目的探索放射性~(125)I粒子支架治疗中、晚期食管癌的可行性、安全性及初步疗效。方法根据患者病变的大小通过治疗计划系统(treatment plan system,TPS)计算出放射粒子的剂量,放射性粒子准确固定在支架外侧,选择21例食管癌患者,临床分期均为Ⅲ~Ⅵ期,将支架植入患者食管内并进行临床随访。结果21例患者的内照射支架均释放到位,释放过程顺利,释放过程中未出现125I粒子脱落现象。术后2个月胸部CT复查病变厚度和体积较术前有所缩小18例,病变增大3例。2例患者分别于术后4、5个月死亡。术后6个月复查胃镜示19例患者未出现如食管穿孔、出血等并发症,未出现支架移位,未出现食管再狭窄情况。结论粒子支架治疗中晚期食管肿瘤是既能杀灭肿瘤,不良反应又小的方法,短期疗效较好,临床初步应用是安全有效的。
Objective To explore the feasibility, safety and primary efficacy of radioactive 125 I stent in the treatment of advanced esophageal cancer. Methods The doses of radioactive particles were calculated by the treatment plan system (TPS) according to the size of the lesion and the radioactive particles were fixed on the outside of the stent. Twenty-one patients with esophageal cancer were selected. The clinical stage was stage Ⅲ-Ⅵ. Implanted in patients with esophageal and clinical follow-up. Results All the 21 cases of internal scaffolds were released in place and the release process was successful. No 125I particles shedding occurred during the release. 2 months after the chest CT review lesion thickness and volume reduced compared with preoperative 18 cases, lesions increased in 3 cases. Two patients died 4,5 months after surgery. Six months after operation, gastroscopy showed no complications such as esophageal perforation and hemorrhage in 19 patients. There was no stent displacement and esophageal restenosis. Conclusion Particle stents in the treatment of advanced esophageal neoplasms is both a method of killing tumors and having a small adverse reaction. The short-term curative effect is good and the preliminary clinical application is safe and effective.
