摘　　要：目的 调查粤东地区放疗物理技术及QA的基本情况,为促进基层单位放疗学科建设、资源合理配置提供参考。方法 2016年3—5月利用互联网技术结合现场调查方式,对粤东地区放疗单位的一般情况、设备配置、开展技术和治疗QA方面进行了调查和统计分析。结果 截止2016年5月31日,共有放疗单位8家,开放病床数966张,日均放疗632人次,放疗从业人员222人。共有直线加速器12台,后装治疗机5台,γ刀1台,CT模拟机8台,放疗计划系统9套。5个单位开展包括IMRT/VMAT、IGRT、ART技术,精确放疗计划除1个单位外治疗前全部进行剂量验证。直线加速器、CT模拟机、后装治疗机等设备QA项目存在缺漏,专业技术人员职业培训以短期进修及老带新为主。结论 调查显示粤东地区放疗资源配置处于较低水平。地区内各单位放疗技术及QA存在明显差距,需加强放疗QA规范的建立和执行,重视专业技术人员的职业培训。Objective To investigate the physics technique and quality assurance （QA） during radiotherapy in the institutions from the East Guangdong province, aiming to provide reference for the construction of radiotherapy discipline and rational allocation of resources in the primary hospitals from the eastern Guangdong province. Methods From March 15 to May 20, 2016, the general conditions, radiotherapy equipment, available technique and quality assurance （QA） in the medical institutions from eastern Guangdong were investigated and analyzed by online combined with on-spot surgery. Results There were 8 institutions which provided radiotherapy with 966 ward beds, a daily capacity of 632 patients and 222 radiotherapy practitioners. Radiotherapy equipment included 12 linear accelerators, 5 after-loading devices, 1γ-knife, 8 CT simulators and 9 radiotherapy planning systems. Five institutions performed IMRT/VMAT, IGRT and ART. Dose verification was performed before precision radiotherapy delivery in all institutions except for 1 center. QA procedures were missing for the linear accelerators, CT simulators and after-loading devices. Short-term advanced studies and hand-by-hand teaching were the main approaches for staff professional training. Conclusions The resource allocation for radiotherapy in the medical centers from the eastern Guangdong province is scarce. The technique and QC levels greatly differ among different institutions. Standard QA protocols are urgently to be established and implemented. Extensive attentions should be paid to the the professional training for technicians.
