[Effect of dibutyryl cyclic AMP in the treatment of hepatocellular carcinoma--intraarterial infusion therapy combined with anticancer agent for hepatocellular carcinoma with portal vein thrombosis].

Dibutyryl cyclic AMP was administered to 7 cases with hepatocellular carcinoma and its tumor thrombosis in portal vein, combined with intraarterial infusion of Mitomycin C or Adriamycin with implanted reservoir. Among these cases, tumor regressed in 5 cases, and therapeutic effect on tumor thrombosis was observed in 4 cases. The median survival time after initial treatment was about 5 months in 5 cases of Vp3, and more than 18 months in 2 cases of Vp2. Reduction of liver dysfunction by cholinesterase and hepaplastin test was found in most cases, and no severe side effects were observed. It is suggested that dibutyryl cyclic AMP has an antitumor effect on hepatocellular carcinoma, especially on its tumor thrombosis in portal vein, and also may assist in recovery from liver dysfunction.
