Background: A combination of busulfan (Bu) and cyclophosphamide (Cy) has been used as a standard myeloablative regimen for allogeneic hematopoietic stem cell transplantation (HSCT). Recent studies postulate that fludarabine (Flu) is a less toxic substitute for Cy.
Methods: Forty-two patients who were diagnosed with acute leukemia or myelodysplastic syndrome and received BuFlu (n=17) or BuCy (n=25) from August, 1999 to July, 2009 at Dong-A University Medical Center were retrospectively analyzed.
Results: The median follow-up duration was 39.75 months. The BuFlu group showed a lower incidence of mucositis (P=0.005), but there was no significant intergroup difference in the time of engraftment, nausea/vomiting, acute/chronic graft-versus-host disease, hepatic veno-occlusive disease, or hemorrhagic cystitis. Moreover, the 2 groups showed no significant difference in the cumulative risk of relapse, event-free survival, or overall survival.
Conclusion: BuFlu administration can be employed as a preparative regimen for allogeneic HSCT and shows efficacy and transplant-adverse effects comparable to those of BuCy. However, randomized prospective studies in more patients are warranted.

JAGN1 (Jagunal-homolog1) is a ER-resident transmembrane protein which is part of the early secretory pathway and granulocyte colony-stimulating factor receptor mediated signaling. Autosomal recessively inherited variants in the JAGN1 gene lead to congenital neutropenia, early-onset bacterial infections, aphthosis and skin abscesses due to aberrant differentiation and maturation of neutrophils. In addition, bone metabolism disorders and a syndromic phenotype, including facial features, short stature and neurodevelopmental delay, have been reported in affected patients.

Article Synopsis
- Despite improvements in targeted therapy for Acute Myeloid Leukemia (AML), the prognosis remains poor, particularly for patients with relapsed or refractory disease.
- Allogeneic hematopoietic stem cell transplantation (alloSCT) is the main curative option for high-risk patients, but the best conditioning approach is still uncertain for those who are chemotherapy-refractory.
- A study on seven AML patients who received CXCR4-directed endoradiotherapy (ERT) combined with total body irradiation and chemotherapy prior to alloSCT showed promising outcomes, with 6 out of 7 patients achieving response and successful engraftment, offering insights into a potentially effective treatment strategy for advanced cases.

Introduction: Posttransplant cyclophosphamide (PTCy) has revolutionized the landscape of human leukocyte antigen (HLA)-haploidentical hematopoietic cell transplantation (haplo-HCT), providing a pivotal therapeutic option for patients with hematological malignancies who lack an HLA-matched donor.
Methods: In this retrospective analysis involving 54 adult patients undergoing PTCy-based haplo-HCT, we evaluated the impact of inhibitory killer immunoglobulin-like receptor (KIR)/HLA mismatch, alongside patient, donor, and transplant factors, on clinical outcomes within a homogeneous cohort characterized by a myeloablative conditioning regimen and bone marrow graft.
Results: With a median follow-up of 73.

Background: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is recommended for patients with KMT2A-rearranged (KMT2A-r) leukemia whereas relapse remains high. We aimed to determine whether intensified conditioning containing decitabine (Dec) could reduce relapse compared with standard myeloablative conditioning in adult patients with KMT2A-r leukemia.
Methods: We performed a multicenter retrospective study at seven institutions in China.

Background: The management of high-risk acute myeloid leukaemia (AML) remains challenging, highlighting the need for innovative conditioning strategies beyond current regimens.
Methods: In the present single-arm study, a FACT regimen comprised of low-dose total body irradiation (TBI) with fludarabine, cytarabine and cyclophosphamide was employed to treat cytogenetically high-risk AML patients exhibiting pre-transplant active disease. This clinical trial is registered in the Chinese Clinical Trial Registry with the registration number ChiCTR2000035111.
