１９７６～１９９２年首程根治放射治疗鼻咽癌３１９例。１、３、５、１０年存活率分别为８０．９％、６４．１％、５８．１％、３０．５％。Ⅰ、Ⅱ期病人生存质量及生存率明显高于Ⅲ、Ⅳ期。影响预后的主要因素为病期及放射剂量，病期早生存率高。鼻咽癌放射剂量应在６０～７０Ｇｙ６～７周为宜。其它因素如年龄，病理类型，临床表现与生存率无关。建议鼻咽癌耳前野后界向后移动０．５～１ｃｍ，使后界垂直外耳孔或外耳孔后缘，避免咽后壁、咽旁间隙肿瘤复发。
The First Radical Radiotherapy of 319 Cases of Nasopharyngeal Cancer from 1976 to 1992. The survival rates at 1, 3, 5 and 10 years were 80.9%, 64.1%, 58.1% and 30.5% respectively. The quality of life and survival rate of stage Ⅰ and Ⅱ patients were significantly higher than those of stage Ⅲ and Ⅳ. The main factors that affect the prognosis are the stage of disease and radiation dose, early stage of disease rate is high. Nasopharyngeal carcinoma radiation dose should be 60 ~ 70Gy6 ~ 7 weeks is appropriate. Other factors such as age, pathological type, clinical manifestations and survival rate has nothing to do. Proposal nasopharyngeal carcinoma ear field backwards move 0.5 ~ 1cm, so that the posterior boundary of the external ear hole or the posterior edge of the ear, to avoid the pharyngeal wall, parapharyngeal space tumor recurrence.
