非小细胞肺癌体部立体定向放射治疗的质量管理

摘要

目的:完善非小细胞肺癌患者体部立体定向放射治疗(stereotactic body radiotherapy,SBRT)的质量控制和管理,提高治疗精度.方法:针对我院2014年1月至2016年4月期间临床确诊的30例行SBRT治疗的非小细胞肺癌患者,回顾性分析CT模拟定位,靶区勾画,治疗计划评估,剂量验证,治疗摆位验证,完成治疗过程中的质量管理.结果:通过严格的质量管理,减少了患者治疗过程中的误差,危及器官受量均在限定范围内,摆位误差小于等于3 mm.结论:通过完善非小细胞肺癌SBRT的质量管理,可提高治疗精度.%Objective:To improve the quality control and management of SBRT in the treatment of non-small cell lung cancer(NSCLC)patients and to improve the precision of treatment.Methods:30 cases of NSCLC underwent SBRT in our hospital from January 2014 to April 2016 by clinical diagnosis confirmed.The data of CT simulation,tar-get delineation,treatment planning assessment,dose verification,treatment setup verification and treatment process of quality management were analyzed retrospectively.Results:Through strict quality management,reduce the error in the process of patient treatment,endanger organs are within the scope of the qualified,setup error is less than or equal to 3 mm.Conclusion:The quality management process will improve the accuracy of SBRT treatment,and reduce side effects.
