摘要
目的探讨放射性125Ⅰ粒子植入治疗结肠直肠癌肝转移(CRLM)的疗效及安全性。方法为24例化疗失败或不能耐受化疗的CRLM患者共计65个肝转病灶行CT引导下植入125Ⅰ粒子,粒子的放射性活度介于0.5~0.7 mCi,每例患者接种的粒子数为18~109枚,最小边缘剂量为110~160 Gv植入后进行质量验证。结果在6个月的随访中,肿瘤的最长径基线和从术前(7.21±3.28)cm降到术后3个月时的(4.47±3.34)和6个月时的(3.94±2.05)cm,差异有统计学意义(P<0.05)。CEA南术前的(293±89)ng/ml降至术后3、6个月的(198±103)ng/ml、(155±6 1)ng/ml,差异有统计学意义(P<0.05)。未出现与治疗相关的死亡。1、2年生存率分圳为87.5%和75.0%。结论 CT引导下125Ⅰ粒子植入治疗CRLM微创、安全,近期疗效确切,远期疗效有待观察。
