Abstract

The interindividual variation in the activity of xenobiotic metabolizing enzymes and DNA repair genes could modify an individual's risk of recurrent malignancy and response to therapy. We investigated whether ALL outcome was related to polymorphisms in genes CYP2D6. MPO, EPHX1, NQO1, TS, XPD and XRCC1 in 95 consecutive ALL children by PCR or PCR-FRLP techniques. Polymorphisms in genes NQO1 and TS were associated with a significantly slow response to induction chemotherapy and NQO1 was also associated with a lower five-year event-free survival. This study suggests that polymorphisms of NQO1 and TS could be important for patient response to induction therapy and for treatment outcome. (C) 2009 Elsevier Ltd. All rights reserved. (AU)
