    High-risk acute promyelocytic leukemia (APL) has an early mortality rate of 15%–25%, necessitating effective induction therapies.

  • 2

    Reduced-intensity induction with ATRA+ATO achieves a complete remission rate of 92.3%, comparable to 89.3% with intensive chemotherapy.

  • 3

    Early mortality rates are similar between reduced-intensity (8.8%) and intensive (10.4%) therapies, indicating safety in reduced-intensity approaches.

  • 4

    Event-free survival is significantly better with reduced-intensity induction (HR = 0.23, p = 0.015), supporting its use as first-line therapy.

  • 5

    The study concludes that reduced-intensity ATRA+ATO with GO or low-dose anthracycline is preferred for high-risk APL treatment.
