Purpose: The purpose of this study was to determine the potential role of three-dimensional conformal radiotherapy (3D-CRT) in the treatment of primary unresectable hepatocellular carcinoma. The preliminary results on the efficacy and the
toxicity of 3D-CRT are reported.

Materials and Methods: Seventeen patients were enrolled in this study, which was conducted prospectively from January 1995 to June 1997. The exclusion criteria included the presence of extrahepatic metastasis, liver cirrhosis of Child-Pugh
classification C, tumors occupying more than two thirds of the entire liver, and a performance status of more than 3 on the ECOG scale. Two patients were treated with radiotherapy only while the remaining 15 were treated with combined
transcatheter
arterial chemoembolization. Radiotherapy was given to the field including the tumor plus a 1.5 §¯ margin using a 3D-CRT technique. The radiation dose ranged from 36¡­60 §í (median; 59.4 §í). Tumor response was based on a radiological examination
such as
the CT scan, MR imaging, and hepatic artery angiography at 4¡­8 weeks following the completion of treatment. The acute and subacute toxicities were monitored.

Results: An objective response was observed in 11 out of 17 patients, giving a response rate of 64.7%. The actuarial survival rate at 2 years was 21.2% from the start of radiotherapy (median survival; 19 months). Six patients developed a
distant
metastasis consisting of a lung metastasis in 5 patients and bone metastasis in one. The complications related to 3D-CRT were gastro-duodenitis (¡Ã grade 2) in 2 patients. There were no treatment related deaths and radiation induced
hepatitis.

Conclusion: The preliminary results show that 3D-CRT is a reliable and effective treatment modality for primary unresectable hepatocellular carcinoma compared to other conventional modalities. Further studies to evaluate the definitive
role
of
the 3D-CRT technique in the treatment of primary unresectable hepatocellular carcinoma are needed.
