Role of Post-Allogeneic Hematopoietic Stem Cell Transplantation Low-Dose Azacitidine for Prevention of Relapse in Patients with Acute Myeloid Leukemia and Myelodysplastic Syndrome: A Retrospective Analysis

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.

Abstract The tumor suppressor p53 exerts pivotal roles in hematopoietic stem cell (HSC) homeostasis. Mutations of the TP53 gene have recently been described in individuals with clonal hematopoieis conferring substantial risk of developing blood cancers. In patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), TP53 aberrations - mutations, deletions and a combination thereof - are encountered at a constant frequency of approximately 10%. These aberrations affect HSCs transforming them into preleukemic stem cells, pinpointing their central role in leukemogenesis. AML and MDS with TP53 aberr...

Kobbe Thomas Schroeder To provide long-term outcome data and predictors for response and survival, we retrospectively analyzed all 151 patients with relapse of myeloid neoplasms after allogeneic hematopoietic stem cell transplantation (allo-HSCT) who were uniformly treated with first-line azacitidine (Aza) salvage therapy at our center. Patients were treated for molecular (39%) or hematologic relapse (61%), with a median of 5 cycles of Aza and at least one donor lymphocyte infusion in 70% of patients. Overall response was 46%, with 41% achieving complete (CR) and 5% achieving partial remission. CR was achieved after ...

We compared the transplant outcomes between HID and MSD transplants for AML and MSD aged ≥50 years. The results showed that HID transplant is feasible and safe for elderly AML/MDS patients. AbstractAllogeneic hematopoietic stem cell transplantation (allo ‐HSCT) is a potentially curative therapeutic option for patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Increasing data suggest that haploidentical donor (HID) transplantation achieve comparable outcomes with HLA‐matched sibling donor (MSD) in adult AML/MDS. This re trospective study compared the outcomes of AML or MDS patients age ...

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...

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.
