该文针对临床上分割放疗,因肿瘤的再氧合,限制了乏氧细胞增敏剂的应用时,热疗加MISO 能否增敏的问题进行了动物实验。作者指出,不论单纯一次X 线治疗或分割治疗在与MISO 或加温或这两个因素同时应用时,治疗结果均有提高。在放疗中加用热疗可以提高疗效已 In this paper, animal experiments were conducted to determine whether radiotherapy plus MISO could increase sensitization when the radiotherapy of hypoxic cells was limited due to tumor reoxygenation. The authors point out that treatment results are improved when either a single X-ray treatment or segmentation therapy is applied concurrently with MISO or warming or both. Adding hyperthermia in radiotherapy can improve the efficacy
