摘    要:目的前瞻性的比较超声内镜和螺旋CT检查对胃癌术前TNM分期的应用价值及探讨TNM分期标准的改变对两者准确性的影响。方法对43例经活检证实的胃癌患者术前分别行超声内镜和螺旋CT检查,确定肿瘤侵犯深度(T)、局部淋巴结转移(N)、周围及远处器官转移(M)等情况,并与术后病理检查结果对照。结果对T分期的准确率,内镜超声检查(EUS)为71.1%,螺旋CT检查(HCT)为65.8%,两者的准确率差异无统计学意义(P>0.05),对T1、T2期胃癌,EUS与HCT的准确率分别为71.4%、14.3%(P=0.05)。对N分期的准确率,以第四版TNM分期标准,EUS与HCT分别为76.3%和65.8%,以第五版TNM分期标准,EUS与HCT分别为60.5%和63.2%,两者的准确率差异均无统计学意义(P>0.05)。对M分期两者的准确率分别为30%(3/10)、80%(8/10),P<0.05.结论EUS和HCT在胃癌术前TNM分期中均有较高的准确性,对胃壁较浅层受浸润深度的判断以EUS为优,对远处转移的判断以HCT为优;TNM分期标准改变对两种方法的N分期结果均无明显影响。

Abstract:Objective: To compare endoscopic ultrasonography and helical computed tomography in the TNM staging of gastric cancer and to assess the impact of changes in the TNM classification on the staging accuracy of these methods. Methods: Both EUS and HCT were performed in 43 patients with gastric cancer proved by biopsy, and the results of EUS and HCT were compared prospectively with surgical pathological findings. Results: The T-staging accuracy of EUS (71.1%) was similar to the accuracy of HCT (65.8%).The accura...
