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 wiht tyrosine kinase inhibitors (TKI) such as Imatinab and second generation TKIs [14,15].

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].
