局部增温已成为治疗恶性肿瘤的措施之一。增温对癌细胞的直接作用经过近年来的反复研究已被确定。但癌症的彻底治疗除了依靠外力杀伤大部分恶性细胞外,还有赖于机体的防御功能最后清除残留的少量恶性细胞。我们以往的实验研究证明,全身增温可以使X线的抑瘤效应增强,并提示此作用可能与增温对宿主免疫功能的影响有 Local warming has become one of the measures to treat malignant tumors. The direct effect of warming on cancer cells has been determined after repeated studies in recent years. However, in addition to relying on external forces to kill most of the malignant cells, a thorough treatment of cancer also depends on the defensive function of the body to remove the residual small amounts of malignant cells. Our previous experimental studies have demonstrated that systemic warming can enhance the X-ray tumor suppressor effect and suggest that this effect may be related to the effect of warming on host immune function.
