Risk-stratified Therapy for Acute Myeloid Leukemia in Down Syndrome
This phase III trial studies response-based chemotherapy in treating newly diagnosed acute myeloid leukemia or myelodysplastic syndrome in younger patients with Down syndrome. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Response-based chemotherapy separates patients into different risk groups and treats them according to how they respond to the first course of treatment (Induction I). Response-based treatment may be effective in treating acute myeloid leukemia or myelodysplastic syndrome in younger patients with Down syndrome while reducing the side effects.
Phase: Phase III (Cancer Control)
Age Group: Children
Arm A: Standard risk
INDUCTION II: Patients receive cytarabine, daunorubicin, and thioguanine. Induction II continues for a minimum of 28 days.
INDUCTION III: Patients receive cytarabine, daunorubicin hydrochloride, and thioguanine as in Induction II. Induction III continues for a minimum of 28 days.
INTENSIFICATION I: Patients receive cytarabine and etoposide. Intensification I continues for a minimum of 28 days.
INTENSIFICATION II: Patients receive cytarabine and etoposide as in Intensification I. Intensification II continues for a minimum of 28 days.
Arm B: High risk
INDUCTION II: Patients receive high dose cytarabine and mitoxantrone. Induction II continues for a minimum of 28 days.
INTENSIFICATION I: Patients receive high dose cytarabine and etoposide. Intensification I continues for a minimum of 28 days.
INTENSIFICATION II: Patients receive high dose cytarabine. Patients also receive asparaginase or asparaginase Erwinia chrysanthemi. Intensification II continues for a minimum of 28 days.
