摘要
目的分析CT动态增强联合三维重建在结肠癌术前分期评估中的应用价值。方法回顾性分析2018年9月至2021年9月郑州市第九人民医院收治的105例结肠癌患者的临床资料,均行外科手术治疗,且术前进行CT常规平扫、CT动态增强检查联合三维重建处理,评估患者术前临床T分期情况;术后均进行病理检查,以病理检查结果为"金标准",分析CT动态增强联合三维重建在结肠癌患者术前分期评估中的应用价值。结果经术后病理证实,105例结肠癌患者中T0期0例,T1期21例,T2期34例,T3期37例,T4期13例;经Kappa一致性检验,CT常规平扫术前评估结肠癌患者T分期与术后病理结果一致性较为理想(Kappa=0.735,P<0.001),CT动态增强联合三维重建术前评估结肠癌患者T分期与术后病理结果的一致性极好(Kappa=0.947,P<0.001);以术后病理分期结果为"金标准",CT动态增强联合三维重建评估结肠癌患者术前T分期的准确率(96.19%,101/105)高于CT常规平扫(80.95%,85/105),P<0.05。结论CT动态增强联合三维重建术前评估结肠癌患者T分期较为准确。
Objective To analyze the value of dynamic enhanced computed tomography(CT)combined with three-dimensional reconstruction in evaluating preoperative staging of colon cancer.Methods Clinical data of 105 patients with colon cancer treated in Zhengzhou Ninth People’s Hospital from September 2018 to September 2021 were retrospectively analyzed.All patients underwent surgical treatment,moreover,routine CT plain scan,dynamic enhanced CT and three-dimensional reconstruction were performed before operation to evaluate the preoperative clinical T staging of the patients.Pathological examination was performed on patients after operation.Taking the pathological staging results as the gold standard,the value of dynamic enhanced CT combined with three-dimensional reconstruction in evaluating the preoperative staging of colon cancer was analyzed.Results Among the 105 patients with colon cancer,there were 0 cases in T0 stage,21 cases in T1 stage,34 cases in T2 stage,37 cases in T3 stage and 13 cases in T4 stage confirmed by postoperative pathology.According to Kappa test,the results of routine plain CT scan had great consistency with postoperative pathological staging in the evaluation of preoperative T staging of colon cancer(Kappa=0.735,P<0.001),while dynamic enhanced CT combined with three-dimensional reconstruction had good consistency with postoperative pathological examination in the evaluation of preoperative T stage of colon cancer(Kappa=0.947,P<0.001).Taking the results of postoperative pathological staging as the gold standard,the accuracy of dynamic enhanced CT combined with three-dimensional reconstruction in evaluating the preoperative T staging of colon cancer was 96.19%(101/105),which was higher than 80.95%(85/105)of conventional CT plain scan(P<0.05).Conclusions Dynamic enhanced CT combined with three-dimensional reconstruction is more accurate in evaluating the preoperative T staging of colon cancer.
