Affected individuals have an increased susceptibility to the development of hematologic malignancies, and possibly to solid neoplasms. Thrombocytopenia is usually apparent in early childhood, whereas the development of malignancy can occur throughout life summary by Zhang et al. For a discussion of genetic heterogeneity of thrombocytopenia, see Zhang et al. In 1 family, a mother and her 3 children of German and Native American origin all had thrombocytopenia. Two patients had neutropenia and 2 had anemia. The proband was 1 of 2 daughters who presented with easy bruising in infancy and menorrhagia in the teenage years. The proband developed myelodysplastic syndrome at age 17 and underwent hematopoietic stem cell transplant HSCT. Her sister developed B-cell acute lymphocytic leukemia ALL at age 7. The mother had a history of 5 miscarriages.

Mixed phenotype acute leukemia MPAL is a rare subtype of acute leukemia characterized by leukemic blasts presenting myeloid and lymphoid markers. Myeloid-B and myeloid-T MPAL show distinct mutation and methylation signatures that are associated with differences in lineage-commitment gene expressions. Acute leukemia is a clonal hematopoietic malignancy that is characterized by increased proliferation and disorganized differentiation of hematopoietic cells. Although acute leukemia generally presents with either a myeloid or lymphoid lineage, rare cases present with blasts that show immunophenotypes of both myeloid and lymphoid lineages bi-phenotypic or with multiple blasts each having different lineage of immunophenotypes bi-lineal. Because of the rarity of the disease and the mixed phenotype presentation, standard therapy for MPAL has not been clearly defined, leading to inconsistency in treatment choices between AML-directed regimens and ALL-directed regimens 3 , 4.

Recent advances in the small field of the rare mixed phenotype acute leukemias MPAL are presented focusing on a better understanding of their pathophysiology and search for better therapeutic approaches. Three aspects of respective classification, therapy, and immunophenotype of MPAL are reviewed. New proposals have been made to segregate MPAL subtypes based on their genomic landscape. In parallel, it was found that a large array of therapeutic approaches has been tested in the past few years with increasingly good results. Finally, we explored the use of unsupervised flow cytometry analysis to dissect subtle variations in markers expression to better characterize the variegating aspect of MPALs. Genomic and immunophenotypic aspects more clearly link MPAL subtypes with bona fide acute myeloblastic of lymphoblastic leukemias. This is likely to impact therapeutic strategies, towards a better management and outcome.

Mixed-phenotype acute leukemia MPAL is a rare type of blood cancer. Typically, a doctor can classify the cancer as acute myeloid leukemia AML or acute lymphoblastic leukemia ALL , depending on the cells involved.
