Objective To conduct the 7th investigation by Chinese Society of Radiation Oncology,Chinese Medical Association,and to further investigate the current situation of radiotherapy in mainland China,reasonably allocate personnel and equipment resources,and promote the development of radiotherapy in China.Methods From October 8,2015 to December 2015,the office for investigation of radiotherapy information was established,the list and contact information of radiotherapy units were provided by each province,and a special data submission system was used for a complete,rapid,and efficient investigation through the Internet.Results As of January 20,2016,there were 1 413 radiotherapy units in the mainland China with 52,496 employees in total,among which there were 15 839 radiotherapy physicians (4824 with senior professional titles),8 452 technical therapists (260 with senior professional titles),3 292 physicists (562 with senior professional titles),and 938 maintenance engineers (120 with senior professional titles).In the aspect of radiotherapy equipment,there were 1930 linear accelerators,96 Co-60 teletherapy units,173 X-knife units,212 γ-knife units,382 Ir-192 brachytherapy units,436 Co-60 brachytherapy units,1 051 X-ray simulators,1 353 CT simulators,642 MRI simulators,978 sets of multileaf collimators,1922 sets of treatment planning systems,and 974 sets of radiotherapy network systems.As for quality control devices,there were 1 792 dosimeters,2 143 ionization chambers,935 two-dimensional array dosimeters,540 threedimensional dosimetric verification systems,596 three-dimensional water tanks,844 anthropomorphic phantoms,and 1 168 water equivalent phantoms.In the aspect of therapeutic situation,there were 102,170 beds (including beds in departments of oncology in general hospitals),76612 episodes per day,and 919339 episodes per year.Conclusions The results of this investigation show significant increases in radiotherapy units,personnel,and equipment in recent years in mainland China.The distribution of radiotherapy units and equipment and the structure of radiotherapy personnel are becoming more reasonable,but there are still some problems.In some regions,current radiotherapy equipment cannot meet the medical needs,and there is a lack of professional technical personnel.%目的 为进一步了解当前中国大陆地区放疗基本情况,合理配置放疗人才及设备资源,有效促进中国放疗发展,中华医学会肿瘤放疗学分会进行了第7次调查.方法 2015年10月8日到2015年12月期间,专门成立放疗基本信息调查办公室,通过各省主委提供本省放疗单位、名单及联系方式,采用专用数据填报系统通过互联网完整、快速、高效的完成调查.结果 截至2016年1月20日(1)单位:1413家;(2)人员:52496人,其中放疗医师15 841人(高级职称4824人)、技师8454人(高级职称260人)、物理师3294人(高级职称562人)、维修师938人(高级职称120人);(3)放疗设备:直线加速器1 931台,60Co远距离治疗机96台,X刀171台,γ刀210台,近距离治疗机439台,X线模拟定位机1051台,CT 1 353台,MRI 642台,MLC 978套,TPS 1 922套,放疗网络974家;(4)质控设备:剂量仪1 729台,电离室2 143台,二维矩阵935台,三维剂量验证仪540台,三维水箱596台,仿真体摸844套,等效水体摸1 168套;(5)治疗情况:病床数102171张(含综合医院肿瘤科病床),每日治疗76612人次,每年治疗919339人次.结论 调查结果显示中国大陆地区近年来放疗单位、放疗人员和设备均呈明显增加,放疗单位及设备分布、放疗人员结构趋于合理,但局部地区仍存在放疗设备尚不能满足医疗需求、专业技术人员缺乏等现实问题.
