以正常胃粘膜和5个胃癌的3MKCL提取物作抗原应用FTEEM试验对149例胃癌、良性胃病、其它肿瘤及正常人进行测检。以正常胃粘膜作抗原,各受试组FTEEM仅出现个别阳性。应用单个胃癌抗原检测胃癌病人阳性率为71.43％,而用5个胃癌抗原阳性率可提高到90.49％。应用胃癌提取物作抗原在其它肿瘤病人中均存在不同程度的FTEEM交叉反应。结果表明,应用多种胃癌提取物作抗原可提高胃癌患者FTEEM阳性率。如能进一步扩大抗原成分,并对抗原进行各种非特异性物质的吸收纯化,将会提高其特异性和敏感性。
Using normal gastric mucosa and 5 gastric cancer 3MKCL extracts as antigens, 149 cases of gastric cancer, benign gastropathy, other tumors and normal persons were examined by FTEEM. Using normal gastric mucosa as an antigen, each test group showed only positive individual FTEEM. The positive rate of gastric cancer patients using single gastric cancer antigen was 71.43%, while the positive rate of five gastric cancer antigens could be increased to 90.49%. There are different degrees of FTEEM cross reaction in patients with other tumors using gastric cancer extract as antigen. The results showed that the use of multiple gastric cancer extracts as antigens can increase the positive rate of FTEEM in gastric cancer patients. If you can further expand the antigen composition and absorb and purify various non-specific substances, the specificity and sensitivity will be improved.
