目的：探讨不同类型肾癌细胞ＤＮＡ含量变化与临床的关系。方法：筛选３２例肾细胞癌标本切片行Ｆｅｕｌｇｅｎ染色，ＣＭＩＡＳ图像分析系统分析。结果：ＤＮＡ指数均值以肉瘤样癌最大，透明细胞癌最小（Ｐ＜０．０５）。透明细胞癌与集合管癌、肉瘤样瘤；集合管与嫌色细胞癌间具有显著差异（Ｐ＜０．０５）。以５倍体和大于５倍体细胞百分率高低依次为肉瘤样癌、集合管癌、颗粒细胞癌、嫌色细胞癌和透明细胞癌。结论：细胞ＤＮＡ含量在不同类型肾癌之间有明确的相关性，且其与肿瘤的恶性程度和临床预后有关
Objective: To investigate the relationship between the changes of DNA content in different types of renal cancer cells and clinical manifestations. Methods: 32 cases of renal cell carcinoma were screened by Feulgen staining and analyzed by CMIAS image analysis system. Results: The mean value of DNA index was the largest in sarcomatoid carcinoma and the smallest in clear cell carcinoma (P <0.05). Clear cell carcinoma and tubal cancer, sarcomatoid tumor; collection tube and chromophobe carcinoma were significantly different (P <0.05). To 5 times the body and greater than 5 times the percentage of somatic cells were sarcomatoid carcinoma, collecting ductal carcinoma, granulosa cell carcinoma, chromophobe and clear cell carcinoma. Conclusion: There is a clear correlation between cell DNA content and different types of renal cell carcinoma, and it is related to the degree of malignancy and clinical prognosis
