摘要 目的 :了解影响鼻咽癌放疗预后的主要因素 ,寻找提高鼻咽癌放疗疗效的途径。方法 :病理证实为鼻咽癌的初治病人 113例 ,放射源为60 Co治疗机的γ射线 ,以肿瘤情况为依据 ,以常规设野为主 ,采用常规分割方式照射 ,放疗后每 2~ 6个月定期复查、随访 ,持续 4年。结果 :全组 1~ 4年总的生存率分别为 98 2 %、86 4%、79 3 %、69 9%。Cox回归结果提示 :病理类型与预后关系不大 ;TNM分期能反映远期预后 ;性别、年龄、放射源、剂量分割和鼻咽设野方式、个体对放射的敏感性、近期放疗疗效等因素与远期疗效有关。结论 :选择合理的放射源、注意放疗中的时间剂量分割、改进放射野的设计、提高摆位的准确性 ,是提高鼻咽癌远期疗效的途径。
