摘要
目的探讨肾透明细胞癌(RCCC)的常规超声(CUS)、超声造影(CEUS)特征与病理分期及分级的相关性。方法回顾性分析83例经病理检查证实为RCCC的CUS及CEUS声像图特征,与TNM病理分期、Fuhrman病理分级结果进行比较,统计并分析相关性。结果不同TNM病理分期,CUS与CEUS在显示坏死率方面无统计学差异(P=0.220),但在假包膜及血供显示程度方面,有显著统计学差异(P<0.0001)。2种检查方法显示的坏死率与TNM病理分期均呈正相关(CUS:γ=0.328,P=0.002;CEUS:γ=0.276,P=0.007),而在假包膜及血供显示程度方面均无相关性。在病理分级Ⅱ级中,CEUS的假包膜及血供显示率明显高于CUS,并具有统计学差异(P=0.001,P=0.004)。以上CUS及CEUS特征与Fuhrman病理分级均无相关性。结论不同TNM病理分期RCCC,具有不同的CUS及CEUS特征。CEUS因具有更高的假包膜、血管以及坏死显示率,能为RCCC的诊断,尤其是早期RCCC的诊断提供更多诊断依据。
Objective To investigate the relationship between pathologic differentiation of renal cell clear cancer( RCCC) and characteristics of conventional ultrasound( CUS) and contrast-enhanced ultrasound( CUES). Methods A retrospective analysis of CUS and CEUS sonographic features of 83 patients with pathologically confirmed RCCC were conducted,and TNM staging,Fuhrman grade pathology results were compared and statistical correlations were analyzed. Results At TNM staging,CUS and CEUS in display necrosis rate had no significant difference( P = 0. 220),but in terms of fake blood capsule and show the extent of supply,there had statistically significant difference( P < 0. 0001). Necrosis rate and TNM staging showed that 2 methods had a positive correlation( CUS: γ = 0. 328,P = 0. 002; CEUS: γ = 0. 276,P = 0. 007),and in terms of fake blood capsule and display degree had no correlation. In pathological grade Ⅱ stage,CEUS fake blood capsule and display rate was significantly higher than that of CUS,and there had significant difference( P = 0. 001,P = 0. 004). CUS and CEUS characteristics and pathological Fuhrman grading had no correlation. Conclusion Different TNM staging of RCCC has different CUS and CEUS characteristics.CEUS has higher false capsule,blood vessels and necrosis display rate,it can diagnose RCCC,especially provide more diagnosis basis for the early diagnosis of RCCC.
