摘要
目的评价多层螺旋CT（MSCT）多期增强及三维后处理技术对肾细胞癌（RCC）手术前TNM分期诊断的准确性。方法搜集经病理确诊为肾细胞癌患者102例,逐一回顾性分析其影像学特点并进行肿瘤TNM分期,采用Kappa（κ）检验比较MSCT分期与术后病理分期的一致性。结果 MSCT对于RCC的原发肿瘤（T）分期对比术后病理结果具有极好的一致性（κ=0.872）,而在RCC的区域淋巴结（N）分期与病理对照中的一致性则一般（κ=0.583）。MSCT及后处理技术准确评价了所有（8例）合并有肾静脉瘤栓及（或）下腔静脉瘤栓。结论 MSCT多期增强及三维后处理对肾细胞癌T分期诊断具有较高的准确性,但对N分期准确性较差,并能显示肿瘤范围、静脉瘤栓、瘤体血供特点,可为RCC临床及手术决策提供参考依据。
Objective To evaluate the accuracy of multi-slice spiral CT （MSCT） muhi-phase enhancement and threedimensional post-processing in the diagnosis of TNM staging of renal cell carcinoma （RCC）. Methods A total of 102 patients with renal cell carcinoma diagnosed by pathology from November 2014 to October 2016 were analyzed retrospectively for their imaging characteristics and tumor TNM staging. The comparison of MSCT staging and postoperative pathological staging was evaluated using the Kappa （to） statistic. Results MSCT had excellent correlation （ K = 0.872） in the prima- ry tumor （T） staging of RCC compared with the postoperative pathological findings, while in the regional lymph node （N） staging of RCC was not consistent with the pathological control （ K = 0. 583 ）. MSCT and post-processing techniques accurately evaluated all （8） patients with renal vein thrombus and（or） tumor thrombus. Conclusion MSCT muhi-phase enhancement and three-dimensional post-processing have a high accuracy in the diagnosis of T-staging of renal cell carcinoma, but the accuracy of N staging is poor, and can show the tumor range, venous thrombus, and provide reference for RCC clinical and surgical decision-making.
