Clinical characteristics and survival outcomes of patients with primary central nervous system lymphoma treated with high-dose methotrexate-based polychemotherapy and consolidation therapies.

Given the rarity of primary central nervous system lymphoma (PCNSL), evaluations of different high-dose methotrexate-(HD-MTX)-based treatment regimens is sparse. This retrospective, multicenter study evaluates clinical characteristics and outcomes (progression-free, overall and disease-specific survival) after five HD-MTX-based polychemotherapeutic regimens and two consolidation therapies. 346 patients with histologically confirmed PCNSL, treated with ≥ 1 cycle HD-MTX-based strategies (≥3g/m/cycle) were included.

Impact of comorbidity on health-related quality of life in newly diagnosed patients with lymphoma or multiple myeloma: results from the PROFILES-registry.

With the increasing prevalence of comorbidity in an ageing population, it is crucial to better understand the impact of comorbidity on health-related quality of life (HRQoL) after lymphoma or multiple myeloma (MM) diagnosis. We included 261 newly diagnosed patients (67% response rate) diagnosed with lymphoma or MM between October 2020 and March 2023 in a longitudinal survey. The European Organisation for Research and Treatment of Cancer (EORTC) questionnaires were used to measure generic and disease-specific HRQoL.

Doxorubicin Exposure and Breast Cancer Risk in Survivors of Adolescent and Adult Hodgkin Lymphoma.

Purpose: Female Hodgkin lymphoma (HL) survivors treated with chest radiotherapy (RT) at a young age have a strongly increased risk of breast cancer (BC). Studies in childhood cancer survivors have shown that doxorubicin exposure may also increase BC risk. Although doxorubicin is the cornerstone of HL chemotherapy, the association between doxorubicin and BC risk has not been examined in HL survivors treated at adult ages.

Frequent mutated B2M, EZH2, IRF8, and TNFRSF14 in primary bone diffuse large B-cell lymphoma reflect a GCB phenotype.

Primary bone diffuse large B-cell lymphoma (PB-DLBCL) is a rare extranodal lymphoma subtype. This retrospective study elucidates the currently unknown genetic background of a large clinically well-annotated cohort of DLBCL with osseous localizations (O-DLBCL), including PB-DLBCL. A total of 103 patients with O-DLBCL were included and compared with 63 (extra)nodal non-osseous (NO)-DLBCLs with germinal center B-cell phenotype (NO-DLBCL-GCB).

Performance of idarucizumab as antidote of dabigatran in daily clinical practice.

Aims: Because practice-based data on the usage of idarucizumab for urgent dabigatran reversal is unavailable, we evaluated the appropriateness of idarucizumab usage, its haemostatic effectiveness and clinical outcomes.

Methods And Results: An observational cohort study was performed including consecutive patients who were treated with idarucizumab between 2016 and 2018. Appropriate usage was assessed with predefined criteria.

Prospective evaluation of sequential treatment of sclerotic chronic graft versus host disease with rituximab and nilotinib.

Sclerotic chronic graft vs. host disease (cGVHD) still has a large impact on morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). We performed the first prospective study to test whether sequential therapy of the anti-CD20 antibody rituximab followed by 6 months treatment with tyrosine kinase inhibitor nilotinib is a favorable treatment strategy for patients with sclerotic cGVHD.

Sufficient Immunosuppression with Thymoglobulin Is Essential for a Successful Haplo-Myeloid Bridge in Haploidentical-Cord Blood Transplantation.

In haploidentical (haplo)-cord blood (CB) transplantations, early haplo donor engraftment serves as a myeloid bridge to sustainable CB engraftment and is associated with early neutrophil recovery. The conditioning regimens as published for haplo-cord protocols usually contain serotherapy, such as rabbit antithymocyte globulin (ATG) (Thymoglobulin, Genzyme, Cambridge, MA). However, reducing or omitting serotherapy is an important strategy to improve early immune reconstitution after transplantation.

Evaluation of Dutch guideline for just-in-time addition of plerixafor to stem cell mobilization in patients who fail with granulocyte-colony-stimulating factor.

Background: Plerixafor in combination with granulocyte-colony-stimulating factor (G-CSF) is approved for the use of stem cell collection in patients who fail to mobilize on G-CSF. In 2009 the Stem Cell Working Party of the Dutch-Belgian Cooperative Trial group for Hematology Oncology (HOVON) composed a guideline for the use of plerixafor. According to this guideline it is recommended to add plerixafor to G-CSF in patients with circulating CD34+ cell counts of fewer than 20 × 10(6) /L on 2 consecutive days accompanied by increasing white blood cells.

Refinement of the definition of permissible HLA-DPB1 mismatches with predicted indirectly recognizable HLA-DPB1 epitopes.

Hematopoietic stem cell transplantation with HLA-DPB1-mismatched donors leads to an increased risk of acute graft-versus-host disease (GVHD). Studies have indicated a prognostic value for classifying HLA-DPB1 mismatches based on T cell-epitope (TCE) groups. The aim of this study was to determine the contribution of indirect recognition of HLA-DP-derived epitopes, as determined with the Predicted Indirectly ReCognizable HLA Epitopes (PIRCHE) method.

Indirectly Recognized HLA-C Mismatches and Their Potential Role in Transplant Outcome.

HLA-C mismatches are clearly associated to alloreactivity after hematopoietic stem-cell transplantation; in a number of large cohorts, HLA-C mismatches are correlated to an increased risk of acute graft-versus-host disease (GVHD) or even impaired survival. While for HLA-A and -B, both antigenic as well as allelic mismatches are associated with an increased risk of acute GVHD, such an increased risk is only observed for antigenic HLA-C mismatches and not for allelic mismatches. These observations raise the question what sets HLA-C apart from HLA-A and -B.

Absence of intraocular infections after hematopoietic stem cell transplantation at a single center: the experience with current preventive regimens.

Purpose: To investigate the prevalence of intraocular infections after allogeneic stem cell transplantation (allo-SCT).

Methods: The study design was a single institutional retrospective noncomparative cohort of 135 consecutive patients in 2006 and 2007 who underwent allo-SCT for hematological malignancy. The primary outcome was the development of intraocular infections after allo-SCT and secondary outcome consisted of development of other ocular disorders during follow-up.

Impact of ocular graft-versus-host disease on visual quality of life in patients after allogeneic stem cell transplantation: questionnaire study.

Purpose: To determine the influence of ocular complications on quality of life (QoL) 3 years after allogeneic stem cell transplantation (allo-SCT).

Methods: All 54 adult patients that underwent and survived allo-SCT in 2006/2007 in our centre received two questionnaires (VFQ-25: visual function questionnaire-25 and OSDI: ocular surface disease index). In addition, the following data were included: gender, age, underlying disease, presence of chronic and/or ocular graft-versus-host disease (GVHD), number of visits to an ophthalmologist, manifestations of dry eye disease, the duration of follow-up and treatment for ocular GVHD.

Platelet-mediated proteolytic down regulation of the anticoagulant activity of protein S in individuals with haematological malignancies.

The natural anticoagulant protein S contains a so-called thrombin- sensitive region (TSR), which is susceptible to proteolytic cleavage. We have previously shown that a platelet-associated protease is able to cleave protein S under physiological plasma conditions in vitro . The aim of the present study was to investigate the relation between platelet-associated protein S cleaving activity and in vivo protein S cleavage, and to evaluate the impact of in vivo protein S cleavage on its anticoagulant activity.

The immunological phenotype of rituximab-sensitive chronic graft-versus-host disease: a phase II study.

Chronic graft-versus-host disease is the major long-term complication after allogeneic stem cell transplantation with a suboptimal response rate to current treatments. Therefore, clinical efficacy and changes in lymphocyte subsets before and after rituximab treatment were evaluated in a prospective phase II study in patients with steroid-refractory chronic graft-versus-host disease. Overall response rate was 61%.

Current insights into ocular graft-versus-host disease.

Purpose Of Review: To update our knowledge on hematopoietic stem cell transplantation (SCT) and graft-versus-host disease (GVHD) and summarize the current treatment options for ocular GVHD.

Recent Findings: Allogeneic (allo)-SCT represents a treatment option for a number of hematological malignancies and bone marrow disorders; the indications for this procedure are still increasing. Ocular GVHD develops in 40-60% of patients after allo-SCT, can cause severe ocular surface disease and has a negative impact on quality of life.

Use of sidestream dark-field (SDF) imaging for assessing the effects of high-dose melphalan and autologous stem cell transplantation on oral mucosal microcirculation in myeloma patients.

Background: Oral mucositis (OM) is a common toxic side effect among patients receiving high-dose chemotherapy (CT) with autologous stem cell transplantation (ASCT) for hematologic malignancies. The aim of this study was to investigate changes in submucosal microcirculation in myeloma patients receiving high-dose CT with ASCT by assessing capillary density and microvascular structural integrity.

Methods: Ten consecutive patients with multiple myeloma who underwent first-time CT treatment with high-dose melphalan (200 mg/m(2)) and ASCT were included in this study.

Mortality in systemic sclerosis: an international meta-analysis of individual patient data.

Purpose: Studies on mortality associated with systemic sclerosis have been limited by small sample sizes. We aimed to obtain large-scale evidence on survival outcomes and predictors for this disease.

Methods: We performed a meta-analysis of individual patient data from cohorts recruited from seven medical centers in the United States, Europe, and Japan, using standardized definitions for disease subtype and organ system involvement.
