摘要：

目的 分析超声内镜对胃癌术前TN分期的准确性，探讨超声内镜在胃癌术前分期中的应用价值。方法 收集133例术前接受超声内镜检查并行临床分期胃癌患者的临床资料，将术前TN分期情况与手术病理分期结果进行比较。结果 超声内镜对胃癌术前T分期判断的总体准确率为81.20% ，其中T1和T4准确率较高，分别为91.67%和85.0%，而T2和T3的准确率较低，分别为74.29%和70.0%；在T分期中，存在着分期过深或过浅的现象，本组8例分期过深，17例分期过浅；超声内镜术前分期与术后病理分期结果呈高度一致性。N分期判断的总体准确率为78.95% ，对淋巴结阳性的判断正确率较低（6610%）。结论 超声内镜能较准确地判断胃癌TN分期, 可为治疗方案的合理制订提供依据。

Abstract:

Objective To analyze the correctness of endoscopic ultrasonography (EUS) for the preoperative TN staging of gastric cancer and to explore the application value of EUS for the preoperative staging of gastric cancer. Methods Clinical data of 133 patients with gastric cancer who underwent preoperative EUS examinations and clinical staging were collected. The results of preoperative TN staging were compared to the results of postoperative histopathological staging. Results The overall accuracy rate of preoperatively clinical staging of T subsets for gastric cancer by EUS was 81.20%. The accuracy rates of T1 and T4 stages were higher and were 91.67% and 85.0%, respectively. The accuracy rates of T2 and T3 stages were lower and were 74.29% and 70.0%, respectively. Overestimation and underestimation were found during T-staging. Among all patients, 8 patients were overestimated and 17 patients were underestimated. The results of preoperative staging by EUS were highly consistent with the results of postoperative histopathological staging. The overall accuracy rate of N subsets by EUS was 78.95%. The accuracy rate for identifying positive lymph nodes was relatively low (66.10%). Conclusion Endoscopic ultrasonography can correctly identify the TN staging of gastric cancer and provide evidences for properly treatment options.
