    Abstract:
    OBJECTIVES: To evaluate 3-dimensional conformal radiotherapy (3D-CRT) of unresectable hepatocellular carcinoma (HCC) patients for whom transcatheter arterial chemoembolization (TACE) was ineffective or unsuitable, and to determine whether tumor response and portal vein thrombosis (PVT) response to treatment were prognostic factors for overall survival. METHODS: From July 2001 to June 2005, 70 unresectable HCC patients were treated with 3D-CRT; PVT was present in 41 patients. A daily radiation dose ranging from 2 to 3 Gy was administered using 6 or 15 MV x-rays to deliver a total dose between 44 and 54 Gy. RESULTS: Of 70 patients, follow-up computed tomography showed that primary tumor responses were complete response (CR) in 4 (5.7%) patients, partial response (PR) in 34 (48.6%), no response (NR) in 28 (37.1%), and progressive disease (PD) in 4 (8.6%). Of 41 patients with PVT, PVT responses were CR in 4 (9.7%) patients, PR in 12 (29.3%), NR in 20 (48.8%), and PD in 5 (12.2%). The median survival times were 18.0 and 20.1 month in the primary tumor and the PVT responders (CR + PR), respectively, which were longer than the 6.8 and 7.2 months in the primary tumor and the PVT nonresponders (NR + PD), respectively. CONCLUSIONS: 3D-CRT was associated with a 54.3% objective response rate for primary tumors and a 39.0% objective response rate for PVT. Both primary tumor and PVT responses were found to be prognostic factors for overall survival. The present results suggest 3D-CRT is a practical treatment option in HCC patients for whom TACE is ineffective or unsuitable.
