Abstract

Transcatheter arterial chemoembolization(TACE) is an imperative method for the managment of inoperable hepatocellular carcinoma(HCC). It is well known that primary HCC frequently invades the portal venous system and forms a tumor thrombus obstructing the portal blood flow which makes unfavorable prognosis of patiebt. We retrospetively reviewed 58 patients who reveived TACE(minimum 3 times) of HCC invading into portal venous system. Group 1(n=29) which showed peripheral portal vein invasion had better clinical and laboratory response. Group 2(n=17) which showed first order portal branch invasion had similar response to Group 3(n=12), which had main portal invasion. Group 1 showed no difference in survival time between TAC and TACE, but, in Group 2 and 3, emboliation with chemotherapy made longer survival than chemotherapy only. Clinical level of AFP was meaningful in Group 1 and 2 as decreasing value. Our results provides that careful selection of TACE and case by case Coil/Gelfoam embolization can improve the mean survival and clinical response when HCC evidently invades portal venous system.
