125I粒子食管支架治疗食管癌临床应用的研究进展

食管癌是常几尢的恶性肿瘤，大部分患者确诊时已属晚期，失去外科手术机会。食管支架近年来被广泛应用于食管癌造成的食管狭窄的治疗，临床应用表明食管支架可以有效地解决患者的吞咽困难，但普通支架对肿瘤本身无任何治疗作用。^125I粒子食管支架的出现则弥补了这一不足，其在扩张食管的同时对肿瘤进行近距离的放射治疗，从而达到解决患者吞咽困难和抑制食管肿瘤的双重目的。现对^125I粒子食管支架的研究进展及临床应用作一综述。

Clinical application of esophageal stent loaded with 125I seeds: recent progress in research

Esophageal cancer is a common malignant tumor. Most patients have already in the late stage of the disease when the diagnosis is confirmed and have lost the surgery chance. In recent years, esophageal stent has been widely applied in the treatment of esophageal stenosis caused by esophageal cancer. The clinical experience shows that the esophageal stent can effectively solve the problem of dysphagia. However, the ordinary esophageal stent has no therapeutic effect on the esophagus tumor. The esophageal stent loaded with ~(125)I seeds can not only solve the dysphagia problem but also can treat the primary esophagus cancer with its brachytherapy effect. This article aims to review the clinical application and the up-to-date research progress of the esophageal stent loaded with ~(125)I seeds.
