由于局部解剖特点致鼻咽部恶性肿瘤的早期诊断较难,且病理组织学类型大多分化较低、易于复发及转移,故文献报告放疗后五年生存率仅15～40%。本文报导对207例经病理证实的鼻咽部恶性肿瘤放疗后疗效观察。患者男103、女104,年龄由14～70岁,就诊时属Ⅰ～Ⅱ期39名(19%)、Ⅲ期134名(65.6%)、Ⅳ期35名(15.4%)。152名(73.4%)患者有颈淋巴结转移。109例仅接受外照射,98例尚辅以腔内照射。放疗后生存五年以
Due to the local anatomical features of nasopharyngeal malignant tumors is difficult to diagnose early, and most of the histological types of low differentiation, easy to recurrence and metastasis, so the literature reports the survival rate after radiotherapy only 15 to 40%. This article reports 207 cases of pathologically confirmed nasopharyngeal malignant tumors after radiotherapy. Male 103 and female 104 were aged 14 to 70 years old. They were 39 (19%) from stage Ⅰ to Ⅱ, 134 (65.6%) in stage Ⅲ and 35 (Ⅳ) in stage Ⅳ (15.4%). 152 (73.4%) patients had cervical lymph node metastases. 109 cases received only external irradiation, 98 cases were supplemented by intracavitary irradiation. Survival after radiotherapy for five years
