Risk Stratification Using DIPSS and Splenomegaly in Myelofibrosis Treated with Pre-Transplant JAK inhibitors.

The Dynamic International Prognostic Scoring System for primary myelofibrosis (DIPSS) has been reported to predict transplant outcomes in myelofibrosis (MF) patients. Recently, the pre-transplant use of JAK inhibitors has become common in clinical practice, but it is unclear whether DIPSS is also useful for predicting transplant outcomes for these patients. In this study, we compared the prognostic impact of DIPSS between MF patients with and without pre-transplant Ruxolitinib therapy.

Clinical significance of C-reactive protein/platelet ratio from diagnosis to allogeneic hematopoietic stem cell transplantation in acute myeloid leukemia.

Previous studies have shown that C-reactive protein/platelet ratio (CPR) before allogeneic hematopoietic stem cell transplantation (HSCT) is a predictor of survival in patients with hematological malignancies. This multicenter retrospective study aimed to evaluate the clinical significance of CPR from diagnosis to HSCT in patients with acute myeloid leukemia (AML) who underwent HSCT. This cohort included patients with AML who underwent their first HSCT between 2016 and 2021.

Comparison of clinical outcomes between preemptive and maintenance therapy after allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia.

This study aimed to compare the efficacy and safety of preemptive and maintenance therapies as post-transplant therapy for acute myeloid leukemia (AML). Patients with AML who underwent allogeneic stem cell transplantation and received post-transplant therapy were eligible. Preemptive therapy was initiated if elevated Wilms' tumor-1 mRNA was detected in the peripheral blood.

Improved Transplant Outcomes With Alternative Donors in Myelofibrosis: A 20-Year Japanese Registry Analysis of Donor Sources and the Impact of Ruxolitinib.

This study of 308 myelofibrosis patients shows that in recent years (2013-2019), alternative donors (mismatched unrelated donors and cord blood) achieved survival rates comparable to HLA-matched donors-a significant improvement compared to earlier years (2000-2012) when outcomes differed substantially. Ruxolitinib showed significant benefits in older patients (≥ 57), particularly with mismatched unrelated donors. Cord blood transplantation outcomes improved with MMF-based GVHD prophylaxis.

Preconditioning intervention prior to allogeneic hematopoietic stem cell transplantation in patients with high-risk acute myeloid leukemia.

The outcomes of patients with high-risk acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (HCT) remain poor despite many attempts at developing therapeutic strategies. Preconditioning interventions (PCIs) have been applied to patients with high-risk AML to reduce the disease burden before starting the conditioning regimen. A single-center retrospective study was performed to evaluate the safety and efficacy of PCI in allograft patients with high-risk AML.

[Successful treatment with venetoclax and azacitidine for extramedullary relapse of acute myeloid leukemia after cord blood transplantation].

A 33-year-old man was diagnosed with acute myeloid leukemia (AML). He was treated with daunorubicin and cytarabine and achieved complete remission. He underwent consolidation therapy with three cycles of venetoclax and azacitidine (VEN+AZA).

Comparing de novo chronic myeloid leukemia in blastic phase with Philadelphia chromosome-positive acute lymphoblastic leukemia after allogeneic hematopoietic cell transplantation.

Background: De novo chronic myeloid leukemia in blastic phase (CML-BP) showing lymphoid immunophenotype mimics Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph-positive ALL). Although upfront allogeneic hematopoietic cell transplantation (HCT) is considered in both diseases, it is not yet clear whether the transplant outcomes are also similar.

Methods: Using a registry database, the transplant outcomes between de novo CML-BP and Ph-positive ALL in negative-minimal residual disease (MRD), positive MRD, and nonremission cohorts were compared, respectively.

Impact of bone marrow nucleated cell subfractions on transplant outcomes in patients with acute lymphoblastic leukemia.

Objectives: Our previous study showed that a high pre-transplant nucleated cell count in the bone marrow is associated with increased non-relapse mortality (NRM) and decreased overall survival (OS) in patients with acute lymphoblastic leukemia (ALL) in remission. In this retrospective multicenter study, we aimed to examine the association between nucleated cell subfractions and transplant outcomes using the same patient cohort as our previous study.

Methods: This study included patients with ALL who underwent their first allogeneic hematopoietic stem cell transplantation (allo-HSCT) between 2010 and 2022.

Allogeneic stem cell transplant with TBI-based myeloablative conditioning in adolescents and young adults with Philadelphia chromosome-negative ALL treated with pediatric protocols.

To investigate the safety of total body irradiation-based myeloablative conditioning (TBI-MAC) in adolescent and young adult (AYA) Philadelphia chromosome (Ph)-negative acute lymphoblastic leukemia (ALL) patients treated with pediatric protocols, treatment outcomes of 106 AYA patients aged 16-39 years old undergoing allogeneic stem cell transplant (allo-SCT) with TBI-MAC in the first remission were compared according to chemotherapy types before transplant. Pediatric and adult protocols were used in 56 and 50 of the patients, respectively. The cumulative incidence (CI) of non-relapse mortality (NRM) and the overall survival (OS) rates were not significantly different between the pediatric-protocol and adult-protocol group (NRM: 4 % vs.

Survival impact of response within the first year in a multicenter prospective observational study of chronic GVHD in a Japanese cohort.

A prospective multicenter observational study of organ response was conducted in patients with chronic GVHD diagnosed by the NIH criteria. When response was assessed at 12 months (12 M) in 118 patients, 74.6% were classified as responders and 25.

Successful treatment of two cases with Philadelphia-chromosome positive acute lymphoblastic leukemia who relapsed after allogeneic stem cell transplantation and the treatments with novel immunotherapies and ponatinib.

The outcomes of relapsed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) resistant to new drugs such as tyrosine kinase inhibitors, inotuzumab ozogamicin (InO) and blinatumomab are dismal. We treated two cases of Ph+ALL resistant to these drugs that achieved long-term survival after treatment with chimeric antigen receptor (CAR)-T cell therapy or a second allogeneic hematopoietic stem cell transplantation (HCT) with a sequential conditioning regimen. Case 1: A 15-year-old boy was diagnosed with Ph+ALL.

Acute mixed-lineage leukemia treated with desensitization therapy prior to HLA-haploidentical transplantation with high donor-specific antibodies.

A 43-year-old woman was referred to our department for hematopoietic stem cell transplantation for acute myeloid leukemia, as she failed to achieve remission following induction therapy. Umbilical cord blood transplantation was initially planned; however, multiple anti-human leukocyte antigen (HLA) antibodies with a mean fluorescence intensity of over 10,000 were detected, and optimal umbilical cord blood could not be obtained. The plan was then switched to peripheral blood stem cell transplantation (PBSCT) from the patient's son, who had a 5/8 HLA haploidentical match.

Pretransplantation Inflammatory and Nutritional Status in Elderly Allogeneic Hematopoietic Stem Cell Transplantation: Prognostic Value of C-Reactive Protein-to-Albumin Ratio.

There are no clear criteria for selecting elderly patients with hematologic malignancies eligible for allogeneic hematopoietic stem cell transplantation (HSCT). This study aimed to evaluate inflammatory and nutritional status biomarkers as prognostic indicators of allogeneic HSCT in elderly patients. We compared the prognostic effects of 4 representative pretransplantation biomarkers: C-reactive protein-to-albumin ratio (CAR), Glasgow Prognostic Score (GPS), prognostic nutritional index (PNI), and albumin-to-globulin ratio (AGR).

Clinical factors for central nervous system progression and survival in primary vitreoretinal lymphoma.

Primary vitreoretinal lymphoma (PVRL) is a rare subtype of malignant lymphoma with a poor prognosis because of high frequency of central nervous system (CNS) progression. Identification of factors associated with CNS progression is essential to improve the prognosis of patients with PVRL. We conducted a retrospective study of 54 patients diagnosed with PVRL and treated at our hospital to identify factors associated with CNS progression and prognosis.

Prognostic significance of the CFA ratio for newly diagnosed acute myeloid leukemia: A multicenter retrospective study.

The CFA ratio, calculated using pretreatment C-reactive protein (CRP), fibrinogen, and albumin levels (CRP × fibrinogen/albumin), was previously reported to be a significant prognostic factor for acute myeloid leukemia (AML). This multicenter retrospective study evaluated the prognostic value of the CFA ratio in 328 adult patients with newly diagnosed AML from April 2000 to March 2018. The median age was 49.

Treatment strategy at the decision for allogeneic transplantation in patients with myelodysplastic syndrome in the era of azacitidine: A KSGCT prospective study.

The optimal bridge strategy at the decision for allogeneic hematopoietic stem cell transplantation (HSCT) in patients with myelodysplastic syndrome (MDS) is unclear. We performed a prospective observational study in which 110 patients with MDS who were decided to undergo HSCT were enrolled. Among these 110 patients, 77 patients were enrolled in this study within 1 month from the decision for HSCT.

Bridging to transplant and post-transplant maintenance therapy with FLT3 inhibitors in patients with relapsed or refractory FLT3 mutated acute myeloid leukemia.

Objectives And Methods: This single-center retrospective study was performed to evaluate the safety and efficacy of FMS-like tyrosine kinase 3 (FLT3) inhibitors before and after allogeneic hematopoietic cell transplantation (HCT) in relapsed/refractory patients with FLT3-mutation positive acute myeloid leukemia (AML).

Results: Ten patients who met the eligibility criteria were included. Eight of them achieved hematological remission at HCT, within a median span of 79 days (range: 43-197).
