[Arterial infusion chemotherapy and embolization in unresectable hepatocellular carcinoma using an intraarterial...

We performed arterial infusion chemotherapy and embolization on 22 patients with unresectable hepatocellular carcinoma via an intraarterial catheter, which was inserted in the hepatic artery under laparotomy. The administration frequency of intraarterial chemotherapy on a patient was 1 to 155 with a median of 17, while that of embolization was 1 to 6 with a median of 2.5. The maximal and average durations of a catheter in place were 15 and 4 months, respectively. The survival rates were 50% in one year, 18% in two years, and 12% in three years. Insertion technique and management of the catheter are relatively safe and easy, so catheterization of the hepatic artery would enable us to develop new treatment modalities.
