摘要 [目的]评价三维适形放疗肺癌患者的临床资料和放疗计划的物理参数,评估临床、物理指标与放射性肺炎的关系。[方法]回顾性分析36例发生放射性肺炎的肺癌患者,并配以同期治疗的36例未发生放射性肺炎患者作为对照组,比较两组三维适形治疗计划的剂量体积直方图(DVH)及临床资料。观察包括年龄、性别、病理、临床分期、肿瘤位置、化疗、肺部疾病史放疗剂量等临床指标,及DVH上获取的包括两肺V5、V10、V15、V20、V25、V30、V35、V40、V45及Dmean、GTV体积、两肺容积等物理参数。比较这些因素对放射性肺炎发生率的影响。[结果]放射性肺炎发生时间,8例于放射治疗中,28例于放射结束后0~9个月。中位时间为3.5个月。单因素分析显示物理指标两肺V5、V10、V15、V20、V25、V30、V35、V40及Dmean,临床指标吸烟和合并化疗与放射性肺炎发生率相关,而患者年龄、临床分期、病理类型、是否合并肺部基础疾病等与放射性肺炎的发生无明显关系。多因素分析显示仅有V5与放射性肺炎相关。[结论]评估肺癌治疗计划时,要充分考虑两肺V5、V10、V15、V20、V25、V30、V35、V40及Dmean等物理学指标,合并化疗及吸烟患者更应该严格控制正常肺组织受量。而V5是预测放射性肺炎的独立指标。
