摘　　要：目的探讨肺腺癌术前胸部CT影像与术后病理诊断纵隔淋巴结转移的一致性,为放疗靶区勾画提供依据。方法收集2009年1月至2011年11月107例肺腺癌患者的病历资料,将CT检出淋巴结与手术病理阳性淋巴结的大小和数量进行分析,计算淋巴结阳性转移率。结果 CT检出长径<15mm的淋巴结,其阳性转移率为26.8%;CT检出长径≥15mm的淋巴结,其转移率为72.6%。随着CT检出淋巴结数量增加,淋巴结长径增大,淋巴结阳性转移率升高。结论随着淋巴结长径的增大,淋巴结转移率逐渐升高;CT检出淋巴结>2个较≤2个转移率高,且长径较小时转移率就较高。Objective To investigate the diagnostic consistency of chest CT pre-operation and pathology post-operation of mediastinal lymph node metastasis in lung adenocarcinoma,in order to offer the basis for delineating target area.Methods From Jan.2009 to Nov.2011,107 patients of lung adenocarcinoma were enrolled in this study.The size and number of mediastinal lymph nodes scanned by chest CT and diagnosed by pathology were analyzed,and the rate of metastasis was calculated.Results The metastasis rate of length ＜ 15mm detected by chest CT was 26.8％,and the rate of length ≥ 15mm detected by chest CT was 72.6％.With the increasing of lymph node number detected by CT and lymph node diameter,the metastasis rate raised.Conclusion With the increase of lymph node length,the metastasis rate is increasing gradually.The metastasis rate is higher in lymph nodes ＞ 2 than in ≤2,even in smaller length of lymph node.
