目的：探讨和比较三种不同放疗方法对鼻咽癌的疗效。方法：将120例鼻咽癌随机分为3组，每组40例，A组连续放疗，B组超分割放疗，C组分段放疗。结果：5年生存率3组相仿，但超分割组和分段组在减少放射后遗症和劳动能力恢复方面优于连续放疗组。结论：超分割和分段放疗对于鼻咽癌生存者的生存质量的提高是有益的。
Objective: To explore and compare the efficacy of three different radiotherapy methods on nasopharyngeal carcinoma. Methods: 120 cases of nasopharyngeal carcinoma were randomly divided into 3 groups, 40 cases in each group, group A continuous radiotherapy, group B hyperfractionation radiotherapy, group C radiotherapy. Results: The 5-year survival rates were similar in 3 groups, but the over-segmentation group and sub-group were better than continuous radiation group in reducing radiation sequelae and labor ability recovery. CONCLUSIONS: Hyperfractionation and segmented radiotherapy are beneficial for improving the quality of life of NPC patients.
