胃癌高发国家，患者确诊时多属中晚期，失去手术机会，生存率低。因此，早诊断、早治疗是提高胃癌患者生存率的关键。本文从血清学检测、影像学检查、内镜检查以及基因检测四个方面就早期胃癌诊断的研究进展作一综述。
