Hepatoblastoma (HB) rarely occurs in adults, and very few cases of successful resection have been documented. We report herein the unusual case of a 22-year-old, otherwise healthy woman with no history of liver disease who presented with upper abdominal pain and hepatomegaly. Tests for hepatitis B virus (HBV) and hepatitis C virus (HCV) were negative, but the AFP was mildly elevated at 77 ng/ml, the normal being < 20. There was no evidence of liver cirrhosis on either the laboratory or histologic examinations. A well-demarcated solid mass of 14 cm in diameter, which was lobulated and partly necrotic, was detected in the liver by computed tomography (CT). The lesion was echogenic on ultrasound, slightly hypodense on CT, and mildly hypervascular on arteriogram. The entire tumor was resected by extensive hepatectomy preserving only the lateral segment and part of the posterior segment of the liver. Histologically, the neoplasm was diagnosed as a pure epithelial HB of the fetal type. Following the operation, the patient has been well and free of recurrence for 38 months, maintaining low alpha-fetoprotein (AFP) levels at around 5 ng/ml. To our knowledge, this is the longest reported survival of an adult following surgical resection of an epithelial HB.

Familial and secondary deficiency of plasma lecithin-cholesterol acyltransferase (LCAT) produce circulating lipoprotein particles with gross structural and compositional abnormalities; these have adverse effects on a variety of cellular functions. Factors affecting hepatic synthesis and secretion of this plasma enzyme are largely unknown but, potentially, some of them can be investigated with monospecific antibodies. In the present study, enzymically active LCAT was purified 40,000-fold from human plasma and then used to raise polyclonal antibodies in New Zealand White rabbits. Addition of this antiserum (1 microliter) to human plasma (25 microlitres) completely inhibited LCAT activity, although it was less effective against plasma from other species. The antibodies appeared to be monospecific to plasma LCAT. They gave a single precipitin arc by crossed immunoelectrophoresis, while immunodiffusion established that there was no cross-reactivity with several apolipoproteins or with serum albumin. Moreover, the antiserum was successfully used to detect LCAT in normal human plasma by Laurell rocket immunoelectrophoresis. By contrast, Western blotting of plasma proteins using whole LCAT antiserum was largely unsuccessful because of high background staining, although this could be substantially reduced by use of an IgG fraction. However, the whole antiserum readily immunoprecipitated LCAT secreted into the culture medium of HepG2 cells, a human hepatoblastoma cell line, pre-labelled with [35S]methionine, the [35S]-labelled LCAT appearing as a narrow 65-kDa protein band by electrophoresis and fluorography. We conclude that polyclonal antibodies may be an important tool to investigate the characteristics and underlying mechanisms of secondary LCAT deficiencies, including those associated with hepatic cirrhosis and schistosomiasis.

The enthusiasm to treat or even cure patients with unresectable hepatobiliary malignancy by total hepatectomy and liver transplantation has considerably diminished. Nowadays, due to organ-donor shortage, patients have to be selected with predictable likelihood for long-term survival. According to own experience and a review of the literature, liver transplantation may be considered in unresectable early stage hepatocellular and proximal bile duct carcinoma, the uncommon entities fibrolamellar carcinoma, epithelioid haemangioendothelioma and hepatoblastoma as well as in liver metastases from neuroendocrine tumours. At present, advanced stages of hepatocellular and proximal bile duct carcinoma, as well as intrahepatic bile duct carcinoma, haemangiosarcoma and metastases from nonendocrine tumours, should be excluded from transplantation. In order to cure the cancer-bearing disease, liver transplantation might be the ideal treatment for small but still resectable hepatocellular carcinoma with underlying cirrhosis. Our retrospective comparison of survival after resection and transplantation for early stage hepatocellular carcinoma does not reveal a significant difference. Although a tendency has been observed in favour of transplantation, resection of these tumours is still justifiable, not least because of donor organ shortage.

Alpha-feto protein (AFP) is a clinically useful marker for hepatocellular carcinoma, hepatoblastoma, and nonseminomatous testicular tumors. Elevated serum AFP can also occur with tumors of the gastrointestinal tract, pancreas, lung, kidney, and urachus. Serum AFP can also be minimally elevated in nonmalignant conditions including acute and chronic hepatitis, cirrhosis, and pregnancy. Reports of gallbladder carcinoma that elaborate AFP are extremely rare, and almost all represent papillary carcinomas. Until now, there have been only two reports in the world literature that describe undifferentiated gallbladder carcinoma with elevated serum AFP. The authors present one case of undifferentiated gallbladder carcinoma and another case of poorly differentiated gallbladder carcinoma with increased serum AFP. In both cases, serum AFP was particularly useful in documenting metastatic recurrence of gallbladder carcinoma.

PURPOSE: The indication for liver transplantation in malignant liver tumors has been controversial due to disappointing results and shortage of donor organs. The authors evaluated the experience and results of a single center in order to define present indications and selection criteria in hepatobiliary malignancy. PATIENTS AND METHODS: Retrospective analysis of 212 patients who underwent liver transplantation for malignant tumors between 1972 and 1995: Primary hepatobiliary tumors: hepatocellular carcinoma, n = 124 (with underlying cirrhosis, n = 86; fibrolamellar subtype, n = 8); intrahepatic bile duct (cholangiocellular) carcinoma, n = 24; proximal bile duct carcinoma, n = 29; other uncommon entities (n = 15); secondary liver tumors: neuroendocrine, n = 11, and nonendocrine, n = 9. RESULTS: Survival rates in primary liver cancer were correlated to International Union Against Cancer (UICC) tumor stage. For hepatocellular and proximal bile duct carcinoma significantly better outcome was found in UICC-tumor stage I and II versus III and IV. No long-term survival was found after transplantation for intrahepatic bile duct carcinoma, hemangiosarcoma and nonendocrine liver metastases. Comparison of transplant and resected patients with hepatocellular carcinoma stage I and II with underlying cirrhosis showed better survival after transplantation: 1-, 3-, 5-year survival rate of 83.3% versus 76.9%, 75.8% versus 44.0%, 60.6% versus 44.0%, and median survival 96.5 versus 23.2 months. Although this difference was not significant, no patient died from tumor recurrence in the transplant group versus three in the resection group. DISCUSSION AND CONCLUSIONS: Patients with malignant tumors can be selected for transplantation with predictable likelihood for long-term survival. According to the present data, liver transplantation can be considered in unresectable UICC-stage II hepatocellular and proximal bile duct carcinoma, the uncommon entities fibrolamellar carcinoma, epitheliod hemangioendothelioma and hepatoblastoma as well as liver metastases from neuroendocrine tumors. UICC-stage II and IV hepatocellular carcinoma as well as intrahepatic bile duct carcinoma, hemangiosarcoma and metastases from nonendocrine tumors should be excluded from transplantation alone. For hepatocellular carcinoma, multimodality treatment protocols have had a proven impact on the prevention of early recurrence and prolongation of survival. There is evidence that liver transplantation in still resectable hepatocellular carcinoma with underlying cirrhosis might be more appropriate in order to cure the cancer-bearing disease.

The authors report 3 cases of liver transplantations in children between 4 and 10 years of age, complicated with malignant hepatic tumors after biliary atresia. The preoperative abdominal computed tomography (CT) scans of all 3 cases showed hepatic masses. The serum alpha-fetoprotein levels were elevated highly in 2 cases. After living-related liver transplantation (LRLT), the pathologic findings of the masses in the resected livers showed hepatocellular carcinoma in 2 cases and hepatoblastoma in the other. All cases were associated with biliary cirrhosis. The stage of the liver tumor in the 3 cases using the TNM system was IVA (T4, N0, M0), II (T2, N0, M0) and IVA (T4, N0, M0). Chemotherapy was used in all cases after liver transplantation, and all patients survived with no recurrence. The results suggest that even though malignant liver tumors rarely are complicated with biliary atresia in childhood, one should be alert to the occurrence of hepatic malignancy and perform routine screening of alpha-fetoprotein levels, abdominal CT scans, and magnetic resonance imagings.

Liver transplantation (LT) for malignant tumors should be accepted if, with adequate case selection, long-term results are similar to those in patients transplanted for benign diseases. The aim of the present study was to reexamine selection criteria for LT in malignant diseases with particular emphasis on hepatocellular carcinoma (HCC) in cirrhosis. One hundred-three of 369 patients transplanted in our unit had HCC in cirrhosis (28%), 15 of which were incidental tumors, and 234 patients underwent LT for non-cholestatic cirrhosis. Pretransplant arterial chemoembolization(TACE) was performed in 36 cases (41%) of known HCC. Only early,well-delimited tumors in advanced cirrhosis with no extrahepatic disease were accepted for LT. Hepatocellular carcinoma characteristics included mean tumor size (3.1 cm), multiple (59%), bilobular involvement (31%), and vascular invasion (9.2%). Postoperative mortality was 4%. Median follow-up was 67.5 months. Tumor recurrence rate was 14.5%, 33% (5/15) in incidental tumors and 11.4% (10/88) in known HCC and by tumor stage (pTNM): 7.7% (1/13) in stage I, 16.7%(5/30) in stage II, 15% (3/20) in stage III, and 17% (6/35) in stage IV. Mean time for recurrence was 20.6 months. Tumoral vascular invasion, tumor differentiation, and satellite tumors were significant factors for tumor recurrence in univariate analysis, whereas tumor vascular invasion was the only significant factor for tumor recurrence in multivariate analysis. Actuarial survival rates at 1, 3, and 5 years were 81%, 66%, 58%, respectively, in patients with HCC and were similar to those of cirrhotic patients 76%, 67%, 63%, respectively. In conclusion, patients with early HCC in cirrhosis are good candidates for LT; results are similar when compared with those of cirrhotic patients without tumor. Liver transplantation for other malignancies is admitted only in fibrolamellar hepatoma, hepatoblastoma, epithelioid hemangioendothelioma without extrahepatic disease, and in metastases from carcinoid tumors.

Birth weight is a popular topic, because it is precisely recorded, a major determinant of infant survival, associated with infant mortality, and health outcomes later in life. Low birth weight (LBW) is a predisposing factor for metabolic abnormalities such as atherosclerosis, renal disease, non-insulin diabetes mellitus, asthma, low IQ, hypertension, obesity, psychological distress. They have all been reported to be more common among those who were small at birth. Due to lack of studies suggesting a linkage between LBW and diseases of liver; evidences, which support the hypothesis on the creation of a link between LBW, an indicator of unfavourable intrauterine environment, and liver diseases emerging in the adult life, and possible direct associations of LBW with liver diseases, e.g., hepatitis, non-alcoholic fatty liver disease, cirrhosis, hepatoblastoma, or hepatocellular carcinoma were discussed. The associations between LBW and hepatitis vaccination as well as paediatric parental nutrition were also noted.

Liver transplantation (LT) has been utilized in the treatment of primary hepatic malignancy for decades. Hepatocellular cancer (HCC) remains the most common malignant condition treated with LT, with almost 400 such transplants performed annually in the US. Refinement in the selection criteria for LT in patients with HCC has led to survival rates similar to those for LT in nonmalignant conditions. Excellent results have also been reported following LT for select patients with epithelioid hemangioendothelioma and hepatoblastoma. Patients with cholangiocarcinoma treated with LT have generally faired poorly, with survival rates far below that of LT for nonmalignant conditions. Improved survival has recently been reported following LT for cholangiocarcinoma in highly select patients treated with aggressive neoadjuvant therapy. The future utility of LT in the treatment of malignancy will be influenced by several factors, including a profound organ donor shortage faced worldwide; increasing prevalence of hepatitis C, HCC and cirrhosis; and the evolution of live donor liver transplantation.

Expression profiling of hepatocellular carcinoma has demonstrated that glypican 3 (GPC3), a heparan sulfate proteoglycan anchored to the membrane, is expressed at a markedly elevated level in hepatocellular carcinoma. In this paper, two monoclonal antibodies against GPC3, GPC3-C02 and A1836A, were confirmed to specifically recognize GPC3 molecule in cells from hepatocellular carcinoma and hepatoblastoma cell lines by immunoblotting, and both were confirmed to recognize different epitopes of the GPC3 molecule by epitope mapping. Then, we evaluated the feasibility of GPC3-immunohistochemistry in the pathological diagnosis of benign and malignant hepatocellular lesions by applying these monoclonal antibodies to formalin-fixed and paraffin-embedded specimens. The immunoreactivity turned out to be identical in the two monoclonal antibodies and was thus confirmed to represent the actual expression of the GPC3 molecule. The expression was observed in the fetal liver, but not in normal adult liver, liver cirrhosis or hepatitis except for a tiny focus of a regenerative nodule of fulminant hepatitis. Diffusely positive staining of GPC3 was observed in malignant hepatocytes in hepatoblastomas and in hepatocellular carcinomas (47/56, 84%). GPC3 expression was independent of the differentiation and size of the hepatocellular carcinoma. On the other hand, there was only weak and focal staining in low-grade (2/8) and high-grade dysplastic nodules (6/8). GPC3 immunoreactivity was detected in only one of 23 metastatic lesions of colorectal carcinoma, and its expression was entirely absent in the liver cell adenoma (0/7), carcinoid tumor (0/1), and cholangiocellular carcinoma (0/16). When compared with immunohistochemistry of hepatocyte antigen and alpha-fetoprotein, GPC3-immunohistochemistry was significantly much more specific and sensitive for hepatocellular carcinomas. Thus, GPC3 was confirmed to be one of the oncofetal proteins now attracting attention for their promise both as markers of hepatocellular carcinoma in routine histological examination and as targets in monoclonal antibody-based hepatocellular carcinoma therapy.
