The efficacy of transarterial immuno-embolization therapy (TIE) was investigated in 7 patients with multiple hepatocellular carcinoma (HCC). We administered OK-432 (10 KE), fibrinogen (30 mg/ml) and thrombin (1 U/ml) as a new treatment for HCC with intrahepatic metastasis. In all patients with a high level of AFP, the AFP level decreased promptly less than the pretreatment level after TIE therapy. High fever in all cases, epigastralgia in 6 cases and appetite loss in 3 cases were observed after TIE therapy. Our results indicate that this therapy may be a safe and effective method in HCC patients with intrahepatic metastasis.
