Haematolymphoid Tumours (WHO Classification, 5th ed.)

editContent Update To WHO 5th Edition Classification Is In Process; Content Below is Based on WHO 4th Edition Classification
This page was converted to the new template on 2023-12-07. The original page can be found at HAEM4:Enteropathy-Associated T-cell Lymphoma.

(General Instructions – The focus of these pages is the clinically significant genetic alterations in each disease type. This is based on up-to-date knowledge from multiple resources such as PubMed and the WHO classification books. The CCGA is meant to be a supplemental resource to the WHO classification books; the CCGA captures in a continually updated wiki-stye manner the current genetics/genomics knowledge of each disease, which evolves more rapidly than books can be revised and published. If the same disease is described in multiple WHO classification books, the genetics-related information for that disease will be consolidated into a single main page that has this template (other pages would only contain a link to this main page). Use HUGO-approved gene names and symbols (italicized when appropriate), HGVS-based nomenclature for variants, as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples); to add (or move) a row or column in a table, click nearby within the table and select the > symbol that appears. Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content. Please also see Author_Instructions and FAQs as well as contact your Associate Editor or Technical Support.)

EXAMPLE: ABL1 EXAMPLE: BCR::ABL1 EXAMPLE: The pathogenic derivative is the der(22) resulting in fusion of 5’ BCR and 3’ABL1. EXAMPLE: t(9;22)(q34;q11.2) EXAMPLE: Common (CML) EXAMPLE: D, P, T EXAMPLE: Yes (WHO, NCCN) 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). BCR::ABL1 is generally favorable in CML (add reference).

EXAMPLE: CIC EXAMPLE: CIC::DUX4 EXAMPLE: Typically, the last exon of CIC is fused to DUX4. The fusion breakpoint in CIC is usually intra-exonic and removes an inhibitory sequence, upregulating PEA3 genes downstream of CIC including ETV1, ETV4, and ETV5. EXAMPLE: t(4;19)(q25;q13) EXAMPLE: Common (CIC-rearranged sarcoma) EXAMPLE: D EXAMPLE:

DUX4 has many homologous genes; an alternate translocation in a minority of cases is t(10;19), but this is usually indistinguishable from t(4;19) by short-read sequencing (add references).

EXAMPLE: ALK EXAMPLE: ELM4::ALK


Other fusion partners include KIF5B, NPM1, STRN, TFG, TPM3, CLTC, KLC1

EXAMPLE: Fusions result in constitutive activation of the ALK tyrosine kinase. The most common ALK fusion is EML4::ALK, with breakpoints in intron 19 of ALK. At the transcript level, a variable (5’) partner gene is fused to 3’ ALK at exon 20. Rarely, ALK fusions contain exon 19 due to breakpoints in intron 18. EXAMPLE: N/A EXAMPLE: Rare (Lung adenocarcinoma) EXAMPLE: T EXAMPLE:

Both balanced and unbalanced forms are observed by FISH (add references).

EXAMPLE: ABL1 EXAMPLE: N/A EXAMPLE: Intragenic deletion of exons 2–7 in EGFR removes the ligand-binding domain, resulting in a constitutively active tyrosine kinase with downstream activation of multiple oncogenic pathways. EXAMPLE: N/A EXAMPLE: Recurrent (IDH-wildtype Glioblastoma) EXAMPLE: D, P, T

  • IL-15 deregulation and disruption of intestinal immune homeostasis[3][14][15][16]
  • Overexpression of genes involved in Interferon-γ signaling[3]
End of V4 Section

Genetic Diagnostic Testing Methods

  • No specific recurrent genetic abnormalities that are diagnostic for EATL[17][18]
  • Clonality can be confirmed by T-cell receptor gene rearrangement studies[17][18]
    • Intraepithelial lymphocytes in type 2 refractory celiac disease show similar gene rearrangement size as EATL[17][18]
  • Chromosomal microarrays may identify genetic abnormalities frequently associated with EATL[17][18]
  • Next generation sequencing may identify genetic abnormalities frequently associated with EATL[17][18]
  • Morphology and immunophenotyping
    • Cut-off value of 20% aberrant intraepithelial lymphocytes (cytoplasmic CD3+, surface CD3, CD7+, CD103+, CD8, CD4) to distinguish from refractory celiac disease[19]

Familial Forms

  • While there is a genetic predisposition of those with HLA-DQ2 or HLA-DQ8 to develop celiac disease and EATL is a complication of celiac disease, familial forms of EATL are not described.
    • HLA-DQ2 (HLA-DQA1*0501 and DQB1*02) homozygosity - increased (at least 5-fold) risk for RCD and EATL[20]
    • HLA-DQB1*02 genotype correlated with 5q gain [21]

Additional Information

This disease is defined/characterized as detailed below:

  • Enteropathy-associated T-cell lymphoma (EATL) is an aggressive intestinal T-cell lymphoma more common in patients with celiac disease, especially type II refractory celiac disease (RCDII).
  • Most of the EATL cases develop through an intermediate step of RCDII, however it can also arise de novo in patients with celiac disease.[22]
  • RCDII can be defined as failure to respond to a strict gluten-free diet for at least 12 months and is associated with clonal expansion of immunophenotypically an aberrant IELs [23][24].
  • Celiac disease may be diagnosed prior to EATL diagnosis in 20-73% of cases, or both entities may be diagnosed concomitantly in 10-58% of the cases[23]
  • Risk factors include homozygosity for HLA-DQ2 and advanced age[23]

The epidemiology/prevalence of this disease is detailed below:

  • 0.5-1 in 1 million general population (2-5% in patients with celiac disease, 60-80% in patients with refractory celiac disease type 2)[25][26][27][28][29]
  • EATL accounts for 3% of peripheral T-cell lymphomas and represents 66% of all primary intestinal T-cell lymphomas[23]
  • More common in regions with a high prevalence of CD, particularly Europe (0.05–0.14 cases per 100 000 population)[30][31][25] and the USA (0.016 cases per 100 000 population)
  • Extremely rare in Asia due to low population frequency of celiac HLA risk alleles[25][26][27]
  • > 60% of all cases in intestinal T- cell lymphomas[25][26][27]
  • M:F 1.04:1 to 2.8:1[25][26][27]
  • 6th-7th decade of life[25][26][27]
  • Mostly Caucasian (> 90%)[25][26][27]

The clinical features of this disease are detailed below:

Many of the below features are indistinguishable from the presentation of celiac disease, which may delay the diagnosis of EATL. Persistent symptoms following gluten-free diet is highly suggestive of EATL.[26]

  • CD can be diagnosed at the time of EATL diagnosis[23]
  • Patients with RCD can sometimes present with small-intestinal ulceration (ulcerative jejunitis)[32][33].

If there is no prior diagnosis of celiac disease and lymphoma is the initial presentation, the following findings can point towards celiac disease associated EATL:

  • Anti-tissue transglutaminase-2 antibodies or Anti-endomysial antibodies
  • Dermatitis herpetiformis

Signs and symptoms - Abdominal pain; Weight loss; Gluten-insensitive diarrhea/malabsorption; Bowel obstruction or perforation (50% cases)

Laboratory findings - Anemia; Hypoalbuminemia; Hemophagocytosis

The sites of involvement of this disease are detailed below:

  • Small intestine (predominantly jejunum and ileum > large intestine and stomach)[26]
  • Dissemination to extra gastrointestinal sites: mesenteric and abdominal lymph nodes > bone marrow, lung, liver or skin[27][34][35].
  • Metastases involve intra-abdominal node > bone marrow > lung > liver > skin[26]
  • CNS (rare)[26]

The morphologic features of this disease are detailed below:

  • Pleomorphic medium to large sized neoplastic lymphoid cells with immunoblastic or anaplastic morphology.[27][23]
  • Angulated vesicular nuclei, prominent nucleoli, and a pale-staining cytoplasm [https://doi.org/10.3390/diagnostics13162629]
  • Extensive inflammatory background of histiocytes, eosinophils, small lymphocytes, and plasma cells [23]
  • Adjacent mucosa often displays the histological features of active CD, including increased IEL infiltration, crypt hyperplasia, and villous atrophy [27][23] [https://doi.org/10.3390/diagnostics13162629]
  • Angioinvasion and angiodestruction are commonly seen [23]
  • Neighborhood mucosa characterized by villous atrophy and crypt hyperplasia (non-malignant areas of celiac disease)[27]
  • Round or angulated vesicular nuclei[27]
  • Prominent nucleoli[27]
  • Moderate-abundant pale cytoplasm[27]
  • Extensive admixture of inflammatory cells (eosinophils, histiocytes)[27]
  • Angiocentric and angioinvasive features with extensive necrosis[27]

The immunophenotype of this disease is detailed below:

  • Approximately 25% of EATLs (primarily de novo EATL) are CD8+, and rare cases express TCRγδ[35][36]
  • Ki-67 is very low and CD30 is negative in RCDII, their appearance is useful to monitor RCDII progression to EATL and to indicate the need for chemotherapeutic regimens targeting dividing cells, a therapeutic option that is inefficient and even dangerous in RCDII.[22]
  • The most common immunophenotypic profile in EATL is given below:

Positive (universal) - CD3, CD7

Positive (frequent) - CD30 (harbinger of transformation to EATL from RCD2), NKP46 (not seen in IEL of CD or RCD1), CD103, cytotoxic granule-associated markers (TIA1, granzyme B, perforin)

Negative (frequent) - CD4, CD8, CD5, CD56, TCR, EBER

KI67 – high

RCD Type 1 RCD Type 2 EATL
Histopathology Identical to uncomplicated CD Moderate/ severe villous atrophy with atypical IELs Infiltration of medium to large sized pleomorphic IELs
IEL Immunophenotype Like CD; sCD3+, CD8+

Immunophenotype of intraepithelial lymphocytes (IEL):[37][1]

  • Varies depending on background type 1 or type 2 refractory celiac disease (RCD).
    • Type 1 (RCD1):
      • Milder symptoms with high 5-year survival with low risk of EATL development
      • Flow cytometry: sCD3+, CD8+, CD5+
    • Type 2 (RCD2):
      • Severe symptoms with protein-losing enteropathy leads to malnourishment (BMI < 18); low 5-year survival with increased risk of EATL
      • Flow cytometry: sCD3_, CD8-, CD5-
      • IHC:
        • NKP46: significantly more positive in RCD2 IEL than normal IEL in CD and RCD1; not specific for RCD2 or EATL, can be seen in MEITL; not seen in indolent T-cell LPD of GI tract
        • CD30+ indicates progression to EATL
