[Vanishing tumor thrombus in IVC after oral administration of UFT and TAE in a patient with HCC; a case report].

A 74-year-old man was diagnosed as hepatocellular carcinoma (HCC) in the area of S6-7 with tumor thrombus continuously developed from hepatic vein to inferior vena cava (IVC). AFP value remained high despite two transcatheter arterial embolizations with adriamycin, mitomycin and Lipiodol (Lp-TAE). The AFP value gradually decreased two weeks after oral administration of UFT. Nine months after, the AFP level was 26.4 ng/ml and the tumor thrombus in the IVC disappeared. The size of the main tumor did not change. This case suggests Lp-TAE and UFT are useful for suppressing the growth of the main tumor and to extinguish the tumor thrombus.
