Treatment of Acute Lymphoblastic Leukemia patients with Gleevec does not have the same success as in Chronic Myeloid Leukemia patients because the genomic instability of ALL cells contributes to point mutations arising in the BRC-ABL1 kinase domain, leading to Gleevec resistance [4]. |

Cancer Category/Type
Chronic Myeloid Leukemia with BCR-ABL1 (also referred as (Chronic Myelogenous Leukemia))
More than 90% of patients diagnosed with Chronic Myeloid Leukemia have a Philadelphia chromosome resulting from t(9;22)(q34.1;q11.2), which is a reciprocal translocation between chromosome 22 (BCR locus) and chromosome 9 (ABL1 locus) (see OMIM) [1]. The Drug Imatinib mesylate, also known as Gleevec, was the one of the first molecularly developed drugs, and has a remarkably high success rate in treatment of patients with Chronic Myeloid Leukemia by targeting the BCR/ABL1 fusion product [5].
Approximately 20% of patients (25 - 30% of adults and 2 - 10% of children) diagnosed with Acute Lymphoblastic Leukemia have a Philadelphia chromosome resulting from t(9;22)(q34.1;q11.2), which is a reciprocal translocation between chromosome 22 (BCR locus) and chromosome 9 (ABL1 locus) (see OMIM) [1]. Treatment of Acute Lymphoblastic Leukemia patients with Gleevec does not have the same success as in Chronic Myeloid Leukemia patients because the genomic instability of ALL cells contributes to point mutations arising in the BRC-ABL1 kinase domain, leading to Gleevec resistance [4].
Mixed Phenotype Acute Leukemia (MPAL) with BCR-ABL1
BCR-ABL1 translocations (Ph+) are more prevalent in adult vs. pediatric patients diagnosed as Mixed Phenotype Acute Leukemia (MPAL) [12,13]. The BCR-ABL1 translocations are considered to be prognostic of poorer outcomes in the context of patients diagnosed with Mixed Phenotype Acute Leukemia (MPAL) [12]. However, a number of individual studies indicate that Ph+ MPAL patients can be treated successfully with tyrosine kinase inhibitors (TKI) such as Imatinab and second generation TKIs [14,15].
Acute Myeloid Leukemia with BCR-ABL1
This rare entity, accounting for <1% of AML and <1% of BCR-ABL1 positive acute and chronic leukemias, typically occurs in adults. AML with BCR-ABL1 is aggressive with poor response to traditional AML therapy or isolated tyrosine kinase (TK) therapy alone; TK therapy with subsequent allogeneic hematopoietic cell transplantation may improve survival [16].
Gene Overview
The ABL1 gene encodes a non-receptor tyrosine kinase that is ubiquitously expressed and involved in a large number of cellular processes (see "NCBI Gene). By far the most prevalent ABL1 alteration associated with cancer are the fusions of the ABL1 gene with a number of partners, but especially with the BCR gene in CML [1,2] and to a lesser extent in B-ALL and T-ALL. The head to tail arrangement of the BCR-ABL1 fusion gene results in an activated tyrosine kinase activity [6]. It appears that the N-terminal domain of BCR can cause oligomerization of the BCR-ABL1 protein product, thus activating the ABL1 tyrosine kinase domain of the fusion protein [6,10,11]. The ABL1 and ABL2 genes encode tyrosine kinases which share overlapping physiological roles, and ABL2 somatic or amplification mutations are more common than similar mutations in ABL1 [6].
See the "BCR gene" for additional details of the BCR-ABL1 gene fusion.
Common Alteration Types
By far the most common ABL1 alteration associated with cancer is the BCR-ABL1 fusion as described above in CML and ALL.
A number of other gene fusion partners have been identified with ABL1 that are linked to hematological cancers, but at a much smaller prevalence than BCR-ABL1.
- NUP214-ABL1 (associated with T-cell Acute Lymphoblastic Leukemia).
- ETV6-ABL1 (associated with Chronic Myeloid Leukemia, T-cell Acute Lymphoblastic Leukemia, B-cell Acute Lymphoblastic Leukemia and Acute Myeloid Leukemia), and EML (associated with T-cell Acute Lymphoblastic Leukemia).
Somatic mutations for ABL1 have been found in Lung Squamous Cell Carcinomas patients (2%), Uterine Corpus Endometrioid Carcinoma patients (3%) and in less than 1% of patients with Breast Invasive Carcinoma, Ovarian Serous Cystadenocarcinoma, and Lung Adenocarcinoma [6].
Resistance to tyrosine kinase inhibitors (e.g., Gleevec) are attributed to secondary mutations within the tyrosine kinase domain of ABL1, especially the "gatekeeper" T315I residue mutation [7,8].
