Abstract:
Objective To evaluate the diagnostic value of expression of MG7-Ag diflferentiation and guidance of follow-up mucosal biopsy in the patients with suspected malignanct gastric ulcer.Methods The expression of MG7-Ag in 58 patients who were suspected as having malignant gastric ulcer under routine endoscopy was studied by immuno-histochemical staining.The follow-up endoscopy was pefformed 1 to 72 weeks(mean 7 weeks)later and biopsy was taken.Results There were 19 cases of gastric carcinoma in 30 patients with positive MG7-Ag expression(63.3%)and only 5 in 28 patients with negative MG7-Ag expression(P＜0.01).Conclusion The positive expression of MG7-Ag is correlated with gastrie carcinoma in patients with suspected malignant gastric ulcer.
