Inhibition of Janus-kinase 1/2 (JAK1/2) is a mainstay to treat myeloproliferative neoplasms (MPN). Sporadic observations reported the co-incidence of B-cell non-Hodgkin lymphomas during treatment of MPN with JAK1/2 inhibitors. We assessed 626 MPN patients including 69 with myelofibrosis receiving JAK1/2 inhibitors for lymphoma development. B-cell lymphomas evolved in 4/69 patients (5.8%) upon JAK1/2 inhibition compared to 2/557 (0.36%) with conventional treatment (16-fold increased risk). A similar 15-fold increase was observed in an independent cohort of 929 MPN patients...

Therapy-related acute lymphoblastic leukemia remains poorly defined due to a lack of large data sets recognizing the defining characteristics of this entity. We reviewed all consecutive cases of adult acute lymphoblastic leukemia treated at our institution between 2000 and 2017 and identified therapy-related cases-defined as acute lymphoblastic leukemia preceded by prior exposure to cytotoxic chemotherapy and/or radiation. Of 1022 patients with acute lymphoblastic leukemia, 93 (9.1%) were classified as therapy-related...

Aberrant expression of CD19 in acute myeloid leukemia (AML) is commonly associated with t(8;21)(q22;q22), although AML cases lacking this translocation occasionally express CD19. Mixed-phenotype acute leukemia also frequently expresses CD19. Chimeric antigen receptor (CAR) technology is a major breakthrough for cancer treatment, with the recent approval of CD19-directed CAR (CD19CAR) for treating B-cell malignancies. However, little information exists on using CD19CAR for other CD19 positive neoplasms such as AML...

Juvenile myelomonocytic leukemia (JMML) is an uncommon myeloproliferative neoplasm driven by Ras pathway mutations and hyperactive Ras/MAPK signaling. Outcomes for many children with JMML remain dismal with current standard-of-care cytoreductive chemotherapy and hematopoietic stem cell transplantation. We used patient-derived induced pluripotent stem cells (iPSCs) to characterize the signaling profiles and potential therapeutic vulnerabilities of PTPN11-mutant and CBL-mutant JMML. We assessed whether MEK, JAK, and PI3K/mTOR kinase inhibitors (i) could inhibit myeloproliferation and aberrant signaling in iPSC-derived hematopoietic progenitors with PTPN11 E76K or CBL Y371H mutations...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare disease with an aggressive clinical course resulting in median survival times of 12 to 14 months.1 It represents approximately 0.8% of primary cutaneous lymphomas.2 According to the World Health Organization Classification of Tumors of Hematopoietic and Lymphoid Tissue, published in 2008, BPDCN is defined as an acute myeloid leukemia related precursor neoplasm, derived from precursors of the plasmacytoid dendritic cell. It is characterized microscopically by its dense monomorphous infiltrates of medium-sized blastoid morphology and expression of CD4 and CD56, as well as the absence of any common myeloid, T-lymphoid, B-lymphoid, and natural killer-lymphoid lineage markers...

DISEASE OVERVIEW: Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic stem cell disorder with overlapping features of myelodysplastic syndromes and myeloproliferative neoplasms, with an inherent risk for leukemic transformation (∼15%-20% over 3-5 years). DIAGNOSIS: Diagnosis is based on the presence of sustained (>3 months) peripheral blood monocytosis (≥1 × 109 /L; monocytes ≥10%), along with bone marrow dysplasia. Clonal cytogenetic abnormalities occur in ∼ 30% of patients, while >90% have gene mutations...

Introduction: Infiltration of the central nervous system (CNS) by hematologic or lymphoid malignant cells can cause extensive neurological damage, be progressive and fatal. However, usually, the cerebrospinal fluid (CSF) has low cellularity and rapid cell degeneration, which can impair cytometry analysis. Storage and transport measures, sample preparation, and staining protocols can interfere with diagnostic accuracy. Objective: To calculate the diagnostic performance of flow cytometry (FC) using a cell stabilizer for sample preservation compared to cytomorphology in the detection of CNS infiltration by lymphoid and hematologic neoplasms...

Chromosome translocation t(16;21)(q24;q22)/RUNX1-RUNX1T3 is an infrequent but recurrent chromosomal abnormality identified in myeloid neoplasms, with only 25 cases have been reported to date. Here, we report eight cases (six women and two men) of myeloid neoplasms associated with t(16;21)(q24;q22): five with therapy-related myeloid neoplasms, two with relapsed acute myeloid leukemia (AML), and one with blast phase of chronic myeloid leukemia. Morphologic and immunophenotypic features include granulocytic dysplasia, blasts with prominent perinuclear hof, large orange-pink granules, long and slim Auer rods, and aberrant expression of CD19...

Therapeutic monoclonal antibodies (mAbs) such as antibody-drug conjugates, ligand-receptor antagonists, immune checkpoint inhibitors and bispecific T cell engagers have shown impressive efficacy in the treatment of multiple human cancers. Numerous therapeutic mAbs that have been developed for myeloid neoplasms, including acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), are currently investigated in clinical trials. Because AML and MDS originate from malignantly transformed hematopoietic stem/progenitor cells-the so-called leukemic stem cells (LSCs) that are highly resistant to most standard drugs-these malignancies frequently relapse and have a high disease-specific mortality...

Macrophages (MPs) are heterogeneous, multifunctional, myeloid-derived leukocytes that are part of the innate immune system, playing wide-ranging critical roles in basic biological activities, including maintenance of tissue homeostasis involving clearance of microbial pathogens. Tumor-associated MPs (TAMs) are MPs with defined specific M2 phenotypes now known to play central roles in the pathophysiology of a wide spectrum of malignant neoplasms. Also, TAMs are often intrinsic cellular components of the essential tumor microenvironment (TME)...

Limited data was available for long-term follow-up in newly diagnosed acute promyelocytic leukemia (APL) patients treated with all-trans-retinoic acid (ATRA) plus intravenously arsenic trioxide (ATO)-based front-line therapy. The aim of this work was to retrospectively analyze the long-term survival rate and frequency of therapy-related myeloid neoplasia (t-MN) occurring in a large cohort of APL patients. A total of 760 newly diagnosed patients with APL between January 1999 and May 2016 were evaluated. The early death rate was 9...

Various myeloid neoplasms, including the myelodysplastic syndromes (MDS), bear a certain risk of progression to secondary acute myeloid leukemia (sAML). The evolution from low-risk to high-risk MDS and finally to sAML suggests that leukemogenesis is a multistep process. However, even before an overt neoplasm, such as an MDS, develops, "prediagnostic" clonal conditions may be identified. With the advent of large-scale genomic screens, such conditions may be detected quite frequently and early in apparently healthy individuals...

Myeloid malignancies arise from the acquisition of somatic mutations among various genes implicated in essential functioning of hematopoietic stem cells and progenitor cells. In this second part of our two-part review, we discuss the use of mutation profiling in the diagnosis, prognosis, and treatment of patients with myeloproliferative neoplasms and other myeloid diseases. We also discuss the entity known as clonal hematopoiesis of indeterminate potential, awareness of which is a result of the increasing availability and improved quality of mutation profiling...

Myeloproliferative neoplasms (MPNs) are classically divided into BCR RhoGEF and GTPase activating protein (BCR)-ABL proto‑oncogene 1 non‑receptor tyrosine kinase (ABL) positive chronic myeloid leukemia (CML) and BCR‑ABL negative MPNs, including essential thrombocythemia (ET). One of the major diagnostic criteria for ET is the absence of the philadelphia chromosome, thus when present it is almost indicative of CML. ET and CML are considered to be mutually exclusive; however, there are rare situations in which patients with ET present positive BCR‑ABL without the features of CML...

BACKGROUND/AIMS: Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm. Tyrosine kinase inhibitors (TKIs) are commonly used to treat CML; however, drug resistance of CML cells to TKIs has limited their clinical application. Shikonin, a traditional Chinese herb, has long been used to treat leukemia in China, but the roles and related molecular mechanisms of shikonin treatment in CML remain unclear. Here, we aimed to evaluate the effects of shikonin on the proliferation, apoptosis, and migration of K562 cells, a CML cell line...

Neonatal leukaemia is defined as occurring within the first 28 days of life and most, if not all, cases are congenital. With the exception of Down syndrome-associated transient abnormal myelopoiesis, which is not considered here, neonatal leukaemias are rare. In two-thirds of patients the disease manifests as an acute myeloid leukaemia, frequently with monocytic/monoblastic characteristics. Most other cases are acute lymphoblastic leukaemia, particularly B lineage, but some are mixed phenotype or blastic plasmacytoid dendritic cell neoplasms...

Temozolomide (TMZ) is a second-generation oral alkylating agent that functions against a number of central nervous system neoplasms, and is generally used to treat high-grade gliomas, including anaplastic astrocytoma and glioblastoma multiforme. Therapy-related secondary myelodysplastic syndrome and acute myeloid leukemia have been reported in patients following prolonged exposure to TMZ. However, TMZ-related acute lymphoblastic leukemia (ALL) is extremely rare. The present study describes the case of an 11-year-old boy with a 3-day history of generalized tonic-clonic seizures and a contrast-enhanced lesion in the left temporooccipital region with focal cystic degeneration, as detected by magnetic resonance imaging...

Mitochondria are the powerhouses of the cell as well as the primary site of hematopoiesis, which also occurs in the cytoplasm. Hematopoietic stem cells (HSCs) are characterized by a very high turnover rate, and are thus considered to be relatively free from the age-related insults generated by mitochondria. However, HSCs are also subject to these age-related insults, including the incidence of myeloid proliferative diseases, marrow failure, hematopoietic neoplasms, and deterioration of the adaptive human immune system...

OBJECTIVE: To improve monitoring of myeloid neoplasms by flow cytometry-based minimal residual disease (MRD) analysis, we analyzed the significance of leukemia-associated immunophenotype (LAIP) markers in 44 patients. METHODS: In a pilot study cohort, peripheral blood or bone marrow samples from 13 patients with myeloid neoplasms and one case of B lymphoblastic leukemia in complete hematologic remission after allogeneic bone marrow or stem cell transplantation were subjected to selection for leukemia-specific phenotypes by fluorescence-activated cell sorting using individual marker combinations, followed by PCR-based chimerism analysis...
