目的 探讨经肾动脉栓塞化疗治疗不能切除的晚期肾癌的疗效及意义。方法 30例肾癌患者 ,Robson分期ⅢB～ⅣB,均已失去手术机会 ;经肾动脉行碘油药物乳剂、明胶海绵颗粒和弹簧钢圈栓塞化疗。结果 所有患者症状减轻甚至消失 ,食欲、体重增加 ;12例生存 3a以上 (40 % ) ,6例生存 5a以上 (2 0 % )。结论 经肾动脉栓塞化疗是不可切除的晚期肾癌首选的姑息疗法 ,碘油药物乳剂、明胶海绵颗粒和弹簧钢圈三者结合是肾癌较佳的栓塞材料。
Objective To investigate the efficacy and significance of transcatheter arterial chemoembolization in the treatment of unresectable advanced renal cell carcinoma. Methods 30 patients with renal cell carcinoma, Robson stage ⅢB ~ ⅣB, have lost the chance of surgery; the renal artery via lipiodol drug emulsion, gelatin sponge particles and spring steel embolization chemotherapy. Results All patients had relieved or even disappeared of symptoms, appetite and weight gain; 12 patients survived more than 3a (40%) and 6 patients survived more than 5a (20%). Conclusion Renal artery embolization chemotherapy is the first choice of palliative treatment for unresectable advanced renal cell carcinoma. The combination of lipiodol emulsion, gelatin sponge particles and spring steel ring is the best embolization material for renal cell carcinoma.
