Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - asparaginase
Treatment: Drugs - cytarabine
Treatment: Drugs - daunorubicin hydrochloride
Treatment: Drugs - methotrexate
Treatment: Drugs - therapeutic hydrocortisone
Treatment: Drugs - thioguanine

Experimental: Arm A: TMD patients only - Patients are observed if their transient myeloproliferative disorder (TMD) does not require intervention. Patients who require therapy for TMD undergo leukapheresis or exchange transfusion for up to 3 consecutive days. If the TMD does not resolve or there is significant organ involvement, patients receive low-dose cytarabine IV continuously on days 0-4. Treatment repeats at least every 2 weeks for up to 4 courses. Patients who experience a recurrence of TMD at least 8 weeks after resolution or have refractory disease may proceed to group II for further treatment. patients will continue to be followed for remission induction, EFS, DFS and OS regardless of the type of leukemia that develops.

Experimental: Arm B: AML/MDS patients only - (closed to accrual as of 6/24/04 except for patients first enrolled in group I): Patients receive induction therapy comprising cytarabine IV continuously, daunorubicin hydrochloride IV continuously, and oral thioguanine twice daily on days 0-3. Treatment repeats every 28 days for 4 courses. Patients with no CNS disease at diagnosis receive cytarabine intrathecally (IT) on day 0. Patients with CNS disease at diagnosis receive cytarabine IT on days 0, 5, and 7. If CNS disease persists on day 7, patients receive up to 6 courses of cytarabine IT, therapeutic hydrocortisone IT, and methotrexate IT, twice weekly beginning on day 10. Asparaginase during Intensification 1 day 1 hour 18.
