WHO Classification of Disease
| Structure | Disease |
|---|---|
| Book | Haematolymphoid Tumours (5th ed.) |
| Category | Myeloid proliferations and neoplasms |
| Family | Acute myeloid leukaemia |
| Type | Acute myeloid leukaemia with defining genetic abnormalities |
| Subtype(s) | Acute myeloid leukaemia with DEK::NUP214 fusion |
Definition / Description of Disease
This is a distinct entity in the World Health Organization (WHO) classification system, and the most common associated French-American-British (FAB) classifications are M2, M4 and M1[1][2].
Synonyms / Terminology
None
Epidemiology / Prevalence
Accounts for 0.7-1.8% of AML, occurring in both children (median age of 13 years) and adults (median age of 35-44 years)[1].
Clinical Features
Put your text here and fill in the table (Instruction: Can include references in the table. Do not delete table.)
| Signs and Symptoms | EXAMPLE: Asymptomatic (incidental finding on complete blood counts)
EXAMPLE: B-symptoms (weight loss, fever, night sweats) EXAMPLE: Fatigue EXAMPLE: Lymphadenopathy (uncommon) |
| Laboratory Findings | EXAMPLE: Cytopenias
EXAMPLE: Lymphocytosis (low level) |
editv4:Clinical FeaturesThe content below was from the old template. Please incorporate above.Usually presents with anemia and thrombocytopenia and often with pancytopenia. In adults, the median white blood cell count is 12x10^9/L, which is generally lower than other AML types[1].
Sites of Involvement
Bone marrow
Morphologic Features
This AML subtype may present with or without monocytic features and is frequently associated with basophilia (44-62% of cases) and multilineage dysplasia (most commonly granulocytic and erythroid, and less often megakaryocytic dysplasia)[1]. Auer rods occur in ~1/3 of cases and ringed sideroblasts may also occur[1]. The peripheral blood or bone marrow have >20% blasts characterized by a non-specific myeloid immunophenotype[1].
Immunophenotype
The characteristic immunophenotype of the blasts associated with this entity is listed in the table below. In addition, basophils may present as separate clusters of CD123+, CD33+ CD38+ and HLA-DR- cells[1].
| Finding | Marker |
|---|---|
| Positive (universal) | Myeloperoxidase (MPO), CD9, CD13, CD33, CD38 CD123, and HLA-DR |
| Positive (subset) | KIT(CD117), CD34, CD15, CD64 (monocyte-associated marker), and Dexoynucleotidyl Transferase (TdT) |
| Negative (universal) | |
| Negative (subset) |
Chromosomal Rearrangements (Gene Fusions)
Put your text here and fill in the table
| Chromosomal Rearrangement | Genes in Fusion (5’ or 3’ Segments) | Pathogenic Derivative | Prevalence | Diagnostic Significance (Yes, No or Unknown) | Prognostic Significance (Yes, No or Unknown) | Therapeutic Significance (Yes, No or Unknown) | Notes |
|---|---|---|---|---|---|---|---|
| EXAMPLE: t(9;22)(q34;q11.2) | EXAMPLE: 3'ABL1 / 5'BCR | EXAMPLE: der(22) | EXAMPLE: 20% (COSMIC)
EXAMPLE: 30% (add reference) |
Yes | No | Yes | EXAMPLE:
The t(9;22) is diagnostic of CML in the appropriate morphology and clinical context (add reference). This fusion is responsive to targeted therapy such as Imatinib (Gleevec) (add reference). |
editv4:Chromosomal Rearrangements (Gene Fusions)The content below was from the old template. Please incorporate above.This AML subtype is classified based on the presence of a t(6;9)(p23;q34.1), which results in fusion of the 5’ portion of DEK at “6p23” (specifically 6p22.3[hg38]) and the 3’ portion of NUP214(CAN) at “9q34.1” (specifically 9q34.13[hg38]). The breakpoints are intronic, producing an in-frame fusion[3]. The DEK-NUP214 fusion present on the derivative chromosome 6 is considered the pathogenic entity as the reciprocal NUP214-DEK fusion on chromosome 9 does not appear to be transcribed[4]. Typically the DEK-NUP214 fusion presents as the sole abnormality but can be part of a complex karyotype[1].
Chromosomal Rearrangement Genes in Fusion (5’ or 3’ Segments) Pathogenic Derivative Prevalence t(6;9)(p23;q34.1) 5'DEK / 3'NUP214(CAN) der(6) 0.7-1.8% of AML
editv4:Clinical Significance (Diagnosis, Prognosis and Therapeutic Implications).Please incorporate this section into the relevant tables found in:
- Chromosomal Rearrangements (Gene Fusions)
- Individual Region Genomic Gain/Loss/LOH
- Characteristic Chromosomal Patterns
- Gene Mutations (SNV/INDEL)
This translocation has traditionally been associated with a poor prognosis in both adult and pediatric cases[1]. Of note, a 2014 retrospective analysis suggests a better outcome for pediatric patients with this translocation than previously reported[5]. Elevated white blood cell counts and higher bone marrow blast percentages are associated with shorter periods of overall survival and disease-free survival, respectively[1].
Limited data suggests early allogeneic stem cell transplantation may be associated with better overall survival compared to patients without transplantation, suggesting accurate diagnosis for these patients is crucial[1][6][7].
The concurrent presence of FLT3-ITD does not appear to negatively impact survival in the pediatric population[1].
Cases with the 6;9 translocation and <20% blasts are not currently classified as AML, which is controversial. Such cases should have close follow-up to monitor for development of more definitive evidence of AML or may be treated as AML if clinically appropriate[1].
