Abstract
Seven kidney tumors obtained from patients aged from 5 to 76 years were analyzed by flow cytometry for cell cycle, DNA content and P-glycoprotein expression involved in multidrug resistance. The DNA index seems to be an important criterion since all the tumors were aneuploid. In a case of clear cell carcinoma, two aneuploid clones were identified. In 5 cases of kidney tumors a high proportion of cells in proliferation (S + (G2 + M)) was observed; it was comprised between 13 and 33%. As for P-glycoprotein it was detected only in few tumor cells (5-15%) respectively in a case of clear cell carcinoma and in a case of Wilms' tumor.
