We herein evaluated 36 cases of combined hepatocellular and cholangiocarcinoma (cHCC-CC) (including 29 surgically resected and seven autopsy cases) by the immunohistochemical methods of anticytokeratin antibodies 7 and 19, and then analyzed the clinicopathologic features by comparing cHCC-CC with ordinary hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). The results indicated that even if mucin production could not be confirmed, nine cases with HCC areas that showed a histological resemblance to CC also showed immunohistological biliary differentiation. Therefore, we advocate that these HCC with biliary differentiation based on an immunohistochemical analysis should thus be included in the criteria of cHCC-CC in broad terms. Regardless of the extent of mucin production, the cHCC-CCs as indicated by an immunohistochemical analysis are considered to have a similar background to that of ordinary HCCs regarding such factors as the average age, male:female ratio, hepatitis B surface antigen (HBsAg) and hepatitis C virus antibody (HCVAb) positivity, alpha-fetoprotein level, and the presence of cirrhosis. However, cHCC-CCs tend to metastasize to many organs and the lymph nodes, and, as a result, have a poor prognosis.

Hepatic malignancy accounts for a large number of cancer-related deaths worldwide. Radiologic evaluation of the liver is critically important in the selection of patients for surgical treatment and newer modalities including computed tomographic arterial portography and intraoperative sonography show promise in the detection of small lesions. Advances in our understanding of the segmental anatomy of the liver, studies of intraoperative hepatic ischemia, and improved care of patients following major hepatic resections have extended the limits of surgical treatment of liver lesions, especially in cirrhotic patients with limited functional reserve. Along with hepatitis B, new data suggest that hepatitis C is also important as an agent causing hepatocellular carcinoma. In addition, the tumor suppressor gene p53 is frequently mutated in aflatoxin-induced hepatoma. In endemic regions, mass screening for early hepatocellular carcinoma appears to increase the surgical cure rate. Resectional surgery remains the best treatment for primary liver cancer and, in selected cases, liver transplantation is worthwhile. Liver resection for some patients with metastases of colorectal origin is now considered standard therapy and studies of regional chemotherapy for liver cancer are beginning to show promise. It remains to be seen whether adjuvant chemotherapy after liver resection will increase cure rates.

Hepatocellular carcinoma is one of the most common human cancers with an annual incidence of about 1,000,000 cases worldwide. Although hepatocellular carcinoma is predominant in hepatitis B virus endemic areas, it has also become a major problem in Europe, Japan and North America in close association with the increasing incidence of hepatitis C virus infection. The pathogenetic role of hepatitis C virus infection in the development of HBsAg-negative hepatocellular carcinoma needs to be clarified. In this paper the case of a 66-year-old HBsAg-negative and anti-HCV positive female who developed hepatocellular carcinoma in a cirrhotic liver is reported. After 1 year of follow up, urgent laparotomy had to be performed due to highly differentiated ovarian metastases of the hepatocellular carcinoma. Plus- and minus-stranded HCV-RNA was detected by reverse transcription and "nested" polymerase chain reaction in both the patient's serum and in the metastatic ovarian tissue.

Alpha-fetoprotein (AFP)-producing hepatoid adenocarcinoma of the stomach is a rare and recently discovered entity. We report an unusual combination of hepatocellular carcinoma and hepatoid adenocarcinoma of the stomach with multiple liver metastases. The patient, a 62-year-old Japanese man, was clinically diagnosed as having hepatocellular carcinoma because of the presence of liver tumors, a markedly elevated serum AFP level, and a positive hepatitis C virus (HCV) antibody titer. Autopsy revealed multiple tumors in the liver; one was a primary hepatocellular carcinoma without metastasis, and the others were metastases from latent hepatoid adenocarcinoma of the stomach. In the hepatocellular carcinoma, bile production was observed although the tumor was immunohistochemically negative for AFP. On the other hand, both the primary gastric and metastatic liver hepatoid adenocarcinomas were positive for AFP. Therefore, hepatoid adenocarcinoma of the stomach was responsible for the excessive production of AFP and was the cause of death.

Chronic inflammatory states frequently lead to the increased production of nitric oxide (NO) via inducible NO synthase (NOS-2). In addition, NO may produce mutagenesis through several mechanisms such as DNA oxidation, DNA deamination, and the formation of N-nitroso compounds. As there is a strong association between human hepatitis C virus (HCV) infection and the development of hepatocellular carcinoma (HCC), we were interested in whether human HCV hepatitis leads to induction of NOS-2 and if the mutation repair system of p53/p21 was upregulated. Reverse transcriptase-polymerase chain reaction (RT-PCR) for human NOS-2 message was performed on RNA samples from both liver biopsies and whole liver from HCV-positive and control patients (normal liver from hepatic resections for metastases). Immunohistochemistry (IHC) for p53 and Western blot analysis for p21 were also performed on the whole liver samples. From the liver biopsies, 60% of HCV-positive patients expressed NOS-2 by RT-PCR. Looking at the whole liver samples, 100% of the HCV-positive patients expressed NOS-2 vs 12.5% in the normal samples. p53 was not detected in either group but there was upregulation of p21 over baseline expression in a number of the HCV-positive patients. Human HCV hepatitis leads to consistent upregulation of hepatic NOS-2 message, but message is not predictably present in "normal" human liver. There is also induction of p21 in some patients with HCV hepatitis. Chronic expression of NO in HCV hepatitis may play a role in DNA mutagenesis and the development of HCC.

Little is known about the coincidence of hepatitis C virus infection (HCV) and non-Hodgkin's lymphoma, although there is an increased incidence of chronic HCV infection with cryoglobulinemia type II and, interestingly, low-grade non-Hodgkin's lymphoma (NHL) in a few patients. We therefore report on a 74-year-old white male with known chronic hepatitis C virus infection who was admitted to the clinic due to weight loss and pain in the right upper quadrant. Ultrasound examination was performed for suspected hepatocellular carcinoma since a lesion in the left lobe of the liver was seen. X-ray of the lungs showed a few scattered lesions, suggestive of metastases. The ultrasound-guided fine-needle puncture revealed a high-grade malignant B-cell NHL While alpha-fetoprotein was normal, both cryoglobulin type II and the polymerase chain reaction (PCR) for HCV were positive. After six cycles of chemotherapy consisting of CHOP, the patient showed complete remission over three years. Ultimately, he died due to a sudden myeloic blast crisis. In summary, we discuss the possible etiopathologic role of the hepatitis viruses in the occurrence of non-Hodgkin's lymphoma. As we and others showed that HCV infects peripheral mononuclear blood cells (PBML), the infected PBML not only may be a source for reinfection after orthotopic liver transplantation, but also could be the cause for transformation and monoclonal propagation of lymphomatous tissue.

A 38-year-old man, with hepatitis C and a history of intravenous drug use had hepatocellular carcinoma. Severe low back pain was the result not of metastases but of extramedullary hematopoiesis. This was not confirmed by biopsy but seemed unequivocal on magnetic resonance imaging.

Chronic hepatitis C and B are the main causes of hepatocellular carcinoma (HCC) worldwide. Little is known about the etiology of HCC in Germany which is regarded as a low-prevalence area for viral hepatitis C (HCV) and B (HBV). To assess the etiologic factors of HCC in Germany we have retrospectively analyzed the records of 100 consecutive patients with hepatocellular carcinoma in our clinic. HCC-patients with documented status on HCV/HBV-infection and daily alcohol intake (n = 55) had HCV antibodies in 53%, HBs-Ag in 20%, isolated chronic alcohol abuse in 11% and genetic hemochromatosis in 2%. In 13% of the HCC-patients no risk factor could be identified. Coinfections with HCV and HBV were not observed. Liver cirrhosis was present in 90% of the HCC-patients. In histologically confirmed HCC (n = 71) serum alpha-fetoprotein level was normal (< 8.5 ng/ml) in 20%, moderately elevated (8.5-300 ng/ml) in 48% and considerably elevated (> 300 ng/ml) in 32% of the patients. Only 31% of all patients presented with small single lesions (< or = 5 cm) without evidence for extrahepatic metastases or portal vein thrombosis. Only 30% of the HCC-patients could be treated with a curative intention (28 hepatic resections, one orthotopic liver transplantation). Patients who underwent resection had cumulative 6-month, 1-year, 2-year and 3-year survival rates of 83.8%, 65.9%, 54.3% and 24.8% respectively. Median survival time after resection was 24.8 months compared with 5.8 months in symptomatically treated patients with unresectable HCC (n = 39). Patients with hepatitis C-associated HCC were significantly older than patients with hepatitis B-associated HCC (mean values: 63.2 vs. 54.2 years). Frequency of cirrhosis, tumor stage, alpha-fetoprotein level and prognosis did not differ between groups. In conclusion hepatocellular carcinoma was predominantly associated with chronic HCV-infection. Most patients presented with normal or moderately elevated serum AFP-levels. Prognosis was poor even after hepatic resection.

The medical records of 267 patients who had liver tumors, primary and metastatic, from 1988 to 1995 were retrospectively reviewed. Two hundred thirteen patients (80%) had metastatic disease, and 54 patients (20%) had primary liver disease. Their clinical manifestations and laboratory values were evaluated as factors predictive of diagnosis and survival. There was a significant increase in the occurrence of upper abdominal pain, weight loss, extrahepatic symptoms due to the metastatic origin, and hepatomegaly. Metastases from colorectal primary lesions were synchronous in 34 patients and metachronous in 31 patients. Stomach, lung, and pancreatic primaries were more commonly synchronous. Breast metastases were more commonly metachronous. Elevated serum glutamic-oxaloecetic transaminase and alkaline phosphatase and decreased albumin were the most common liver test abnormalities at diagnosis. Carcinoembryonic antigen values were elevated in the majority of colon cancer patients. Eighty-one percent of patients with primary liver cancer had elevated levels of alpha-fetoprotein, 40 per cent were seropositive for hepatitis B, and 23 per cent were seropositive for hepatitis C. Seventy-nine patients (30%) underwent surgery for their cancer, 37 (47%) had resections, 38 (48%) were unresectable, and 4 (5%) underwent liver transplantation. The patients who underwent surgery had a 32 per cent 5-year survival rate compared to a 0 per cent 5-year survival in the patients who did not have surgery (p = 0.0001). The patients who had resections had a better survival rate than those deemed unresectable at surgery (62% versus 0% at 5-years with p = 0.0008). The perioperative morbidity rate was 16 per cent, with lobectomies having the best rate and trisegmentectomies having the worst. Perioperative mortality rate was zero for all liver resections. Hepatic resection and, in selected patients, liver transplantation are the only two available therapeutic modalities that produce long-term survival with a possible cure in patients with primary and metastatic liver tumor.

Radical hepatectomy was carried out on a patient with hepatocellular carcinoma (HCC) located in segment VIII of the liver. The patient was a 56-year-old man who showed positive for hepatitis C antibody and negative for hepatitis B surface antigen. Six months after hepatectomy, a lumbar plane X-ray and computed tomography examination revealed bone metastases in the lumbar vertebrae. The patient was subsequently treated by radiation to the lumbar vertebrae in response to lumbago. The metastatic lesion has been well controlled by radiotherapy on an outpatient basis with no recurrence for 5 years and 3 months. The prognosis of patients with HCC with distant metastases is poor. It is believed that the long survival of this patient can be attributed to successful radiotherapy of the bone metastasis after hepatectomy and the lack of recurrence in the liver.
