Sixteen necropsies and 4 cases of hepatic resection in which the liver had a solitary hepatocellular carcinoma smaller than 4.5 cm, or a few tumor nodules smaller than 3.5 cm, have been analyzed. Clinically, these patients presented with signs and symptoms compatible with cirrhosis and, of the 16 autopsy cases only 2 had been diagnosed correctly. In all but 4 cases, the noncancerous parenchyma showed advanced cirrhosis of the mixed type, with irregularly sized multilobular nodules and thin strands of stroma, different from typical alcoholic cirrhosis. The primary lesion was grossly encapsulated in the majority, suggesting a slow, expanding growth. Histologically, most primaries were relatively well differentiated. Serum alpha-fetoprotein was generally low, and it served as the major diagnostic clue in only 5 cases. In patients with mildly abnormal alpha-fetoprotein levels, continuous monitoring seems important in order to detect a steady rise, the first warning for tumor growth.

Ther serum concentration of alpha-fetoprotein (AFP) was measured by radio-immunoassay in 98 patients with liver disease including hepatoma, chronic active hepatitis, alcoholic cirrhosis, and acute virus B hepatitis. Raised AFP levels, above 30 ng/ml, were found in 87% of patients with acute viral hepatitis, in 82% of patients with primary liver cell carcinoma, in 58% with chronic active hepatitis and in 14% of patients with alcoholic cirrhosis. However, levels above 1 000 ng/ml were found only in patients with hepatoma and in acute viral hepatitis.

During the 11 1/2 year period ending 13 months ago, 93 consecutive patients were treated with orthotopic liver transplantation. Fifty-six of the recipients were 18 years old or younger, and the other 37 were adults. The most common indications for operation were biliary atresia, primary hepatic malignant tumor, chronic aggressive hepatitis and alcoholic cirrhosis. There has been a gradual improvement in results throughout the period of study, although to a satisfactory level. Twenty-seven of the 93 patients survived for at least one year after liver replacement with a maximum of six years, and 16 are still alive after 13 to 71 months. The 11 late deaths after one to six years were caused by chronic rejection, biliary obstruction, recurrence of hepatoma, systemic infection or hepatitis of the homograft. Rejection of the liver as judged by classical histopathologic criteria played a surprisingly small role in the heavy over-all mortality, accounting for less than 10 per cent of the deaths. Technical or mechanical problems, especially those of biliary duct reconstruction, were a far greater cause of failure, as were systemic infections. Six of the 37 adult recipients had lethal cerebrovascular accidents during, or just after, operation. When abnormalities of liver function developed in the postoperative period, the nearly automatic diagnosis of homograft rejection, in retrospect, proved to have been wrong in most instances. Further development of liver transplantation depends upon two kinds of progress. There must be reduction of operative and early postoperative accidents and complications by more discriminating patient selection, purely technical improvement and better standardization of biliary duct reconstruction. The second area will be in sharpening the criteria for the differnetial diagnosis of postoperative hepatic malfunction, including the liberal use of transhepatic cholangiography and needle biopsy. Only then can better decisions be made about changes in medication or about the need for secondary corrective surgical procedures.

A 61-year old white male, known to have alcoholic cirrhosis, presented with massive fresh bleeding per rectum. Various investigations failed to ascertain the cause of bleeding. Hepatoma of the liver was revealed by selective hepatic and superior mesenteric angiography. Massive lower gastrointestinal bleeding occurred again one month later and was rapidly followed by death from hepatic coma. An extensive hepatoma infiltrating the adjacent hepatic flexure of the colon was found at autopsy, the colonic infiltration explaining the lower gastrointestinal hemorrhage.

The chief causes of liver disease in Ethiopia are reviewed, considering hospital data on admissions for hepatitis, cirrhosis, ascites and hepatoma. Liver diseases account for 11.4% of all medical admissions in 3 medical wards in Addis Ababa. The causes are viral hepatitis, post- hepatic and post necrotic and mixed cirrhosis and hepatocellular carcinoma. Alcoholic cirrhosis is rare. Viral hepatitis with shivering, rigor and fever and elevated direct bilirubin levels are common in Ethiopians, especially in child-bearing women. The hepatitis B surface antigen (HBsAg) is often associated with hepatitis. The disease may be transmitted by several species of mosquitoes, placental transmission, or feces, urine, saliva or semen. Blood products are not screened for hepatitis B. Cirrhosis is common, and causes significant mortality, usually from esophageal varices and hepatic coma. Chronic active hepatitis patients may live for a time, especially if they are near a hospital and are treated with steroids. In Ethiopia presenting symptoms for hepatoma are anorexia, weight loss, persistent, burning, right upper quadrant pain, and a hard, nodular, tender RUQ mass. Over 5% of malignancies seen are primary hepatocellular carcinomas. 50% have HBsAG, compared to 3.8% of controls. 65% have alpha-fetoglobulins. It is suggested that some viral hepatitis cases progress to cirrhosis, of which some go on to hepatocellular carcinoma. Herbal medicines, aflatoxins and other toxins may also contribute to liver disease.

Consecutive liver biopsies in a large general hospital for Blacks over the period 1959 - 1960 were compared with those in the 2-year period 1975 - 1976. Changes were noted in the histological appearances of micronodular cirrhosis. With the liberalization of the liquor laws and the granting of access to hard liquor to Blacks, fatty change, alcoholic hepatitis, alcoholic hyalin and alcoholic cirrhosis are making their appearance in the micronodular cirrhosis of the South African Blacks, features which were never observed when alcohol consumption was confined to homebrewed beverages containing large quantities of iron derived from the metallic containers in which liquor is brewed. No change in the histological picture or incidence of macronodular cirrhosis and hepatocellular carcinoma was observed.

The serologic and tissue markers of hepatitis B virus (HBV) were studied in 50 patients in whom hepatocellular carcinoma (HCC) was confirmed at autopsy. Serologic and tissue markers included serum hepatitis B surface antigen (HBsAg), tissue HBsAg, tissue hepatitis core antigen (HBcAg), and serum antibody to HBcAg (anti-HBc). Twenty-two patients had HCC arising in alcoholic cirrhosis; 2 of the 22 (9.1%) had one or more of the HBV tissue and serologic markers. This infection rate is similar to the rate of 7.9% observed in 63 control alcoholic cirrhotic patients without HCC. In contrast, 15 of 20 (75.0%) patients with HCC in nonalcoholic chronic active liver disease showed evidence of active HBV infection. One of 8 patients with HCC in normal liver had serum HBV markers. This result indicates that there is an extremely high prevalence of HBV infection among HCC patients with nonalcoholic chronic liver disease in the U.S.A. The prevalence of HBV infection in these patients is as high as that observed in Asia and Africa. Thus, it can be concluded that the lower prevalence rate of active HBV infection in HCC patients in the U.S.A. is the result of statistical dilution of HCC-B-viral disease by the large numbers of the alcoholic cirrhotic patients with HCC, and that if chronic active hepatitis type B were as common in the United States as it is in Africa and Asia, the frequency of occurrence of HCC might also be as high.

Sera of 173 patients with various forms of liver disease along with serum precipitates produced by polyethylene glycol were screened for the presence of a microsomal antigen referred to as ubiquitous tissue antigen (UTA) and its antibody by double diffusion precipitation in agarose gel. UTA was detected in 7 or 26 patients with chronic active hepatitis, 1 of 5 with alcoholic hepatitis, 2 of 14 with alcoholic cirrhosis and 18 of 98 with hepatoma. Antibodies to UTA were found only in 2 patients with chronic active hepatitis, 1 with alcoholic cirrhosis and 1 with hepatoma. No UTA or its antibody were noted in sera of 5 patients with alcoholic fatty liver, 10 patients with hepatitis B, and 15 asymptomatic carriers of HBsAg. Positivity for the UTA or its antibody was restricted to severe, chronic cases irrespective of diagnosis, indicating that persistent tissue destruction might be necessary for antigen release or antibody formation.

This is a study of aetiological associations in patients with primary hepatocellular carcinoma (PHC). Thirty new patients with PHC were seen in a five-year period. The most common aetiological association was alcoholic cirrhosis. This was implicated in the development of PHC in 13 patients. However, since the introduction of radioimmunoassay for hepatitis B surface antigen (HBsAg) there have been six patients with HBsAg-associated PHC. Thus, for the first time, an association of hepatitis B virus with PHC is described in this country.

Thirty patients with alcoholic cirrhosis, ascitic during 13.6 +/- 13 months (mean +/- S.D.) were cured of ascites and followed up during 2 to 9 years (4.3 +/- 2.7 years). Twenty six were compared with a same number of cirrhotics, matched for age and sex, who died during the year after the first admission. Many biological data show statistical difference. Nevertheless no valuable prognosis can be predicted in an individual case. The clinical improvement is associated with major, sometimes total biological recovery. Other complications of cirrhosis (gastro-intestinal bleeding, hepatoma) may occur (7 cases with 5 deaths) or alcoholic hepatitis if alcohol withdrawal is stopped (3 cases, 2 deaths). Some associated diseases look unexpectedly frequent: diabetes (4 cases), obesity (9), nodular lipomatosis (14 cases) whose frequency looks higher than that can be calculated for a similar group of healthy subjects.
