Alternative titles; symbols. Thrombocytopenia-5 is an autosomal dominant disorder characterized by a decreased number of platelets and a bleeding tendency. 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.

Nathan J. Charles , Daniel F. Arch Pathol Lab Med 1 November ; 11 : — Flow cytometric findings suggestive of MPAL are often met with consternation by pathologists and oncologists alike, owing to unfamiliarity with the disease and uncertainty about how MPAL fits into established paradigms for treatment of acute leukemia. The purpose of this review is to explain the diagnostic criteria for MPAL, summarize its biological and clinical features, and address common diagnostic pitfalls of these unusual leukemias. The first step in classification of acute leukemia is to assign lineage by resemblance to normal progenitor cells. This approach provides descriptive information about the blast cells that is useful for disease monitoring, provides clues to molecular pathways involved in pathogenesis, and can help to select effective chemotherapeutic regimens.

Ofir Wolach , Richard M. Stone; How I treat mixed-phenotype acute leukemia. Blood ; 16 : — Mixed-phenotype acute leukemia MPAL encompasses a heterogeneous group of rare leukemias in which assigning a single lineage of origin is not possible. A variety of different terms and classification systems have been used historically to describe this entity. MPAL is currently defined by a limited set of lineage-specific markers proposed in the World Health Organization monograph on classification of tumors of hematopoietic and lymphoid tissues. In adult patients, MPAL is characterized by relative therapeutic resistance that may be attributed in part to the high proportion of patients with adverse cytogenetic abnormalities. No prospective, controlled trials exist to guide therapy. The role of immunophenotypic and genetic markers in guiding chemotherapy choice and postremission strategy, as well as the utility of targeted therapies in non—Ph-positive MPALs is unknown. The absence of essentially any useful prospectively collected data on how to treat mixed-phenotypic acute leukemia MPAL in adults both simplifies and complicates any discussion of this topic.
