目的:基于AAPM TG-263实现宫颈癌放疗危及器官(OAR)和靶区命名标准化。方法:采用Matlab软件自编程实现放疗结构文件的读取与解析后，逐一自动输出、记录、存储每个子结构命名。对所有子结构命名统计整理后，以关键词对结构名进行归类。根据TG-263制定OAR和靶区标准命名转换表，并通过程序对归类后的结构名进行标准化处理。最后，输出标准化命名后的放疗结构文件，并导入计划系统。结果:144例宫颈癌患者的放疗结构均成功转化，并在放疗计划系统中正确显示。转化前OAR和靶区的命名缺乏统一的规范与标准，同一结构的命名存在较大的差异；转化后将43种OAR、74种靶区的命名方式分别规范统一成20种与8种，方便工作人员的理解与沟通。结论:实现宫颈癌放疗结构命名标准化，可减少命名的不一致性，并为盆腔肿瘤命名标准化提供参考。“,”Objective:To standardize the naming of organ at risk (OAR) and target area during cervical cancer radiotherapy based on AAPM TG-263.Methods:After self-programming of Matlab software to implement the reading and resolution of radiotherapy structure files, the naming of each substructure was automatically output, recorded and restored. After naming all substructures, the structure names were classified by keywords. According to TG-263, a standard naming conversion table of OAR and target area was developed, and the classified structure names were standardized through procedures. Finally, the standardized named radiotherapy structure files were output and imported into the treatment planning system (TPS).Results:The radiation structure of 144 patients with cervical cancer was successfully transformed and displayed correctly in TPS. Before the transformation, the naming of OAR and target area lacked of uniform norms and standards, and the naming of the same structure significantly differed. After the transformation, 43 naming methods of OAR and 74 naming methods of the target area were unified into 20 and 8 naming methods, which were more convenient for staff understanding and communication.Conclusion:The standardization of cervical cancer radiotherapy structure naming can reduce the inconsistency of naming and provide reference for the standardized naming of pelvic tumors.
