摘要
淋巴结转移是影响食管癌患者预后的一个重要因素。为延长食管癌患者根治术后的生存时间，提高其生存质量，如何在精确放疗中既不漏失潜在的淋巴结转移范围，又不致使照射面积过大加重放疗反应成为大家研究的热点。本文从胸段食管癌淋巴结转移规律及分布特点，基于CT的放疗靶区勾画中对淋巴结定位的诊断价值及淋巴结对靶区勾画的影响等方面对该问题进行综述。
Lymph nodes metastasis is one of key factors affecting the prognosis of esophageal cancer patients. The research on neither omitting the potential lymph nodes metastasis nor increasing the radiation response for excessive exposure has become a hot spot in precise radiotherapy in order to improve the survival rate and life quality. This article reviewed the distribution of metastatic lymph nodes of thoracic esophageal carcinoma, the application of CT in diagnosis of lymph node metastasis and the influence of metastatic lymph nodes on radiotherapy target contour.
