目的:评价螺旋CT(SCT)在直肠癌术前分期中的价值。方法:对58例直肠癌患者术前行SCT检查,与手术及病理结果对比,观察SCT对直肠肿瘤浸润深度、区域淋巴结转移和远处转移判断的准确性。结果:SCT术前分期总的准确率为65.5%(38/58),T分期的准确率为81.0%(47/58),N分期的准确率为67.2%(39/58),评价肿瘤侵犯外膜的敏感性和特异性分别为97.9%(46/47)和63.6%(7/11),评价淋巴结转移的敏感性为71.1%(27/38),特异性为60.0%(16/20)。结论:SCT对直肠癌术前判断外膜侵犯、淋巴结转移和远处转移情况有重要价值。
Objective: To evaluate the value of spiral CT (SCT) in the preoperative staging of rectal cancer. Methods: Fifty-eight patients with rectal cancer underwent SCT preoperatively. The accuracy of SCT in determining the depth of invasion, regional lymph node metastasis and distant metastasis of the rectal cancer was observed in comparison with the surgical and pathological findings. Results: The overall accuracy of preoperative SCT was 65.5% (38/58), the accuracy of T staging was 81.0% (47/58), and the accuracy of N staging was 67.2% (39/58) The sensitivity and specificity of the adventitia were 97.9% (46/47) and 63.6% (7/11) respectively. The sensitivities of lymph node metastasis were 71.1% (27/38) and 60.0% (16/20) ). Conclusion: SCT plays an important role in preoperative diagnosis of adventitia, lymph node metastasis and distant metastasis.
