The increased incidence of bone metastasis in hepatocellular carcinoma in the decade 1988-1997 is first attributed to the prolonged survival rate of hepatocellular carcinoma patients due to recent progress in both the diagnosis and treatment of the disease. Dissemination of hepatocellular carcinoma cells to the vertebra through the portal vein-vertebral vein plexuses due to the presence of portal thrombus and/or portal hypertension may be related to a higher incidence of bone metastasis in hepatocellular carcinoma. Both an early diagnosis and timely treatment of bone metastases are thus called for in the follow-up of hepatocellular carcinoma patients.
