摘要
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。
Purpose On observation of inside-bronch-channel encroachment using high-dose rate intracavitary radiotherapy in treating lung cancer. Methords We selected sixteen patients with advanced lung cancer of inside-bronch-channel encrochment. Under the guidance of tracheobrone hoscopy ,the applicator was placed at the target area and connected with SK- Ⅱsystem. The total dose was short-range after-loading 20Gy(5Gy , once a week ). Result .The tumors of twelve cases disappeared and the bronchi were unobstructed. The tumor of four cases became less and the bronchial diameter became larger. The total effective rate was 100 %. Conclusion High-Dose rate intracavitary radiotherapy in treating lung cancer with inside-bronch-channel encroachment could eliminate obstruction and alleviate symptom. The methord is a simple , secure and effective.
