More frequently than is assumed, BCR-ABL1 -positive ALL resembles a chronic myeloid leukemia–like disease in lymphoid blast crisis. 14 Therefore, novel therapeutic strategies should target CD19 – malignant precursor cells in addition to the B-cell leukemic bulk, especially in patients with the MPP pattern.

2020-04-13 · For example, while phase 2 evaluation of ponatinib showed impressive responses in highly refractory patients with a variety of BCR-ABL1 point mutations, among patients who discontinued therapy ∼25% had evidence of a BCR-ABL1 compound mutation, more commonly in CML blast crisis and Ph+ ALL patients than those with chronic-phase disease (Cortes et al., 2013, Deininger et al., 2016). Monitoring BCR-ABL1 transcript levels in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) is a widely adopted method to assess response to therapy. However, a small minority of Ph+ ALL patients express variant BCR-ABL1 transcript types, usually due to splicing of alternative BCR or ABL1 exons.

The most frequent copy number aberration in BCR/ABL1–like ALL is IKZF1 deletion, which is documented in approximately 27% of pediatric cases and in approximately 70% of high‐risk pediatric patients with ALL. 16 IKZF1 deletions initially were recognized as a negative prognostic marker both in patients with BCR/ABL1–positive and those with BCR/ABL1‐negative ALL. 7, 45-49

A BCR-ABL test is most often used to diagnose or rule out chronic myeloid leukemia (CML) or a specific form of acute lymphoblastic leukemia (ALL) called Ph-positive ALL. Ph-positive means a Philadelphia chromosome was found. The test is not used to diagnose other types of leukemia. The test may also be used to: TriCore Reference Laboratories now offers a screening assay and diagnostic algorithm for the identification of BCR-ABL1-like B-lymphoblastic leukemia/lymphoma (B-ALL). This entity accounts for 10-20% of pediatric ALLs and 20-30% of adult cases.

There may be several additional … The most frequent copy number aberration in BCR/ABL1–like ALL is IKZF1 deletion, which is documented in approximately 27% of pediatric cases and in approximately 70% of high‐risk pediatric patients with ALL. 16 IKZF1 deletions initially were recognized as a negative prognostic marker both in patients with BCR/ABL1–positive and those with BCR/ABL1‐negative ALL. 7, 45-49 BCR/ABL1‐positive patients (100%) showed a common‐B ALL (BII) immunophenotype defined by positivity for CD10, which was also present on 84.6% of BCR/ABL1‐negative patients. Furthermore, CD34 was expressed in the totality of BCR/ABL1 ‐positive cases and on 73.1% of BCR/ABL1 ‐negative cases.

Another application for dPCR is molecular response monitoring in CML patients with atypical BCR-ABL1 transcripts, first demonstrated by Zagaria et al and recently used by the study group of Petiti et al. 53,54 After designing primers and probes flanking the different BCR-ABL1 breakpoints of atypical transcripts, they used a multiplex dPCR assay in which all BCR-ABL1 probes were labeled with

In the 2016 update of the World Health Organization (WHO) classification of hematopoietic neoplasms, BCR-ABL1-like B-acute lymphoblastic leukemia/lymphoma (B-ALL) is added as a new provisional entity that lacks the BCR-ABL1 translocation but shows a pattern of gene expression very similar to that seen in B-ALL with BCR-ABL1.

ABL therefore represents a crucial target for new therapeutic strategies. Here, we summarize the molecular pathways that are abnormally activated by the oncoprotein. Such pathways may provide additional opportunities to 2019-01-10 · Moreover, several atypical BCR-ABL1 transcripts, beside the most common e1a2, e13a2 and e14a2, have been described, mainly in patients with CML. However, ALL and de novo AML may also carry BCR-ABL1 atypical transcripts which will confer a poor prognosis.
