【摘要】目的:回顾分析食管癌食管气管沟淋巴结转移的CT表现及其与放疗预后的关系.方法:对2004年至2008年有完整临床和CT资料并有病理证实且放疗前均无远处转移,放疗后随访2年以上的食管癌食管气管沟淋巴结病例152例,分析其CT表现和预后情况,Kaplan-Meier法生存分析.152例均接受放射治疗,采用60Co、X射线照射,DT 50-70Gy,25-35次,35-49天,少数合并化疗.结果:各段食管癌均可发生食管气管沟淋巴结转移,CT是确诊的可靠方法.食管气管淋巴结转移右侧较左侧多.2年局部控制率轻度、中度强化相似(69.2％,57.1％,P＞0.05),密度均匀型好于小低密度和边缘强化内部坏死型(72.9％,54.0％,31.3％,P＜0.05,P＜0.05),边缘规则者好于边缘不规则和明显外侵者(73.9％,37.2％,33.3％,P＜0.05,P＜0.05).结论:食管癌食管气管沟淋巴结转移、转移淋巴结强化程度高、密度不均匀、边缘不规则或外侵的局部控制率明显下降,据此可以粗略判断预后.%Objective: To investigate the characteristics and prognostic value of computed tomography (CT) of tra-cheoesophageal groove lymph node (TGLN) in esophageal carcinoma. Methods: From 2004 to 2008, we analyzed CT images of 152 patients with histologically proven TGLN treated with radiation therapy in our hospital. The survival rate was evaluated by Kaplan - Meier method. All patients were treated with radiotherapy. The majority of patients were
