摘　　要：目的与术后病理对比,评估多层螺旋CT增强扫描用于胃癌术前TNM分期的价值。方法回顾性纳入219例经术后病理证实的胃癌患者,与术后病理对比,评估螺旋CT增强扫描术前判断TNM分期的效能。结果219例中,增强螺旋CT检出214例胃癌,检出率97.72%(214/219),漏诊率2.28%(5/219)。上述214例中,螺旋CT增强扫描判断胃癌T、N、M分期的准确率分别为91.12%(195/214)、88.79%(190/214)、85.98%(184/214),与术后病理具有较高至极高的一致性,Kappa值分别为0.868、0.844、0.701。结论多层螺旋CT增强扫描用于胃癌术前TNM分期具有较高价值。Objective To observe the value of multi-slice spiral CT enhanced scanning for preoperative TNM staging of gastric cancer compared with postoperative pathology.Methods A total of 219 patients with gastric cancer confirmed by postoperative pathological examination were retrospectively enrolled.The efficacy of spiral CT enhanced scanning for preoperative TNM staging,and its consistency with postoperative pathology were analyzed.Results Multi-slice spiral CT enhanced scanning detected gastric cancer in 214 cases,with detection rate of 97.72%(214/219)and missed diagnosis rate of 2.28%(5/219).Among these 214 cases,the accuracy of spiral enhanced CT for T,N,M staging of gastric cancer was 91.12%(195/214),88.79%(190/214)and 85.98%(184/214),respectively,which was high to extremely high consistent with that of postoperative pathology,with Kappa value of 0.868,0.844 and 0.701,respectively.Conclusion Multi-slice spiral CT enhanced scanning had high value for preoperative TNM staging of gastric cancer.
