Abstract
PURPOSE: To evaluate the antitumor effects of transcatheter arterial chemoembolization (TACE) with a solution of an anticancer drug (Paclitaxel; Bristol-Myers Squibb, Princeton, NJ) and iodized oil (Lipiodol; Laboratoire Gurerbet, Aulnay-Sous-Bois, France) (hereafter, the solution), as well as intratumor concentration and hepatotoxicity, in experimentally induced liver tumor. MATERIALS AND METHODS: VX2 carcinoma was grown in livers of 30 rabbits. In 18 rabbits, TACE was performed with the high-dose solution (4 mg anticancer drug the low-dose solution (I mg anticancer drug and 0.4 n = 6) and 0.4 mL iodized oil,, mL iodized oil, n = 6), or iodized oil alone (0.4 mL, n = 6) in a control group. One week later, the growth ratio and residual viable proportion of the tumors were calculated on the basis of findings at spiral computed tomography and histopathologic examination. Hepatic and hematologic toxicities were evaluated by means of Differences between the three groups were statistically assessed with the Kruskal-Wallace and Mann-Whitney U tests. The remaining 12 animals were treated with the high-dose solution and serially sacrificed for clarification of chronologic change of concentration of the anticancer drug in liver tissues. RESULTS: Growth ratios and residual viable proportions of the tumors were significantly lower in the solution groups (high dose, 3.3% +/- 6.2 [mean +/- SD] and 2.8% +/- 3.6, respectively; low dose, 18.7% +/- 7.4 and 12.7% +/- 6.1, respectively) than in the control group (68.3% +/- 12.7 and 31.1% +/- 8.8, respectively) (P < .05). Hepatotoxicity was transient in all but one rabbit, which died 2 days after TACE with substantial biochemical changes. The anticancer drug accumulated in tumor where the concentration peaked at day 3 and returned to levels comparable to those for normal hepatic parenchyma at 7 days after TACE. CONCLUSION: TACE with the Paclitaxel-Lipiodol solution has dose-dependent antitumor effects without major toxicities in VX2 liver tumor. (C) RSNA, 2003.
