摘要 目的探讨脑转移瘤放疗后放射性脑坏死发病的风险因素。方法研究脑转移瘤放疗后放射性脑坏死的风险因素。从2014年12月至2018年12月,应用加速器治疗的脑转移瘤患者36例(68个靶点)。治疗后运用核磁影像学来复查,由三位核磁诊断医生根据患者病史及影像学表现来诊断放射性脑坏死。采用Logistic回归分析糖尿病、心脑血管病、计划靶区体积、分割次数、分割剂量,是否有脑部放疗史,是否联合全脑照射、生物效应剂量与放射性脑坏死的关系;采用ROC曲线测定所有影响因素对放射性脑坏死的预测价值。结果共有4个靶点(11.54%)发生放射性脑坏死。回归分析显示计划靶区体积的大小是放射性脑坏死发病的风险因素。ROC曲线显示曲线下面积为0.737。结论计划靶区体积的大小是脑转移瘤放疗后放射性脑坏死的风险因素。
