目的探讨常规二维超声联合超声造影在鉴别肾细胞癌(RCC)亚型中的应用价值。方法 104例RCC患者中,透明细胞癌(CCRCC)69例,乳头状细胞癌(PRCC)11例,嫌色细胞癌(ChRCC)24例。将常规二维超声和超声造影声像图与术后病理结果进行对照分析。结果 CCRCC病灶出现血流分布64例,多于PRCC和ChRCC的4例和15例(χ2=24.52,P<0.01)。CCRCC表现“快进快出”和“同进同出”及高增强模式的例数均多于PRCC和ChRCC(P<0.01)。常规二维超声和超声造影在鉴别CCRCC和非CCRCC的敏感性分别为92.75%和75.36%,特异性分别为45.71%和65.71%。结论常规超声联合超声造影鉴别RCC亚型上有一定的诊断价值。
Objective To investigate the value of routine two-dimensional ultrasound combined with contrast-enhanced ultrasound in the differential diagnosis of renal cell carcinoma (RCC) subtypes. Methods Sixty - four patients with RCC were divided into two groups: 69 cases of clear cell carcinoma (CCRCC), 11 cases of papillary carcinoma (PRCC) and 24 cases of chromophobe carcinoma (ChRCC). The conventional two-dimensional ultrasound and contrast-enhanced ultrasound and pathological results were compared. Results The distribution of blood flow in CCRCC was 64 cases, more than 4 cases and 15 cases of PRCC and ChRCC (χ2 = 24.52, P <0.01). There were more cases of CCRCC than PRCC and ChRCC (P <0.01). The sensitivity of conventional two-dimensional ultrasound and contrast-enhanced ultrasound in the differential diagnosis of CCRCC and non-CCRCC were 92.75% and 75.36% respectively, and the specificity was 45.71% and 65.71% respectively. Conclusion Conventional ultrasound combined with contrast-enhanced ultrasound in the diagnosis of RCC subtypes have some diagnostic value.
