Postoperative adjuvant radiotherapy plays an important role in the treatment of patients with breast cancer. With the continuous development of radiotherapeutic technologies, the requirements for radiotherapeutic accuracy are increasingly high. The accuracy of target volume and organ at risk delineation significantly affects the effect of radiotherapy. Automatic delineation software has been continuously developed for the automatic delineation of target areas and organs at risk. Automatic segmentation based on an atlas and deep learning is a hot topic in current clinical research. Automatic delineation can not only reduce the workload and delineation times, but also establish a uniform delineation standard and reduce inter-observer and intra-observer differences. In patients with breast cancer, especially in patients who undergo left breast radiotherapy, the protection of the heart is particularly important. Treating the whole heart as an organ at risk cannot meet the clinical needs, and it is necessary to limit the dose to specific cardiac substructures. The present review discusses the importance of automatic delineation of target volume and cardiac substructure in radiotherapy for patients with breast cancer.
术后辅助放疗在乳腺癌患者的治疗中发挥着重要作用。随着放射治疗技术的不断发展，对放射治疗精度的要求越来越高。靶区体积和危及器官勾画的准确性显著影响放疗效果。自动勾画软件不断发展，用于自动勾画靶区和危及器官。基于图谱和深度学习的自动分割是当前临床研究的热点。自动勾画不仅可以减少工作量和勾画时间，还可以建立统一的勾画标准，减少观察者间和观察者内差异。在乳腺癌患者中，尤其是接受左乳放疗的患者，心脏保护尤为重要。将整个心脏作为危及器官进行处理不能满足临床需求，有必要将剂量限制在特定的心脏亚结构。本综述讨论了乳腺癌患者放疗中靶区体积和心脏亚结构自动勾画的重要性。
