B-cell precursor t(8;14)(q11;q32)-positive acute lymphoblastic leukemia in children is strongly associated with Down syndrome or with a concomitant Philadelphia chromosome.
(2009) In European Journal of Haematology 82(1). p.46-53- Abstract
- We review the clinical and cytogenetic features of 44 acute lymphoblastic leukemias (ALLs) with t(8;14)(q11;q32), including three from our department and 41 ascertained in the literature, focusing on age and gender distribution, peripheral blood values, immunophenotypic data, survival and additional chromosomal changes. Most patients are children or young adults, with a median age of 10 yr for children and 28 for adults. There is a male preponderance, particularly in patients with Down syndrome (DS) or in children with concomitant t(9;22)(q34;q11). The median blood values are hemoglobin 72 g/L, platelets 17 x 10(9)/L and white blood cell count 9 x 10(9)/L, with hyperleukocytosis >50 x 10(9)/L having been reported in only approximately... (More)

There is a male preponderance, particularly in patients with Down syndrome (DS) or in children with concomitant t(9;22)(q34;q11). The median blood values are hemoglobin 72 g/L, platelets 17 x 10(9)/L and white blood cell count 9 x 10(9)/L, with hyperleukocytosis >50 x 10(9)/L having been reported in only approximately 10%. All reported cases have had a B-cell precursor immunophenotype, typically characterized by CD10+, CD19+, CD20+/-, CD22+, CD24+, CD34+, CD45dim/-, CD66c+/- and CD123+. At the time of reporting, 75% of the patients have been alive. The t(8;14) is the sole acquired change in 30%. The most common additional aberrations are t(9;22)(q34;q11), der(14)t(8;14), +21, +X and +14, the presence of which does not seem to confer a prognostic impact. A substantial proportion of the patients have DS (27%) or t(9;22) (16%). All patients with both t(8;14) and t(9;22) have been children without DS; the frequency of t(9;22) in that cohort is 30%. As t(9;22), or its molecular genetic correlate, may escape detection by conventional banding analysis we would strongly suggest that this aberration is actively looked for in pediatric ALL with t(8;14).
