于１９９３年１０月至１９９４年１２月，选取在我院行放射治疗的病理确诊的Ⅰ～Ⅳａ期初诊鼻咽癌病人６４例，按Ｔ、Ｎ、Ｍ配对分为对照组（单纯面颈分野组）和实验组（综合面颈联合野＋面颈分野，采用低熔点铅挡块组）进行临床治疗观察，放疗后２～３月临床和ＣＴ检查结果显示，实验组鼻咽原发灶基本消退率５９．３７％明显高于对照组的３１．２５％，两组差别有统计学意义（Ｐ＜０．０５）。急性放射反应方面，实验组皮肤反应、口腔口咽粘膜反应、进食困难和胃肠反应均轻于对照组，两组差别统计学有显著意义（Ｐ＜０．０５）
From October 1993 to December 1994, 64 patients with newly diagnosed nasopharyngeal carcinoma diagnosed by radiotherapy in our hospital from January to April were selected and divided into control group (simple facial and neck separation) according to T, N and M pairs Group) and experimental group (comprehensive face-neck joint field + face-neck separation, the use of low melting point lead block group) for clinical treatment, 2 to 3 months after radiotherapy clinical and CT examination results show that the experimental group of primary nasopharyngeal basic The regression rate of 59.37% was significantly higher than that of the control group (31.25%), the difference between the two groups was statistically significant (P <0.05). In acute radiation reaction, the skin reaction, oral oropharyngeal mucosa reaction, eating difficulty and gastrointestinal reaction in the experimental group were lighter than those in the control group, with significant difference between the two groups (P <0.05)
