All the cases of proven hepatocellular carcinoma seen at Westmead Hospital, Sydney between January 1980 and the end of 1987 were reviewed. Hepatitis B infection was the major predisposing condition. Six patients had taken significant doses of sex steroids. Seventeen of the patients were cirrhotic at the time of diagnosis and in seven of these there was a significant history of
alcohol abuse
. AFP was elevated in only 15 of the 34 patients. Multiple regression analysis revealed that the single, independent determinant of a raised AFP level was found to be presence of Hepatitis B infection. Resection was possible in 10 patients. In the last ten months, seven patients have been treated by embolisation of the tumour with Adriamycin bonded to lipidol. Survival was influenced by the presence or absence of
cirrhosis
but not by evidence of Hepatitis B infection. The prognosis for patients with hepatocellular carcinoma in Australia is as dismal as it is in any other country. Although a rare tumour its incidence may well increase as the community now contains relatively greater numbers of immigrants from areas where the risk of developing a hepatocellular carcinoma is higher and because of the number of drug addicts who are frequently exposed to Hepatitis B infection. With the exception of patients with Hepatitis B infection, screening with AFP holds little promise in the Caucasian community.

Alcohol abuse
is widespread and alcoholic liver disease represents a major medical and social problem. The spectrum of alcoholic liver injury is currently grouped into three clinical forms: fatty liver, alcoholic hepatitis and
cirrhosis
. The rational management of alcoholic liver disease can be divided in non-specific therapy and in specific treatment. The most important aspect of non-specific therapy is cessation of alcohol consumption: the abstinence diminishes symptoms and improves signs, and significantly increases survival. As to specific treatment, a number of controlled clinical trials of various forms of therapy have been carried out. Steatosis is spontaneously reversible after cessation of alcohol consumption, and therefore no treatment is necessary. For hepatitis, a number of protocols have been studied with both low and high doses of corticosteroids, cyanidanol, penicillamine, synthetic thyroid antagonists, hormones, and amino acids. Results have been negative, disappointing, or contradictory. In
cirrhosis
, corticosteroids and colchicine have been used: the former were ineffective while clinical and histological improvement as well as reduced mortality were obtained with the latter. Especially interesting results were registered after treatment with polyunsaturated phosphatidylcholine which has been used for steatosis, acute hepatitis and
cirrhosis
with good clinical, histological, and biohumoral findings.

Metastatic patterns of hepatocellular carcinoma (HCC) in 6997 autopsy cases recorded in the Annual of the Pathological Autopsy Cases in Japan from 1981 to 1984 were analyzed by using a computer. Significant association of the metastatic pattern of hepatocellular carcinoma with age and sex was shown after separating patients into different age groups in pack years. It was especially worthy of notice that bone metastasis decreased in an age-dependent manner only in men within the widest age range (P less than 0.001) and was significantly prevalent in men in their forties and fifties (P = 0.012). In addition, in 350 cases of hepatocellular carcinoma autopsied at Tokyo University Hospital during 15 years from 1971 to 1985, it was suggested that bone metastasis might be prevalent in male patients with
liver cirrhosis
although significant relationship between bone metastasis and hepatitis B virus infection or
alcohol abuse
was not shown. These results might indicate possible effects of sex differences on the metastatic pattern of hepatocellular carcinoma, particularly bone metastasis, as well as on the incidence of the cancer.

Chronic alcoholics with
cirrhosis
often develop symptoms of zinc deficiency. Tetraethylthiuram disulfide (TTD) is metabolized to two molecules of diethyldithiocarbamate (DDC). DDC chelates divalent metal ions, including zinc, by forming highly lipophilic neutral bis(dithiocarbamate)-metal complexes. DDC could therefore enhance the intestinal zinc uptake or increase the rate of zinc excretion. Accordingly, treatment of alcoholism with TTD could either aggravate or alleviate zinc deficiency. The present study investigated effects of DDC and TTD on intestinal zinc uptake and on the rate of zinc excretion in mice. When given as very high single oral doses, DDC and TTD increased the intestinal uptake of a single oral dose of zinc. When added to the diet and administered in lower doses, closer to those administered to humans for treatment of
alcohol abuse
, both compounds were without effect on the rate of excretion of the body's zinc stores. In a long-term experiment, where 65Zn was administered in the drinking water, these doses of TTD and DDC reduced the whole-body retention of 65Zn. No treatment changed the organ distribution of zinc in any of the experiments. In conclusion strong indications emerge from the present study that TTD treatment of alcoholism is more likely to reduce the intestinal zinc absorption than to enhance it as has been suggested by other authors. Thus, the widely used experimental model using single oral exposure to metal and chelator conceivably may give erroneous results, when used to predict effects of prolonged exposures.

The findings at 26.879 autopsies, that is 70% of all the deaths registered in the Province of Trieste, obtained at the Institute of Pathologic Anatomy and Histology of Trieste from 1976 to 1985 were studied. Liver cancer showed in the Province the World Standardized Incidence Rate (WR) of 1.87 (females) and 12.78 (males), one of the highest ever observed in nonendemic areas. In view of close association between cancer of the liver and
cirrhosis
(88%), the authors studied the most important etiological factors of
cirrhosis
in the region, i.e. hepatitis B and
alcohol abuse
. Some effective measures are suggested to decrease the incidence of
cirrhosis
and eventually cancer of the liver.

The possibility to detect the antibody to hepatitis C virus (HCV) has allowed to estimate the prevalence of this virus in patients with hepatic disease, mostly in those with hepatitis considered non-A non-B. Literature shows that HCV causes about 75% of cases of cryptogenic hepatitis and more than the 90% of post-transfusional hepatitis. Circumstantial evidence suggests the existence of a relationship between parenterally-transmitted non-A non-B hepatitis (PTH) and primary liver cancer (PLC). With the advent of anti-HCV, it is now possible to assess directly whether or not there is a relationship between PTH and PLC. So anti-HCV was looked for in the sera of 365 patients with
cirrhosis
prospectively followed-up for early detection the development of PLC, using an enzymatic immunoassay (ELISA Ortho DS). At baseline anti-HCV was detected in 221 patients (60%). During 5-39 month 53 patients developed PLC and anti-HCV was detected in 68% of them. The univariate analysis demonstrated that
alcohol abuse
, anti-HBs and anti-HBc were the only covariates that were significantly associated with an increase risk of developing PLC. When these factors were introduced in the step wise regression analysis, age and alcohol were found to be the only independent risk factors. The high prevalence of anti-HCV found in patients with
cirrhosis
and PLC suggests that HCV might play a role in this tumor; the frequent co-occurrence of HCV and HBV markers suggests that HCV-HBV coinfection might be pathogenically important; alcohol was the most important non-viral risk factor for PLC.

One hundred consecutive cases of hepatocellular carcinoma (HCC) in
cirrhosis
observed at autopsy were studied and their pathological aspects were compared with those reported in the literature. The results, which are representative of HCC epidemiology in a geographical area where
cirrhosis
is mostly due to
alcohol abuse
, show that similarities in the architectural pattern of HCC and weight of the liver exist between our material and samples with different aetiology and epidemiology. A relationship between the histological grade of HCC and its propensity to metastasize was demonstrated. The reported better prognosis of clear cells per se could not be confirmed, although clear cell HCC occurred exclusively in grade 2. It was also demonstrated that the relationship between grading and staging was strongly influenced by the association of HCC with
cirrhosis
, which is a fact that is usually overlooked by the common staging (and grading) methods.

An investigation was conducted to clarify the relationships of IgA to the human liver. Immunocytochemical studies were performed on biopsy specimens from patients with
cirrhosis
and chronic hepatitis without any apparent history of
alcohol abuse
. The results showed that 1) a large amount of IgA is associated with the sinusoidal surface of hepatocytes, endothelial cells and Kupffer cells, 2) this IgA contains J chain and can form a complex with secretory component, and 3) this mainly belongs to the IgA1 subclass, 4) IgA in vesicles within hepatocytes and Kupffer cells is always associated with acid phosphatase activity, and 5) IgA containing vesicles within ductular epithelial cells always lack such enzyme activity. We conclude that 1) the IgA bound to the surface of hepatocytes, sinus endothelial cells and Kupffer cells is polymeric IgA1 uncomplexed with SC, and 2) this IgA occasionally enters these cells, and may be degraded in the lysosomes. 3) Polymeric IgA combines with SC in the ductular epithelium and may be secreted into bile. These findings suggest that J chain-linked polymeric IgA bound to the surface of hepatocytes and Kupffer cells has a certain pathological significance in liver diseases and might be involved in the clearance of excess IgA from the circulation.

The studies addressing the risk of development of
cirrhosis of the liver
in relation to alcohol consumption have been based on comparisons at the aggregate population level and at the individual level, on case-control studies and cohort studies, and on retrospective and prospective assessment of alcohol consumption. The ideal, but unfeasible, study design for estimation of the risk function is a prospective monitoring of alcohol consumption and recording of rate of development of
cirrhosis
per unit of time. Two recent studies, approaching this design, suggested that above a rather low, but not precisely determined, level of alcohol consumption, the risk of development of
cirrhosis
is not further influenced by the amount of alcohol consumed. A critical analysis of previous studies suggests that this risk function actually is compatible with their findings. The contention that
alcohol abuse
has a permissive rather than a dose-dependent role in the development of alcoholic liver injury encourages research into the additional factors that must act before the liver injury occurs.
