目的 分析 6 0 Co外照射加高剂量率腔内后装放疗治疗鼻咽癌的疗效 ,局部控制率及放射并发症。方法 :回顾性分析 1989年 5月～ 1996年 3月采用 6 0 Co外照射加高剂量率腔内后装放疗鼻咽癌 30例。结果 本组病例总的近期局部控制率为 73.33% (2 2 / 30 ) ,无瘤生存率为 6 0 %转移11例 ,无一例发生晚期放射并发症。结论 腔内后装放疗鼻咽癌 ,可提高局部控制率 ,适应于鼻咽癌早期及鼻咽癌外照射后鼻咽腔内残留病灶。
Objective To analyze the curative effect, local control rate and radiation complications of the treatment of nasopharyngeal carcinoma with 60 Co external irradiation and high dose rate lumpectomy. Methods: From May 1989 to March 1996, 30 patients with nasopharyngeal carcinoma were irradiated with high dose of 60 Co external radiation after radiation therapy. Results The total recent local control rate was 73.33% (2 2/30) in this group of patients, and the tumor-free survival rate was 60% in 11 cases. None of the patients had late radiation complications. Conclusion The posterior luminal radiotherapy of nasopharyngeal carcinoma can improve the local control rate and adapt to the nasopharyngeal residual tumor in the early stage of nasopharyngeal carcinoma and nasopharyngeal carcinoma after external irradiation.
