胃癌发病居我国消化道恶性肿瘤首位,辽东半岛是高发地区,而1/3胃癌病人早期无症状,在我院门诊确诊之胃癌98％以上为晚期病例。日本以胃肠气钡双对照与胃镜普查发现早期胃癌占确诊病人30～50％,取得显著效果。国内多采用一组非特异性互补方法,以期胃癌早期发现。本院从1979年设计二级普查法,连续3年在皮口、安波等地普查5101人。初筛结果:其中胃液,血液化验资料完整者431例。胃液pH:pH7.0-180例,pH6.0-29例,pH5.0-31例,pH4.0-71例,pH3.0以下者120例;胃液潜血(OB):OB(+)以上者86例,OB(-)者345例;血清耐热试验(WT):WT(+++)-3例,WT(++++)-8例,
The incidence of gastric cancer ranks first in the gastrointestinal cancer in China. Liaodong Peninsula is a high-risk area, and 1/3 of gastric cancer patients are asymptomatic in the early stage. More than 98% of gastric cancer diagnosed in our hospital is advanced. In Japan, a double-control gastroenteroscopy and gastroscopy survey found that early gastric cancer accounted for 30 to 50% of diagnosed patients, and achieved significant results. In China, a set of non-specific complementary methods are used to achieve early detection of gastric cancer. The hospital designed a two-level census method from 1979 and surveyed 5,101 people for 3 consecutive years in the town of Pico and Anbo. Primary screening results: 431 cases of gastric fluid and blood laboratory data were complete. Gastric juice pH: pH7.0-180 cases, pH6.0-29 cases, pH5.0-31 cases, pH4.0-71 cases, pH3.0 or less 120 cases; gastric occult blood (OB): OB (+) or more 86 cases, OB (-) were 345 cases; serum heat resistance test (WT): WT (+++)-3 cases, WT (++++)-8 cases,
