１９９４年５月至１９９５年４月将９８例初治鼻咽癌配对分为腔内微波热疗合并放疗（简称热疗）组与单纯放疗（简称单放）组各４９例。间接鼻咽镜与ＣＴ近期疗效评价，热放组鼻咽原发灶完全消退率分别为９５．９２％与６８．８９％，单放组为８３．６７％与４６．６７％（Ｐ＜０．０５），热放组肿瘤缩小１／２与完全消退放射剂量均较单放组明显降低。疗效与加热温度，热疗次数有关，同时亦发现热放组颈淋巴结转移灶完全消退率较单放组高。 From May 1994 to April 1995, 98 cases of newly diagnosed nasopharyngeal carcinoma were divided into four groups, 49 cases in each group, which were treated by intracavitary microwave hyperthermia combined with radiotherapy (referred to as hyperthermia) and radiotherapy alone (referred to as single radiotherapy). Indirect nasopharyngoscopy and CT evaluation of immediate effect, radiotherapy group nasopharyngeal complete remission rates were 95.92% and 68.89%, 83.67% and 46.67% (P <0 .05), heat shrinkage group tumor shrinkage 1/2 and complete remission radiation dose were significantly lower than the single release group. Efficacy and heating temperature, the number of hyperthermia, and also found that heat release group neck lymph node metastasis complete remission rate higher than the single group.
