The prevalence of hepatitis B viral infection has been evaluated by means of a questionnaire. Contributions were made by 160 institutions from 39 countries and involved more than 400 collaborators. HBsAg was identified by a variety of test kits which were available at the time of the questionnaire. Data are presented for the prevalence of HBsAg in acute viral hepatitis, chronic hepatitis,
cirrhosis of the liver
and primary
liver cancer
. Wide variations in antigenaemia were identified in different countries and between the various forms of liver disease. HBsAg is positive more often in chronic hepatitis than
cirrhosis
. More data using sensitive tests are needed but it appears as if at least one-fifth of the world population has had a previous hepatitis B virus infection.

A retrospective survey organized by the Spanish Association for Digestive Endoscopy among its members has revealed that a correct diagnosis of primary
liver cancer
could be made by guided biopsy during laparoscopy in 153 of 208 cases. A diagnosis of malignancy was made in 103 of 145 cases of carcinoma associated with
cirrhosis
and in 50 of 63 cases without
cirrhosis
, but in the latter, the lesions were endoscopically indistinguishable from metastatic nodules in most instances. Biopsy was positive in 88% of all suspicious cases. Carcinomatous invasion of seemingly benign cirrhotic nodules could be demonstrated in 22 other patients.

The activity of GOT, GPT, APh, liver APh, gamma GTP, AAP and serum cholinesterase were determined in 80 patients with chronic liver diseases, diagnosed clinically, laparoscopically and by liver biopsy. Out of the patients with
liver cirrhosis
(51), those with portal cirrhosis (40) have a considerably higher activity of gamma GTP, intestinal APh than the patients with postecrotic
cirrhosis
(11). Cholinesterase activity is markedly lower in patients with
cirrhosis
and ascites than in the patients without ascites. With the histological data about the activity gamma GTP and GOT are considerably higher without activity. Examinations were carried out also upon patients with chronic aggressive hepatitis (4), chronic persisting hepatitis (9),
liver cancer
(12) and liver steatosis (4). The data revealed that the majority of the enzymes are with a higher sensitivity (especially gamma GTP, GOT, liver APh, cholinesterase) but with more restricted diagnostic and differential-diagnostic potentialities in view of the great dispersion of the enzyme activities with the separate liver diseases.

The age-standardized incidence rate of primary
liver cancer
(PLC) in Geneva was 9.7 per 100,000 in males, a figure four or five times higher than incidence rates reported elsewhere in Europe . These PLC's were often associated with
cirrhosis
and alcoholism. This indicated that the toll of PLC related to alcoholism and to alcoholic cirrhosis may be greater than anticipated.

The etiologic relationship of parasitic liver disease to primary
liver cancer
has long been debated. For this reason, a review of 4611 necropsies was carried out to determine the frequency with which hepatocellular carcinoma occurred in association with schistosomiasis. Of 227 cases of hepatocellular carcinoma, 24 (10.6%) were associated with schistosomiasis japonica. This was significantly higher than the incidence of this carcinoma without schistosomiasis (2.78%). The majority of the 24 cases exhibited the features of a mixed macronodular and micronodular
cirrhosis
(Gall's posthepatitic
cirrhosis
); this was super-imposed upon and caused a masking of schistosomiasis fibrosis. By radioimmunoassay hepatitis B antigen was positive in 27% of these cases. A review of the literature indicated that chronic schistosomiasis, on its own, is unlikely to be the cause of primary liver cell carcinoma. Histologic features resembling post-hepatitic
cirrhosis
combined with a high frequency of hepatitis B antigen suggest that viral hepatitis rather than S. japonicum is the more likely etiologic factor involved, or has a synergistic effect on carcinogenesis.

Necropsies were performed on 285 consecutively unclaimed Orang Asli bodies from Gombak Orang Asli Hospital during an eight-year period from May 1967 to April 1975. Of the 25 malignant neoplasms, hepatocellular carcinoma was by far the commonest (36%). The nine patients with this neoplasm had coexistant macronodular
cirrhosis
. There were 20 cases of
cirrhosis
; 45% of these had coexistant hepatocellular carcinoma. The 53,000 Orang Aslis living in West Malaysia comprise three tribes, the Negrito, Senoi, and Melayu Asli (Proto Malays). The Sinoi appear to have a high predilection for
liver cancer
, all our nine cases occurring in this group. These aboriginal people live in the jungles where they practice shifting cultivation and maintain their own dietary and social customs. Detailed studies of their dietary habits may provide a clue to the etiology of
liver cancer
in these people.

Necropsy and clinical data show that primary hepatocellular carcinoma (PHC) is the commonest cancer among the Senoi (a Malaysian aboringine group). The other aboringine tribes do not appear to have this high predilection for
liver cancer
. In the necropsy series, PHS was present in 10 out of 22 Senoi patients with
cirrhosis
. All the 22 livers contained hepatocytes that stained with Shikata's orcein stain and specific immunoperoxidase and immunofluorescent stains for hepatitis B antigen (HBAg). This observation raises the strong possibility that hepatitis B may be an important etiologic factor in the development of
cirrhosis
and PHC in the Senoi. The reason for the high susceptibility of the Senoi for HB virus infection is not clear, and the role of aflatoxin in the pathogenesis of PHC in the Senoi has yet to be determined. That the Senoi are a numerically small community, maintaining their own unique dietary and social customs and living in readily accessible areas in the Malaysian jungle, makes them an ideal population for the study of factors in the etiology of
liver cancer
.

The effects of treatments with diethylnitrosamine (DENA) and hepatitis B virus (HBV) on macaque monkeys were investigated by virus serology and by light and electron microscopy. The experimental groups comprised 43 newborn or juvenile cynomolgus and rhesus monkeys of both sexes. HBV neither had a carcinogenic effect nor increased the oncogenic effect of DENA. However, HBV given to juvenile primates before treatment with DENA resulted in subsequent gross and microscopic alterations consistent with mild hepatitis and postnecrotic
cirrhosis
; multifocal liver carcinoma apparently developed within these cirrhotic nodules. The pathologic findings in the experimental animals were strikingly similar to those observed in
liver cancer
patients.

In 9 years in Kenya, 34 examples of primary
liver cancer
wer diagnosed in patients in the first two decades of life. This represents 4.7% of all liver cancers during this period. The larger proportion (29) were hepatocellular carcinoma. In the second decade, there was a notable association with macronodular
cirrhosis
. Analogy with experimental work suggests that cells in mitotic cycle may be more vulnerable to the effect of environmental carcinogens. Five examples of hepatoblastoma were identified at ages from 2 months to 14 years; none showed the features of "mixed" tumours. The ratio of hepatoblastoma to hepatocellular carcinoma was the reverse of that found in other large series of juvenile hepatic tumours. The histopathological features of these tumours are described and problems of their classification are discussed.

A 65 years old, female patient with acquired aplastic anemia secondary to frequent exposure to hair dye. While on treatment with anabolic steroids hormone became jaundiced and developed hepatomegaly eight months later. During laparotomy the liver was enlarged, hard, with multiple whitish nodules on its surgace but was otherwise normal. Liver biopsy showed hepatocellular carcinoma, there were not
cirrhosis
niether hemochromatosis. A review of the related literature was done and discussed on the experimental and clinical evidences that suggested that androgens may play same role on the etiology of
liver cancer
.
