辐射基因治疗在肿瘤治疗中的研究现状
Current Status of Tumor Radiogenic Therapy
-
摘要: 目前肿瘤基因治疗尚存在许多问题, 距临床应用还有相当的距离, 但是在传统的放疗、化疗和手术治疗的基础上, 辐射与基因治疗的有机结合在肿瘤治疗中却显示出可喜的前景。综述了近年来这一领域的研究进展, 探讨了这一疗法对肿瘤治疗的应用前景。
Although tumor gene therapy has a distance to clinical use due to some problems, the combination of irradiation and gene therapy holds much promise in cancer therapy based on the traditional radiotherapy, chemotherapy and surgery. We have termed this therapeutic radiogenic therapy. This review focuses on the group of radiogenic therapy that are either： ⑴ improvement of gene transfer efficiency by irradiation; ⑵ radiotherapy combined with cytokines gene delivery or enhancement of the immunity of tumor cells by transgene; ⑶ directly stimulated by radiation to produce either directly or indirectly cytotoxic agents; ⑷ increasing of radiosensitivity in gene therapy; ⑸ radioprotective gene therapyenhances radiation tumor killing effect while protecting the normal tissue and organs with transgene using transfer vector.
