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:B-Lymphoblastic Leukemia/Lymphoma with Hyperdiploidy.

(General Instructions – The main focus of these pages is the clinically significant genetic alterations in each disease type. 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 to a table, click within the table and select the > symbol that appears to be given options. 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)

WHO Classification of Disease

Structure Disease
Book Haematolymphoid Tumours (5th ed.)
Category B-cell lymphoid proliferations and lymphomas
Family Precursor B-cell neoplasms
Type B-lymphoblastic leukaemias/lymphomas
Subtype(s) B-lymphoblastic leukaemia/lymphoma with high hyperdiploidy

Definition / Description of Disease

B-ALL with hyperdiploidy is a neoplasm of lymphoblasts committed to the B-cell lineage whose blasts contain >50 chromosome (usually <66), typically without translocations or other structural alterations.  


In the context of B-ALL, hyperdiploidy is further subdivided into two groups including low hyperdiploidy (47–50 chromosomes) and high hyperdiploidy ( > 50 chromosomes) with some studies further defining the high hyperdiploid subgroup as those with a modal chromosome number of 51–68. [1] [2] [3] [4]

Synonyms / Terminology

Put your text here (Instructions: Include currently used terms and major historical ones, adding “(historical)” after the latter.)

Epidemiology / Prevalence

The incidence of hyperdiploidy in B-ALL decreases with age: [5][6][7][8][9]

  • approximately 25% of pediatric patients (ages 1–9 years)
  • approximately 10% of adolescents (ages 10–15 years)
  • approximately 5–7% of adults (age > 19 years)

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 Features
The content below was from the old template. Please incorporate above.

The presenting features are generally similar to those seen in patients with other ALLs.

Sites of Involvement

Put your text here (Instruction: Indicate physical sites; EXAMPLE: nodal, extranodal, bone marrow)

Morphologic Features

Put your text here

Immunophenotype

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)
  • Pediatric patients with high hyperdiploidy have been reported to have a favorable prognosis with cure seen in >90% of children [10]
  • High event-free survival (EFS) was associated with trisomy 4, 6, 17, 18, and 22, presence of triple trisomies (4, 10, 17), and high modal numbers ( > 50 chromosomes) [11]
  • Negative prognostic features include > 10 years of age, male gender, and bone marrow fibrosis [12]
  • Patients with low hyperdiploidy have been reported to have a 49% EFS at 5 years compared to those with high hyperdiploidy with a five-year EFS of 71% [13]
  • Familial Forms

Hyperdiploidy is readily identifiable by conventional chromosome studies, FISH and CMA. CMA studies have shown that approximately 80% of hyperdiploid cases have additional genomic abnormalities with chromosomes commonly involved being 1, 9, 11, 12, and X.
