[Flow cytometric analysis of renal cell carcinoma].

Forty cases of renal cell carcinoma were studied retrospectively by flow cytometry and DNA contents of the cancer cells were measured. The results indicated that the incidence of aneuploid tumor was 57.5% (23/40), diploid tumor or quasi-diploid tumor 42.5% (17/40). DNA ploidy was strictly correlated to histopathological grade, clinical stage, cancer cell type and survival time. Therefore, analysis of cellular DNA ploidy of renal cell carcinoma is of prognostic value for renal cell carcinoma.
