Study of survival amongst a group of 101 patients with epithelial tumours of the nasopharynx treated by cobalt irradiation between 1967 and 1972 indicates the prognostic significance of the following factors: the histological type, extension of the tumour, the degree of lymph node involvement, age and sex. The optimal dose is 1,800 to 2,000 rets NSD and should be modified in the light of these factors, and above all the histological type and the tumour category. Cumulative survival for all cases was 36% at 5 years, with a more favourable prognosis in lympho-epitheliomas in comparison with spindle cell epitheliomas.
对1967年至1972年间接受钴照射治疗的101例鼻咽上皮肿瘤患者的生存情况研究表明，以下因素具有预后意义：组织学类型、肿瘤范围、淋巴结受累程度、年龄和性别。最佳剂量为1800至2000拉德的肿瘤剂量（NSD），应根据这些因素进行调整，尤其是组织学类型和肿瘤类别。所有病例的5年累积生存率为36%，淋巴上皮瘤的预后比梭形细胞上皮瘤更有利。
