Study Notes
AML Classification Overview
- Therapy-related Acute Myeloid Leukemia (AML) arises from previous treatments.
- Down Syndrome-related AML is specific to patients with Down Syndrome.
- Four significant chromosomal abnormalities in AML:
- t(8;21)
- t(15;17)
- t(4;11)
- inv(16)
- No minimum blast count is necessary for the above chromosomal abnormalities.
- AML with Myelodysplastic Syndrome (MDS) related changes indicates a history of dysplasia or MDS mutations.
- If AML does not fit major WHO categories, it is classified as AML Not Otherwise Specified (NOS) under FAB classification.
FAB Classification of AML
-
M0:
- AML without differentiation; hard to distinguish from Acute Lymphoblastic Leukemia (ALL).
- Markers: CD 13+, 33+, 117+ (c-kit); absence of lymphoid differentiation.
-
M1:
- Minimal differentiation with myeloperoxidase positivity (MPO+).
-
M2:
- Exhibits differentiation.
- Associated with translocation t(8;21) (AML1-ETO).
- Blasts show Auer rods and chloromas.
-
M3 (Acute Promyelocytic Leukemia - APML):
- Linked to t(15;17) PML-RARA translocation.
- Cells demonstrate basket appearance full of granules and rods.
-
M3v:
- Microgranular variant of M3 with no significant differences from M3.
-
M4:
- Acute myelomonocytic leukemia, characterized by at least 20% myeloblasts and common peripheral monocytosis.
-
M4eo:
- Acute myelomonocytic leukemia with eosinophilic precursors, identified by inv(16).
-
M5:
- Acute monocytic leukemia presents with gingival hyperplasia, chloroma involvement, and central nervous system (CNS) consequences.
-
Infant t(4;11):
- Typically categorized under M4 or M5 in the FAB system.
-
M6:
- Known as erythroblastic leukemia.
-
M7 (Acute Megakaryocytic Leukemia - AMKL):
- In Down syndrome patients, characterized by Gata-1 mutation.
- In non-Down syndrome patients, associated with translocation t(1;22).
