ABSTRACT
Objective:To evaluate p53,c erbB 2,p21 and nm23 oncoprotein expression in diagnosis and treatment of gastric cancer.Methods:The expression of p53,c erbB 2,p21 and nm23 oncoproteins was detected with immunohistochemical method in 63 surgically resected specimens and its endoscopic biopsy specimens of gastric cancer.Results:The positive rates of p53,c erbB 2,p21 and nm23 oncoprotein expression were 37 6%~46 2%,34 6%~56 8%,37 8%~61 5%,70 3%~30 8% respectively.Oncoprotein expression was not observed in non tumor endoscopic biopsy specimens.The expression of c erbB 2,p21 was correlated with grade of tumor differentiation and the expression of p21,nm23 oncoproteins was correlated with the depth of tumor invasion and clinical different stage,namely tumor metastasis.Positive rates of p53,c erbB 2,p21 and nm23 oncoproteins between biopsy and resected specimens was of coincidence.Conclusion:Determination of p53,c erbB 2,p21 and nm23 oncoprotein expression was might be useful in diagnosis and treatment of gastric cancer,differentiating benign and malignant tumor and clinical stages,of gastric cancer.
