ABSTRACT

The IFM/DFCI group reported that VRD induction followed by up-front autologous peripheral blood stem cell transplantation (ASCT) and maintenance therapy led to median PFS of 50 months, which established up-front ASCT as the standard of care even in the era of novel agents. We conducted a retrospective analysis on outcomes of patients who received triplet induction therapy followed by up-front ASCT at our institution. A total of 124 patients received ASCT between November 2016 and December 2021 at Japanese Red Cross Medical Center. Patient characteristics, treatment response before and after ASCT, and PFS and OS were retrospectively analyzed. VRD-based induction therapy was used for 94%. Among 118 evaluable patients, 116 (98%) received either consolidation and/or maintenance therapy. Best responses were ≥CR 77% and ≥VGPR 94%, respectively. Sixty-eight out of 104 patients achieved MRD-negativity by multiparameter FCM (<10-5). Five-year estimated PFS and OS were 54.7% and 80.2%, respectively. Age ≥65, high-risk cytogenetic abnormalities, and

ABSTRACT

A 28-year-old female was diagnosed with acute myeloid leukemia (AML) due to t (8;21) (q22;q22.1); RUNX1-RUNX1T1 at 21 weeks of gestation. Because no adverse prognostic genetic mutations were discovered, we decided to continue the pregnancy without chemotherapy for as long as possible. After careful monitoring with blood tests every two weeks, the disease did not progress until full-term, and a cesarean section was performed at 39 weeks of gestation. About two months after delivery, blasts in the peripheral blood increased to 46.5%, and myeloblasts in the bone marrow increased to 21.2%. The patient received idarubicin and cytarabine induction therapy, followed by three cycles of high-dose cytarabine consolidation therapy, and complete remission was maintained. Here we report a rare case who could avoid chemotherapy until full-term labor without progression of AML.

ABSTRACT

Isatuximab and daratumumab are anti-CD38 monoclonal antibodies used to treat refractory multiple myeloma. Isatuximab is often used after unsuccessful daratumumab treatment; however, the clinical benefits of receiving isatuximab after daratumumab treatment have not been fully evaluated. Therefore, this retrospective cohort study assessed the clinical outcomes of 39 patients with multiple myeloma who were administered isatuximab after daratumumab. The median follow-up period was 8.7 months (range 0.1-25.0 months). The overall response rate was 46.2% (18 patients). The 1-year overall survival was 53.9%, with a median progression-free survival of 5.6 months. The median progression-free survival in patients with high and normal lactate dehydrogenase levels was 4.5 and 9.6 months, respectively (P = 0.004). The median progression-free survival in patients with and without triple-class refractory disease was 5.1 months and not reached, respectively (P = 0.001). The median overall survival in patients with high and normal lactate dehydrogenase levels was not reached and 9.3 months, respectively (P = 0.001). The median overall survival in patients with and without triple-class refractory disease was 9.9 months and not reached, respectively (P = 0.038). Our findings provide insight into the optimal use and timing of anti-CD38 antibody therapy.

ABSTRACT

Adult T-cell leukemia/lymphoma (ATLL) is a human T-cell leukemia virus type 1-inducing unevenly-distributed T-cell malignancy, which is often complicated by opportunistic infections. Here, we discuss the case of a 75-year-old woman presenting with Pneumocystis pneumonia (PCP) who was subsequently diagnosed with ATLL in Tokyo, a non-endemic area of ATLL. In addition to the elevated soluble interleukin-2 receptor and the detection of flower cells in the screening blood test, the high-resolution computed tomography findings, atypical of PCP, were clues to the diagnosis of ATLL. ATLL should be considered as an underlying disease when patients present with PCP, even in non-endemic areas.

ABSTRACT

Unrelated bone marrow transplantation (uBMT) is performed to treat blood disorders, and it uses bone marrow from an unrelated donor as the transplant source. Although the importance of HLA matching in uBMT has been established, that of other genetic factors, such as single-nucleotide polymorphisms (SNPs), remains unclear. The application of immunoinhibitory receptors as anticancer drugs has recently been attracting attention. This prompted us to examine the importance of immunoinhibitory receptor SNPs in uBMT. We retrospectively genotyped five single-nucleotide polymorphisms (SNPs) in the immune checkpoint genes, BTLA, PD-1, LAG3, and CTLA4, and two SNPs in the methylase genes, DNMT1 and EZH2, in 999 uBMT donor-recipient pairs coordinated through the Japan Marrow Donor Program matched at least at HLA-A, -B, and -DRB1. No correlations were observed between these SNPs and post-uBMT outcomes (p > 0.005). This result questions the usefulness of these immune checkpoint gene polymorphisms for predicting post-BMT outcomes. However, the recipient EZH2 histone methyltransferase gene SNP, which encodes the D185H substitution, exhibited a low p-value in regression analysis of grade 2-4 acute graft-versus-host disease (p = 0.010). Due to a low minor allele frequency, this SNP warrants further investigation in a larger-scale study.
