【摘要】：目的探讨多层螺旋(MS)CT三期增强扫描在胃癌术前TNM分期的应用价值。方法回顾性分析161例经手术和病理组织学证实的胃癌患者术前MSCT三期增强扫描的影像数据,由2名有经验的副主任/主任医师共同阅片后,根据肿瘤位置、胃壁浸润深度、淋巴结转移等情况对其进行TNM分期,并与术后病理组织学结果对照。结果与病理组织学TNM分期比较,MSCT术前TNM分期中T、N、M分期准确率分别为73.29%、77.02%、96.27%,T、N分期与病理组织学的一致性一般、较好(Kappa=0.715 4,0.724 1)。而M分期与病理组织学的一致性较好(Kappa=0.823 6)。结论胃癌MSCT三期增强扫描的CT征象与病理组织学具有较好的相关性,术前TNM分期的准确度较高,对临床手术和判断预后具有重要的指导意义。
[Abstract]:Objective to evaluate the value of multi-slice spiral CT three-phase enhanced MSCT in preoperative TNM staging of gastric cancer. Methods the imaging data of 161 patients with gastric cancer confirmed by operation and histopathology were retrospectively analyzed. TNM staging was performed according to the location of the tumor, the depth of gastric wall invasion and lymph node metastasis. Results compared with histopathologic TNM staging, the accuracy of TNM staging was 73.290.The accuracy of TNM staging was 77.02% and 96.27% respectively. The results showed that there was a good correlation between the CT signs and histopathology of gastric carcinoma by MSCT, and the accuracy of TNM staging before operation was higher than that of TNM staging before operation, but the consistency of M staging with histopathology was better than that of Kappa's stage 0.823 6. Conclusion the CT signs of three-phase MSCT enhanced scanning of gastric cancer have a good correlation with histopathology, and the accuracy of preoperative TNM staging is higher than that of preoperative TNM staging. It has important guiding significance for clinical operation and prognosis.
