术前增强CT评估中老年胃癌分期的价值

The value of preoperative enhanced-CT in evaluating the staging of middle-aged and elderly patients with gastric cancer

目的:探究术前增强CT评估中老年胃癌分期的价值。方法:选取2014年1月—2020年12月在曙光医院经手术证实的138例中老年胃癌病例,均行增强CT检查,与术后病理对照,分析术前CT与手术病理T、N分期的一致性;结果:增强CT-T分期(T0、T1、T2、T3)的诊断准确性分别为50.0%、82.0%、91.3%、77.4%,CT-T分期与病理诊断一致性Kappa值为0.826(χ^(2)=272.359,P<0.001);增强CT-N分期(N0、N1、N2、N3)的诊断准确性分别为77.8%、90.6%、71.1%、53.3%,增强CT-N分期与病理诊断一致性Kappa值为0.738(χ^(2)=248.426,P<0.001)。结论:中老年胃癌术前增强CT分期与病理结果具有良好的一致性,可应用于临床。

Objective To explore the value of preoperative enhanced-CT in evaluating the staging of middle-aged and elderly patients with gastric cancer.Methods 138 cases of middle-aged and elderly patients with gastric cancer confirmed by surgical pathology in Shuguang Hospital from January 2014 to December 2020 were selected.All patients received enhanced-CT examination.The consistency of preoperative enhanced-CT diagnosis results with T and N staging confirmed by surgical pathology was analyzed using postoperative pathological results as the gold standard.Results The diagnostic accuracy of T stage(T0,T1,T2,T3)in the patients with gastric cancer was 50.0%,82.0%,91.3%,77.4%,respectively.The Kappa value of CT-T stage and postoperative pathological diagnosis was 0.826(χ^(2)=272.359,P<0.001);The accuracy of enhanced-CT in the diagnosis of N staging(N0,N1,N2,N3)was 77.8%,90.6%,71.1%,53.3%,respectively.The Kappa value of CT-N stage and postoperative pathological diagnosis was 0.738(χ^(2)=248.426,P<0.001).Conclusion Preoperative enhanced-CT is in good agreement with the staging results confirmed by surgical pathology,and can be used in the clinical staging diagnosis of middle-aged and elderly patients with gastric cancer.
