定量CT纹理分析评估肾透明细胞癌Fuhrman分级的价值

The value of Quantitative CT Texture Analysis in Evaluating Fuhrman Grade of Clear cell Renal Cell Carcinoma

目的探讨定量CT纹理评估肾透明细胞癌(clear cell renal cell carcinoma,ccRCC)核分级。方法78例ccRCC分为52例Fuhrman低级别和26例高级别组。结果不同Fuhrman分级的平均值、标准差和相关度有差别(P<0.05),相关度可鉴别ccRCC的Fuhrman高、低级别(P<0.05),CT纹理特征间存在相关性(P<0.05)。结论定量CT纹理对ccRCC Fuhrman分级有应用价值。

Objective To evaluate the feasibility of quantitative CT texture analysis in evaluating the nuclear grade of clear cell renal cell carcinoma(ccRCC).Methods The data of 78 patients with ccRCC confirmed by pathology were retrospectively analyzed.According to Fuhrman classification,there were 52 cases in the Fuhrman low-level group and 26 cases in the high-level group.Results The average,standard deviation and correlation of different Fuhrman classifications were different(P<0.05).Correlation could identify Fuhrman high and low levels of ccRCC(P<0.05),and there was a correlation between CT texture features(P<0.05).Conclusion There is a certain clinical value in evaluating Fuhrman grade of ccRCC with CT texture analysis.
