BCR/ABL1–like acute lymphoblastic leukemia (ALL) accounts for 15% to 30% of B‐lineage ALL, with a peak of incidence occurring in adolescence.This subgroup of patients is characterized by a peculiar transcriptional profile that resembles that of true BCR/ABL1–positive cases, and have a heterogeneous genetic background and a poor outcome.

Imatinib, a potent inhibitor of the oncogenic tyrosine kinase BCR-ABL, has shown remarkable clinical activity in patients with chronic myelogenous leukaemia (CML). However, this drug does not completely eradicate BCR-ABL-expressing cells from the body, and resistance to imatinib emerges. Although BC …

BCR-ABL-Rearranged Acute Lymphoblastic Leukemia Introduction. B-cell acute lymphoblastic leukemia is an aggressive cancer that arises from progenitor B-cells. Nearly one third of adult cases and over one-half of cases in patients older than age 60 harbor the BCR-ABL fusion protein, which promotes leukemogenesis by augmenting cellular
mutations in the BCR-ABL1 kinase (BCR-ABL1mut) that hinder the tyrosine kinase inhibitor (TKI) from binding and result in further drive of the disease.

Bcr-abl fusion product is classically due to chromosomal translocation t(9;22)(q34;q11) in CML. With the advent of fluorescent in situ hybridization (FISH), bcr-abl translocation can be demonstrated in the tumor cells of GS. As far as we know, this is the first reported case of FISH bcr-abl positive GS without CML and AML. * Corresponding author.
