Abstract:
Objective:To investigate the correlation between enhanced CT features and clinicopathological features of renal clear cell carcinoma.Methods:The clinicopathological data of 33 patients with renal clear cell carcinoma after radical operation in the Third People′s Hospital of Huzhou from January 2015 to January 2019 were analyzed retrospectively.The relationship between enhanced CT signs and pathological features was analyzed by speraman correlation analysis.Results:The pathological findings showed that there were 17 cases of capsule invasion and 16 cases of no capsule invasion, and there were statistically significant differences in lesion diameter, CT enhancement difference and enhancement rate between the two groups[(7.74±1.85)cm vs.(4.15±1.41)cm, (30.19±10.00)HU vs.(48.25±24.12)HU, (70.7±22.6)% vs.(137.0±86.6)%, t=-6.239, 2.841, 3.050, P=0.000, 0.008, 0.005]. There were statistically significant differences in lesion diameter and enhancement rate between patients with vascular tumor thrombus (12 cases) and without vascular tumor thrombus(21 cases)[(7.86±2.35)cm vs.(4.93±1.79)cm, (70.0±19.9)% vs.(121.0±81.7)%, t=-4.025, 2.074, P=0.000, 0.046], but there was no statistically significant difference in CT enhancement difference[(30.78±11.71)HU vs.(43.62±22.63)HU, t=1.823, P=0.078]. Spearman correlation analysis showed that there was a moderate negative correlation between CT enhancement difference and capsule invasion and vascular carcinoma thrombus( r=-0.593, -0.540, P=0.000, 0.001). The diameter of the lesion was positively correlated with capsule invasion( r=0.781, P=0.000). Conclusion:The diameter, CT enhancement difference and enhancement rate of renal clear cell carcinoma are different.The larger the diameter of the lesion and the smaller the enhancement difference indicate the capsule invasion and vascular carcinoma thrombus.
