Abstract | Overexpression of the p53 tumour suppressor gene is one of the most common abnormalities in primary human cancers and appears to be a result of point mutation within a highly conserved region of the gene with subsequent encoding for a mutant, more stable, protein. In this study, 71 surgically resected hepatocellular carcinomas (HCC) were examined to study the expression of the p53 gene, its relation with clinicopathological parameters and its prognostic significance. Using immunohistochemical detection for mutant p53 protein with monoclonal antibody PAb1801, p53 overexpression was found in 22 tumours (31%) but in none of the non-tumorous liver specimens. Overexpression of p53 was more frequent in tumours with poor cellular differentiation (P = 0.01), in tumours > 5 cm in diameter (P = 0.05), and in those with giant cells present (P = 0.03) and, less significantly, of massive type of Eggel's classification (P = 0.06). It did not have any significant correlation with hepatitis B or C status, background liver disease or serum α-fetoprotein levels, nor was it related to tumour invasiveness (venous permeation, direct liver invasion and tumour microsatellite formation). In addition, the presence of p53 mutant protein did not influence tumour recurrence or patients' survival rates. The data suggested that p53 mutation in HCC was associated with a later stage of oncogenesis. However, it was not apparently related to tumour invasiveness/aggressiveness and prognosis. |
