放射治疗是恶性肿瘤治疗的重要手段之一,随着其应用的日益广泛,人们在注重疗效的同时,也更加关注射线所导致的不良反应。在进行恶性肿瘤的放射治疗时,往往更多的是观察其对血常规的影响,是否发生放射性胃肠炎、肺炎和皮肤损伤,而忽略了其对骨组织的影响。有关放射性骨损伤的研究结果指出,骨组织受到射线照射后出现(临床发现)骨损伤的时间为2.4~10.0年[1]。Schmeler等[2]研究发现骨组 Radiation therapy is one of the important means of malignant tumor treatment. As its application is more and more widespread, people pay more attention to the curative effect and pay more attention to the adverse reactions caused by radiation. In radiotherapy of malignant tumors, often more is to observe its impact on the blood routine, whether the occurrence of gastroenteritis, pneumonia and skin damage, while ignoring its impact on bone tissue. The results of the study on radiation-induced bone damage indicate that the time (clinically discovered) for bone damage after radiographic irradiation of bone tissue is 2.4 to 10.0 years [1]. Schmeler et al [2] found that bone group
