摘要
目的通过病理对照常规平扫联合增强CT扫描评价结直肠癌肿瘤一般情况与临床T、N分期诊断效能指标,明确全腹部增强CT扫描的临床应用价值。方法回顾性分析2015年5月至10月我院经CT确诊的49例结直肠癌患者的临床资料,临床检查未发现结直肠癌远处转移。通过平扫加增强CT扫描并进行多平面重组评价结直肠癌肿瘤的一般情况(肿瘤位置、肿瘤尺寸、肿瘤大体病理类型)和结直肠癌T、N分期;将影像学分期与病理分期进行对照,分别计算T、N分期灵敏度、特异度、准确率;计算评价T、N分期正确率,进行一致性检验,P<0.05为差异具有统计学意义。结果 CT检测肿瘤位置、大体病理类型与手术结果相比符合率为100%。CT测量肿瘤最大径与手术测量数据分别为(2.26±1.40)cm、(2.37±1.38)cm,数据呈高度相关(r=0.906,P=0.000)。影像学分期T分期正确率为65.3%,一致性较好(k=0.467,P=0.000)。影像学分期N分期正确率为63.3%,一致性较好(k=0.440,P=0.000)。结论增强CT扫描可以在结直肠癌术前评估中提供足够信息,具有重要临床应用价值。
Objective To evaluate the accuracy of enhanced CT scan in clinical staging of colorectal cance by detecting the general sit-uation and T and N staging through plain scan combined with enhanced CT scan.Methods Totally 49 cases of colorectal cancer patients were enrolled in this study from May 2015 to October 2015,and it showed no distant metastasis of colorectal cancer in clinical examination. Evaluated the general situation （location,size,and pathologic type）and T and N staging of colorectal cancer through plain scan and enhanced CT scan and multiplanar restructuring.Compared the imaging staging with pathological staging,and respectively calculated the sensitivity,spe-cific degree and accuracy of T and N staging.Evaluated the accuracy of T and N staging with the consistency test,and the differences were statistically significant with P 〈0.05.Results The location and pathological type of tumor detected by CT scan were compared with the re-sults of operation,and the coincidence rate was 100%.The maximum diameter of the tumor was （2.26 ±1.40）cm from CT image and （2.37 ±1.38）cm from operation measure,and the data were highly correlated （r =0.906,P =0.000）.The coincidence rate of T staging was 65.3%,and the consistency was good （k =0.467,P =0.000）.The coincidence rate of N staging was 63.3%,and the consistency was good （k =0.440,P =0.000）.Conclusion Enhanced CT scan can provide sufficient information for the preoperative evaluation of colorectal cancer,and it has important clinical application value.
