    Abstract:
    Transcatheter arterial embolization (TAE) by using degradable starch microspheres (DSM) as embolic material, 40 microns in diameter and degraded by serum amylase within one hour, was carried out for thirteen cases with hepatic malignancies including eleven cases with hepatocellular carcinoma (HCC), one case with cholangiocarcinoma and one case with metastatic liver cancer. DSM were mixed with anticancer agents and administered through the catheter, which was introduced by Seldinger's method, via the hepatic artery immediately after hepatic angiography in ten cases and through subcutaneously implanted drug delivery system (Port-A-Cath) in three cases. The dose of DSM was 900 mg/body and adriamycin 30-40 mg/m2 or 12-14 mg/m2 were used. The former was administered through the catheter immediately after angiography and the latter through Port-A-Cath for HCC and cholangiocarcinoma. A same dose of DSM and mitomycin C 15-16 mg/m2 was administered for metastatic liver cancer through the catheter immediately after angiography. The administration was repeated weekly in three cases in which Port-A-Cath was implanted, and at five weeks' interval through the catheter immediately after hepatic angiography in the other ten cases. Therapeutic effects were assessed and pharmacokinetics of adriamycin were studied. Results were as follows; 1) Partial response (PR) was obtained in five cases out of eleven cases with HCC (45.5%) and there were three cases with minor response (MR) in the other six cases. Totally, decrease of tumor size was demonstrated in eight cases out of eleven cases (72.7%). 2) In nine cases in which AFP was positive, the titer of AFP was decreased in seven cases (77.8%). 3) No change (NC) was obtained in cholangiocarcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)
