The delineation of organs at risk is the basis of radiotherapy oncologists' work. Indeed, the knowledge of this delineation enables to better identify the target volumes and to optimize dose distribution, involving the prognosis of the patients but also their future. The learning of this delineation must continue throughout the clinician's career. Some contour changes have appeared with better imaging, some volumes are now required due to development of knowledge of side effects. In addition, the increasing survival time of patients requires to be more systematic and precise in the delineations, both to avoid complications until now exceptional but also because re-irradiations are becoming more and more frequent. We present the update of the recommendations of the French Society for Radiation Oncology (SFRO) on new findings or adaptations to volumes at risk.
勾画危及器官是放射肿瘤学家工作的基础。实际上，这种勾画有助于更好地确定靶区，优化剂量分布，从而影响患者的预后，甚至他们的未来。这种勾画的学习必须贯穿整个临床医生的职业生涯。随着更好的成像技术的出现，一些轮廓发生了变化，由于对副作用的认识不断发展，现在需要一些新的体积。此外，由于患者的生存时间不断延长，在勾画时需要更加系统和精确，既要避免迄今为止罕见的并发症，也要考虑到再放疗越来越频繁的情况。我们介绍了法国放射肿瘤学会 (SFRO) 对新发现或风险器官体积的适应性调整的建议的更新。
