Little is known about the central nervous system (CNS) risk in high-grade B-cell lymphoma, not otherwise specified (HGBL, NOS). Hence, we sought to describe the rates of baseline CNS involvement, risk of CNS recurrence after primary therapy, and management strategies in HGBL, NOS. In this multicenter retrospective study, we included 160 adults with newly diagnosed HGBL, NOS treated between 2016 and 2021 at 20 US institutions. Eleven patients (7%) had baseline CNS involvement at diagnosis (leptomeningeal=6, parenchymal=4, and both=1)...

Iron overload and its complications are recognized to be morbid and fatal in patients with congenital hemolytic anemias. In patients with iron overload caused by congenital hemolytic anemias, there has been no study evaluating the dose-response relationship between serum markers of iron overload and long-term health complications. Filling this critical gap was the aim of the present study. We evaluated outcomes in a 5-hospital observational cohort study of adults with congenital hemolytic anemias diagnosed with iron overload over a 40-year period, and assessed associations between depth and duration of iron overload, and clinical complications including diabetes, heart disease, malignancy, bone density disorders, and death...

Autoimmune hemolytic anemia (AIHA) is a rare and sometimes life-threatening disease. Infections are frequent and often severe during the course of AIHA. Rituximab is commonly used to treat patients with AIHA. This study aimed to assess the risk of hospitalization with infection after rituximab in patients with primary AIHA. We selected all adult patients newly diagnosed for primary AIHA and treated with rituximab between 2012 and 2018 in the French National Health Database. Patients were considered exposed to rituximab within 6 months after the first infusion...

Through the use of genetic sequencing, molecular variants driving autoimmunity are increasingly identified in patients with chronic and refractory immune cytopenias. With the goal of discovering genetic variants that predispose to pediatric immune thrombocytopenia (ITP) or increase risk for chronic disease, we conducted a genome-wide association study in a large multi-institutional cohort of pediatric patients with ITP. Five-hundred ninety-one patients were genotyped using an Illumina Global Screening Array (GSA) BeadChip...

This multicenter study sponsored by GETH-TC aimed to investigate the incidence and predictors of early (within the first 100 days) and late cardiac events (CE) (ECE and LCE) following allo-HCT in AML patients treated with anthracyclines, focusing on exploring the impact of PTCY on cardiac complications and the impact of CE on overall survival (OS) and non-relapse mortality (NRM). 1020 AML patients were included. PTCY was given to 450 (44.1%) adults. Overall, 94 (9.2) patients experienced CE and being arrythmias, pericardial complications, and heart failure the most prevalent ones...

In allogeneic hematopoietic stem cell transplantation (alloSCT), alloreactive donor T cells mediate the graft-versus-leukemia (GVL) effect but also attack nonhematopoietic tissues causing graft-versus-host disease (GVHD). Reducing alloreactive T cell trafficking to GVHD target tissues while allowing their access to bone marrow (BM) and spleen, major sites of malignant hematopoiesis, is a rational strategy for reducing the GVHD risk when using alloreactive T cells as a therapeutic. Here we show that effector T cell (Teff) entry into BM and spleen in unmanipulated mice and in mice transplanted without alloreactive T cells is augmented by pertussis toxin-sensitive (PTX) chemokine receptor signaling...

Since 2005 there has been steady decline in chronic graft-versus-host disease (cGVHD) at Fred Hutchinson Cancer Center (FHCC). To better understand this phenomenon, we studied the risk of cGVHD requiring systemic immunosuppression (cGVHD-IS) as a function of hematopoietic cell transplantation (HCT)-date in 3066 survivors from 2005 through 2019. Cox regression models were fit to assess associations of HCT-date (as a continuous linear variable) with cause-specific hazards of cGVHD, using unadjusted and adjusted models...

Consolidation strategies for primary central nervous system lymphoma (PCNSL) after induction chemoimmunotherapy include whole-brain radiotherapy (≤24Gy reduced-dose [RD], >24Gy standard-dose [SD] WBRT) and cytarabine, non-myeloablative chemotherapy (NMC), or autologous hematopoietic cell transplantation (AHCT); however, comparative outcomes are lacking. PCNSL outcomes from 1983-2020 were stratified by decade and MSKCC recursive partitioning analysis (RPA) class. Clinicodemographic associations with consolidation were analyzed by multinomial logistic regression...

BMT CTN 1506 was a phase III randomized trial comparing gilteritinib versus placebo after allogeneic HCT for FLT3-ITD-positive AML. The primary analysis comparing relapse-free survival (RFS) was not statistically significant, however, patients with detectable FLT3-ITD MRD peri-HCT had significantly longer RFS with gilteritinib. The aim of this analysis is to describe the effect of post-HCT gilteritinib versus placebo on health-related quality of life (HRQOL). HRQOL was measured using the Functional Assessment of Cancer Therapy (FACT)-BMT, FACT-Leukemia (-Leu), and EQ-5D-5L at post-HCT randomization, day 29, month 3, 6, 12, 18, 24, and/or end of therapy...

HLA-matched sibling donors (MSDs) are preferred for hematopoietic cell transplantation (HCT). However, the use of alternative donors, especially haploidentical, is increasing, as is our understanding of the impact of HLA factors such as B-leader and DRB1-matching on its outcomes. Yet, data comparing these donor types, particularly considering these HLA factors, is lacking. Herein, we compared haploidentical-HCT (n=1052) to MSD-HCT (n=400), both with posttransplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis...

Despite numerous efforts to raise awareness, many hemophilia carriers and female persons with hemophilia (PWHs) remain undiagnosed. Between May 2021 and April 2023, we identified potential and obligate carriers of hemophilia A (HA) and B (HB) by updating pedigrees of all PWHs followed at the Cliniques universitaires Saint-Luc, Brussels. Retrospective data on previously screened females were collected, including bleeding history, coagulation factor levels, and testing for the proband's pathogenic variant. Additionally, a proactive approach involved sending 125 invitation letters to unscreened or incompletely screened individuals, through related PWHs...

Warfarin dose requirements are highly variable due to clinical and genetic factors. While genetic variants influencing warfarin dose have been identified in European and East Asian populations, more work is needed to identify African-specific genetic variants to help optimize warfarin dosing. We performed genome-wide association studies (GWAS) in four African cohorts from Uganda, South Africa, and Zimbabwe, totalling 989 warfarin-treated participants who reached stable dose and had international normalized ratios within therapeutic ranges...

Tafasitamab plus lenalidomide (TAFA-LEN) treatment relevance pre- or post-anti-CD19 CAR T-cell is currently debated. We analyzed large B-cell lymphoma patients in the DESCAR-T registry treated with axi-cel or tisa-cel in ≥3rd line (L3+) and TAFA-LEN before (n=15, 'TL-pre-CAR-T' set) or directly after (n=52, 'TL-post-CAR-T' set) CAR T-cell. We compared TAFA-LEN v. other treatments using inverse probability weighting in the TL-post-CAR-T set. In the TL-post-CAR-T' set, the median follow-up duration (mFUD) was 7 months, and the median progression-free survival, overall survival and duration of response since the 1st treatment for progression (mPFS2/mOS2/mDOR2) were 3, 4...

Bronchiolitis obliterans syndrome (BOS) after hematopoietic cell transplantation (HCT) is associated with substantial morbidity and mortality. Quantitative CT (qCT) can help diagnose advanced BOS meeting National Institutes of Health (NIH) criteria (NIH-BOS) but has not been used to diagnose early, often asymptomatic BOS (early BOS), limiting the potential for early intervention and improved outcomes. Using Pulmonary Function Tests (PFT) to define NIH-BOS, early BOS, and mixed BOS (NIH-BOS with restrictive lung disease) in patients from two large cancer centers, we applied qCT to identify early BOS and distinguish between types of BOS...
