Gastric cancer is one of the most common cancers worldwide. Gastric cancer is a multifactorial disease, and the incidence varies widely by geographic region, with half of new cases occurring in East Asia. Population-based nationwide screening for gastric cancer has been implemented in some Eastern Asian countries such as South Korea and Japan. In these countries, endoscopic screening decreased gastric cancer mortality. Endoscopic screening seems to be a cost-effective modality in countries with high incidence of gastric cancer. However, the usefulness of population-based screening has not yet been proved in countries with low incidence of gastric cancer.
胃癌是全球最常见的癌症之一。胃癌是一种多因素疾病，其发病率因地理区域而异，有一半的新发病例发生在东亚。韩国和日本等一些东亚国家已经实施了基于人群的胃癌全国筛查。在这些国家，内镜筛查降低了胃癌死亡率。内镜筛查在胃癌发病率高的国家似乎是一种具有成本效益的方式。然而，在胃癌发病率低的国家，基于人群的筛查的有效性尚未得到证实。
