  • Effect on Microvessel Density and Vascular Endothelial Growth Factor Expression of Radiofrequency Ablation with Arsenious Acid on Liver VX2 Tumors

    Objective To evaluate the effect on microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression of combining radiofrequency ablation (RFA) with arsenious acid (AA) locally treating liver VX2 tumor in rabbits. Methods Twenty-eight New Zealand White rabbits with implanted liver VX2 tumors were randomly divided into four groups, control group (n=7), AA group (n=7), RFA group (n=7) and combination (RFA+AA) group (n=7). All rabbits were killed 14 days after treatment. MVD and VEGF expression were examined by immunohistochemistry. Results The MVD degraded one by one in control group,AA group,RFA group and RAF+AA group, which were (38.50±0.44), (23.07±0.47), (18.65±0.39) and (11.36±0.36)/HP respectively, compared while each two groups, P<0.05. The VEGF expression also degraded one by one, the ratio of positive cases were 7/7, 5/7, 4/7 and 2/7 respectively, compared while each two groups, P<0.05. There was positive correlation between VEGF expression and MVD (Person conefficient of product-moment correlation r=0.47, P<0.01). Conclusion Combining RAF with AA therapy can greatly decrease MVD and VEGF expression of tumor tissue.
