目的高剂量率腔内放射治疗肺癌腔内侵犯疗效观察。方法选择肺癌腔内侵犯患者１６例，经纤维支气管镇插入后装治疗管，与ＳＫ－Ⅱ型近距只后装治疗机连接进行放疗。剂量为每ｄ５Ｇｙ，每周１次，共照４次。结果纤维支气管镜检查示肿瘤消退，管腔通畅１２例，癌肿部分消退，管腔增宽４例。总有效率１００％。结论高剂量率腔内放射治疗肺癌腔内侵犯，可快速消除梗阻，缓解症状，是一种简单、安全、有效的治疗方法。
Objective To observe the curative effect of high dose rate intraluminal radiotherapy for intraluminal invasion of lung cancer. Methods A total of 16 patients with intraluminal invasion of lung cancer were selected. The tube was inserted into the tube after being inserted into the fiber bronchial area and connected with a SK-II proximal post-loading therapy machine for radiotherapy. The dose is 5 gy per d, once a week, for a total of 4 shots. RESULTS: Fiberoptic bronchoscopy showed tumor regression, 12 lumen patency, partial resection of cancer, and widened lumen in 4 cases. The total efficiency is 100%. Conclusion High-dose rate intraluminal radiotherapy for intracranial invasion of lung cancer can quickly eliminate obstruction and relieve symptoms. It is a simple, safe and effective treatment.
