What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

• Dexamethasone continuousDrug

  6 mg/m2, per os, in two divided doses per day q12 hours. 1-28 day (dose in the first few days is depending on the total tumor mass). From day 29 the dose of dexamethasone is reducing: days 29-31 - 3 mg/m2, days 32-34 - 1.5 mg/m2, days 35-36 - 0.75 mg/m2; then dexamethasone is discontinued completely.

• Dexamethasone intermittentDrug

  6 mg/m2, per os, in two divided doses per day q12 hours. Days: 1-14 (dose in the first few days is depending on the total tumor mass) and 22-28; days 15-21 - pause. From day 29 the dose of dexamethasone is reducing: days 29-30 - 3 mg/m2, days 31-32 - 1.5 mg/m2, then dexamethasone is discontinued completely.

• DexamethasoneDrug

  Induction: 6 mg/m2, per os, in two divided doses per day q12 hours. 1-28 day (dose in the first few days is depending on the total tumor mass). From day 29 the dose of dexamethasone is reducing: days 29-31 - 3 mg/m2, days 32-34 - 1.5 mg/m2, days 35-36 - 0.75 mg/m2; then dexamethasone is discontinued completely.

  Consolidation: 6 mg/m2 per os, in two divided doses per day q12 hours. Weeks 13-14 (days 85-98), weeks 21-22 (days 141-154), weeks 29-30 (days 197-210), weeks 37-38 (days 253-260), weeks 45-46 (days 309-316), weeks 53-54 (days 365-372).

  Maintenance therapy: 6 mg/m2, per os, in two divided doses per day q12 hours, for 10 days followed by quick discontinuation during 3 days. Weeks 61-62, 69-70, 77-78, 85-86, 93-94.

• MethylprednisoloneDrug

  Induction: 60 mg/m2, per os, in two divided doses per day q12 hours. 1-28 day (dose in the first few days is depending on the total tumor mass). From day 29 the dose of dexamethasone is reducing: days 29-31 - 30 mg/m2, days 32-34 - 15 mg/m2, days 35-36 - 8 mg/m2; then methylprednisolone is discontinued completely.

  Consolidation: 60 mg/m2 per os, in two divided doses per day q12 hours. Weeks 13-14 (days 85-98), weeks 21-22 (days 141-154), weeks 29-30 (days 197-210), weeks 37-38 (days 253-260), weeks 45-46 (days 309-316), weeks 53-54 (days 365-372).

  Maintenance therapy: 60 mg/m2, per os, in two divided doses per day q12 hours, for 10 days followed by quick discontinuation during 3 days. Weeks 61-62, 69-70, 77-78, 85-86, 93-94.

• DaunorubicinDrug

  Induction: 45 mg/m2, intravenously, for 6 hours on days 8 and 22. Consolidation: 30 mg/m2, intravenously, for 6 hours on days 44, 65 (consolidation S1); 107, 121 (consolidation S2); and 163 (consolidation S3).

• IdarubicinDrug

• Second phase of inductionDrug

  Cyclophosphamide (1,000 mg/m2, intravenously, for 1 hour - days 43 and 71); Cytarabine (75 mg/m2/day, intravenously, bolus injection. Four blocks of 4 days each, days 46-48, 52-55, 59-62, and 66-69); 6-mercaptopurine (60 mg/m2/day, per os, days 43-71); Triple intrathecal therapy (days 52 and 66)

• Standard induction therapyDrug
