Key Points 1. Outcome from nonsurgical treatment is directly related to stage of hepatocellular cancer (HCC) and degree of liver function impairment. 2. Ablative percutaneous procedures, such as alcohol injection or radiofrequency thermal therapy, are most effective in the destruction of solitary tumors of 3 cm or less. 3. In most cases, nonsurgical treatments are not curative, but may slow tumor progression and can provide palliation. 4. Arterial embolization or chemoembolization has an antitumor effect, but it has not been shown to affect patient outcome. 5. Radiation therapy, chemotherapy, hormonal manipulation, and interferon have not been consistently effective in HCC. 6. Ablative procedures, embolization, and systemic chemotherapy should be avoided in patients with advanced cirrhosis.
