肾癌患者CT影像分型的临床研究

CT imaging in patients with renal cell carcinoma clinical study of type

目的：探讨肾癌患者的CT影像分型方法及其临床应用。方法：回顾性分析本院2009年4月-2011年2月经病理证实的肾癌患者78例，观察患者的CT影像分型及病理结果。结果：本组病例的CT影像可以分为4型，其中包括：经典型39例（50．0％），血管瘤样型20例（25．6％），弥漫型12例（15．4％），囊肿型7例（9．0％）。同时，本组病例中经CT影像分型诊断为：透明细胞癌65例（83.3％），嫌色细胞癌6例（7．7％），乳头状癌5例（6．4％），集合管癌2例（2．6％）。CT扫描增强后，肿瘤边界清楚64例（82．1％），边界不清14例（17．9％）。结论：通过CT影像分型可以准确区分肾癌患者的各具特征性及表现，但是难以准确反映出其病理分型结果。

Objective： To evaluate the CT imaging in patients with renal cell carcinoma and its clinical application type. Methods： A retrospective analysis of our hospital in April 2009 -2011 2 years in patients with pathologically confirmed renal cell carcinoma and 78 cases observed in patients with CT image classification and pathological findings. Results： The patients in the CT images can be divided into 4 types, including： the classic type in 39 cases （50.0%）, vascular tumor-like type in 20 cases （25.6%）, diffuse type in 12 cases （15.4%）, cysts in 7 cases （9.0%）. At the same time, this group of cases diagnosed by CT imaging classification as follows： 65 cases of clear cell carcinoma （83.3%）, chromophobe cell carcinoma in 6 cases （7.7%）, papillary carcinoma in 5 cases （6.4%）, collecting duct carcinoma in 2 cases （2.6%）. Enhanced CT scan, the tumor with clear boundary 64 patients （82.1%）, ill 14 cases （17.9%）. Conclusion： CT imaging can accurately distinguish the type of patients with kidney cancer each with characteristic and performance, but difficult to accurately reflect the results of its pathological type.
