介入性灌注化疗与热灌注化疗对兔VX2肝癌模型的作用比较研究

Effect of interventional thermochemotherapy on VX2 transplanted hepatic tumor model:a comparative study with interventional chemotherapy in experimental rabbits

目的观察热灌注化疗对兔VX2肝癌模型疗效及安全性。方法新西兰大白兔20只,制备兔肝VX2模型,随机分为对照组(A)和实验组(B),分别A组给于常温(22～25℃)5%葡萄糖100ml+5-Fu(20mg/kg),B组给于60℃5%葡萄糖100ml+5-Fu(20mg/kg),用B超观察处理前后肿瘤大小,抽血查ALT变化。结果A组肿瘤体积由(1627±473)mm3缩小为(1334±641)mm3,B组肿瘤体积由(1682±397)mm3缩小为(1130±559)mm3,两组差别有统计学意义(P<0.05);ALTA组由(755±203)u/L增加为(834±262)u/L,B组由(781±197)u/L增加为(865±237)u/L,组间差异无统计学意义。结论介入性热灌注化疗比常温灌注化疗对兔VX2肝癌模型有更高的抑制作用。

Objective To evaluate the effectiveness and safety of interventional thermochemotherapy for VX2 transplanted hepatic tumor model in experimental rabbits.Methods The hepatic tumor model was established in 20 New Zealand rabbits by implanting VX2 tumor cells into the right hepatic lobes of the rabbits.The rabbits were randomly and equally divided into two groups with 10 rabbits in each group：group A （study group）and group B（control group）.Via the femoral access,the catheter was placed into the tumor-feeding artery,which was confirmed by DSA.The rabbits in group A received an infusion of 100 ml 5% glucose plus 5-Fu（20 mg/kg）at 60℃temperature,while the rabbits in group B received an infusion of 100 ml 5%glucose plus 5-Fu（20 mg/kg）at normal room temperature（22-25℃）.Before and after the procedure,the tumor size was measured by means of B ultrasonography and the serum ALT was estimated to assess the liver function.The results were statistically compared between two groups.Results After the treatment,the tumor size in group A（study group）became much smaller than that in group B（control group）,with P0.05.And no significant difference in the serum ALT level existed between group A and group B.Conclusion The interventional thermochemotherapy is superior to interventional chemotherapy in inhibiting VX2 transplanted hepatic tumor in experimental rabbits.
