摘要
目的探究胸部多排螺旋CT联合超声内镜检查在胸段食管癌术前分期的准确性。方法选取我院90例食管癌患者,患者术前均进行超声内镜检查、胸部多排螺旋检查,并对食管癌进行分期,术后患者肿瘤组织病理学分期为诊断的金标准,比较单用超声内镜、单用胸部多排螺旋及二者联合应用三种检查方法T与N分期的准确性。结果二者联合应用在T1、T2分期准确性高于MDCT,但与EUS差异小,T3、T4分期准确性及总准确性要高于单用EUS及单用MDCT;二者联合应用在N分期上敏感性、特异性,准确性及ROC曲线面积均高于单用EUS、单用MDCT,单用EUS敏感性为68.5%、特异性为70.6%、准确性为68.9%,ROC曲线面积为0.901;单用MDCT敏感性为63.0%、特异性为64.7%、准确性为63.3%,ROC曲线面积为0.853;二者联合应用敏感性86.3%、特异性82.4%、准确性为85.6%,ROC曲线面积为0.952。结论胸部多排螺旋CT联合超声内镜检查可以显著提高胸段食管癌术前T、N分期的准确性。
Objective To assess the combined application of endoscopic ultrasound and multi-detector row spiral CT in preoperative staging of esophageal cancer.Methods Choose 90 esophageal carcinoma patients who had been checked with endoscopic ultrasound and multi-detector row spiral CT. and do staging of esophageal cancer. Choose the pathological staging of the patient postoperative tumor tissue as the gold standard. Compare the T and N stages of the single use of endoscopic ultrasound and multi-detector row spiral CT, the combination of the two application.Results The combined application in T1, T2 staging accuracy is higher than MDCT, but the difference compared with EUS is less, The combined application in T3, T4 staging accuracy and total accuracy is higher than the single use of EUS and MDCT; The combined application in the N staging of sensitivity, specificity, accuracy and the area under ROC curve were higher than single use of EUS, MDCT. The sensitivity,specificity , accuracy and the area under ROC curve of the single use of endoscopic ultrasound and multi-detector row spiral CT, the combination of the two applications were 68.5%, 70.6%,80.90%, 0.901; 63.0%, 63.3%, 0.853; 86.3%, 82.4%, 85.6%, 0.952.Conclusion Thoracic multi-detector row spiral CT combined with endoscopic ultrasonography can improve the accuracy of thoracic esophageal carcinoma preoperative T, N staging significantly.
