Certain characteristics of 328 Mozambican male Shangaans with primary hepatocellular cancer (PHC) have been compared with those of 163 Shangaan men with hepatomegaly from causes other than PHC and with those of 122 Black Southern African men with the same tumour but who belonged to tribes other than the Shangaan. Shangaans with PHC were significantly younger than non-Shangaans with the tumour (mean age 33,4 cf. 40,0 years; Pless than 0,001). They also had a significantly higher positivity rate of alpha-fetoprotein by immunodiffusion (71,4%) than the non-Shangaans (16%), although in other respects the tumours appeared to be similar. Cirrhosis of the non-tumorous part of the liver was present at necropsy in 62% of the Shangaans and in 66% of the non-Shangaans. The hepatitis B (surface) antigen (HBsAg) was detected in the serum of 60% of the Shangaans with PHC compared with only 9% of the controls. The antigen was present in 53,4% of the non-Shangaans with PHC (the difference between this fifure and that in the Shangaans was not significant). HBsAg was detected in the serum of 64% of the Shangaans with PHC and cirrhosis, but also in 74% of those with the tumour without associated cirrhosis. The possible role of the hepatitis B verus in the aetiology of PHC is considered in the light both of these findings and of the possibility that the frequency with which the tumour is associated with cirrhosis may be decreasing in Shangaans. Some of the dietary habits of the Shangaans with PHC were compared with those of the controls. Virtually all the patients with PHC, but also almost all the controls, ate groundnuts in large quantities from an early age, as well as cashew nuts in smaller amounts. Cycad pips, mopani leaves and pods, mopani worms and locusts were not eaten by significantly more of the Shangaans with PHC than the controls. The limitations of this type of dietary analysis are discussed.

The present study reports findings on the disposition of epirubicin after an intrahepato-arterial administration of the Lipiodol-drug complex, prepared by mixing the drug-aqueous phase with the iodized oil by ultra-sonification, in 14 patients with histologically proven hepatoma or hepatomegaly with serum alpha-fetoprotein level above 500 micrograms.l-1. The volume of Lipiodol used was 5 ml and the epirubicin dose was 50 mg.m-2. Blood samples were obtained at various time intervals up to 72 h post-dose. Serum concentrations of epirubicin were measured by liquid chromatography with fluorometric detection. The area under serum concentration-time curve (AUCinfinity0) was higher in the Lipiodol-epirubicin group (n = 8) while the clearance was faster and elimination t1/2 and mean residence time shorter in the plain epirubicin group (n = 3). However, interindividual variation in metabolism of epirubicin would affect serum level of the drug. In three patients who were given intravenous and intrahepato-arterial injections (90 mg.m-2) of plain epirubicin and Lipiodol-drug complex, the relative bioavailability of Lipiodol-epirubicin complex (F = 0.76 and 0.45) was lower than that of plain epirubicin (F = 0.80 and 0.73) in two patients while it was approximately 100% (F = 1.06 and 1.20) in one patient. It is likely that liver function of the patients might be modified by the disease state over a period of 3 months in the cross-over study. Further studies with larger patient samples are required to confirm if there is a targeting effect of the Lipiodol-drug complex toward hepatoma using a better formulation of the drug in Lipiodol.

The records of one hundred and four patients with confirmed hepatocellular carcinoma seen over a two year period at the National University Hospital were analysed to elucidate the clinical features of our local patients and to assess their response to various therapeutic modalities. Chinese males were over-represented with a peak frequency in the sixth to eighth decade of life. Seventy-five percent of the patients were HBsAg positive and at least 88% had evidence of previous Hepatitis B infection. Ninety-one percent were symptomatic at presentation with pain being the most common symptom. Hepatomegaly with features of cirrhosis were the main physical findings. Seventy percent of the patients presented within three months after the onset of symptoms. The majority of patients had stage II or III disease at diagnosis. Twenty percent of patients had normal alpha-fetoprotein levels. Chemotherapy did not appear to show a survival benefit. Curative surgical resection was feasible in about 10% of patients and it remains the only chance for long term survival. There is an urgent need to identify more effective drugs or other modalities to treat this common and rapidly fatal malignancy. Identification of high risk patients should prompt screening with both serum alpha-fetoprotein and ultrasonography of the liver.

A case of infantile hemangioendothelioma of the liver presenting with congestive heart failure and massive hepatomegaly in a two-mth old baby is described. Serum alpha-fetoprotein was elevated in this patient and clinically the lesion might not be distinguishable from other, commoner hepatic tumours in children. Histologically the tumour showed a type II pattern as defined by Dehner. The significance of classifying this tumour into two histologic types is discussed. Only 3 cases reported in the English literature were studied by electron microscopy; two of them were type I while the other was a type II lesion. In our case the endothelial cells appeared ultrastructurally less differentiated and architecturally more disorganized than in type I lesions. Like the previous case, the basal lamina showed marked thickening and reduplication. The significance of these findings is discussed.

A 19-year-old female had ascites, an enlarged liver, pelvic masses, and an alpha-fetoprotein level of 397,000 micrograms/L with a normal beta-human chorionic gonadotropin serum level. Abdominal exploration revealed a large solitary liver mass with bilateral ovarian masses, and bilateral salpingo-oophorectomy and wedge liver biopsy were performed. The tumor was composed of cords, nests, and pseudorosettes of polyhedral cells with eosinophilic cytoplasm and nuclei with prominent nucleoli. The clinical, light microscopic, and immunocytochemical features indicate that the primary liver neoplasm and ovarian metastases were a purely epithelial hepatoblastoma. To the authors' knowledge, this is the first reported case of this type.

Ten adult white patients (21-75 years old; six women, four men) presented with large cell lymphoma of the liver. Each complained of abdominal pain and/or an abdominal mass, and five had B-symptomatology of weight loss, fever (one patient), and night sweats (three patients). At laparotomy (eight patients) or by computerized tomography, liver-spleen scan and lymphangiogram (two patients with percutaneous liver biopsy only), the liver was the sole site of involvement, although subsequent staging procedures revealed bone marrow involvement in three patients. Initial biopsy interpretation was incorrect in four cases which were diagnosed as poorly differentiated carcinoma. Although uncommon, the differential diagnosis of primary liver lymphoma should be entertained when patients present with solitary (three cases) or multiple (six cases) liver defects, particularly when alpha-fetoprotein and carcinoembryonic antigen levels are normal. One patient had diffuse hepatomegaly. Treatment included biopsy (eight patients) or resection (two patients) followed by combination chemotherapy. All patients are alive from 0 to over 10 years (mean, 2.4; median, 1.8 years): six in complete remission, two with less than 6-months follow-up, and two with recurrent lymphoma. Examination of this group of patients along with 19 cases identified in the literature suggests that this is a more treatable disease than primary liver carcinoma.

A 57-year-old man with hepatocellular carcinoma with left thigh-bone metastasis is reported. He was admitted to the hospital with left leg pain. A diagnosis of bone metastasis of unknown origin was based on X-ray films. Physical examination revealed hepatomegaly. Liver function tests showed a slight increase of alkaline phosphatase, GOT and GPT. In serological tests, the levels of alpha-fetoprotein and carcinoembryonic antigen were high. HBs antigen was negative. From the above data, hepatocellular carcinoma was diagnosed.

Clinical observations of patients with primary hepatocellular carcinoma (PHC) at Le Dantec Hospital, Dakar, Senegal, were studied to determine a correlation with hepatitis B virus (HBV) infection. Of the 103 patients with PHC, 80 had an active HBV infection (HBsAg and/or anti-HBc); 23 showed signs of previous HBV infection (anti-HBs and anti-HBc). The two groups were similar in the detection of alpha-fetoprotein (approximately 60%) and in the major clinical findings: hepatomegaly, 76.25% and 86.96%, respectively; and ascites, 57.50% and 47.83%, respectively. Jaundice, however, was three times more frequent (P < 0.01) in the group of patients with signs of active HBV replication. Distribution of HBV markers as a function of age at onset of PHC revealed that the presence of HBsAg was primarily confined to the sera of the younger patients (< 50 yr old). When compared with leprosy patients and blood donors, the younger PHC patients differed in the frequency of detection of HBsAg and anti-HBs. The older people (> 50 yr old) in the three groups (PHC patients, leprosy patients, and blood donors) had identical HBV markers.

The patient was a 60-year-old Japanese male. He complained of epigastralgia and right chest pain of 4 month's duration, and general malaise, nausea and vomiting of 2 month's duration. Physical examination revealed on the right third rib a tender mass with a diameter of 2 cm and hepatomegaly with a multi-nodular surface and red palms. There were no signs of carcinoid syndrome, such as cutaneous flushing. Laboratory examinations disclosed certain biochemical alterations; alkaline phosphatase 810 IU/l, gamma-glutamyl transpeptidase (gamma-GTP) 2090 IU/l, carcinoembryonic antigen (CEA) 23.5 ng/ml and alpha-fetoprotein (AFP) 6,800 ng/ml. Both HBs-Ag and HBs-Ab were negative. The patient died in a uremic state, with rapid increases of jaundice and ascites. Autopsy revealed gastric carcinoid with extensive metastases to the liver and the bone marrow. Tumor cells showed argyrophilia but not argentaffinity. Immunofluorescence specific for AFP was positive in the hepatocytes, particularly those adjacent to the metastatic tumor cells but not in the tumor cells, either primary or secondary. 79 cases reported in Japan of serum AFP-positive malignant tumor other than hepatocellular carcinoma and certain other malignancies of germ cell origin are reviewed and discussed.

Hepatoblastoma was diagnosed in a 12 month old boy presenting with hepatomegaly and isosexual precocious puberty. Preoperative levels of both alpha-1-fetoprotein (AFP) and human chorionic gonadotropin (HCG) were highly elevated. The tumor was removed by hepatic trisegmentectomy. Tumor tissue contained high concentrations of AFP and HCG. On combination chemotherapy with cyclophosphamide (CYC), vincristine (VCR), adriamycin (ADR) and 5-fluorouracil (5-FU) HCG dropped over a period of 9 months to normal values. In contrast, AFP was undetectable following surgery. One year after initiation of therapy there is no clinical or radiological evidence of recurrence of the malignancy but the observation period is too short to draw any conclusions on the effect of therapy and the final outcome.
