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 case history of a 16-year-old boy with hepatocellular carcinoma and an intermediate deficiency of alpha1-antitrypsin (MZ phenotype) is presented. Previous reports have suggested that hepatocellular carcinoma may be associated with the Z variant of antitrypsin and either a severe or intermediate antitrypsin deficiency. The present case is unusual because of the rather high level of the serum trypsin inhibitory capacity for an MZ heterozygote (1.633 units), which may be due to involvement of the liver by the tumor or to a recent partial hepatectomy. PAS-positive antitrypsin globules were seen in the primary tumor and in nodules metastatic to the mesentery, as well as in nonneoplastic portions of the liver. Hepatocellular carcinoma is another disease state that may occur preferentially in individuals with either severe or intermediate deficiencies of alpha1-antitrypsin.

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 case of primary hepatocellular carcinoma metastatic to the gingiva is described. Hepatocellular carcinoma is an uncommon malignancy, generally occurring in a cirrhotic liver, which rarely metastasizes to the maxillofacial area. Of eight such cases in the English-language literature, the present case is the fourth involving metastasis to the gingiva. Hepatocellular carcinoma would seem to metastasize with equal frequency to the gingiva and to the mandibular bone. In the case described, histologic examination of the gingival lesion definitively established the diagnosis following somewhat equivocal results of needle biopsy of the liver.

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 epidemiology has undergone great changes in Japan. Life span, new diagnostic procedures and viral infections obtained through intravenous injections have contributed to these changes. The aetiological aspects and clinical features of HCC should be reappraised to account for the current use of techniques such as US and CT in the early diagnosis of HCC. In Japan most HCC seem to be HBV and/or HCV associated whereas small HCC seem to be HCV-associated more so than large HCC. The usual clinical symptoms and signs are somewhat useless and of limited value while the newer techniques permit an early clinical diagnosis of small HCC. This diagnostic advancement has also permitted a remarkable progression in HCC therapy.

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.

Hepatocellular carcinoma has rarely been reported in Wilson's disease, particularly in women. We describe the case of a female patient who was diagnosed with Wilson's disease at the age of 39 years, after presenting with severe neurological symptoms. She had significant neurological improvement following penicillamine therapy and succumbed to hepatocellular carcinoma at the age of 72 years, following 33 years of penicillamine therapy. The patient described here was the oldest and only the third female patient with hepatocellular carcinoma complicating Wilson's disease to be reported in the literature.
