目的研究多层螺旋CT(MSCT)对直肠癌术前TNM分期的真实性、可靠性.方法对2009年1-12月山西省肿瘤医院收治的301例直肠癌患者的临床资料进行回顾分析,比较术前MSCT分期与术后病理分期,采用Medcalc软件对结果进行ROC曲线分析及诊断一致性分析.结果 TNM分期的灵敏度、特异度、Kappa值、曲线下面积分别是:T2期为64.7%、96.8%、0.667、0.808;T3期为93.8%、75.0%、0.709、0.844;T4期为87.8%、98.1%、0.859、0.929;N分期为72.0%、91.2%、0.619、0.816;M分期为92.7%、99.7%、0.925、0.963.结论 MSCT对直肠癌浸润程度和淋巴结转移的评价有明显的局限性,不宜单独用于直肠癌术前分期的评估.

Objective To evaluate the validity and reliability of multi-slice spiral CT (MSCT) in preoperative TNM staging judgment of rectal carcinoma. Methods Three hundred and one patients with rectal carcinoma were diagnosed and treated consecutively in Colorectal and Anal Surgery Department of Shanxi Province Tumor Hospital from January 2009 to December 2009. The clinical data of these patients were analyzed retrospectively. The diagnosis results were compared between the preoperative MSCT staging and the postoperative pathological staging,the ROC curve and the diagnostic concordance test were analyzed by software Medcalc 11.2. Results The sensitivity, specificity, Kappa value, area under the curve of TNM staging were 64.7% ,96. 8% ,0. 667,0. 808 for T2 staging tumors; 93.8% ,75.0% ,0.709,0.844 for T3 staging tumors;87. 8% ,98. 1% ,0. 859,0. 929 for T4 staging tumors; 72. 0% ,91.2% ,0. 619,0. 816 for N staging tumors;92. 7%, 99. 7%, 0. 925,0. 963 for M staging tumors respectively. Conclusion The diagnostic value of independent use of MSCT in estimating the infiltration degree and lymph node metastasis of rectal cancer is very poor and cannot be used in preoperative staging judgment.
