【摘要】 目的 评估125I粒子串近程放射治疗兔植入性门静脉主干癌栓(MPVTT)的安全性和有效性。方法 对32只新西兰大白兔门静脉主干植入VX2肿瘤细胞株,随机分为治疗组(T组,n=16)和对照组(C组,n=16)。治疗组、对照组兔MPVTT中分别植入125I粒子串、无放射性粒子串,术后定期监测兔一般情况、体重、实验室检查变化,术后2周治疗组、对照组各处死8只兔,作病理学检查。余下兔饲养至死亡作尸检,对比两组多层螺旋CT检查结果、组织病理学检查结果、Ki- 67标记指数、凋亡指数,并以此为基础评估该疗法的有效性。结果 近程放射治疗后每个观察时间点均表明,对照组兔体重下降更加明显,两组兔肝功能、血细胞计数差异均无统计学意义(P>0.05)。治疗组、对照组平均MPVTT体积为分别为(565.4±220.9) mm3、(2 269.9±437.0) mm3,差异有显著统计学意义(P<0.001);Ki- 67蛋白指数分别为(4.14± 1.84)%、(33.82±6.07)%,凋亡指数分别为(6.51±1.92)%、(0.91±0.26)%,差异均有显著统计学意义(P=0.001);平均生存时间分别为(39.50±2.37) d、(27.38±1.22) d, 差异有显著统计学意义(P=0.001)。结论125I粒子串近程放射治疗兔植入性MPVTT安全有效。
