本文收集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率还是放疗后３个月鼻咽ＣＴ扫描复查原发灶的全消率，中药组均优于对照组Ｐ＜０．００５。但颈淋巴结转移灶的全消率两组之间没有明显差异Ｐ＞０．５。本文还讨论了这３种中药放射增敏的机理问题。 This article collected 557 cases of nasopharyngeal carcinoma randomized to the combined application of earthworm, compound salvia miltiorrhiza, wild papaya for radiosensitization prospective study. Recent efficacy results showed that regardless of the total elimination rate of the primary tumor at the end of radiotherapy or the total elimination rate of the primary lesion after 3 months of radiotherapy for nasopharyngeal CT scan, the Chinese medicine group was superior to the control group P<0.005. However, there was no significant difference between the two groups in the total elimination rate of cervical lymph node metastases (P>0.5). This article also discusses the mechanism of radiosensitization of these three kinds of traditional Chinese medicines.
