Phase I and pharmacokinetic evaluation of all-trans-retinoic acid in pediatric patients with cancer.

Abstract

The MTD and recommended phase II dose for RA in children is 60 mg/m2/d given twice daily. Reversible CNS toxicity related to RA-induced pseudotumor cerebri is dose-limiting. Two children with APL achieved a CR to RA, which supports the inclusion of pediatric patients in clinical trials that evaluate the use of RA for patients with APL.
