Comparison of anamnestic history, alcohol intake and smoking, nutritional status, and liver dysfunction between thorotrast patients who developed primary liver cancer and those who did not.

In order to clarify the differences in past history, nutritional condition and, consumption of alcohol and tobacco, and liver dysfunction between the thorotrast patients who developed primary liver cancer and those who did not, 103 persons who had no primary liver cancer in January 1980 were studied. All subjects were military men who had undergone angiography with thorotrast between 1943 and 1946. Twenty persons developed hepatocellular carcinoma and 16 developed intrahepatic bile duct carcinoma by April 1987, whereas 67 are still alive without any cancer. There was no difference in age or period after thorotrast infusion between those two groups of patients in January 1980. A difference in history of hepatitis and/or jaundice and presence of hepatic dysfunction was found between the subjects who developed primary liver cancers and those who did not. These findings suggest that an anamnestic history of hepatitis and liver dysfunction are risks for development of thorotrast-induced liver cancer. On the basis of the above findings, early detection of liver dysfunction offers a possibility of early diagnosis of primary liver cancer.

Conditions associated with hepatocellular carcinoma.

The most important condition associated with hepatocellular carcinoma is chronic hepatitis B virus infection. This article summarizes the information linking hepatocellular carcinoma with conditions other than hepatitis B virus infection.

The epidemiology and morphology of primary malignant liver tumors.

The ubiquitous problem of cirrhosis may be complicated by the development of primary liver cell carcinoma, with rates of incidence so high in certain parts of the world as to make it a candidate for the most common cancer in humans. When cirrhosis reaches the macronodular stage, the risk of developing liver cell carcinoma increases, and at this point liver cell dysplasia may be seen in biopsy. Alcoholics, who classically have a micronodular cirrhosis, may attain the macronodular pattern through better clinical management, abstinence, and longer survival. Hepatitis B-related cirrhosis, on the other hand, is most often macronodular. Recent DNA hybridization studies strongly favor a viral role in oncogenesis, and this possibility is supported by the serologic and epidemiologic evidence complied in the last decade. Liver cell malignant tumors tend to recapitulate the characteristics of normal liver, namely, growth in cords, uniformity of cytologic appearances, and bile production, but also present distinctive histologic and immunohistochemical patterns that are unique to a malignant liver cell population. The other primary malignant tumors of the liver, arising in bile ducts, blood vessels, and mesenchymal elements, all carry their individual epidemiology and morphology, but in general invoke, as does liver cell carcinoma, the concept of a series of step by step cell-carcinogen and cell-carcinogen interactions by which normal cells give rise to malignant populations.
