    Abstract:
    The behavior of an anti-cancer drug consisting of transcatheter hepatic segmental arterial chemoembolization using Lipiodol mixed with an anti-cancer drug followed by gelatin sponge (segmental Lp-TAE: Seg-Lp-TAE) was assessed in comparison to that of the non-segmental Lp-TAE to whole liver (Lp-TAE) by means of Tc-99m pertechnetate (RI). Injection of Lipiodol mixed with Adriamycin and 740 mBq of RI followed by gelatin sponge was carried out from segmental or subsegmental hepatic artery in 12 cases of hepatocellular carcinoma and from proper or right hepatic artery in 11 cases (9 with hepatocellular carcinoma and 2 with metastatic liver tumor). The distribution and retention of RI were studied from the time activity curves of ROIs in tumor and non-tumor area, and scintigrams at 4 and 24 hours after injection. The integral value ratio of tumor to non-tumor was significantly higher in Seg-Lp-TAE, indicating that es the distribution of RI after Seg-Lp-TAE is selective in the segments where tumor exists. In Seg-Lp-TAE, the T1/2 was higher and the count ratio of tumor to non-tumor was significantly higher at 4 hours and even higher at 24 hours after injection. These results suggest that an anti-cancer drug reinforces the effect on tumor with little adverse effect on normal liver in Seg-Lp-TAE, which is more advantageous to the treatment of hepatocellular carcinoma.
