本组共检测260例,其中正常健康对照31例,各种胃部疾患229例(其中胃癌47例)。根据对正常人胃液检测结果,IgG与IgA含量分别在200μg/ml和50μg/ml以上者为阳性。以胃液检测lgG和IgA的方法,胃癌的阳性率分别达93.6%和87%,而良性胃疾患的阳性串仅分别为8.8%和5.5%,与目前国内外报道的诊断胃癌的其它免疫学方法比较,具有阳性 A total of 260 cases were examined in this group, of which 31 were normal healthy controls and 229 were various stomach disorders (including 47 cases of gastric cancer). According to the normal human gastric juice test results, IgG and IgA levels were positive at 200 μg/ml and 50 μg/ml or more, respectively. Using gastric fluid to detect lgG and IgA, the positive rates of gastric cancer were 93.6% and 87%, respectively, while the positive strings of benign gastric diseases were only 8.8% and 5.5%, respectively, and other immunological methods for the diagnosis of gastric cancer reported at home and abroad.
