Abstract:
:To determine the relationship between p53 altered expression and p53 mutations in hepatocellular carcinoma (HCC), we analysed p53 protein immunohistochemically and assessed the presence of mutations in exons 4-8 of the p53 gene using SSCP assay in 117 HCCs corresponding to 78 patients. We also determined the relationship of p53 expression with cellular proliferation by immunostaining with monoclonal antibodies to Ki-67. We found significant levels of p53 protein expression in 23.1% of the 117 cases studied, but identified mutations in only 12 cases (10.3%). Only four of the p53-positive cases had mutations in the regions analysed. Six of the cases that displayed mutations at p53 gene were negative for immunohistochemical analysis (IHC) and two cases showed positive immunoreactivity in the cytoplasm of the cell. In conclusion, strong IHC reactivity for p53 protein is not an indicator of the presence of p53 gene mutations at exons 4-8 in HCC. Thus, p53 loss of function in HCC should be evaluated both by p53 mutation analysis and p53 protein expression, as both give complementary information about p53 status.
