To compare the antitumor efficacy and safety of transcatheter arterial chemoembolization (TACE) by epirubicin suspension (epirubicin suspension: epirubicin-iodized oil mixture without solution) to that by epirubicin emulsion (epirubicin emulsion: epirubicin-iodized oil mixture with solution), the efficacy of treatment by administration of either an epirubicin suspension or emulsion was examined in an animal model. Changes in plasma epirubicin concentration were compared over 24 h immediately after treatment, and enhanced ultrasonographic and histopathological analysis subsequently conducted 7 days after treatment to determine the growth ratio and proportion of viable tumor cells. The growth ratio and proportion of viable tumor cells were found to be significantly lower in the suspension group than in the emulsion group while the plasma epirubicin concentration was found to be significantly higher in the suspension group than in the emulsion group. These results indicate that administration of an epirubicin suspension is a superior form of TACE compared to that of administration of an epirubicin emulsion.

AbstractTranscatheter arterial chemoembolization (TACE) is a standard treatment for unresectable hepatocellular carcinoma; however, it does not always result in tumor control. Nevertheless, treatment outcome can be improved with monodisperse emulsions of anticancer agents. In this study, the efficacy and safety of a monodisperse miriplatin-Lipiodol emulsion were evaluated in Japanese white rabbits. VX2 tumor was implanted into the left liver lobe of each rabbit. The animals were divided into control and experimental groups (of five animals each) and respectively administered a conventional miriplatin suspension or the emulsion via the left hepatic artery. Computed tomography (CT) was performed before, immediately after, and two days following TACE. All rabbits were sacrificed two days after the procedure. Each tumor was removed and cut in half for assessment of iodine concentration in one half by mass spectroscopy and evaluation of Lipiodol accumulation and adverse events in the other half. Mean Hounsfield unit (HU) values were measured using plain CT images taken before and after TACE. Iodine concentration was higher in the experimental group [1100 (750–1500) ppm] than in the control group [840 (660–1800) ppm]. Additionally, the HU value for the experimental group was higher than that for the control group immediately after [199.6 (134.0– 301.7) vs. 165.3 (131.4–280.5)] and two days after [114.2 (56.1–229.8) vs. 58.3 (42.9–132.5)] TACE. Cholecystitis was observed in one rabbit in the control group. Ischemic bile duct injury was not observed in any group. The results show that Lipiodol accumulation and retention in VX2 tumor may be improved by using a monodisperse emulsion. Moreover, no significant adverse events are associated with the use of the emulsion.

4541 Background/Aim: Although transcatheter arterial chemoembolization (TACE) has been widely used for the treatment of unresectable hepatocellular carcinoma (HCC), the optimal indication of the TACE has not been fully elucidated. Methods: The treatment outcomes after TACE were analyzed retrospectively to determine predictive factors of anti-cancer effect on HCC. The patient (pts) selection criteria were: 1) admission between 1992 and 2005, 2) diagnosis of fresh HCC, 3) no extrahepatic metastasis and 4) primary treatment with TACE. TACE was performed by selectively introducing a catheter into the hepatic artery and injecting gelatin sponge particles following an emulsion consisting of 2–5 ml of iodized oil (Lipiodol) and 20–50 mg doxorubicin hydrochloride. Lipiodol accumulation in tumors was regarded as an indication of necrosis. We defined complete response (CR) as disappearance or 100% necrosis of all tumors, and partial response (PR) as more than 50% reduction and/or more than 50% necrosis. Results: There were 270 pts who fulfilled the above criteria. According to Japan Integrated Staging, the number of T1, T2, T3 and T4 was 10, 59, 171 and 30, respectively. There were 52 CRs, 113 PRs, 77 who remained SD and 28 who showed PD/NE. The median survival months of CR, PR, SD and PD/NE were 50, 30, 15 and 5, respectively, and there was a significant differences between them. The logistic regression analysis revealed tumor multiplicity and vascular invasion (VI) were significantly associated with the objective response (CR or PR). The response probability of patients with solitary tumor without VI was 85%, that with multiple tumors without VI was 63%, that with solitary tumor with VI was 33% and that with multiple tumors with VI was 16%. The small tumor (<5 cm) was another favorable factor which was significantly associated with CR. Among 231 patients without VI, the CR probability of patients with a solitary tumor <5 cm or >5 cm was 46% or 40%, respectively; although that of those with multiple tumors <5cm or >5cm was 21% or 5%, respectively. Conclusion: TACE is recommended for HCC patients without VI, and is optimally indicated for those with a solitary tumor or those with multiple tumor <5 cm among them.
