摘要
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 analyse the results and local control rate of nasopharyngeal carcinoma treated by 60 Co external irradiation plus high dose rate afterloading intracavity radiation(AIR). Methods:From May 1989 to March 1996,30 patients with nasopharyngeal carcinoma were treated by 60 Co external irradiation dose varied from 50-70Gy whereas AIR dose ranged from 10-20Gy. Results:All patients were followed up.The local control rate was 93.33%,disease free rate was 60%,the 1、2、3、4 year actuarial survival were 100%,93.33%,73.33%,50%,1 case recurred in the nasopharynx and 11 cases developed distant metastase,no late radiation complication was found. Conclusion:AIR for nasopharyngeal carcinoma is indicated for local control and for residual disease after primary external radiotherapy.
