~(125)I粒子联合5-氟尿嘧啶缓释化疗粒子植入治疗晚期胰腺癌疗效观察

目的:观察125I粒子联合5-氟尿嘧啶缓释化疗粒子植入治疗晚期胰腺癌的疗效。方法:12例无法切除晚期胰腺癌患者于术中先植入5-氟尿嘧啶缓释化疗粒子,再植入放射性125I粒子。其中,放射性125I粒子源强为0·4mCi~0·5mCi,肿瘤周边匹配剂量为60Gy~100Gy,平均每例使用125I粒子16粒和5-氟尿嘧啶1000mg。结果:疼痛均得到缓解,止痛有效率为91·7%;瘤体均有不同程度缩小,局部控制率为83·3%;1y生存率为25%。结论:125I粒子联合5-氟尿嘧啶缓释化疗粒子植入治疗晚期胰腺癌方法简单、安全、有效。

Implantation of 125I Particles plus 5-FU Slow-release Particles for Advanced Pancreatic Cancer

OBJECTIVE:To observe the clinical effects of interstitial implantation of 125 I particles together with5-FU slow-release particles for advanced pancreatic cancer.METHODS:A total of12patients with advanced pancreatic cancer whose tumors were unsuitable to be resected were implanted with5-FU slow-releasing particles and then 125 I particles.The intensity of radioactive 125 I particles was0.4mCi～0.5mCi,the matched peripheral dose was60Gy～100Gy,and an average of16 125 I particles and1000mg5-FU were used for each patient.RESULTS:Relief of pain was achieved in all the subjects,with the effective rates of odynolysis at91.7%.The tumor size in all the subjects was diminished to some degree,with local control rate at83.3%.1y survival rate was25%.CONCLUSION:Interstitial implantation of 125 I particles and5-FU slow-release particles for advanced pancreatic cancer is simple,safe and effective.
