目的 :探讨超声新指标彩色血流信号平均密度 (MCVD)和病理免疫组化指标微血管密度 (MVD)在评估肾细胞癌血供情况的临床应用价值。方法 :对 3 8例肾细胞癌患者术前行超声检查 ,计测 MCVD值 ;术后对肿瘤组织标本切片行 CD3 4免疫组织化学染色 ,计测MVD,并进行统计学对比分析。结果 :3 8例肾细胞癌的 MCVD与 MVD呈正相关 ,与临床分期 (Robson分期法 )无明显相关。结论 :MCVD较 MVD能更好地反映肾细胞癌血管生成状况 ,于术前较准确评价肾癌血供
Objective: To investigate the clinical value of new ultrasound color flow signal average density (MCVD) and pathological immunohistochemistry microvessel density (MVD) in assessing the blood supply of renal cell carcinoma. Methods: Thirty-eight patients with renal cell carcinoma underwent ultrasonography and MCVD before operation. CD3 4 immunohistochemical staining was performed on the sections of the tumor tissue after operation. The MVD was measured and compared statistically. Results: There was a positive correlation between MCVD and MVD in 38 cases of renal cell carcinoma and no significant correlation with clinical stage (Robson staging). Conclusion: MCVD can better reflect the angiogenesis of renal cell carcinoma than MVD. Accurately evaluate the blood supply of renal cell carcinoma before operation
