收集５５７例鼻咽癌以随机分组联合应用地龙、复方丹参、野木瓜进行放射增敏的前瞻性研究。近期疗效结果显示，不管放疗结束时原发灶的全消中还是放疗后３个月鼻咽ＣＴ扫描复查原发灶的全消率，中药放疗组均优于对照组，Ｐ＜０．００５。但颈淋巴结转移灶的全消率两组之间无明显差异，Ｐ＞０．５。同时还讨论了以上３种中药放射增敏的机理。 A total of 557 cases of nasopharyngeal carcinoma were randomly divided into two groups: Radix Scutellariae, Radix Salviae Miltiorrhizae and Radix Puerariae. Radiographic sensitization was performed prospectively. Recent results show that, regardless of the end of radiotherapy in the total elimination or radiation 3 months after nasopharyngeal CT scan to review the primary rate of the whole area, the Chinese radiotherapy group were better than the control group, P <0.005. However, there was no significant difference between the two groups in the rate of cervical lymph node metastasis (P> 0.5). Also discussed the above three kinds of Chinese medicine radiosensitization mechanism.
