摘要
目的探讨多层螺旋CT扫描在结肠癌术前分期中的应用。方法随机选取2020年1月—2023年10月济宁市第三人民医院收治的80例结肠癌患者为研究对象,均予多层螺旋CT检查,以手术病理结果为依据,评估CT对结肠癌术前TNM分期的诊断准确率及与病理结果的一致性。结果在结肠癌术前分期诊断中,多层螺旋CT对T1、T2、T3、T4期诊断符合率80.00%、91.67%、100.00%、93.33%,T分期准确率93.75%;对N0、N1、N2期诊断符合率88.00%、85.29%、95.24%,N分期准确率88.75%;对M分期诊断准确率91.25%;对TNM分期诊断结果与手术病理结果一致性较好(kappa=0.91、0.83、0.81)。结论结肠癌患者术前予多层螺旋CT检查TNM分期诊断准确率高,且与手术病理结果一致性较好。
Objective To investigate the application of multilayer spiral CT scanning in preoperative stag⁃ing of colorectal cancer.Methods A total of 80 patients with colon cancer admitted to the Third People's Hospi⁃tal of Jining from January 2020 to October 2023 were randomly selected as the research objects.All patients were examined by multilayer spiral CT.Based on the surgical pathological results,the diagnostic accuracy of CT for preoperative TNM staging of colon cancer and the consistency with pathological results were evaluated.Results In the diagnosis of preoperative staging of colorectal cancer,multilayer spiral CT had a diagnostic con⁃cordance rate of 80.00%,91.67%,100.00%,and 93.33%for T1,T2,T3,and T4 stages,and an accuracy rate of 93.75%for T staging.The diagnostic compliance rate for N0,N1,and N2 stages was 88.00%,85.29%,and 95.24%,and the N staging accuracy rate was 88.75%.The diagnostic accuracy rate for M staging was 91.25%;the diagnostic results for TNM staging were in good agreement with the surgical pathology results(kappa=0.91,0.83,0.81).Conclusion The diagnostic accuracy of TNM staging of colorectal cancer by multilayer spiral CT be⁃fore surgery is high,and the consistency with the gold standard is good.
