Eight cases were treated with periodic arterial infusion therapy from reservoir and four cases with arterial infusion therapy plus 30 Gy's radiation therapy for hepatocellular carcinoma (HCC). The anatomical extent of the tumor was E3 and E4, respectively. We evaluated these forms of therapy from the viewpoint of tumor characteristics, survival time and therapeutic effects. There was no effective case of life prolongation and most of the reservoir only treated cases died a short time after therapy. But no severe complication was observed in reservoir plus radiation cases. One case showed a response, and another case tumor necrosis. The results indicate that this method is effective for advanced HCC.
