ABSTRACT

Objective To investigate the role of the expressions of APC,bcl-2 and c-met gene in the progress of gastric cancer and their significances in the diagnosis of early gastric cancer.Methods The immunohistochemical technique was used to detect the expressions of APC,bcl-2 and c-met gene in 30 cases of human gastric carcinoma(GC),30 cases of intestinal metaplasia(IM),30 dysplasia(Dys) gastric mucosa,10 gastric adenoma(GA) and 20 normal gastric mucosa.Results ①The positive expression rates of APC in GC,IM,Dys and GA(53.3%,67.7% and 53.3%,respectively) were significantly lower than those in normal gastric mucosa(90.0%,P
