目的探讨肾透明细胞癌的CT表 现与Ki67、MVD、P73表达的相关性，通过 CT表现评价其部分生物学行为。方法 分 析经手术病理证实的30例肾透明细胞癌 的CT表现，同时对其进行相关免疫组化染 色，分析肾透明细胞癌的CT表现及其与 MVD、Ki67、P73表达的相关性。结果 肾 透明细胞癌中的囊变坏死、肿瘤边界、最 大强化程度及大小均与Ki67、MVD、P73 表达正相关(P<0.05)，肿瘤出血与MVD、 Ki67表达有统计学意义(P<0.05)，而与 P73表达无关(P>0.05)，钙化与Ki67、 MVD、P73表达无统计学差异(P>0.05)。结 论 1、通过MSCT扫描，可以对肾透明细胞 癌进行比较准确的术前诊断。2、肾透明 细胞癌的部分CT征象与Ki67、MVD、P73的 表达具有相关性，可能在一定程度反映出 肿瘤的生物学特性。

Objective To study the correlation between CT features and the expression of Ki67 and MVD, P73 in clear renal cell carcinoma (CCCRCC). So as to evaluate CT features of CCRCC and its biological behaviour. Methods To analyse the CT features of 30 cases with CCRCC which were confirmed by operation and pathology . The expression of MVD, Ki67, P73 of the collected organic material were confirmed by Immunohistochemical staining.then analized the relationship between CT features and the expression of MVD and Ki67, P73. Results 1,The expression of Ki67, MVD, P73 and MVD of CCRCC are positively related to the tumor boundary, the largest enhanced degree, the biggest tumors size (P<0.05). The positive expression of Ki67 and MVD are related to hemorrhage of the tumors (P<0.05), but has nothing to do with the expression of P73 (P>0.05).There is no statistical difference between calcification and the expression of Ki67, MVD, P73 (P>0.05). Conclusion 1, An accurate preoperative diagnosis of CCRCC can be made by MSCT scanning. 2, Some of CT features of CCRCC have correlation with the expression of Ki67, MVD and P73, it illustrate that CT manifestation of CCRCC may reflect the biological characteristic of the tumors partly.
