APL stands for Acute promyelocytic leukemia, a hematology and oncology abbreviation.

Subtype of acute myeloid leukemia caused by the t(15;17) translocation that creates the PML-RARA fusion gene. It often presents with life-threatening bleeding from disseminated intravascular coagulation and is a medical emergency.

Example: Pancytopenia, DIC and promyelocytes with Auer rods: suspected APL, ATRA started before genetic confirmation.

Usage notes

Once among the deadliest leukemias, APL is now among the most curable: all-trans retinoic acid combined with arsenic trioxide cures more than 90 percent of standard-risk patients without conventional chemotherapy, as shown in a 2013 Italian-German trial. Treatment starts on suspicion because early bleeding deaths are the main threat. Differentiation syndrome, with fever, fluid retention and breathing difficulty, is a recognized complication.
