目的 研究CT立体定向囊腔内放疗治疗儿童囊性颅咽管瘤的有效性和安全性。方法 对 2 6例囊性颅咽管瘤进行CT立体定向囊腔、胶体磷酸铬内治疗。结果 全部病例经手术排除囊液后临床症状迅速改善 ,经囊腔内放疗 ,1～ 5年随访。CT扫描显示 2 2例 (84.6 % )瘤腔持续消失 ,2例 (7.7% )瘤腔显著缩小 ,症状持续改善。 2例 (7.7% )分别于 1、3年后因瘤实质部分增大 ,症状恶化而相继死亡。无手术死亡和严重并发症。结论 CT立体定向囊腔内放疗治疗儿童囊性颅咽管瘤安全、有效 ,可作为治疗儿童囊性颅咽管瘤首选的方法
Objective To study the efficacy and safety of CT stereotactic radiotherapy in the treatment of cystic craniopharyngioma in children. Methods Twenty-six cystic craniopharyngiomas were treated with CT stereotactic cyst and colloidal chromium phosphate. Results All patients were treated with cyst fluid to exclude the clinical symptoms of rapid improvement after intracavitary radiotherapy, 1 to 5 years follow-up. CT scan showed disappearance of the tumor cavity in 22 cases (84.6%), tumor cavity reduction in 2 cases (7.7%), and continuous improvement of symptoms. Two cases (7.7%) died one after the other one to three years, respectively, due to the fact that the tumor mass increased and the symptoms deteriorated. No operative deaths and serious complications. Conclusion CT stereotactic radiotherapy for cystic craniopharyngioma in children is safe and effective and can be used as the preferred method for the treatment of cystic craniopharyngioma in children
