[Therapeutic effects by implantable infusion pump for hepatic malignant tumors]

Chemotherapy and chemoembolization using implantable infusion pump were performed in fifteen cases of hepatocellular carcinoma (HCC) and one case of cholangioma. The following results were obtained; (1) Complete response (CR) was obtained in two cases (12.5%) and partial response (PR) in three cases (18.8%) with HCC. (2) Tumor thrombus in the portal vein disappeared in two of four cases with HCC. (3) The followup period ranged from 54 to 768 days and administration from one to 33 times. These results suggest that good therapeutic effects and quality of life can be obtained by implantable drug delivery system.
