Clinical study of the color Doppler ultrasonic and TNM staging of renal cell carcinoma / 中国基层医药

ABSTRACT

Objective To explore clinical value of the color Doppler ultrasonic(CDU)and TNM staging of renal cell carcinoma.Methods 265 cases of renal cell carcinoma(RCC)confirmed by surgical pathology were retro-spectively analyzed.According to the WHO 2004 pathological types of classification standards and the American Joint Committee on Cancer(AJCC)cancer staging manual/6th TNMstaging criteria.The analyzed application of a CDFI to TNMstaging of renal cell carcinoma,and surgical pathology results werecompared.Results 265 cases of RCC and right kidney in 136 cases,129 cases of left kidney;Diameter of 1.5 -12.8cm;Pathological diagnosis of renal clear cell carcinoma in 226 cases(85.28%),28 cases of papillary renal cell carcinoma(10.57%),renal too color cell car-cinoma in 5 cases(1.89%),4 cases of multilocular cystic renal cell carcinoma(1.51%),Bellini duct carcinoma in 2 cases(0.75%).Diagnosis results of CDU and pathological in 250 cases(94.34%),CDU misdiagnosis leakage 15 cases(5.66%).Within the kidney showed low echo or high echo,and mixed echo lumps,and invasive growth to the surrounding tissues or organs sign for it.CDU showed the various blood flow signals were given priority to with renal clear cell carcinoma;CDU and surgical pathology TNMstaging coincidence rate was 90.40%(226 /250),inclu-ding T1 N0 -1 M0 ,T2 N0 -1 M0 ,T3 N0 -2 M0 -1 and T4 N0 -2 M0 -1 of coincidence rate were 92.12%(152 /165),85.71%(36 /42),82.14%(23 /28)and 100.00%(15 /15).Conclusion CDU can be used as the preferred method of diag-nosis and evaluation of renal cell carcinoma,which can can provide valuable information for TNMstaging.
