Detection of Hepatocellular Carcinoma During a Clinical Follow-up of Chronic Liver Disease: Observations in 31 Patients

In 31 patients with an initial diagnosis of cirrhosis or chronic hepatitis hepatocellular carcinoma (HCC) was detected after a clinical follow-up of 8 months to 14 years with an average of 59 months. They had had no scintigraphic and biochemical abnormalities suggestive of HCC at the beginning. The follow-up period before the detection of carcinoma was shorter in patients positive for hepatitis B surface antigen compared with those negative for hepatitis B surface antigen. Analyses of clinical data during the follow-up and liver scans made shortly before tumor detection suggested that in most of these patients HCC became discernible relatively early in the course of cirrhosis or long before cirrhosis reached an advanced stage. A sharp rise in serum alpha-fetoprotein level proved highly diagnostic in 11, it remained low throughout in 7, and tumor was already unresectable in the majority. Although continuous and regular check for alpha-fetoprotein is imperative in patients with chronic liver disease, particularly in those with hepatitis B surface antigenemia, additional diagnostic tools are necessary for the detection of small HCC in its resectable stage.
