Oral azacitidine maintenance therapy for post-transplant AML

Relapse remains the main obstacle for patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) after allogeneic stem cell transplantation and novel therapeutic strategies are urg... Author: VJHemOnc Added: 12/18/2017

AbstractPrimary graft failure can be a cause of early morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT), as it leads to a high risk of severe infections and bleeding. Splenomegaly is associated with primary graft failure in patients of myelofibrosis, but the association between splenomegaly and outcomes after HSCT in patients with myeloid malignancies has not been previously evaluated. The aim of this study was to investigate the effect of spleen volume on engraftment kinetics in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). We enrolled 85 patients. The...

A 62-year-old man with acute myeloid leukemia, evolved from myelodysplastic syndrome after allogeneic bone marrow transplant, was admitted to the hospital because of worsening fatigue and altered level of consciousness. On arrival at the hospital, the patient was markedly fatigued and had signs of encephalopathy. He reported no fevers, chills, or diaphoresis but noted new urinary incontinence and nausea. His medical history was notable for a matched unrelated donor allogeneic hematopoietic stem cell transplant (HCT), performed 35 days previously, as well as hypertension and peripheral vascular disease.

Pediatric myelodysplastic syndromes (MDSs) are a heterogeneous group of clonal disorders with an annual incidence of 1 to 4 cases per million, accounting for less than 5% of childhood hematologic malignancies. MDSs in children often occur in the context of inherited bone marrow failure syndromes, which represent a peculiarity of myelodysplasia diagnosed in pediatric patients. Moreover, germ line syndromes predisposing individuals to develop MDS or acute myeloid leukemia have recently been identified, such as those caused by mutations in GATA2, ETV6, SRP72, and SAMD9/SAMD9-L. Refractory cytopenia of childhood (RCC) is the m...

Abstract Patient-derived xenotransplantation models of human myeloid diseases including acute myeloid leukemia, myelodysplastic syndromes and myeloproliferative neoplasms are essential for studying the disease's biology in pre-clinical studies. However, few studies have used these models for comparison purposes. Previous work has shown that acute myeloid leukemia blasts respond to human hematopoietic cytokines whereas myelodysplastic syndrome cells do not. We compared the engraftment of acute myeloid leukemia cells and myelodyplastic syndrome cells in NSG mice to NSG-S mice, which have transgene expression of huma...

ConclusionDe novo myeloid sarcoma mostly presented isolated. Lesions were often localized at skin and lymph nodes. Genetic aberrations frequently involved coreā€binding factor rearrangements in de novo cases and a complex karyotype in secondary cases.This article is protected by copyright. All rights reserved.

DISCUSSION: Treatment with chemotherapy plus G-CSF appears to provide better survival and treatment responses compared with chemotherapy alone, particularly for patients with previously untreated AML. ABBREVIATIONS: AML, acute myeloid leukemia; CI, confidence interval; CR, complete remission; DFS, disease-free survival; G-CSF, granulocyte colony-stimulating factor; GM-CSF, granulocyte macrophage colony-stimulating factor; HR, hazard ratio; MDS, myelodysplastic syndrome; OR, odds ratio; OS, overall survival; RCTs, randomized control trials; RR, relative risk.

Myelodysplastic syndromes (MDS) encompass a heterogeneous group of malignant hematopoietic stem cell disorders characterized by dysplastic and ineffective blood cell production, leading to significant cytopenia and a variable risk of transformation to acute myelogenous leukemia (AML) [1].

In 2011, 4 groups described a new human disease syndrome, now termed GATA2 deficiency, resulting from heterozygous germline or sporadic mutations in the transcription factor GATA2. Each group approached this syndrome from a distinct clinical perspective, resulting in 4 different names for processes caused by the same genetic abnormality: autosomal dominant and sporadic monocytopenia and Mycobacterium avium complex (MonoMAC); dendritic cell, monocyte, B, and natural killer (NK) lymphoid deficiency; Emberger syndrome (lymphedema and monosomy 7); and familial myelodysplastic syndrome (myelodysplastic syndrome [MDS]/acute myel...
