Primary liver cell carcinoma. Clinical features.

The clinical features of 77 patients with primary liver cell carcinoma seen over a nine-year period were examined. Eighty per cent of the patients had underlying cirrhosis, of alcoholic origin in most cases. In nine of the patients hepatitis B surface antigen was found in the serum; all nine patients were born in areas where hepatitis B virus infection is endemic. Abdominal pain and ascites were the most common presenting symptoms; they are due mainly to the locally invasive nature of the tumour. A confirmatory laboratory finding in the diagnosis is the observation of raised alkaline phosphatase levels and the presence of alpha-fetoprotein in the serum. The diagnosis should be established without performing a laparotomy and should seriously be considered in a previously stable patient with cirrhosis who deteriorates clinically without obvious cause.
