Name

Acute myeloid leukemia with CEBPA mutation (see 9861/3 prior to 2021) (ICD-O-4: 98780/3)

ICD-O-3 Morphology

9878/3: Acute myeloid leukemia with biallelic mutation of CEBPA
Effective 2001 and later

Reportable

for cases diagnosed 1978 and later

Primary Site(s)

C421
Primary site must be bone marrow (C421)

Coding Manual: Hematopoietic Coding Manual (PDF)

Abstractor Notes

(This code is effective for cases diagnosed 2021 and later. For cases diagnosed prior to 2021 see code: 9861/3.)

Acute myeloid leukemia with CEBPA mutation is part of the Acute myeloid leukemia (AML) lineage table in the WHO 5th edition of Hematolymphoid Tumors. (See Appendix B in the Hematopoietic Manual, Table B6)

Blood and bone marrow are always involved.

If this leukemia and myeloid sarcoma (9930/3) occur during the same clinical workup, this is one primary, the leukemia.

If the myeloid sarcoma occurs after the diagnosis of the leukemia, that is a manifestation of the leukemia and is the same primary.

See Multiple Primary Rule M3

Diagnostic Confirmation

This histology must be coded as diagnostic confirmation code 3 until the 2027 updates are implemented in your software. Once the software updates are implemented: Assign code 1 for histological confirmation WITH positive genetics

Module Rule

None

Alternate Names

Definition

Acute myeloid leukemia (AML) with CEBPA mutation is characterized by CEBPA mutation that should be biallelic (biCEBPA) or, if single, must be located in the bZIP region of the gene (smbZIP-CEBPA). (WHO 5th edition)
