Significance of thymidylate synthase activity in renal cell carcinoma.

Abstract

The present study is the first study to demonstrate that the level of TS activity was correlated with both the progression of the stage and the increase of the grade of RCC, and that higher TS activity in primary cultured RCC predicted higher sensitivity to 5-FU. These results suggest that high TS activity may be associated with malignant potential of RCC, and that it may be possible to use 5-FU for RCC with high TS activity.
