摘　　要：目的研究国际抗癌联盟（UICC）第7版分期标准下超声内镜（EUS）检查用于胃癌术前TNM分期评估的准确性。方法回顾性分析74例行胃癌根治性切除联合D2淋巴结清扫患者的临床资料,将术前EUS检查对肿瘤侵犯深度（T）、淋巴结转移（N）的评估结果与术后病理诊断结果进行比较。结果①EUS对肿瘤T分期评估准确率为86.4%。在T1期78.6%（11/14）,T2-3期83.3%（10/12）,T4期89.6%（43/48）。②EUS对肿瘤N分期评估准确率为70.3%。在N0期77.4%（24/29）,N1期60%（9/15）,N2期56.2%（9/16）,N3期（10/14）。结论 EUS检查在UICC第7版分期标准下借鉴该研究拟定的判定标准,对胃癌术前的TNM分期评估具有较高的价值,如何在新版标准下进一步提高评估的准确率尚需探讨。【Objective】To investigate the application of the endoscopic ultrasound（EUS） examination in the preoperative staging of gastric cancer under 7th edition UICC standard. 【Methods】We retrospectively analyzed clinical data from 74 gastric cancer patients undergoing gastrectomy with D2 lymph-node in People＇s Hospital of Tongling City Gastrointestinal Surgery Department and compared the results of preoperative EUS examination and postoperative pathological findings.【Results】① The overall accuracy of EUS of T staging was 86.4%. The accuracy of EUS in T1, T2-3 and T4 was 78.6%（11/14）,（10/12;83.3%）, T4（43/48;89.6%）, respectively. ② The overall accuracy of EUS of N staging was about 70.3%. The accuracy of EUS in N0, N1, N2, and N3 was 77.4%（24/29）, 60%（9/15）, 56.2%（9/16）, and 71.4%（10/14）, respectively.【Conclusion】The endoscopic ultrasound for TNM staging of gastric cancer is of greater clinical value under the new standard.
