B-Lymphoblastic Leukemia/Lymphoma with 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]

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

Characteristic Chromosomal Aberrations / Patterns
- Numerical increase in chromosomes usually without structural abnormalities
- Extra copies of chromosomes are non-random.
Genomic Gain/Loss/LOH
- Gains of chromosomes X, 4, 6, 10, 14, 17, 18 and 21 are most common with the following frequencies:
- 21 (98%)
- X (90%)
- 6 (83%)
- 14 (83%)
- 18 (78%)
- 4 (77%)
- 17 (73%)
- 10 (71%)
- 8 (38%)

Diagnostic Testing Methods
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.
Clinical Significance (Diagnosis, Prognosis and Therapeutic Implications)
- Pediatric patients with high hyperdiploidy have been reported to have a favorable prognosis with cure seen in >90% of children [17]
- 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) [18]
- Negative prognostic features include > 10 years of age, male gender, and bone marrow fibrosis [19]
- 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% [20]
