ABSTRACT
<p><b>OBJECTIVE</b>To investigate the anticancer efficacy and the hepatic and renal toxicity of As2O3-lipiodol emulsion via transarterial embolization in a rabbit VX2 liver tumor model.</p><p><b>METHODS</b>VX2 tumors were implanted in rabbit livers successfully, followed by transarterial embolization with high-dose As2O3(5 mg/kg with 0.2 mL lipiodol, n=10), low-dose As2O3(1 mg/kg with 0.2 mL lipiodol, n=10), and control(0.2 mL lipiodol, n=10). The growth ratios and microvessel densities(MVDs) of the tumors were estimated by multi-row spiral CT and CD34 immunohistochemical staining, respectively. Hepatic and renal function was also evaluated by means of blood biochemical analysis.</p><p><b>RESULTS</b>The growth ratios of the tumors differed significantly among three groups(P<0.01). The high-dose and low dose group showed significantly lower tumor growth ratios[44.05%(-36.40%~64.60%), 95.20%(-11.60%~159.40%)] than control group[145.55%(98.90%~250.30%), all P<0.05]. The MVDs of the tumors were significantly lower in the high-dose(21.4±10.6) and low-dose group(34.1±12.0) than those in control group(57.9±16.1,all P<0.05). The levels of blood ALT and AST obtained 28 days after transarterial embolization were significantly lower in the high-dose[(25.50±12.37)U/L,(24.25±10.89)U/L] and low-dose group[(45.00±14.04)U/L,(35.22±11.86)U/L] than in control group[(79.12±30.52)U/L,(75.25±25.89)U/L, all P<0.05].</p><p><b>CONCLUSION</b>As2O3-lipiodol emulsion via transarterial embolization has anticancer effect without significant hepatic and renal functional damage in rabbit VX2 liver tumors.</p>
