分组方法对超声造影诊断肾透明细胞癌假包膜显示率的影响

Influence on detecting pseudocapsule sign with methods of grouping in clear cell renal carcinoma

目的:本研究旨在探讨分组方法的不同对超声造影(CEUS)诊断肾透明细胞癌(CCRCC)假包膜显示率的影响。方法:回顾性分析经手术病理证实为CCRCC的83例患者(共87个肿瘤)的CEUS声像图特征,按不同分组标准进行分组。分别计算并比较不同分组方法中假包膜显示率,分析分组方法不同是否影响假包膜显示率。结果:7种不同分组方法中,第3种、第5种及第6种分组方法各组间假包膜显示率有显著差异,余分组标准中各组假包膜显示率无差异。结论:分组方法不同,CEUS对CCRCC假包膜显示率不同,分组方法影响CCRCC中CEUS假包膜显示率。

Objective： To evaluate the influence with different methods of grouping on detecting pseudocapsule sign of clear cell renal carcinoma （CCRCC） diagnosed by CEUS. Methods： The features of CEUS of 87 CCRCCs in 83 patients confirmed by pathology were retrospectively analyzed. Samples were divided into different groups by different methods of grouping criteria. The frequency of pseudocapsule sign of CCRCCs diagnosed by CEUS was calculated and compared in different meth- ods of grouping to analyse their influence on detecting pseudocapsule sign. Results： Among all the seven methods of grouping, there was statistically significant difference between the third, fifth and sixth grouping methods for detecting pseudocapsule sign of CCRCCs diagnosed by CEUS. No differences were found in the other grouping methods. Conclusion： Detection of pseudo- capsule sign of CCRCCs diagnosed by CEUS will be different according to different methods of grouping. The methods of grouping can affect the detection of pseudocapsule sign of CCRCCs diagnosed by CEUS.
