      | Abstract |  | Intrachromosomal amplification of chromosome 21 (iAMP21) defines a distinct cytogenetic subgroup of childhood B-cell precursor acute lymphoblastic leukemia. Breakage-fusion-bridge cycles followed by chromothripsis and other complex structural rearrangements of chromosome 21 underlie the mechanism giving rise to iAMP21. Patients with iAMP21 are older (median age 9 years), with a low white cell count. They have a high relapse rate when treated as standard risk. Recent studies have shown improved outcome on intensive therapy. Molecular targets for therapy are being sought. |
