目的 对鼻咽癌进行放疗,探讨影响五年生存率的因素。方法 1990年5月～1992年5月首程根治放疗鼻咽癌80例,5年随诊率为93.7％。结果 疗后5年生存率为36.25％,Ⅱ期病例5年生存率高,生存率与性别、年龄和病理类型无关,与病期有明显关系。单纯外照射病例5年生存率和加用~(192)Ir后装治疗的病例5年生存率两者比较无显著差异。ⅢⅣ期病例鼻咽颅底剂量以70Gy以上为宜。
Objective To radiotherapy of nasopharyngeal carcinoma to explore the factors that affect the five-year survival rate. Methods From May 1990 to May 1992, 80 cases of nasopharyngeal carcinoma were treated by radical radiotherapy in the first episode. The 5-year follow-up rate was 93.7%. Results The 5-year survival rate was 36.25%. The 5-year survival rate of stage Ⅱ patients was high. The survival rate was not related to sex, age and pathological type, and had a significant relationship with the disease stage. There was no significant difference between the 5-year survival rate of patients with simple external irradiation and the 5-year survival rate of patients treated with ~ (192) Ir. Ⅲ Ⅳ stage nasopharyngeal skull base dose to more than 70Gy appropriate.
