METHODS The expressions of MG-3c7 anatigen and cerbB-2 receptor in specimens of GC were detected with the technique of ABC immunnohistochemistry.The DNA content of specimens was determined with flow cytometry(FCM).The data of multi-parameter in methodology were analysed by statistics. RESULTS The expressive rates of MG-3c7 antigen and cerbB-2 receptor were observed in gastric tublar adenocarci- noma(GTA,100% and 56%),adenocarcinoma(AC,58% and 50%),and normal gastric mucosa(NGM,20% and 33%). respectively The DNA heteroploid rate was 63%(12/19)in GTA,75%(3/4)in AC and 0%(0/8)in NGM.In Detecting GTA with FCM and ABC method,the histological parameter analysis synthetically showed that the sensitivity was 82.3% specificity 88%,expentancy 95.4% and accuracy 84%.Both methods were complementary. CONCLUSIONS The synthetic diagnosis and analysis of multi-parameter and the study on histomorphology and molecular biology may be a new way for the diagnosis on GC in histology.展开更多
