Sixty-six patients surviving over 5 years after resection of hepatocellular carcinoma (HCC) are investigated. Of them, subclinical stage amounted to 56.1% (37/66) and moderate stage to 43.9% (29/66). There were 35 cases with small HCC (less than or equal to 5 cm). Cirrhosis was present in 81.1% (54/66). Radical resection was performed in 98.5% (65/66) and palliative resection in 1.5% (1/66). Reoperation for subclinical recurrence and solitary pulmonary metastasis was done in 14 patients, and sequential resection of huge tumors, in three patients. By the end of June 1988, follow-up varied from 60 to 319 months (mean, 115 months); 80.3% of the patients (53/66) are still alive and free of disease; 19.7% (13/66) died with disease. The majority of long-term survivors have returned to their original work; some young patients got married after resection of small HCC 10 years ago, and some can even play football again. Some aspects to improve long-term survival are discussed.

Members of the hepadnavirus family share properties of virion structure, genome structure and replication, epidemiologic behavior, and pathogenic effects. Persistent infections with hepatitis B virus (HBV) in man, woodchuck hepatitis virus (WHV) in Marmota monax, ground squirrel hepatitis virus (GSHV) in Spermophilus beecheyi, and duck hepatitis B virus (DHBV) in domestic ducks of China are associated with development of hepatocellular carcinoma (HCC). Epidemiological evidence implicating hepadnavirus infection in HCC includes the observation that the geographic distributions of HBV infection and HCC are similar, that the incidence of HCC is much higher in hepadnavirus-infected than uninfected hosts, and that viral DNA sequences are integrated in the cellular DNA of most (e.g., 80 to 90%), but not all, hepadnavirus-associated HCC. Cirrhosis further increases the risk of HCC in HBV-infected humans. The precise role of hepadnaviruses in development of most HCC is unclear, although the finding of viral integrations within or near protooncogenes in a few cases suggests the possibility that these integrations may play a direct role in these HCC. However, in the great majority of HCC, viral integrations are in different cellular DNA sites in different HCC, integrations are not within domains of known protooncogenes, and integrations are not found in some 10 to 15% hepadnavirus-associated HCC, suggesting that persisting viral sequences are not directly involved in the development of these HCC as viral sequences are for tumors caused by viruses with oncogenes or viruses that act by a "promoter-insertion" mechanism.(ABSTRACT TRUNCATED AT 250 WORDS)

We have examined the clinical, prognostic, aetiological and pathological features of 41 consecutive British patients with hepatocellular carcinoma (HCC). Presenting symptoms were often vague, and patients were generally in poor condition at diagnosis, 56% being of WHO grade 2 performance score or higher. Ascites (46%) and jaundice (35%) were often present at diagnosis, and the median duration of survival from diagnosis was only 6 weeks. Only initial performance grade (p less than 0.0001) and serum bilirubin concentration (p = 0.02) significantly affected prognosis. Serum alphafoetoprotein (AFP) was positive by counter-immune electrophoresis in only 34%, but increased to 68% when radioimmunoassay was used. Cirrhosis was present in 33 patients (80%) and was most often cryptogenic (12) or alcoholic (7) in origin. Serum HBsAg was detected in 5 patients (12%) and, of the remainder tested, 21% had serological evidence of past HBV exposure. None of 8 serum HBsAg-negative tumour specimens had detectable HBV-DNA integration into the tumour cell genome. Liver-cell dysplasia was noted in 56% of patients with liver biopsies predating the diagnosis of HCC, and in 78% of biopsies taken at the time of HCC diagnosis. The commonest histological pattern was trabecular (71%). Other forms were rare; the fibrolamellar pattern was only seen in 2 patients.

The frequency of liver cell carcinomas (n = 249) in autopsies of adults (n = 36,074) from 1960 to 1981 was 0.69%; in males (n = 19,124) 1% (n = 192) and in females (n = 17,950) 0.34% (n = 57). The development of liver cell carcinoma was associated with cirrhosis of the liver in 87% of the cases (89% in males and 70% in females). The relative frequency of liver cell carcinoma in autopsies is increasing: 1960 to 1966 0.5%, 1967 to 1973 0.89%, 1974 to 1981 1.4%. This increase is mainly the result of the development of carcinoma after cirrhosis in males: 1960 to 1966 0.49%, 1967 to 1973 0.86% and 1974 to 1981 1.2%. Cirrhosis of the liver from 1974 to 1981 showed a continuous increase in the relative frequency and an age-shift towards younger age groups in males. Throughout the study period a history of alcohol abuse was frequently given in the patients history.

From October 1982 to June 1985 158 hospitalized patients in the National Hospital of Niamey, Republic of Niger, were selected whenever one of the following signs was found: hepatomegaly, jaundice, ascites, oesophageal varices, abdominal venous pattern, or splenomegaly. Investigations included hepatic echography (158/158), needle liver biopsy (68/158), radioimmunoassays for serum hepatitis B surface antigen (HBsAg; 158/158), anti-HBs (152/158), anti-HBc (129/158) and anti-delta antibody (anti-HD; 158/158). 112 patients with liver diseases comprised 28 with chronic hepatitis, 55 with non-alcoholic hepatic cirrhosis, and 29 with hepatocellular carcinoma (HCC). 46 patients with other diagnoses were used as controls. 71/112 liver disease patients were positive for HBsAg in serum compared with 1/46 controls (P less than 10(-9)). Prevalences of delta superinfection in patients with serum HBsAg (+) and anti-HD (+) were 45/112 (40.2%) in liver disease patients versus 1/46 (2.2%) in controls (P less than 10(-9)). Delta superinfection was very frequent in chronic hepatitis (8/28), non-alcoholic cirrhosis (24/55) and HCC (14/29). In chronic hepatitis, delta superinfection was more frequent in the chronic active form than in the chronic persistent type (not significant). Cirrhosis patients with delta superinfection were younger (10 years in males, 11 years in females) than those without (P less than 0.05).

Eleven cases of hepatocellular carcinoma (HCC) in childhood were investigated by immunohistochemistry for association with hepatitis B virus (HBV) infection. Seven of 11 cases (64%) demonstrated positivity for hepatitis B surface antigen (HBsAG), whereas all 11 were negative for hepatitis B core antigen (HBcAG). Cirrhosis was absent in all cases, and other causes for HCC in childhood were not found. All children with HBV-associated HCC died within 6 months of diagnosis. The median survival time of these children was 2 months. Only one child with HCC of trabecular subtype without HBV association is still living after 18 months. However, this child has metastases and a local recurrence. Three other children with HCC of fibrolamellar subtype are free of disease after 2, 5, and 6 years, respectively. The high number of cases of HBV-associated HCC shows the important role of HBV infection as an etiologic factor for the development of childhood HCC in middle Europe.

The water-jet method has been used during hepatic resection. The instrument cuts the hepatic tissue with the high pressure of the fine water flow, while the exposed elastic intrahepatic vessels are spared injury. A comparative study on the water-jet method with the previously employed conventional methods was undertaken. Hepatic resections were performed on 35 patients using the water-jet method. Cirrhosis of the liver was associated with 10 of the 24 patients with hepatocellular carcinoma. An ordinary saline solution was used as the jet, which was projected at a pressure of between 12 kg/cm2 and 20 kg/cm2 through a 0.15/mm-diameter nozzle. A higher jet pressure was needed to cut the fibrotic hepatic parenchyma. In the case of normal liver, the intrahepatic vessels of more than 0.2 mm were well preserved. In most of the cases, the loss of blood when cutting the hepatic parenchyma can be easily reduced with a jet pressure of 15-16 kg/cm2, thus preserving the fine vessels more than 0.2 mm in diameter without injury. When the same pressure was applied in the cutting of a cirrhotic liver, it took much longer time compared to that of a non-cirrhotic normal liver parenchyma. The cut surface was smooth compared to that after using CUSA, although its disadvantages lie in the formation of air bubbles, which obscure the operative field. The controlled projection of a jet of water under optimal pressure may ensure a safe hepatic resection of both normal and cirrhotic livers. Furthermore, because of its uncomplicated form, a wide range of applications can be expected, while the lower cost will also expedite its large-scale use for economic reasons.

The authors report the clinical and biological features in 197 patients with hepatocellular carcinoma seen in two French hospitals. Mean age was 63 +/- 12 years. Eighty-nine per cent were men. Cirrhosis was present in 88 p. 100. Alcoholic liver disease was associated with hepatocellular carcinoma in 71.5 p. 100. At the time of diagnosis, ascites was present in 62 p. 100 of the patients, jaundice in 49 p. 100, encephalopathy in 20 p. 100 and gastrointestinal bleeding in 12.5 p. 100. Twenty patients (10 p. 100) did not have any of these complications. An increase in serum gammaglutamyl transpeptidase and ASAT was the most frequent biological abnormality observed in 96 and 94 p. 100 of patients respectively. Hypercalcemia and a high hematocrit were present in 5 and 6 p. 100 of patients respectively. Serum HBs Ag (RIA) was present in 17.5 p. 100 of patients, anti-HBc in 50 p. 100 and anti-HBs in 33.5 p. 100; 38.5 p. 100 of patients had no serum HBV marker. Serum alphafetoprotein levels were higher than 20 ng/ml, 250 ng/ml and 1,000 ng/ml in 76.5 p. 100, 43.5 p. 100 and 33 p. 100 of patients respectively. There were no relationships between the presence of serum markers of HBV or high alphafetoprotein levels and clinical and biological data. These results confirm that the clinical, biological and virological aspects of hepatocellular carcinoma in France are similar to those reported in other western countries.

Estrogen receptors (ER) were assayed on hepatocellular carcinoma (HCC) and surrounding liver tissue in 30 adult patients. All specimens were obtained at the time of surgery. Cirrhosis of the liver was associated with 28 patients and chronic hepatitis in 2 patients. ERs were detected in 12 of 30 HCCs. The value ranged from 1.4 to 9.2 fmol/mg cytosol protein with the dissociation constant (Kd) value less than 1 nanomol. On the other hand, 13 of 28 cirrhotic livers had measurable amounts of the receptors that ranged from 1.5 to 4.1 fmol/mg cytosol protein. Two livers with chronic hepatitis did not have detectable amounts of ERs. The receptors were not detected in both the tumor and liver in ten patients. The ER titers in HCC did not have any correlation with serum levels of alpha-fetoprotein or carcinoembryonic antigen, hepatitis B virus profiles, and histologic types of the tumor. In the light of the current results, it would be of great interest whether hormone therapy can be used or not as a treatment of naturally occurring HCC in humans.

From January 1, 1975 to July 1, 1984, 37 patients with a tentative diagnosis of hepatocarcinoma on cirrhosis were operated upon. There were 34 men and 3 women, aged from 32 to 82 years (mean: 60 years). The diagnosis of cirrhosis rested either on a history of liver failure associated with clinical and biochemical signs of hepatocellular dysfunction (4 cases), or on a positive liver biopsy (5 cases). In 20 cases the diagnosis was suspected on account of abnormal liver function tests, but in 8 patients it was revealed by macroscopic examination of the liver during surgery. Cirrhosis was attributed to chronic alcoholism in 25 cases, haemochromatosis in 11 cases and positive HBs antigen in 7 cases. The diagnosis of hepatocarcinoma, suggested by altered general condition or recent pain, rested on the finding of a tumoral image at scintigraphy (16 cases), ultrasonography (19 cases), computed tomography (7 cases), arteriography (17 cases) or laparoscopy (7 cases). In only 7/32 patients was the alpha-foetoprotein level higher than 500 ng/l. Surgery confirmed the diagnosis of hepatocarcinoma in every case but that of cirrhosis in only 14/37 cases; 10 patients had lesion of hepatic fibrosis and 1 had regenerative nodular hyperplasia. In 10 cases no accurate histological diagnosis could be made since the liver tissue sample had been taken too close to the tumour. The finding of normal liver tissue shows that one should not refrain from operating merely because the diagnosis of cirrhosis rests on clinical grounds. Since 1979, surgical treatment consists in an attempt to excise the tumour. Per-operative mortality is the same with excision surgery (21%) as with exploratory or palliative surgery (17%). Fourteen excisions were performed (i.e. aresectability rate of 38% for the series): 2 liver transplantations, 2 right hepatectomies, 2 left hepatectomies, 2 left lobectomies, 2 bisegmentectomies and 3 tumorectomies. The survival rate of 2 years was 27%, as opposed to 5% with exploratory or palliative surgery. Systematic monitoring of cirrhosis with ultrasonography should result in early diagnosis of hepatocarcinoma at a stage where limited hepatic excision is possible and the chances of surviving are highest.
