目的评估超声内镜(EUS)在残胃癌TNM分期中的准确性。方法北京大学临床肿瘤学院从2001年10月至2009年3月对连续的21例病理证实的残胃癌病人给予超声内镜检查,行TNM分期。所有病人行手术治疗,对照术后病理。结果评价超声内镜诊断结果结果经超声内镜检查,21例残胃癌中T2为3例,T3为9例,T4为9例;N0为3例,N1为6例,N2为4例,N3为10例,其中手术标本病理分期T2为3例T3为13例,T4为5例,N0为3例,N1为4例,N2为6例,N3为8例。超声内镜在残胃癌T,N分期中的诊断准确率分别为81.0%和76.2%。结论超声内镜是残胃癌临床分期的一种准确、无创的检测手段。因观察范围所限、淋巴结检测应结合CT等方法完善分期。
Objective To evaluate the accuracy of endoscopic ultrasonography (EUS) in TNM staging of gastric stump cancer. Methods From October 2001 to March 2009, Peking University School of Oncology and Oncology was followed up by endoscopic ultrasonography in 21 patients with pathologically confirmed residual gastric cancer. TNM staging was performed. Surgical treatment of all patients, control postoperative pathology. Results The results of endoscopic ultrasound diagnosis by endoscopic ultrasonography showed that in 21 gastric cancer cases, T2 was 3 cases, T3 was 9 cases, T4 was 9 cases, N0 was 3 cases, N1 was 6 cases, N2 was 4 cases, N3 There were 10 cases in which pathological stage T2 was performed in 3 cases, T3 was 13 cases, T4 was 5 cases, N0 was 3 cases, N1 was 4 cases, N2 was 6 cases and N3 was 8 cases. The diagnostic accuracy of endoscopic ultrasonography in staging T and N staging was 81.0% and 76.2% respectively. Conclusion Endoscopic ultrasonography is an accurate and non-invasive detection method for gastric staging of gastric cancer. Due to the limited scope of observation, lymph node detection should be combined with CT and other methods to improve staging.
