肿瘤的放射治疗是一种利用放射源产生的高能射线或者医疗设备产生的X射线、电子束、质子束和粒子束等来破坏肿瘤生长或杀死肿瘤细胞的治疗方法。自从肿瘤放疗被应用到临床以后,此方法一直被当做是治疗恶性肿瘤的最有效的方法之一。放疗增敏方法和增敏药物一直是肿瘤放疗研究的热点,其中,热疗作为一种辅助治疗肿瘤的手段,在肿瘤的放化疗中得到了越来越广泛的应用。肿瘤热疗是利用加热的方式治疗肿瘤,利用热能在组织中的生物学作用,使肿瘤组织升至有效治疗温度(40~44℃)并维持一定的时间,引起肿瘤细胞的生长受阻或凋亡,而又不损伤正常细胞的一种方法,此方法能够缓解患者的疼痛,提高患者的生活质量[1]。本文从放疗联合热疗的角度探讨放疗的热增敏机制及其临床应用。
