ABSTRACT

Objective To explore the possibility of united test of CA72-4, CA19-9 in gastric juice in diagnosis of gastric carcinoma.Methods The gastric juices were respectively obtained by liquid collector made by ourselves through gastreecope in study group(30 cases of gastric cancer) and control groups(32 cases of gastratrophia,30 cases of gastric ulcer,and 30 cases of chronic superficial gastritis).The gastric juice content of CA72-4, CA19-9 were determined synchronously with ES-300 auto-enzymoimmuno-analyzer.Results The gastric juice contents of CA72-4,CA19-9 were (83.54±143.70) U/ml and (47.05±29.64) U/ml, and the positive rates were 76.66% and 43.33% in study group,respectively,and all higher than those of control groups(P <0.01 ).The level of CA72-4 was high in two of 32 patients with gastratrophia,and one was diagnosed as gastric carcinoma after nine months follow-up.Conclusion The combined detection of CA72-4 and CA19-9 provide main evidence for the diagnosis of gastric cancer and diagnostric significance of advanced gastric cancer.
