目的探讨超声内镜(EUS)检查在食管癌术前临床分期中的应用价值。方法回顾性分析35例确诊食管癌患者术前超声内镜(EUS)检查结果与术后病理检查。结果按2003年修改的国际抗癌联盟(UICC)和美国肿瘤联合会(AJCC)联合制定的TNM分期法分期。结果 EUS对食管癌的TN分期,T分期判断准确率为80%(28/35),对T1、T2、T3、T4诊断准确率分别为100%、90%、78.6%、50%;N分期准确率为80%,对N0、N1诊断准确率分别为73.3%、85%。结论 EUS对食管癌术前T、N分期诊断准确率较高,准确鉴别T2、T3及转移性淋巴结和炎性淋巴结是提高EUS准确率的重点和难点。
Objective To investigate the value of endoscopic ultrasonography (EUS) in preoperative clinical staging of esophageal cancer. Methods Retrospective analysis of 35 cases of diagnosed esophageal cancer patients with preoperative ultrasound endoscopy (EUS) examination results and postoperative pathological examination. The results were staged using the TNM staging method jointly developed by the International Union Against Cancer (UICC) and the American Cancer Society (AJCC) in 2003. Results The accuracy of T stage and ES stage of EUS was 80% (28/35), and the diagnostic accuracy of T1, T2, T3 and T4 was 100%, 90%, 78.6% and 50% The accuracy was 80%, and the diagnostic accuracy of N0 and N1 were 73.3% and 85% respectively. Conclusion EUS has a high diagnostic accuracy for preoperative T and N stages of esophageal cancer. Accurately identifying T2, T3, metastatic lymph nodes and inflammatory lymph nodes is the key and difficult point to improve the accuracy of EUS.
