64排螺旋CT在结肠癌分期诊断中的价值研究

Study on values of 64-slice spiral CT in the staging diagnosis of colon cancer

目的:探讨64排螺旋CT在结肠癌分期诊断中的价值研究。方法:2014年2月至2017年2月收治90例经纤维肠镜检查诊断为结肠癌患者,均进行64排螺旋CT扫描,将CT扫描分期诊断结果与手术病理结果进行比较分析。结果:(1)90例结肠癌患者CT-T分期诊断准确度为91.11%(82/90),T1~2期准确度为77.78%,T3期准确度为90.00%,T4期准确度为93.44%。(2)CT-N分期诊断准确度为88.89%(80/90),N0期准确度为91.49%,N1期准确度为86.96%,N2~3期准确度为85.00%。(3)CT-M分期诊断准确度为95.56%(86/90),M0期准确度为100%,M1期准确度为94.37%,有4例误诊为肝囊肿,手术后随访确诊为肝脏转移。结论:64排螺旋CT在结肠癌分期诊断中具有较好的临床价值。

Objective： To explore the values of 64-slice spiral CT in the staging diagnosis of colon cancer. Methods： 90 patients diagnosed with colon cancer by fiberoptic colonoscopy from February 2014 to February 2017 were selected and were given 64-slice spiral CT,and the results of CT scan staging diagnosis and surgical pathology were compared and analyzed. Results： The diagnostic accuracy of CT-T staging in 90 patients with colon cancer was 91. 11%（82/90）,and the accuracies of T1 ~ 2 phase,T3 phase and T4 phase were 77. 78%,90. 00% and 93. 44% respectively. The diagnostic accuracy of CT-N staging was 88. 89%（80/90）,and the accuracies of N0 phase,N1 phase and N2 ~ 3 phase were 91. 49%,86. 96% and 85. 00% respectively. The diagnostic accuracy of CT-M staging was 95. 56%（86/90）,and the accuracies of M0 phase and M1 phase were 100% and 94. 37% respectively,and 4 cases were misdiagnosed as hepatic cysts and were confirmed as liver metastases at follow-up after surgery. Conclusions： 64-slice spiral CT has good clinical values in the staging diagnosis of colon cancer.
