在肿瘤的治疗中,放射治疗的效应有很大的局限性。其原因之一,在于细胞具有修复辐射诱发损伤的能力。因此,近年来人们努力寻求某些可以增强辐射作用的途径及药物,从而提高放射治疗率。目前这些常用的途径主要有合并使用高温(hype-rthermia),以及合并应用某些干扰DNA 代谢的药物,诸如阿霉素,放线菌素等。 In the treatment of tumors, the effects of radiation therapy have great limitations. One of the reasons for this is that cells have the ability to repair radiation-induced damage. Therefore, in recent years, people have endeavored to seek certain ways and drugs that can enhance the radiation effect, thereby increasing the radiotherapy rate. At present, these commonly used pathways include the use of hype-rthermia and the combined use of certain drugs that interfere with DNA metabolism, such as doxorubicin and actinomycin.
