Background: So many risk factors for mobilization failure have been described so far. We aimed to identify the risk factors and search the possible effects of bone marrow fibrosis (BMF), CD56, c-myc, and cyclinD1 expression on mobilization.

Methods: We evaluated 189 patients with MM who were admitted for stem cell mobilization before autologous stem cell transplantation (ASCT) between 2015 and June 2021.

Introduction: Secondary hemophagocytic syndrome (HPS) and systemic inflammatory response syndrome (SIRS) share similar clinical findings as a result of hyperinflammation. Due to high mortality rates in HPS; it is critical to diagnose promptly. Thus, this study aimed to evaluate the diagnostic and prognostic significance of inflammatory markers in these two increased inflammatory states.

Objective: Although inhibition of the complement system at different steps is a promising therapy modality in patients with paroxysmal nocturnal hemoglobinuria (PNH), allogeneic hematopoietic stem cell transplantation (HCT) is still the only curative therapy, especially for patients with intractable hemolysis or bone marrow failure. The aim of this study is to evaluate the outcomes of allogeneic HCT in PNH patients with aplastic anemia (PNH-AA) or without.

Materials And Methods: Thirty-five PNH/PNH-AA patients who were treated with allogeneic HCT in 10 transplantation centers in Turkey were retrospectively analyzed.

Hepatic sinusoidal obstruction syndrome (HSOS) is a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). We retrospectively evaluated the incidence, risk factors, treatment and survival for HSOS after allo-HSCT in Turkey. We also reported our experience of defibrotide (DF) for HSOS prophylaxis in high-risk (HR) patients.

Objective: Tyrosine kinase inhibitors (TKIs) which efficiently inhibit BCR-ABL are highly effective for clinical treatment of chronic myeloid leukemia (CML), but development of resistance to TKIs is a big challenge to treatment. Sunitinib is a multitargeted TKI targeting vascular endothelial growth factor receptor and is defined a safe and effective candidate target, but its effect on other signaling pathways is unknown. To investigate the cytotoxic and apoptotic effect of sunitinib in CML cell model K-562 on JAK-STAT signaling pathway components, suppressor genes and oncogenes, hematopoiesis-related genes, cell cycle and VEGF pathway components, and mRNA level expression changes was aimed.

Objective: This study aimed to evaluate real-life data on patterns of hydroxyurea prescription/use in polycythemia vera (PV).

Materials And Methods: This retrospective chart review study included PV patients who had received hydroxyurea therapy for at least 2 months after PV diagnosis. Data were collected from 10 representative academic medical centers.

Background/aim: In Turkey, lenalidomide plus dexamethasone (RD) has been used to treat relapsed/refractory multiple myeloma (RRMM) since 2010. This retrospective, single-center study evaluated the efficacy and tolerability of RD in patients with RRMM between October 2010 and June 2016.

Materials And Methods: Patients’ records were reviewed, and overall (OS) and progression-free survival (PFS) were assessed.

Objectives: The aim of our study was to evaluate the efficacy and toxicity of TECAM (thiotepa, etoposide, cyclophosphamide, cytarabine, and melphalan) and BEAM (carmustine, etoposide, cytarabine, and melphalan) conditioning regimens before autologous hematopoietic stem cell transplant in patients with lymphoma.

Materials And Methods: We retrospectively analyzed 108 relapsed/refractory lymphoma patients who had high-dose treatments followed by autologous hematopoietic stem cell transplant between October 2012 and February 2017.

Results: At a median follow-up period of 16 months, the estimated 2-year progression-free survival rates for the TECAM and BEAM groups were 55.

In the era of tyrosine kinase inhibitors, resistance still constitutes a problem in chronic myeloid leukemia (CML) patients; thus, new pathway-specific inhibitors like miRNAs have become important in the treatment of refractory patients. There are no satisfying data regarding the miRNAs and anti-miRNA treatment targeting STAT5A and 5B. In this study, we first researched the effect of dasatinib on apoptosis in the CML cell line K562.

Haemophilia has been associated with low bone mineral density (BMD) probably due to some predisposing factors. The aim of this study was to evaluate the relationship between BMD and potential clinical predictors in adult haemophilic patients. Fortynine patients with moderate and severe haemophilia were enrolled.

Article Synopsis
  • Researchers looked for reasons why some adults with solid tumors had trouble collecting stem cells for their treatment.
  • They studied 49 patients over several years, finding that most had successful mobilization but some did not.
  • The only major risk factor they found for poor mobilization was having organ metastasis, suggesting more research is needed.

Background/aim: Invasive fungal infection (IFI) causes morbidity and mortality among patients with hematological malignancies. We evaluated the incidence and treatment characteristics of IFIs between October 2012 and December 2013. Materials and methods: Patients who received chemotherapy or stem cell transplantation were retrospectively evaluated.
