Ascitic fluid samples from 19 patients with ovarian carcinoma, 3 with a benign ovarian tumor, and 5 with cirrhosis of the liver were examined for their content of coagulation factors and components of the fibrinolytic system. The concentration of trypsin inhibitors in the ascitic fluid was significantly higher in the presence of carcinoma. Large amounts of FDP were found in the ascitic fluid in all patients with malignant tumors, but not in the other two groups. Determination of FDP may therefore make it possible to differentiate between malignant and nonmalignant ascitic fluid.

The earliest and most reproduceable lesion associated with chronic alcohol abuse is fatty liver. In some alcoholics this may be superseded by alcoholic hepatitis, which may represent the link between the early lesion and cirrhosis. Alcoholic cirrhosis usually begins as a regular, monolobular variety, but is eventually transformed into an irregular, multilobular type. All stages of alcoholic liver injury have now been produced in the baboon, despite high protein and vitamin supplemented diets. Alcohol may therefore now be regarded as a direct hepatotoxin. Epidemiological studies have indicated that alcoholic liver injury begins with an intake of more than 80 g ethanol a day, and that cirrhosis is generally not seen with an intake of less than 160 g per day. The development of cirrhosis correlates with the total duration and amount of alcohol ingested. Complications of alcoholic cirrhosis include iron overload and primary hepatic carcinoma.

The presence of alpha-1-fetoprotein, the heat stable alkaline phosphatase and Australia antigen was examined in 103 patients with porphyria cutanea tarda, 300 patients with cirrhosis and 18 patients with primary liver carcinoma. The heat stable alkaline phosphatase was determined in 46 percent of patients with porphyria cutanea tarda and in 61 percent of patients with primary liver carcinoma. Alpha-1-fetoprotein was detected in 61 percent of patients with primary liver carcinoma and in 2 patients with porphyria cutanea tarda in whom primary liver carcinoma was proved later. The simultaneous occurrence of alpha-1-fetoprotein and the heat stable alkaline phosphatase was found in 50 percent of cases with primary liver carcinoma. Neither the patients with porphyria cutanea tarda nor the patients with cirrhosis were Australia-antigen positive. Australia-antigen could be detected only in one patient with alpha-1-fetoprotein positive-carcinoma of the liver.

Five cases of hepatocellular carcinoma in whom diagnosis was made when the tumor was relatively small, are described. In 2 cases, serum alpha-fetoprotein (AFP) strted to rise sharply, which enabled early detection and surgical removal of the tumor. Serum AFP was below 100 ng per ml, but above the upper normal limit by radioimmunoassay, and was unfluctuating for a considerable period of time before it began to rise in 2 cases. It was negative throughout in 1 case, who lived more than 4 years after the tumor had reached a detectable size. In 4 of 5 cases, the tumor seemed to have evolved during a stage of chronic hepatitis or its transition to cirrhosis. In 1 case with chronic schistosomiasis and advanced mixed macro- and micronodular cirrhosis, a 1.5-cm tumor was detected by celiac angiography. These observations on time relationship of oncogenesis may be generalized to modify the cirrhotic liver. Necessity is emphasized for the early detection of this type of carcinoma to monitor serum AFP in chronic hepatitis patients, particularly in those with unfluctuating, mildly abnormal levels of AFP.

The incidence of epi-cirrhotic liver carcinoma is apparently on the increase. Between 1969 and 1973 there were 84 cases of primary liver carcinoma and 467 of cirrhosis among 10211 autopsies. In 74 (16%) the carcinoma had developed in a cirrhotic liver. Clincally the diagnosis of carcinoma had been made in only 14 cases. The mean survival time after the diagnosis was seven weeks, after onset of the terminal symptoms 13 weeks. Typical clinical features were decompensated, hypertrophic, often coarsely granular, liver cirrhosis. The best diagnostic method was apparently laproscopy and determination of alpha 1-fetoprotein and cholestatic enzymes.

The frequency distribution of HBs Ag in different parts of the world reveals a relatively high frequency among healthy members of population groups inhabiting areas of high incidence of liver cell carcinoma. Similar high frequencies of HBs Ag are also found in those areas where macronodular cirrhosis is relatively common and is usually complicated by liver cell carcinoma. In geographic areas with low incidence of liver cell carcinoma and macronodular cirrhosis, a relatively low frequency of HBs Ag is usually encountered in the population. The frequency of HBs Ag is relatively higher in patients with liver cell carcinoma with or without cirrhosis than in comparable controls. The subtypes of the antigen do not correlate with the incidence of liver cell carcinoma and there is also no correlation between alpha fetoprotein and HBs Ag in the presence of liver cell carcinoma. HBs Ag is very rarely detected in patients with micronodular cirrhosis or in liver cell carcinoma which may be its complication. It would appear that HBs Ag is necrogenic in the liver and is capable of producing hepatic necroses or hepatitis which may progress to macronodular cirrhosis. The areas of hepatic necroses may either progress to liver cell carcinoma or the resultant macronodular cirrhosis may be complicated by carcinoma. The oncogenic potential of HBs Ag requires further studies.

"e" is a serum antigen associated with type-B hepatitis. It is found only in hepatitis B surface antigen (HBsAg) positive sera, but is antigenically distinct from HBsAg. e antigen was not detected in the serum of any of 99 cases of acute type-B hepatitis who recovered normally. Its antibody, anti-e, was found in 14 (14%). The antibody usually appeared before clearance of HBsAg and before appearance of HBsAb. Serum e was not detected in any of 29 symptom-free carriers of HBsAg, but 21 (73%) showed anti-e. Serum e was found in chronic active hepatitis (44%) and chronic persistent hepatitis (31%). The antibody, however, was detected in only 2 of 79 patients with chronic active hepatitis but in 7 (44%) of chronic persistent hepatitis. Serum e was not found in 5 patients with primary liver-cell carcinoma or 5 with inactive HBsAg-positive cirrhosis. The antibody was, however, found in all 5 of those with inactive cirrhosis and in 4 of the 5 with primary cancer. These results suggest that the presence of e antigen is associated with active and usually continuing liver disease. Anti-e, however, is associated with inactive liver disease and asymptomatic carriage of HBsAg, and its presence must be regarded as a valuable sign in predicting those who will escape progressive chronic liver disease.

(1) Passive hemagglutination and radioimmunoassay are suitable methods for the detection of AFP in the low concentration range. (2) In 3.72% of the cases a clinically unknown carcinoma was found in an unselected group of patients with liver cirrhosis. (3) 21.9% of the patients showed AFP elevations up to 2000 ng/ml. In 10.6% of this group, increasing titers demonstrated a primary liver cell carcinoma. In 89.4% a transitory rise of AFP was not associated with tumor growth. Levels return to normal values within three months in 90% of the cases. (4) Transitory AFP elevations are not correlated to clinical conditions (praecoma, coma, delirium, bleeding, ascites, shunt) or to biochemical parameters (GOT, GPT, bilirubin, prothrombin complex time, gamma-globulin). (5) A temporary rise in AFP is more frequently observed in groups with high hepatoma incidence than in groups with low hepatoma incidence. (6) Therefore, it may be suggested that a transitory rise of AFP could reflect a "primary reaction" of carcinogenesis. (7) Primary liver cell carcinoma is found to be more frequent in posthepatitic than in postalcoholic, cryptogenic, and other cirrhosis and to be more frequent in australia-antigen positive than in australia-antigen negative cases. (8) Routine serological tumor antigen screening of patients with a precancerous disease is useful.

The plasma level of alpha1-fetoprotein in 35 hepatic patients with a "cold" area showed by liver scanning has been detected by means of the radioimmunoassay technique. High levels (more than 320 ng/ml) of AFP were found in 4 cases of primary carcinoma of the liver; low concentration of AFP was found in 1 case of hepatoma. In 4 cases of liver metastasis the plasma levels of AFP were very low; the highest concentration (10 ng/ml) was found in a patient with a cancer of the colon. Low levels of AFP were found in all the cases (26) of hepatic cirrhosis, whereas high level of AFP was detected in 1 case of chronic hepatitis. The detection of alpha1-fetoprotein by the radioimmunoassay technique may be of value in the differential diagnosis between hepatoma and cirrhosis.

Primary carcinoma of the liver is rare in Western countries but it is a common malignant tumour in many parts of the tropics. Much has been learnt in recent years about its pathology, manifestations, and aetiology that is relevant to the whole field of oncology. The important distinction between carcinomas of liver-cell and bile-duct origin, the phenomenon of alpha-fetoprotein production, and the role of cirrhosis are discussed in the context of newly discovered aetiological factors such as gonadal steroids, mycotoxins, and the hepatitis B virus.
