摘要
目的探讨MSCT征象在预测肾透明细胞癌(CCRCC)Fuhrman分级中的应用。方法回顾性分析经病理及免疫组织化学确诊的肾透明细胞癌87例,将Ⅰ级与Ⅱ级共47例合并作为低级别组,Ⅲ级与Ⅳ级共40例合并作为高级别组。采用χ~2检验或Fisher确切概率法对低级别组与高级别组的CT征象,包括囊性肾癌、假包膜、肿瘤血管、肾周侵犯、淋巴结转移、肾静脉癌栓、钙化、坏死进行统计与分析。结果低级别组囊性肾癌的发生率高于高级别组,差异有统计学意义(P=0.000);高级别组肾周脂肪囊侵犯、肿瘤血管、淋巴结转移、肾静脉癌栓、钙化、坏死的发生率高于低级别组,差异有统计学意义(P=0.005、0.000、0.041、0.041、0.001、0.000)。结论 MSCT可用于初步预测肾透明细胞癌的Fuhrman分级。
Objective To explore MSCT features in predicting the Fuhrman grade of renal cell carcinoma（ CCRCC）.Methods A retrospective analysis of 87 cases with renal cell carcinoma confirmed by pathology and immunohistochemistry was done. We merged grade Ⅰ and grade Ⅱ comprising of 47 cases into the low grade group and grade Ⅲ and grade Ⅳ of 40 cases as the high grade group. The CT features including cystic renal cell carcinoma,pseudocapsule,tumor vessels,perirenal fat invasion,lymph node metastasis,renal vein tumor thrombus,calcification and necrosis were recorded and analyzed by χ^2 or Fisher＇s exact test. Results The incidence of cystic renal cell carcinoma in the low grade group was higher than that in the high grade group,the difference was statistically significant（ P = 0. 000）. The incidence of perirenal fat invasion,tumor vascularisation,lymph node metastasis,renal vein tumor thrombus,calcification and necrosis was higher than that in low grade group,the difference had statistical significance（ P = 0. 005,0. 000,0. 041,0. 041,0. 001,0. 000）.Conclusion MSCT can be used to predict the Fuhrman grade of CCRCC preliminarily.
