We have carried out a prospective survey of 28 primary liver carcinomas over one year.
Hepatocellular carcinoma
is the commonest malignancy seen in Rhodesian blacks, which results in a high index of suspicion and accounts for the 96.4% positive diagnosis before death in this study. The age distribution was evenly spread through adult life with no definite peak incidence. Some were young and without evidence of chronic liver disease, but many had the stigmata of established hepatic disease. This contrasts with the common assertion that in areas of high incidence for primary liver cancer those affected are mainly young and lack signs of chronic liver disease. The commonest presenting symptoms were abdominal pain and swelling and weight loss. Hepatomegaly, often tender and nodular, was present in all but one. The incidence of alpha-feto protein, 46.5%, is low compared with other countries where primary liver cancer is common. Hepatitis B antigen was absent in all 28, suggesting that there is no association between the persistence of the antigen and hepatocellular carcinoma in Rhodesia. Liver function tests, although abnormal, were never diagnostic of primary liver cancer. We have confirmed the association of high alcohol consumption and
cirrhosis
with hepatocellular carcinoma.

A review of liver biopsies over a three year period revealed 166 cases of carcinoma of the liver.
Hepatocellular carcinoma
constituted the commonest malignant tumour in male Zambians. The different histologic sub-types were studied and compared wth a study of liver cell cancer in Uganda. Trabecular carcinoma was the commonest histological type. A significant association of hepatocellular carcinoma with macronodular
cirrhosis
was noted.

A survey of significant pathological abnormalities of liver in the first two decades of life is presented; this is based on biopsy and autopsy specimens received in the histopathology service in Nairobi over five years. It includes conditions which one might expect in a diagnostic service in any country, some of which are attributable to known local conditions, and others which show distinctive features in their occurrence of frequency. There is an unexpected number of cases of chronic aggressive hepatitis and
cirrhosis
and the latter is notable for its frequency in the first decade of life.
Hepatocellular carcinoma
also occurs rather commonly, although most often in the second decade and as a complication of
cirrhosis
. There is a marked male preponderance in chronic aggressive hepatitis,
cirrhosis
, hepatocellular carcinoma and schistosomiasis. It is unlikely that this is due to selection of cases and the series shows no indication of tribal influence. The possible role of infections and toxins, particularly in the genesis of chronic aggressive hepatitis and
cirrhosis
, is discussed. In the search for clues to pathogenesis, detailed systematic investigation of children with liver disease is advocated, paying particular attention to cultural background, and exposure to infections and toxic agents.

Hepatocellular carcinoma
is a major malignant disease in parts of Africa and Asia, including Korea. Surgical resection, which represents the best hope for cure, is limited by the extent of the disease and the high incidence of concurrent
liver cirrhosis
in Korea. We designed a phase II trial of combined external radiotherapy and hyperthermia for hepatocellular carcinoma that was unresectable due to either locally advanced lesions or associated
liver cirrhosis
so as to evaluate the efficacy and the safety of this combination regimen. This trial was performed at Yonsei Cancer Center between April 1988 and July 1988. External radiotherapy was delivered to a total dose of 3060 cGy/3.5 weeks. Hyperthermia was applied twice a week for a total of six treatment sessions using an 8-MHz radio-frequency capacitive-type heating device, i.e., Thermotron RF-8 and Cancermia. In all cases, hyperthermia was carried out within 30 min of the radiotherapy for a period of 30-60 min. The temperature in the tumor was measured by inserting a thermocouple into the tumor mass under ultrasonographic guidance in patients who did not have a bleeding tendency. The tumor response was assessed by CT scan after completion of the designed treatment. No complete response was obtained. However, a symptomatic improvement in abdominal pain was observed in 78.6% of cases and a partial response was achieved in 40% of the patients. The most important factor affecting the tumor response was the type of tumor (single massive, 71.4%; diffuse infiltrative, 20%; multinodular, 0; P < 0.005). The 1-year survival values determined for all patients and for the partial responders were 34% and 50%, respectively. The overall median duration of survival was 6.5 months. The median duration of survival for the partial responders was longer than that for the nonresponders (11 vs 5 months; P < 0.05). A mild degree of heat sensation, fever, first-degree burns of the skin, and nausea were observed as treatment-related adverse reactions. In conclusion, although this study is being continued, the results obtained thus for indicate that combined radiotherapy and hyperthermia seem to be effective in providing local tumor control and pain palliation in unresectable hepatocellular carcinoma while producing an acceptable level of toxicity.

Hepatocellular carcinoma
and obliterated hepatic bile duct were found at postmortem examination in a 4-year-old girl with arteriohepatic dysplasia (Alagille's syndrome). AFP level was extremely high.
Liver cirrhosis
was present on percutaneous needle biopsy 9 months before she succumbed in progressive liver failure. Episodes of repeated gastrointestinal, life-threatening hemorrhages occurred during the last 6 months of her life. Histopathologic findings of the eyes were documented at autopsy.

Hepatocellular carcinoma
is endemic in Africa, where in the incidence of the disease in males ranges from 20-100,000 per annum. The tumor tends to occur at a younger age compared to the age of presentation in Europeans or Chinese. The majority of African patients with HCC are HBsAg positive, but HBsAg is more commonly detected in younger vs older patients. Approximately 30% of patients are anti-HCV positive. Both these chronic virus infections may induce disease via the development of
cirrhosis
. Other environmental factors including carcinogens such as aflatoxin may act as co-factors. Resection rates for hepatocellular carcinoma are low in this population group, and screening for small tumours is not generally undertaken in Africa.

Immunohistochemical evaluation of Cu, Zn- and Mn-superoxide dismutase (SOD) activity in various viral liver diseases was performed by the peroxidase-conjugated antibody indirect method. Anti-human Cu, Zn-SOD (rabbit) and anti-human Mn-SOD (guinea-pig) derived and purified from SOD of human erythrocytes and placentas were used to determine SOD distribution in liver tissues. SOD in the liver tissues was detected in 68 inpatients of our unit. They consisted of 23 cases with chronic hepatitis caused by hepatitis B virus (13) and hepatitis C virus (10), 24 with
liver cirrhosis
caused by hepatitis B virus (5) and hepatitis C virus (19) (15: compensatory, 9: decompensatory) and 21 with hepatocellular carcinoma caused by hepatitis B virus (2) and hepatitis C virus (18) complicated of
liver cirrhosis
. In viral liver diseases, SODs in the liver tissues were distributed to hepatocytes mainly in the pattern of cytoplasmic diffusion. The incidence of immunohistochemical Cu, Zn-SOD and Mn-SOD were 47.8% and 56.5% in chronic hepatitis, 93.3% and 86.7% in compensated
liver cirrhosis
, 11.1% and 22.2% in decompensated
liver cirrhosis
, respectively. The aggression of viral liver disease was accompanied with the decrease of SOD concentration in the liver tissues.
Hepatocellular carcinoma
cells were negative for Mn-SOD in all cases, and weakly positive for Cu, Zn-SOD in 2 out of 21 cases. Comparatively strongly positive SOD findings were obtained from normal regions neighboring carcinomas. A close relationship between the depletion of SOD in liver tissues and carcinogenesis in viral liver diseases was observed.

Hepatocellular carcinoma
(
HCC
) is the most frequent malignant tumour of the liver.
HCC
has an incidence that changes with geographic areas (1.2-2.5% in western countries and 13-53% in Asia and Africa) as the risk of tumour bleeding. The patient arrives to the surgeon in emergency with no possibility of radical resection because of the patient's general conditions, the tumour's stage and the
cirrhosis
. Palliative treatments are: resection, direct suture of the bleeding tumour, artery embolization and selective binding of the hepatic artery. The Authors describe two cases of spontaneous rupture of
HCC
observed in the surgical department of Venice Hospital. A review of the literature is also reported.

Progressive degrees of metabolic alterations are frequent in
cirrhosis
impairing peripheral tissue and body composition.
Hepatocellular carcinoma
worsens protein wasting and malnutrition. A normal energy production rate and an abnormal substrate oxidation rate are well-known findings in
cirrhosis
; however, no data are available on cirrhotic patients with hepatocellular carcinoma. The aim of this study was to measure oxidative metabolism in cirrhotic patients with and without hepatocellular carcinoma and to investigate the correlation between energy production rate, respiratory quotient and nutritional state. Thirteen male cirrhotic patients with hepatocellular carcinoma (8 well-nourished and 5 malnourished) were compared with 17 cirrhotic patients without hepatocellular carcinoma (11 well-nourished and 6 malnourished) and six controls who were age and sex matched. A diagnosis of malnutrition was made if the fat mass percentage was reduced to less than 20% of the patient's body weight. Indirect calorimetry was performed between 8 and 10 AM, after a 12-hr fast, for 30 min (with a 10-min steady-state period), and measured energy production rate was calculated according to Weir's formula. Body composition was assessed by means of the Durnin and Womersley formula. Anthropometry and bioelectric impedance analysis showed no variations in kilograms of fat-free mass in our malnourished patients. Our data show that, when the energy production rate is measured while the patient is at rest and corrected for fat-free mass, the energy requirements of cirrhotic patients and cirrhotic patients with hepatocellular carcinoma matched that of the controls, regardless of nutritional state.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatocellular carcinoma
(
HCC
) is the most frequent malignant tumor of the liver and is associated with
cirrhosis
in 90% of cases. It is often a multicentric tumor with vascular involvement but surgical resection, when it is possible, remains the best treatment of
HCC
. Major resection is feasible in patients without liver insufficiency; patients with mild liver insufficiency can be treated by local resection. In selected cases, liver transplantation is indicated in order to prevent the high risk of recurrence of
HCC
which is observed after resection.
