Abstractor Notes

Acute myeloid leukemia, NOS is a generic disease description. DCO cases or path report only cases may stay in this classification.

In most cases, NOS histology is only the provisional diagnosis; the physician will run further diagnostic procedures and look for various clinical presentations to identify a more specific disease. Further review of the medical record should be done to look for the tests listed as definitive diagnosis. If no information is found in the medical record, follow-back to the attending physician should be done.

More specific myeloid leukemias include
1. Acute myeloid leukemia (megakaryoblastic) with t(1;22)(p13.3;q13.1); RBM15-MKL1 (9911/3)
2. Acute myeloid leukemia with BCR-ABL1 (9912/3) (2021)+
3. Acute myeloid leukemia with biallelic mutation of CEBPA (9878/3) (2021+)
4. Acute myeloid leukemia with inv(3)(q21.3q26.2) or t(3;3)(q21.3;q26.2); GATA2, MECOM (9869/3)
5. Acute myeloid leukemia with inv(16)(p13.1q22) or t(16;16)(p13.1;q22); CBFB-MYH11 (9871/3)
6. Acute myeloid leukemia with maturation (9874/3)
7. Acute myeloid leukemia with minimal differentiation (9872/3)
8. Acute myeloid leukemia with mutated NPM1 (9877/3) (2021+)
9. Acute myeloid leukemia with mutated RUNX1 (9879/3) (2021+)
10. Acute myeloid leukemia with myelodysplasia-related changes (9895/3)
11. Acute myeloid leukemia with t(6;9)(p23;q34.1); DEK-NUP214 (9865/3)
12. Acute myeloid leukemia, t(8;21)(q22;q22.1); RUNX1-RUNX1T1 (9896/3)
13.Acute myeloid leukemia with t(9;11)(p21.3;q23.3); KMT2A-MLLT3 (9897/3)
14. Acute myeloid leukemia without maturation (9873/3)
15. Myeloid leukemia associated with Down syndrome (9898/3)
16. Myeloid/lymphoid neoplasms with PDGFRB rearrangement (9966/3)

When a more specific diagnosis is identified, the histology should be changed to the more specific neoplasm name and code. See the histology tables for more information on NOS and more specific histologies.

This histology should also be used when the diagnosis is "Acute myeloid leukemia with recurrent genetic abnormalities" and there are no specific recurrent genetic abnormalities listed.

Specific AML histologies with recurrent genetic abnormalities include:

9865: Acute myeloid leukemia with t(6;9)(p23;q34.1) DEK-NUP214
9866: Acute promyelocytic leukemia with PML-RARA
9869: Acute myeloid leukemia with inv(3)(q21.3q26.2) or t(3;3)(q21.3;q26.2); GATA2, MECOM
9871: Acute myeloid leukemia with inv(16)(p13.1q22) or t(16;16)(p13.1;q22); CBFB-MYH11
9877: Acute myeloid leukemia with mutated NPM1 (2021+)
9878: Acute myeloid leukemia with biallelic mutation of CEBPA (2021+)
9879: Acute myeloid leukemia with mutated RUNX1 (2021+)
9896: Acute myeloid leukemia with t(8;21)(q22;q22.1); RUNX1-RUNX1T1
9897: Acute myeloid leukemia with t(9;11)(p21.3;q23.3); KMT2A-MLLT3
9911: Acute myeloid leukemia (megakaryoblastic) with t(1;22)(p13.3;q13.1); RBM15-MKL1
9912: Acute myeloid leukemia with BCR-ABL1 (2021)+

If the leukemia occurs before or simultaneously with Myeloid Sarcoma (9930/3), see M3 and Module 5:PH10.

DCO cases or path report only cases may stay in this classification.

Diagnostic Confirmation

This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.

Definition

Acute myeloid leukemia (AML), NOS, encompasses the cases that do not fulfill the criteria for inclusion in one of the more specified AML entities. The defining criterion for AML is the presence of greater than or equal to 20% myeloid blasts in the peripheral blood or bone marrow.

Bone marrow biopsy
Genetic testing
Immunophenotyping

CD11b
CD13
CD14
