我国有不少地区曾开展胃癌普查。使用的方法各有不同,但总的原则是“梯度筛选”,其程序和检测的内容大致可归纳为:1.选择对象[定点(高发区),定期(1～2年),定人(每年总是以这些人为对象),定单位];2.询问病史;3.体格检查;4.有关生化、免疫及其它化验项目的测定;5.脱落细胞检查 Many regions in China have conducted gastric cancer surveys. The methods used are different, but the general principle is “gradient screening,” and the procedures and testing can be roughly summarized as follows: 1. Select the target [fixed point (high incidence area), regular (1 to 2 years), fixed ( Always treat these people as the target), determine the unit]; 2. Ask for medical history; 3. Physical examination; 4. Assays for biochemical, immunological and other laboratory tests; 5. Exfoliated cell tests
