APML4 [60 years and under] - Induction (LEU APL - APML4 induction, consolidation 1 and 2 followed by maintenance [60 years and under])

Treatment Overview

Differentiation syndrome:

  • Monitor closely for differentiation syndrome in the first 7 to 10 days of treatment.
  • Prompt recognition and treatment with high dose intravenous corticosteroids is necessary until 3 days or longer after complete resolution of symptoms.
  • Decision to withhold tretinoin and arsenic trioxide should be only for severe cases or if lack of response to corticosteroid.

Cycle 1 - 36 days

Cycle length:
36

prEDNISone: Take until white cell count less than 1 x 109/L, or until resolution of differentiation syndrome.


tretinoin:

  • Consider dose reduction of tretinoin to 25 mg/m2 daily in TWO divided doses in patients under 20 years of age to reduce risk of pseudotumour cerebri.
  • Teratogenic—Ensure pregnant women are not exposed to tretinoin. Consult prescribing information.

arsenic trioxide:

  • May prolong QTc interval and close monitoring is recommended. Avoid or reduce risk factors for QTc prolongation.
  • Azole antifungals may increase QTc interval. Consult prescribing information.
