Haznedaroglu, Nilgun Sayınalp, Osman Ozcebe, Umit Yavuz Malkan, Hakan GokerAbstractBackground and AimThe refractory acute myeloid leukemia (AML) includes patients who fail standard induction chemotherapy, relapse within 6 months after first complete remission and relapse twice or more. The outcome of these patients is usually very poor with only a small proportion could be rescued by allogenic hematopoietic stem cell transplan...
In this study we explored whether microvessel density, a biomarker of angiogenesis, might be relevant in MS. We studied 60 MS, 24 acute myeloid leukemia, 5 normal bone marrow samples and 2 cases of extramedullary hemopoiesis in patients without evidence of hematological malignancy. We used immunohistochemistry (anti-CD34) to identify and quantify micro-vessel density (MVD) and micro-vessel grading (MVG). We found that MS had significantly higher MVD and MVG than normal bone marrow (p = 0.0002 and p
This study aimed to evaluate the significance of dynamic MRD pretransplantation on outcome of AML patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: We retrospectively analyzed 145 consecutive AML patients undergoing allo-HSCT in complete remission status between June 2013 and June 2016. MRD was determined with multiparameter flow cytometry after the first and second courses of chemotherapy and pre-HSCT. Results: In matched sibling donor transplantation (MSDT) settings, patients with positive MRD had higher cumulative incidence of relapse (CIR) than those without MRD after...
The refractory acute myeloid leukemia (AML) includes patients who fail standard induction chemotherapy, relapse within 6 months after first complete remission and relapse twice or more. The outcome of these patients is usually very poor with only a small proportion could be rescued by allogenic hematopoietic stem cell transplantation (alloHSCT). The aim of this study is to evaluate the efficacy and feasibility of alloHSCT in patients with refractory AML.
Immunotherapy has revolutionized therapy in both solid and liquid malignancies. The ability to cure acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) with an allogeneic hematopoietic stem cell transplant (HSCT) is proof of concept for the application of immunotherapy in AML and MDS. However, outside of HSCT, only the anti-CD33 antibody drug conjugate gemtuzumab ozogamicin is currently approved as an antibody-targeted therapy for AML. Several avenues of immunotherapeutic drugs are currently in different stages of clinical development.
Allogeneic hematopoietic stem cell transplantation could improve outcomes of elderly patients with acute myeloid leukemia.
Acute myeloid leukemia (AML) is a heterogeneous disease of varying prognosis. Chromosomal aberrations are found in approximately 55% of adult patients with AML and have high prognostic significance in patient response to therapy, risk of relapse, and overall survival [1 –4]. Three cytogenetic risk groups are currently in use: favorable, intermediate, and adverse. Adverse cytogenetic risk group is largely homogenous and generally includes abnormalities of 3q (i.e. inv(3q), t(3;3), 5q/-5, 7q/-7, abn(17p), t(6;9), 11q23 [except t(9;11)] and complex karyotypes .
Purpose of review Glycogen storage disease Ib (GSD Ib) is characterized by hepatomegaly, hypoglycemia, neutropenia, enterocolitis and recurrent bacterial infections. It is attributable to mutations in G6PT1, the gene for the glucose-6-phosphate transporter responsible for transport of glucose into the endoplasmic reticulum. Neutropenia in GSD Ib is now frequently treated with granulocyte colony-stimulating factor (G-CSF). We formed a cooperative group to review outcomes of the long-term treatment of GSD Ib patients treated with G-CSF. Recent findings The study enrolled 103 patients (48 men and 55 women), including 47 ...
CONCLUSIONS: Myeloablative haplo-HSCT with ATG+G-CSF is superior to chemotherapy as a postremission treatment in patients with int-risk AML during CR1. Haplo-HSCT might be a first-line postremission therapy for int-risk AML in the absence of MSDs. PMID: 30478089 [PubMed - as supplied by publisher]
