To study the relationship between duck hepatitis B virus (DHBV) infection and duck hepatocellular carcinoma (DHCC), histological examination and DHBV DNA hybridization were performed in 875 ducks from three flocks in Qidong County. Among them, 34 suffered from hepatoma, including 23 hepatocellular carcinoma, 8 cholangiocarcinoma and 3 hepatocellular-cholangiocarcinoma. Of the 34 ducks with hepatoma 27 were positive for DHBV DNA in the liver and/or serum. DHBV DNA was demonstrated in neoplastic nodules of 22 ducks. Southern blot analysis showed that 13 cases were of the integrated pattern of DHBV DNA in neoplastic nodules. The paratumor tissues of 14 ducks with massive tumor were analysed at the same time. Five cases showed integrated pattern, 4 cases free pattern and the other 4 cases both integration and free pattern of DHBV DNA. The hybridization pattern of DHBV DNA in tumor nodule was different from that in paratumor regions in 11 cases and identical in 3 cases. DHBV antigen was positive in 13 tumor nodules and 21 paratumor tissues in the 34 ducks with hepatic tumor by both victoria blue and orcein stain methods. Advanced liver diseases were found in 30 out of the 34 ducks with hepatoma, including 12 cirrhosis and 18 chronic active hepatitis. In southern blot analysis of 122 DHBV DNA positive Qidong ducks without hepatoma, only free pattern of DHBV was seen, while 44 control ducks from Changchun were negative for DHBV DNA. Neither hepatic tumor nor liver diseases were seen in the control ducks. The results suggest that hepatocellular carcinoma in ducks is similar to that in human HCC. They have a high frequency of viral DNA integrated into the host genome and a liver disease background.

A 61-year-old male was admitted because of hemoptysis. He had a 9 year history of liver cirrhosis associated with HB viral chronic hepatitis. Physical examination revealed no abnormalities. Laboratory investigations revealed positive HBs antigen with normal alpha-fetoprotein. Chest X-ray film showed large mediastinal lymph nodes and an endobronchial polypoid mass in the distal end of the right main bronchus. The right main PA was narrowed due to compression by the mediastinal mass. Bronchoscopic examination revealed a polypoid mass in the right main bronchus. The biopsy specimen was histologically diagnosed as undifferentiated large cell carcinoma. The patient developed respiratory failure, and died 3 weeks after admission. Autopsy revealed a small liver cancer of 1.3 cm diameter within the cirrhotic liver, associated with a small abdominal lymph node metastasis and large mediastinal lymph node swellings. Thromboembolism in the bilateral main pulmonary arteries was concluded to be the cause of death. The mediastinal mass which directly invaded into the right main bronchus had a close histological similarity with the liver cancer, showing undifferentiated carcinoma cells with bizarre nuclei and abundant cytoplasm. An immunohistological study revealed cells positive for alpha-fetoprotein in the mediastinal lymph nodes. The patient was diagnosed as having small liver cancer with mediastinal lymph node metastases. A survey of the literature revealed only a few cases of advanced hepatoma associated with prominent mediastinal metastases. This is the first reported case of small liver cancer presenting with large mediastinal lymph node metastases.

Epidemiological, clinical and laboratory data point to a role of hepatitis C virus infection in hepatocellular carcinoma. The connection appears to be indirect and to be mediated by cirrhosis. Thus, geographical differences can be observed, based on the locally prevalent etiological factors for cirrhosis. In the end, prospective studies of hepatitis C virus infected persons will be needed to elucidate the role of this agent in liver cancer.

Chronic infection by hepatitis B and C viruses is frequently associated to the development of primary liver cancer. Liver cirrhosis, induced by these viral infection, plays an important role in the liver carcinogenesis. In addition, HBV has a direct role in liver cell transformation by a transactivating effect of some viral proteins as well as insertional mutagenesis. The role of hepatitis C virus is not known. The strong association, even in France, of primary liver cancer to these viral infections underline the importance of their prevention by vaccination.

The present paper reviews several studies performed between 1977 and 1986 in Singapore on the 10-year survival outcome of treatment for stage I and II hepatocellular carcinoma (HCC). Of 801 HCC patients evaluated, only 2 survivors (0.3%) remained in complete remission for 13 and 14 years, respectively. One had received four weekly cycles of prednisolone, Adriamycin, vincristine and 5-fluorouracil for an inoperable HCC with a 10-cm diameter, and the other had received localised synchronised hepatic irradiation and Adriamycin. As follow-up, the use of localised hepatic irradiation consisting of 131I-labeled (30 mCi) iodised oil in lipiodol infused via the hepatic artery appeared to benefit patients with small residual tumours but did not affect larger tumours measuring 2 cm in diameter. Prophylactic, intermittent long-term administration of lymphoblastoid interferon-alpha (Wellferon) was carried out in pre-cancerous, high-risk hepatitis B surface antigen (HBsAg)-positive patients with cirrhosis, in immediate male relatives of liver cancer patients, and in persons who had undergone hepatic resection. In the untreated group, 10/162 (6%) cirrhotics, 3/18 (17%) male family members, and 6/10 (60%) post-resection cases developed single or multiple HCCs within 1 year of screening done at 3-month intervals on the basis of alpha-fetoprotein (AFP) levels and real-time hepatic ultrasonography. In contrast, none of the Wellferon-treated group consisting of 518 cirrhotic patients, 82 male relatives of HCC patients and 20 post-resection cases developed HCC. Two HBsAg-positive individuals who had not been treated with interferon (IFN) developed hepatic nodules which that showed dysplasia, AFP elevation and chromosomal changes. These studies demonstrate the poor results of late diagnosis and show that early intervention and prophylaxis with Wellferon can reduce the incidence of HCC in high-risk persons. In addition, transhepatic chemoembolisation and liver resection are suitable methods for treating small HCCs (single or multiple) that are detected by screening. However, some of these early-detected HCCs remain highly malignant. Prophylactic treatment of pre-cancerous conditions appears to be a better option as a long-term programme for HCC.

We studied all the 70 cases of liver cancer referred to us in 1988. Sixty (85.71%) were primary hepatocellular carcinoma (HCC), the other 10 (14.29%) were metastatic liver cancer. Of the 60 HCC, 48 were males and 12 females. Peak age incidence was between 20-40 years. Forty-five (75%) had tumours in both lobes. Of the remaining 15, seven had tumours in the right lobe while eight were in the left. More detailed assessment identified eight as Child's C. Seven (11.66%) had laparotomy, and two were inoperable. Three (60%) died shortly after resection, leaving two survivors. One of the survivors lived for 24 months, and the other had recurrent tumour after 26 months. The majority had cirrhosis of the liver, were positive for markers of hepatitis B virus, and showed elevated serum alpha fetoprotein (AFP). Palliative treatment was disappointing, and all were dead within 15 months. Prognosis of HCC in our environment is poor. Considering the advances made in liver surgery in recent years, our mortality and morbidity figures can improve. Notwithstanding, preventive measures should be intensified.

Point-mutational activation of the c-Ki-ras proto-oncogene has been shown to be rare in human hepatocellular carcinoma, the most common primary liver cancer and one usually associated with chronic viral infection. To reveal the association of c-Ki-ras activation with cholangiocarcinogenesis under different etiological backgrounds, the incidence of point mutation at codons 12 and 13 of the c-Ki-ras proto-oncogene was examined in three groups of human liver cancers with differentiation to biliary epithelial cells: Group 1, cholangiocellular carcinoma in Japanese with normal livers; Group 2, cholangiocellular carcinoma in Thais who had lived in an area where the liver fluke Opisthorchis viverrini is endemic; and Group 3, combined hepatocellular-cholangiocellular carcinoma, a rare type showing features of both hepatocellular and biliary epithelial differentiation, in Japanese with chronic viral hepatitis with or without cirrhosis. The polymerase chain reaction and direct sequencing of its product were used to detect the mutation. Point mutation at codon 12 of the c-Ki-ras gene was detected in five (56%) of nine cases in Group 1. In contrast, the mutation was not detected in any of the cases in Groups 2 and 3. Therefore, point-mutational activation of c-Ki-ras did not seem to be involved in the development of primary liver cancers associated with apparent chronic irritation of liver cells or biliary epithelial cells caused by exogenous liver-fluke or viral infection. On the other hand, point-mutational activation of the c-Ki-ras proto-oncogene may be involved in cholangiocarcinogenesis in liver without preexisting liver-fluke or viral infection.

From november 1973 to June 1991, cryosurgery with liquid nitrogen was performed on 87 patients with primary liver cancer (PLC). Of these, 27 patients was of stage I (31.0%), 52 in stage II (59.8%), and 8 stage III (9.2%). There were 30 patients with PLC of < or = 5 cm (34.5%). Liver cirrhosis was found in 73 patients (83.9%). In the beginning, plate-like cryoprobes and thermocouples were used to monitor the frozen area. Later on we designed single- and multiple-needle cryoprobes for freezing tumors deeply into the hepatic parenchyma and intraoperative ultrasound was used to monitor hepatic cryolesions. The 1-year, 3-year, and 5-year survival rates were 60.5%, 32.0%, and 20.2%, respectively. Among the 30 patients with PLC of < or = 5 cm, the 1-year, 3-year, and 5-year survival rates were 92.6%, 66.6%, and 50.8%, respectively. There were no operative mortality and complications such as rupture of the tumor, delayed bleeding, and bile leakage. These results indicate that cryosurgery is a safe and effective local treatment for unresectable PLC.

This paper reports the application of Cox regression model in prognostic factors analysis of Primary Hepatocellular Carcinoma (PHC), based on the data obtained from 1618 registered of cases PHC and 432 hospitalized patients of PHC in ZhongShan City from 1980 to 1989. The result shows that there is an association between PHC and the following factors: extrahepato metastasis, therapeutic method, clinical stage, alpha-fetoprotein, gamma-glutamyl-transpeptidase, the number of tumors in the liver, the size of the tumor, icteric index and history of cirrhosis. Among these factors, clinical stage III, large liver cancer are unfavorable factors for PHC prognosis, while hepatectomy, hepatic artery catheterization chemotherapy, are favorable prognostic factors.

70 hepatic resections were performed using 2450 MHz microwave scalpel. Primary diseased included hepatocellular carcinoma (46 cases), hemangioma (18), hepatobiliary tract stone (2), biliary cystadenoma (1), inflammatory pseudotumor of the live (1), metastatic liver cancer (2). Hemostasis was excellent despite liver cirrhosis in all cases. The average amount of blood loss and blood transfusion was 249 ml and 294 ml respectively. Blood transfusion was not necessary in 30 patients. All cases were free from postoperative bleeding from the liver stump and abdominal infection. No complications attributable to microwave coagulation were noted. We conclude that this new operative technique can be used safely and easily in the field of hepatic surgery.
