Genetic testing helps predict disease recurrence in myelodysplastic syndrome

(Washington University School of Medicine) A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells, according to new research at Washington University School of Medicine in St. Louis. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.

our M Abstract Microtransplantation (MT) is based on injection of HLA-mismatched G-CSF mobilized hematopoietic stem cells, in combination with chemotherapy but without use of conditioning regimen nor immunosuppressive drugs. As a result, a transient microchimerism is induced without engraftment. Its efficacy relies both on host immune system stimulation (recipient versus tumor) and on a graft versus tumor effect. Data are scarce and concern mostly Asian patients with acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (HR-MDS). In comparison to conventional treatment without MT, higher complete rem...

g P Abstract The myelodysplastic syndromes (MDS) share an origin in the hematopoietic stem cell but have otherwise very heterogeneous biological and genetic characteristics. Clinical features are dominated by cytopenia and substantial risk for progression to acute myeloid leukemia. According to the World Health Organisation (WHO) MDS is defined by cytopenia, bone marrow dysplasia, and by certain karyotypic abnormalities. The understanding of disease pathogenesis has undergone major development with the implementation of next generation sequencing, and a closer integration of morphology, cytogenetics and molecular ...

Authors: Gorshein E, Weber UM, Gore S Abstract Introduction: Myelodysplastic Syndrome (MDS) represents a group of cancers characterized by abnormal blood cell formation and maturation, leading to various degrees of cytopenias and potential transformation to acute myeloid leukemia. Deletion of the long arm of chromosome 5 (del(5q)) is the most common clonal chromosomal anomaly in MDS, yet the population in this disease subtype is quite heterogeneous. This manuscript analyzes literature on high-risk MDS with del(5q) abnormalities.Areas covered: The paper will review outcomes with lenalidomide among high-risk MDS pati...

Relapse after allogeneic hematopoietic stem cell transplantation (HSCT) for acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) remains a major cause of treatment failure with associated poor prognosis. Low-dose post-HSCT maintenance azacitidine (AZA) has proved to be beneficial in preventing relapses (de Lima et al. Cancer 2010). Herein, we retrospectively evaluated outcomes of patients (pts) treated with low-dose AZA post-HSCT.

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons. Epige...

ConclusionsOral complications in HSCT survivors are common and may include GVHD, dry mouth, and taste changes. All patients must be screened prior to HSCT and followed up by a dentist periodically to assess the oral health status and modify treatment, if needed.

Acute myeloid leukemia (AML) represents 80% of adult leukemias and 15–20% of childhood leukemias. AML are characterized by the presence of 20% blasts or more in the bone marrow, or defining cytogenetic abnormalities. Laboratory diagnoses of myelodysplastic syndromes (MDS) depend on morphological changes based on dysplasia in peripheral blood and bone marrow, including peripheral blood smears, bone marrow aspirate smears, and bone marrow biopsies. As leukemic cells are not functional, the patient develops anemia, neutropenia, and thrombocytopenia, leading to fatigue, recurrent infections, and hemorrhage. The genetic b...
