Studies of axitinib and axitinib drug combinations as BCR-ABL1 T315I -selective therapies for use in drug-resistant CML and Ph+ ALL. Wennerberg, Krister

Ph-like ALL is a unique subtype of B-cell ALL with a gene expression signature similar to that of ALL bearing the BCR-ABL1 fusion, but lacking that specific translocation. Patients with Ph-like ALL have a very poor prognosis, but respond well to targeted therapy if the proper molecular feature can be identified.

The 20-mL droplet digital PCR (ddPCR) reaction mixture was then loaded into the Bio-Rad DG8 disposable droplet generator cartridge.A volumeof Table 1 Primer and Probe Sequences for BCR-ABL1 and BCR Transcripts BCR‐ABL1‐like B‐lymphoblastic leukemia/lymphoma (BCR‐ABL1‐like B‐ALL), also known as Philadelphia‐like (Ph‐like) ALL, is a neoplasm of B‐lineage lymphoblasts characterized by a pattern of gene expression similar to that of B‐ALL with the BCR‐ABL1 translocation but lacking the BCR‐ABL1 … Clinical Significance. BCR-ABL1 Gene Rearrangement, Quantitative, PCR - The Philadelphia Chromosome (Ph) is a translocation between chromosome 9 and 22 t (9; 22) (q34; Q11) that is found in more than 90-95% of chronic myeloid leukemia (CML), and in 20-25% of adult and 2-10% of childhood acute lymphoblastic leukemia (ALL). Quantitative – Quantitative BCR-ABL1 Translocation Detection by RT-PCR for CML and ALL. Clinical Use: This assay can detect three different types of BCR-ABL1 fusion transcripts associated with CML, ALL, and AML:e13a2 (previously b2a2) and e14a2 (previously b3a2) (major breakpoint, p210), as well as e1a2 (minor breakpoint, p190). The PCR primers and probes are specific for BCR-ABL1 e13a2, e14a2 and e1a2 fusion transcripts.

A recipient An increasing BCR-ABL1/ABL1 ratio may indicate a poor initial response or a secondary loss of response to TKI therapy (disease recurrence) in Ph+ ALL patients. Evaluation of ABL1 kinase domain mutations in recurrent Ph+ ALL can help guide changes in TKI therapy. 6 BCR-ABL1 mutations may cause resistance to tyrosine kinase inhibitor (TKI) therapy in patients with either chronic myelogenous leukemia (CML) or Philadelphia chromosome positive (Ph+) acute lymphoblastic leukemia (ALL). Testing should be performed for patients with an established diagnosis of a BCR-ABL1-positive leukemia to guide treatment BCR-ABL1 testing is requested to detect the Philadelphia (Ph) chromosome or the BCR-ABL1 gene sequence. It is used to: Help diagnose chronic myelogenous leukaemia (CML), a type of acute lymphoblastic leukaemia (ALL) or very rarely another type of leukaemia called acute myeloid leukaemia Results.

The presence of the gene sequence known as BCR-ABL1 confirms the diagnosis of CML and a form of acute lymphoblastic lymphoma (ALL), specifically a type of B-lymphoblastic leukemia/lymphoma. In very rare cases, the abnormal chromosome is linked to cases of acute myeloid leukemia and T-lymphoblastic leukemia/lymphoma.

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

It has two-step protocol in which total RNA is reverse-transcribed, and the generated cDNA is amplified by PCR using a pair of specific primers and a specific internal double-dye probe of BCR-ABL1 (Major, Minor BCR‐ABL1‐like B‐ALL is a common subtype of B‐ALL, representing 7% to 25% of new diagnoses.

BCR-ABL1 quantitative testing is recommended for patients with either chronic myelogenous leukemia (CML), a hematopoietic stem cell disease, or acute lymphoblastic leukemia (ALL), an aggressive type of leukemia of either B- or T-lineage immature lymphoid cells. 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.

The BCR blood test, which is formally called the BCR-ABL1 test, looks for a specific gene sequence that is found with an abnormal chromosome 22 in some individuals who have certain forms of leukemia. Testing can detect what is called the Ph, or Philadelphia, chromosome and the BCR-ABL1 gene sequence. There may be several additional …
