ABSTRACT
AIM: To study the expression of MDM2 and muta nt-type P53 proteins in primary hepatocellular carcinoma(HCC). METHODS: Using immunohistochemical staining method(SP),the expression of mutant-t ype P53 and MDM2 proteins was examined in 55 cases of HCC,23 cases of correspond ing paracancerous tissues and 10 cases of normal hepatic tissues. RESULT S: The frequencies of MDM2 and P53 positive expression in HCC were 17/55 (30 9%) and 23/55 (41 8%), respectively. There was both positive expression of MDM2 and mutant-type P53 in 11 cases (20%) with HCC. Expression of MDM2 showed a significantly positive correlation with expression of mutant-type P53 (r=0 310,P
