The success of radiotherapy depends on the accurate delineation of the clinical target volume. The delineation of the lymph node regions has most impact, especially for tumors in the head and neck region. The purpose of this article was the development an atlas for the delineation of the clinical target volume for patients, who should receive radiotherapy for a tumor of the head and neck region. Literature was reviewed for localisations of the adjacent lymph node regions and their lymph drain in dependence of the tumor entity. On this basis the lymph node regions were contoured on transversal CT slices. The probability for involvement was reviewed and a recommendation for the delineation of the CTV was generated.
放射治疗的成功取决于临床靶区的准确勾画。淋巴结区域的勾画影响最大,特别是对于头颈部肿瘤。本文的目的是为需要接受头颈部肿瘤放射治疗的患者开发一个临床靶区勾画图谱。通过复习文献,确定了邻近淋巴结区域及其与肿瘤实体的淋巴引流之间的位置关系。在此基础上,在横断 CT 切片上对淋巴结区域进行了描绘。回顾了受累的可能性,并提出了 CTV 勾画的建议。
