[Multidisciplinary therapy of hepatocellular carcinoma--TAI. TAE treatment by intra-arterial catheterization].
Two hundred sixty-six cases of hepatocellular carcinoma (HCC) were treated between June 1980 and October 1985 (4 years and 4 months) at our hospital. Hepatectomy was performed in 118 patients, 82 of which had received transcatheter arterial embolization with iodized oil (Lipiodol) 58 of then with an intraarterial catheter. HCC tumors were often multiple when they were combined with liver cirrhosis and smaller than 3 cm in diameter. For this reason treatment of HCC by surgery alone has limitations for prolongation of life. A multidisciplinary treatment is therefore necessary. We have found hepatectomy and transarterial embolization to be the most effective treatment for HCC. In order to perform repeated embolizations after hepatectomy, we developed a heparinized catheter with notches to permit safe fixation. This is suitable for long-term intraarterial use. While previous arterial catheters only permitted infusion of drugs due to their small diameters, our new catheter can be used for embolizations with Lipiodol and Gelfoam and for angiography. It is inserted through the right gastroepiploic artery into the gastroduodenal artery so that its tip lies at the level of the hepatic artery. It is brought out through the abdominal skin and flushed at two-week intervals with heparin-urokinase. The indications for the use of the catheter have been repeated embolizations 1) for prevention of tumor recurrence (surgical adjuvant therapy), and 2) after absolutely non-curative operations. For the first indication, we have found that multiple tumors and tumors larger than 5 cm frequently recur within 1 year after surgery. We have, since July 1983, used the catheter treatment to prevent recurrence in 30 such cases. Embolization with Lipiodol + Adriamycin followed by Gelfoam cubes is performed at three-month intervals for one year after surgery, starting one month after surgery, as a rule. The preliminary results indicate an improved survival rate after the treatment.
