Two cases (one nodule-in-nodule case and another case with closely attached HCC and HGDN) showed several overlapped driver mutations (CTNNB1 and CEBPA) and CNAs (losses of CDKN2A, RB1, and TP53) between HGDNs and HCCs, suggesting their roles in the early HCC development.

In addition, it has been shown that the p53 mutation was significantly associated with the diameter of tumor nodule and the degree of cellular differentiation in hepatocellular cancer.

In the present study, the p53 tumor suppressor gene was analyzed by immunohistochemistry in 31 hepato-cellular carcinomas (HCCs) containing two or more regions in the same nodule with different histologic grades. p53 was overexpressed in the nucleus in 13 of 31 HCCs (42%), in seven of which p53 overexpression was seen only in the less-differentiated area of the tumor.

The cellular origins of hepatocellular carcinoma were analysed by p53 genotype. p53 mutation rates were found to be 69.0% (20/29) in the primary and recurrent tumours, 58.8% (10/17) in tumours with a single nodule and 83.3% (10/12) in tumours with multiple nodules.
