Name

Acute myeloid leukemia with t(6;9)(p23;q34.1); DEK-NUP214

ICD-O-3 Morphology

9865/3: Acute myeloid leukemia with t(6;9)(p23;q34);DEK-NUP214
Effective 2010 and later

Reportable

for cases diagnosed 2010 and later

Primary Site(s)

C421
Primary site must be bone marrow (C421)

Abstractor Notes

(This code is effective for cases diagnosed 2010 and later. For cases diagnosed prior to 2010, see code 9861/3.)

This AML has a generally poor prognosis. Elevated white blood cell counts are most predictive of shorter overall survival and increased BM blasts are associated with shorter free survival. Very limited data available regarding treatment or survival.

In adults the WBC is generally lower than other AML types. The BM may have morphologic and cytochemical features of any FAB subtype of AML other than acute promyelocytic leukemia and acute megakaryoblastic leukemia.

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

Diagnostic Confirmation

This AML is part of the "AML with recurrent genetic abnormalities" group. Since this AML is diagnosed based on genetics, diagnostic confirmation will always be 3.

Definition

Acute myeloid leukemia with t(6;9)(p23;q34.1) resulting in DEK-NUP214 is an AML with greater than or equal to 20% peripheral blood or bone marrow blasts with or without monocytic features. It is often associated with basophilia and multilineage dysplasia.

Progression and Transformation

Elevated white blood cell counts associated with shorter overall survival
Increased bone marrow blasts associated shorter disease-free survival

Epidemiology and Mortality

Age: 13 years median age in children, 35 years median age in adults
Incidence: 0.7-1.8% of AML cases
Survival: poor prognosis for both children and adults
