Abstract [en]

We studied the pharmacokinetics of doxorubicin in 41 children treated for newly diagnosed acute myeloid leukemia. Doxorubicin, 75 mg/m body surface area, was administered by constant i.v. infusion over 8 h. Four children with Down's syndrome (DS), 1.2-2.3 years old, had a median total body clearance of 523 ml/min/m. The median clearance in non-DS children, 0.6-1.8 years old (n=4) and 2.5-17.7 years old (n=33), was 446 and 538 ml/min/m, respectively. Patients who went into complete remission (CR) after induction therapy had a significantly higher median plasma concentration of doxorubicin than those who did not, 249 compared with 180 ng/ml, respectively (P=0.036, analysis restricted to non-DS patients). Doxorubicin plasma concentration was an independent factor for CR, both in univariate (P=0.031) and multivariate analysis including sex, age and white blood cell count at diagnosis (P=0.021). Patients who reached CR had a significantly lower doxorubicin clearance than those who did not, 513 and 657 ml/min/m, respectively (P=0.017). In conclusion, doxorubicin plasma concentration and total body clearance during up-front treatment were correlated to the effect of induction therapy. Prospective studies should be performed to confirm the concentration-effect relationship and explore the possibility of therapeutic monitoring. © 2006 Lippincott Williams & Wilkins.
