放射治疗是继手术治疗后应用最广泛的肿瘤治疗方法之一,技术已经比较成熟,但长期以来,各种肿瘤的辐射抗性以及放疗过程中造成的肿瘤临近部位正常组织的损伤,一直制约着肿瘤放疗疗效与应用。基因治疗是目前肿瘤治疗的研究热点之一。目前更加实际的策略,就是与现有治疗手段相结合。基因治疗通过沉默异常细胞信号、DNA修复,促进免疫监视及细胞凋 Radiation therapy is one of the most widely used cancer treatments following surgical treatment. The technology has been relatively mature. However, for a long time, the radiation resistance of various tumors and the damage of normal tissues near the tumor caused by radiotherapy have been restricted Therapeutic effect and application of tumor radiotherapy. Gene therapy is currently one of the hot topics in cancer therapy. The current more practical strategy is to combine the existing treatment. Gene therapy by silencing abnormal cell signaling, DNA repair, and promote immune surveillance and apoptosis
