Genetic alterations, including mutations and copy number alterations, are central to the pathogenesis of myelodysplastic syndromes and related diseases (myelodysplasia), but their roles in allogeneic stem-cell transplantation have not fully been studied in a large cohort of patients. We enrolled 797 patients who had been diagnosed with myelodysplasia at initial presentation and received transplantation via the Japan Marrow Donor Program. Targeted-capture sequencing was performed to identify mutations in 69 genes, together with copy number alterations, whose effects on transplantation outcomes were investigated...

BACKGROUND: Ewing sarcoma survivors (ESSs) are at increased risk for treatment-related complications. The incidence of treatment-related morbidity and late mortality with aging is unknown. METHODS: This study reports survival probabilities, estimated with the Kaplan-Meier method, and the cumulative incidence of cause-specific mortality and chronic conditions among ESSs in the Childhood Cancer Survivor Study who were treated between 1970 and 1986. Piecewise exponential models were used to estimate relative rates (RRs) and 95% confidence intervals (CIs) for these outcomes...

BACKGROUND PDGFRᵝ-positive myeloid neoplasms are rare. Marked leukocytosis (over 100×10⁹/L) with marked eosinophilia (over 10%) has been rarely described in myeloid neoplasms associated with PDGFRᵝ rearrangement. CASE REPORT We report a case of 37-year-old man with myeloid neoplasm associated with PDGFRᵝ rearrangement who presented with marked eosinophilia of 13.3% and leukocytosis with WBC count of 189×10⁹/L. He was found to have PDGFRᵝ locus rearrangement at 5q32-33 by fluorescent in situ hybridization (FISH)...

Sweet's syndrome (SS) is a rare condition characterized by the abrupt appearance of painful skin lesions due to neutrophilic dermal infiltration. Hematologic neoplasms, particularly acute myeloid leukemia (AML) and myelodysplastic syndromes (MDSs), have been commonly reported in association with SS. Clonal hematopoiesis of indeterminate potential (CHIP) is an emerging entity that is a precursor state to myeloid neoplasms. CHIP has not been previously associated with SS. We report the case of a 71-year-old man who presented with recurrent, painful edematous and erythematous papules and nodules for 18 months despite treatment with corticosteroids...

Pulmonary alveolar proteinosis (PAP) is classified as autoimmune, secondary, or genetic. We herein describe a 69-year-old man with autoimmune PAP, simultaneously diagnosed with myeloproliferative neoplasm (MPN). Two years after the diagnosis, the MPN progressed to acute myeloid leukemia, and the patient died from an alveolar hemorrhage during remission induction chemotherapy. Throughout the clinical course, no progression of PAP was observed, despite the progression to leukemia. There are few reports of autoimmune PAP with hematological malignancy, and this case demonstrated that an evaluation for GM-CSF autoantibodies is important for distinguishing the autoimmune and secondary forms of PAP, even if the patient has hematological malignancy...

We reviewed 97 consecutive cases of myeloid neoplasm with erythroid predominance (MN-EP) between 2000 and 2015. Following 2016 WHO classification, MN-EP patients were classified into four groups. Eight pure erythroid leukemia (PEL) (including t-MN and AML-MRC morphologically fulfilled criteria for PEL) patients had dismal outcomes (median OS: 1 month) and showed more bone marrow fibrosis, worse performance status (PS) and higher serum lactate dehydrogenase (LDH) at diagnosis than the other groups. In the univariate analysis, risks of death in MN-EP patients included the morphologic features of PEL, very poor cytogenetic risk by IPSS-R, bone marrow fibrosis, leukocytosis, anemia, hypoalbuminemia, high LDH, and poor PS...

Myelosysplastic syndromes (MDS) include a heterogeneous group of clonal myeloid neoplasms characterized by ineffective hematopoiesis leading to blood cytopenias and a variable risk of progression into acute myeloid leukemia (AML). Although the hypomethylating agent azacitidine prolongs survival among patients with higher risk (HR)-MDS compared with conventional care, no drug has been shown conclusively to prolong survival or delay progression to AML among patients with lower-risk MDS (LR-MDS). Lenalidomide is the drug with the most impressive clinical activity in the subset of anemic LR-MDS patients who harbor a deletion of the long arm of chromosome 5 (5q-), where it leads to high rates of transfusion independence and cytogenetic responses...

Two distinct forms of neoplasms derived from plasmacytoid dendritic cells (PDC) exist: mature PDC proliferations associated with myeloid neoplasms and blastic PDC neoplasms (BPDCN). Ten cases of PDC proliferations and neoplasms in the bone marrow have been submitted to the bone marrow workshop held at the 18th EAHP meeting. Based on observations from the submitted cases, scattered PDC (≤1% of cells) and PDC aggregates (≤10 PDC/HPF) reflect the normal bone marrow composition, while in myelodysplastic syndromes (MDS), there is a propensity for larger/more PDC aggregates (1-5% and 35 PDC/HPF)...

A 69-year-old man diagnosed with leukocytosis was referred to our hospital in July 201X. The patient was diagnosed as having a myelodysplastic/myeloproliferative neoplasm. However, he presented with leukemia 2 months later. Chromosomal analysis of a bone marrow sample documented that this patient had a normal karyotype. The patient was successfully treated with idarubicin and cytarabine, and he underwent three courses of consolidation therapy. However, he suffered a relapse in May of the following year. A cytogenetic analysis revealed the presence of a t (3;21) (q13;q22) translocation, and fluorescence in situ hybridization of metaphase spreads detected three signals corresponding to the runt related transcription factor 1 (RUNX1) on the derivative chromosomes 3 and 21, besides the normal chromosome 21...

DISEASE OVERVIEW: Ring sideroblasts (RS) are erythroid precursors with abnormal perinuclear mitochondrial iron accumulation. Two myeloid neoplasms defined by the presence of RS, include refractory anemia with ring sideroblasts (RARS), now classified under myelodysplastic syndromes with RS (MDS-RS) and RARS with thrombocytosis (RARS-T); now called myelodysplastic/myeloproliferative neoplasm with RS and thrombocytosis (MDS/MPN-RS-T). DIAGNOSIS: MDS-RS is a lower risk MDS, with single or multilineage dysplasia (SLD/MLD), <5% bone marrow (BM) blasts and ≥15% BM RS (≥5% in the presence of SF3B1 mutations)...

Myeloproliferative neoplasms (MPN) are a group of disorders defined by clonal proliferation of mature myeloid cells with overlapping clinical features. The driver mutations of these disorders, namely JAK2 (Janus Kinase), MPL (Myeloproliferative Leukaemia Virus) and CALR (Calreticulin) upregulate JAK-STAT signaling with increase in downstream transcription and gene expression. Epigenetic mutations are prevalent in MPNs but their interplay with aberrant JAK-STAT signaling is not known. This understanding lead to development of first targeted treatment in MPN; ruxolitinib for primary myelofibrosis...

Myeloproliferative neoplasms (MPN) arise in the hematopoietic stem cell (HSC) compartment as a result of the acquisition of somatic mutations in a single HSC that provide a selective advantage to mutant HSC over normal HSC and promote myeloid differentiation to engender a myeloproliferative phenotype. This population of somatically mutated HSC, which initiate and sustain MPN, are termed MPN stem cells. In greater than 95% of cases, mutations that drive the development of an MPN phenotype occur in a mutually exclusive manner in one of three genes: JAK2, CALR or MPL The thrombopoietin receptor, MPL is the key cytokine receptor in MPN development and these mutations all activate MPL-JAK-STAT signaling in MPN stem cells...

Similar to their healthy counterpart, malignant hematopoietic stem cells in myeloid malignancies such as myeloproliferative neoplasms (MPNs), myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), reside in a highly complex and dynamic cellular microenvironment in the bone marrow. This environment provides key regulatory signals for and tightly controls cardinal features of HSCs, including self-renewal, quiescence, differentiation and migration. These features are essential to maintaining cellular homeostasis and blood regeneration throughout life...

BACKGROUND: Patients diagnosed with therapy-related myeloid neoplasms (TRMN) with concomitant active neoplastic disorder (CAND) are usually proposed for best supportive care (BSC). We evaluated the feasibility of using 5-azacytidine (AZA) in this setting. METHODS: All patients referred to Gustave Roussy between 2010 and 2015 for TRMN diagnosis (less than 30% blast) and eligible for AZA treatment were included. Patients with CAND proposed for BSC were also described...
