BACKGROUND: Surgical resection is generally accepted as the first choi
ce of treatment for hepatocellular carcinoma (HCC). However, due to it
s multifocal nature, association with chronic liver disease, and frequ
ent postresectional recurrence, nonresectional therapies are important
in the management of a significant proportion of patients with HCC. D
ATA SOURCES: A literature review was performed on the current status o
f different nonresectional treatment modalities commonly employed for
HCC. They include direct ablation methods, systemic chemotherapy, tran
scatheter arterial chemoembolization, external and targeting radiother
apy, hormonal therapy, and immunotherapy. Multidisciplinary therapy re
sulting in preoperative cytoreduction has also been reported with impr
ovement of therapeutic results. CONCLUSION: Nonresectional therapies p
lay an essential role in the treatment of inoperable HCC as they lead
to satisfactory survival. Percutaneous ethanol injection and transcath
eter arterial chemoembolization are the most frequently employed modal
ities, and they result in a 3-year survival rate of 55% to 70% and abo
ut 20%, respectively. Multidisciplinary therapy appears to be the curr
ent trend of management and improved survival is achieved especially w
hen unresectable tumors are converted to resectable ones. (C) 1997 by
