≥3个金标追踪在射波刀治疗中的优势比较

目的 分析不同数量的金标在射波刀放疗中的区别,阐述金标追踪在射波刀临床治疗中的优势。方法 整理和分析2013—2014年间进行射波刀金标追踪治疗的患者424例,其中观察组330例(≥3个金标追踪),对照组94例(<3个金标追踪),记录并分析每例患者的摆位误差数据和治疗误差数据。结果 观察组摆位误差平均值0.031 mm,治疗误差平均值0.314 mm;对照组摆位误差平均值0.057 mm,治疗误差平均值1.122 mm。结论 采用≥3个金标追踪能明显提高患者的治疗精确度,提高治疗质量。

Advantages of tracking no less than three gold markers in radiotherapy with CyberKnife

Objective To analyze the differences between CyberKnife radiotherapy with different numbers of gold markers.Methods A total of 424 patients undergoing CyberKnife with gold markers from 2013 to 2014 were enrolled and analyzed.In these patients,330 patients with no less than 3 gold markers were assigned to observation group and 94 patients with less than 3 gold markers were assigned to control group.The setup error and treatment error were recorded and analyzed for each patient.Results The mean setup error and mean treatment error were 0.031 mm and 0.314 mm in the observation group and 0.057 mm and 1.122 mm in the control group,respectively.Conclusion Tracking no less than 3 gold markers can substantially improve the accuracy and quality of treatment.
