鼻咽癌治疗失败原因主要为局部复发和远处转移,这与临床病期有一定关系,但无特异性。目前国内外学者探讨能预测放射效应,微核定量检测是其中方法之一。本文分析鼻咽癌组织照射前后微核率的变化及其与局部控制的关系。 1 材料与方法 1.1 鼻咽癌组织来源于鼻咽部活检,病理证实,均为低分化鳞癌。按长沙分期,Ⅲ期9人,Ⅳ期4人。采取标本后,除去正常组织,生理盐水冲洗,分成二部
The main reason for the failure of nasopharyngeal cancer treatment is local recurrence and distant metastasis, which is related to the clinical stage, but it is not specific. At present, domestic and foreign scholars discuss the ability to predict radiation effects, and micronucleus quantitative detection is one of the methods. This article analyzes the change of micronucleus rate before and after irradiation of nasopharyngeal carcinoma tissue and its relationship with local control. 1 Materials and Methods 1.1 Nasopharyngeal cancer tissue derived from nasopharyngeal biopsy, pathologically confirmed, are poorly differentiated squamous cell carcinoma. According to the Changsha phase, there are 9 people in phase III and 4 in phase IV. After taking the specimen, remove the normal tissue, rinse with saline and divide it into two parts.
