中晚期宫颈癌血管介入治疗61例应用

[目的]探讨超选择性髂内动脉插管化疗对中晚期宫颈癌的疗效.[方法]经皮股动脉穿刺插管.在数字减影血管造影下(DSA),对61例(81例次)中晚期宫颈癌进行超选择性髂内动脉及肿瘤供血动脉插管化疗,其中20例宫颈癌患者介入前后使用流式细胞仪进行DNA含量(DI)测定和S期细胞比率(SPF)以及细胞凋亡的检测,另30例宫颈癌患者介入前后取宫颈活检组织检测核仁组成区嗜银蛋白(AgNOR)、增殖细胞核抗原(PCNA)的表达.[结果]介入治疗近期有效率为78.7%,症状缓解有效率为88.5%,手术治疗46例,栓塞组术中出血量明显低于未栓塞组(P＜0.05);介入化疗后的DI、SPF均显著低于化疗前(P＜0.05);介入化疗后的AgNOR颗粒数目减少、直径增大(P＜0.05),介入化疗后PCNA的积分减少(P＜0.05).[结论]①中晚期宫颈癌经超选择性血管介入治疗获得根治手术机会明显增加;动脉化疗-栓塞治疗效果优于动脉化疗;提示未经治疗的宫颈癌患者为血管介入化疗最佳适应证.②介入化疗能降低其DNA含量和S期细胞比率,抑制宫颈癌细胞增殖,诱导细胞凋亡,抑制肿瘤的恶性进展.③超选择性髂内动脉插管化疗为一种微创、可重复进行、安全、有效的治疗措施.

The Application of Superselection Internal Ilia Artery Catheterization Chemotherapy(SIAC) in 61 Cases of Advanced Cervical Carcinoma

To investigate the efficacy of superselection internal ilia artery catheterization chemotherapy(SIAC)in advanced cervical carcinoma.SIAC with Seldinger catheterization and DSA was performed in16cases(81times)with advanced cervical carcinoma.Using flow cytometry,we determined DNA content and S-phase fraction(SPF)and apoptosis in cervical carcinoma pre-and postchemotherapy.Short-term response rate was78.7%.Symptom remission rate was88.5%.Forty-six cases received operation following SIAC.The amount of bleeding during operation was significantly lesser in embolized group than that in non-embolized group.[Conclusion]The superselection internal ilia artery catheterization chemotherapy can apparently increase the chance of operation in advanced cervical carcinoma.SIAC is a new,safe and effective treatment.
