摘要:
目的研究5-FU缓释微球经胃十二指肠动脉灌注对兔VX2肝肿瘤的治疗作用。方法将成功接种肝VX2肿瘤的模型兔随机分成4组,每组10只,用显微外科手术临时阻断肝总动脉血流,经胃十二指肠动脉插管至肝固有动脉起始部给药行介入治疗,术毕结扎胃十二指肠动脉。A组(生理盐水对照组),注射生理盐水0.5~1ml ;B组(碘佛醇对照组)注射碘佛醇0.5~1ml ;C组为碘油组(疗效对比组),注射超液化碘油0.5~1.0ml ;D组为5-FU缓释微球组,注射5-FU缓释微球10mg 和碘佛醇1ml 混合溶液。4组实验动物于治疗1周后观察肿瘤生长情况、坏死程度,并采用原位末端标记法(TUNEL)检测肿瘤细胞凋亡指数(AI)。结果治疗1周后5-FU缓释微球组肿瘤生长受到抑制,肿瘤生长率低于生理盐水对照组和碘佛醇对照组(P﹤0.05),与碘油组差异无统计学意义(P>0.05)。4组肿瘤均有不同程度坏死,5-FU缓释微球组和碘油组肿瘤坏死率明显高于另两组(P<0.05)。生理盐水对照组、碘佛醇对照组和5-FU缓释微球组肿瘤细胞凋亡指数分别为1.69±0.18、1.75±0.27和8.03±0.63,5-FU缓释微球组与各对照组相比差异有统计学意义(P<0.05)。结论5-FU缓释微球经动脉灌注可抑制肝肿瘤生长,诱导肿瘤细胞凋亡,促进肿瘤坏死,是有效的化疗栓塞剂。
