Pathological diagnosis of hepatic tumors is sometimes difficult when performed with only routine examinations such as Hematoxylin and Eosin (H.E.) stain. The diagnostic usefulness of KM01 was compared to that of alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), CA19-9 and ras p21 in this immunohistochemical study. AFP was positive in about half of the cases of hepatocellular carcinoma and hepatoblastoma, and AFP-positive cells were frequently found at the periphery of acini in both diseases. Absorbed CEA stain was mostly negative in hepatocellular carcinoma, but was positive in the cells of mixed hepatocellular and cholangiocellular carcinoma (MHCC) and metastatic liver cancer, especially in their cytoplasm. CA19-9 immunostaining was completely negative, and was only 3% positive in hepatocellular carcinoma. KM01 stain was positive in about half of the cases of hepatocellular carcinoma, hepatoblastoma and MHCC. It was positive in proliferated bile ducts around the capsule in the former two diseases but positive in the tumor cell of both parts of the cytoplasm in the latter. The histological positivity of ras p21 was high in all tumor cells of these three types of tumors. Negative absorbed CEA and KM01 in pseudoglandular hepatocellular carcinoma differentiated from MHCC and metastatic liver cancer. However these tumor markers were occasionally positive and nonspecific in cancer-like lesions, implying no advantage for differential diagnosis between hepatocellular carcinoma and apparent cancer-like lesions. The above results demonstrate that AFP, CEA and KM01 are effective for differentiating hepatocellular carcinoma among various hepatic tumors.
