Background: The development of newer agents, including anti-CD38 monoclonal antibodies (mAbs), has significantly improved overall survival (OS) in patients with relapsed or refractory multiple myeloma (RRMM). However, the treatment of older patients with RRMM who are transplant-ineligible remains challenging.
Methods: We retrospectively evaluated OS in 78 transplant-ineligible patients with RRMM who were aged ≥ 65 years and treated at our institution between February 2012 and November 2023.
A 62-year-old woman was diagnosed as a hemophilia A carrier (factor VIII activity 35%) on preoperative examination of an ovarian tumor. A total of 35,600 units of recombinant factor VIII products was administered perioperatively. On postoperative day 95, a subcutaneous hematoma formed and immunosuppressive therapy with prednisolone was started based on an APTT of 66 seconds, factor VIII (FVIII) activity of 3%, and FVIII inhibitor of 1 BU/ml.

A single-dose pegylated G-CSF (PEG-G-CSF) has been used for the treatment of chemotherapy-induced neutropenia. We retrospectively examined 15 patients (median age 61, range 33-75 years) treated with DA-EPOCH-R.

A 22-year-old female was diagnosed with common-B-cell-ALL positive for CD10, CD19, CD22, CD79a, CD34, HLA-DR, and TdT in January 2017, and achieved complete remission (CR) with induction therapy, followed by consolidation therapy and maintenance therapy. In March 2020, 6 months after the completion of maintenance therapy, she relapsed.

To investigate the possibility of therapeutic application of genome editing, we generated induced pluripotent stem cells (iPSCs) from a FV-deficient patient and repaired the mutation of factor V gene (F5) using a clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9).
Methods: The patient's peripheral blood mononuclear cells were reprogrammed for iPSCs.
The clustered regulatory interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) system is an efficient genome-editing tool that holds potential for gene therapy. Here, we report an application of this system for gene repair in hemophilia B (HB) using induced pluripotent stem cells (iPSCs). We prepared targeting plasmids with homology arms containing corrected sequences to repair an in-frame deletion in exon 2 of the factor IX (F9) gene and transfected patient-derived iPSCs with the Cas9 nuclease and a guide RNA expression vector.

We report a case of ATLL that was treated with sequential mogamulizumab (MOG) and lenalidomide (LEN) for early relapse after allo-HSCT. A 73-year-old Japanese male with acute-type ATLL underwent haploidentical-HSCT with post-transplant cyclophosphamide.

We compared the outcomes in 35 patients who received mycophenolate mofetil plus cyclosporine (MMF/CSP, n = 17) or MMF plus tacrolimus (MMF/TAC, n = 18) for graft-versus-host disease (GVHD) prophylaxis after RIC-UCBT. Cumulative incidence of neutrophil engraftment was 94 and 89 % in MMF/CSP and MMF/TAC groups, respectively (p = 0.

However, whether the presence of the JAK2 V617F mutation affects thrombotic risk is currently unknown, although some reports have suggested a variable association with thrombosis. Therefore, we investigated the association between JAK2 V617F and various complications, including thrombosis, in Japanese patients with MPNs.

FGFR1 encodes a transmembrane receptor tyrosine kinase. The resultant fusion proteins are constitutively active tyrosine kinases that drive the proliferation of hematopoietic cells, whose uncontrolled growth can present as a myeloproliferative neoplasm.

Clonal B cells with light chain restriction (kappa:lambda ratio >3:1 or <1:2) were analyzed for CD5 expression and the presence of monoclonal immunoglobulin heavy-chain (IGH) gene rearrangements and the t(14;18) chromosomal translocation. Clonal B cells were detected in 7 cases with HCV (2.
