经左锁骨下动脉留置导管肝动脉化疗栓塞加灌注治疗结直肠癌肝转移疗效观察

目的评价经左锁骨下动脉留置导管肝动脉化疗栓塞加灌注治疗内科化疗无效的结直肠癌肝转移患者临床价值。方法50例结直肠癌肝转移患者均采用经左锁骨下动脉留置导管肝动脉化疗栓塞加灌注,共介入治疗124周期,化疗方案为奥沙利铂＋5-氟尿嘧啶,栓塞剂采用超液化碘油。所有患者每次介入治疗前均行增强CT测量肿瘤大小,检测肿瘤标记物（CEA,CA199,CA724）。采用RECIST标准评价疗效,Kaplan-Meier计算生存率。结果本组患者完全缓解（CR）2例（4%）,部分缓解（PR）15例（30%）,病变稳定（SD）10例（20%）,病变进展（PD）23例（46%）,总有效率（CR＋PR）34%（17例）。1年生存率82%,2年生存率30%。从诊断肝转移始中位生存期38个月,从介入治疗始中位生存期22个月,中位无进展生存期10个月。结论经左锁骨下动脉留置导管肝动脉化疗栓塞加灌注是治疗内科化疗无效结直肠癌肝转移患者的有效方法。
