不同病人正常组织的放射反应性存在着明显差异,虽然宿主因素(如,年龄、贫血、糖尿病、高血压等)和治疗相关参数(剂量或治疗方案)被认为对其有影响,但目前仍未证实这些因素能改变组织的放射反应性。如果这些差异是由于个体间细胞的内在放射敏感性不同所造成的,那么在病人的正常组织反应性和肿瘤放射敏感性之间很有可能存在一定的联系。已有许多作者对此做过一些回顾性分析,但 There are significant differences in the radioactivity of normal tissues in different patients, although host factors (such as age, anemia, diabetes, hypertension, etc.) and treatment-related parameters (dose or treatment plan) are considered to have an effect on it, but they are still not present. Confirm that these factors can change the organization’s radioactivity. If these differences are due to differences in the intrinsic radiosensitivity of cells between individuals, there is probably a certain link between the patient’s normal tissue reactivity and the tumor’s radiosensitivity. Many authors have done some retrospective analysis, but
