As a hematopathologist, I work on diagnostics of all types of hematological malignancies using a comprehensive panel of different techniques. Moreover, my main research interest involves Hodgkin lymphoma, with a strong focus on interactions between tumor cells and the microenvironment. In addition, I also have a long standing interest in genetic susceptibility. My areas of expertise are: immunology, tumor cell biology, genetic association studies and molecular diagnostics in pathology. I actively participate in international (EORTC) and national (HOVON) clinical trials.

Iron deficiency, anemia, and patient-reported outcomes in kidney transplant recipients
Published in: American Journal of Transplantation
Access to document

document
Kidney transplant recipients (KTRs) experience more fatigue, anxiety, and depressive symptoms and lower concentration and health-related quality of life (HRQoL) compared with the general population. Anemia is a potential cause that is well-recognized and treated. Iron deficiency, however, is often unrecognized, despite its potential detrimental effects related to and unrelated to anemia. We investigated the interplay of anemia, iron deficiency, and patient-reported outcomes in 814 outpatient KTRs (62% male, age 56 ± 13 years) enrolled in the TransplantLines Biobank and Cohort Study (Groningen, The Netherlands). In total, 28%...

Treatment strategies and outcome in relapsed peripheral T-cell lymphoma: results from the Netherlands Cancer Registry
Published in: Blood Advances
Access to document

document
Optimal treatment in patients with refractory or relapsed peripheral T-cell lymphomas (R/R T-NHLs) is unknown. In this population-based study, outcomes in R/R peripheral T-cell lymphoma not otherwise specified (PTCL NOS), angioimmunoblastic T-cell lymphoma (AITL), and anaplastic lymphoma kinase-positive (ALK+) and ALK-negative (ALK-) anaplastic large cell lymphoma (ALCL) were evaluated. Patients with PTCL NOS, AITL, ALK+ ALCL, and ALK- ALCL (≥18 years) diagnosed in 2014 to 2019 were identified using the Netherlands Cancer Registry. End points were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). The...

Core regions in immunoglobulin heavy chain enhancers essential for survival of non-Hodgkin lymphoma cells are identified by a CRISPR interference screen
Published in: Haematologica
Access to document

document
Chromosomal translocations in non-Hodgkin lymphoma (NHL) result in activation of oncogenes by placing them under the regulation of immunoglobulin heavy chain (IGH) super-enhancers. Aberrant expression of translocated oncogenes induced by enhancer activity can contribute to lymphomagenesis. The role of the IGH enhancers in normal B-cell development is well established, but knowledge regarding the precise mechanisms of their involvement in control of the translocated oncogenes is limited. The goal of this project was to define the critical regions in the IGH regulatory elements and identify enhancer RNAs (eRNA). We...

Memory B-cell derived donor-specific antibodies do not predict outcome in sensitized kidney transplant recipients: a retrospective single-center study
Published in: Frontiers in Immunology
Access to document
10.3389/fimmu.2024.1360627
document
BACKGROUND: Repeated exposure to sensitizing events can activate HLA-specific memory B cells, leading to the production of donor-specific memory B cell antibodies (DSAm) that pose a risk for antibody-mediated rejection (ABMR) in kidney transplant recipients (KTRs). This single-center retrospective study aimed to identify DSAm and assess their association with outcomes in a cohort of KTRs with pretransplant serum donor-specific antibodies (DSA). METHODS: We polyclonally activated pretransplant peripheral blood mononuclear cells (PBMCs) from 60 KTRs in vitro, isolated and quantified IgG from the culture supernatant using ELISA, and analyzed...

Detection of circulating tumor DNA in plasma of patients with primary CNS lymphoma by digital droplet PCR
Published in: BMC Cancer
Access to document
10.1186/s12885-024-12191-z
document
BACKGROUND: Primary central nervous system lymphoma (PCNSL) are rare mature B-cell lymphoproliferative diseases characterized by a high incidence of MYD88 L265P and CD79B Y196 hotspot mutations. Diagnosis of PCNSL can be challenging. The aim of the study was to analyze the detection rate of the MYD88 L265P and CD79B Y196 mutation in cell free DNA (cfDNA) in plasma of patients with PCNSL. METHODS: We analyzed by digital droplet PCR (ddPCR) to determine presence of the MYD88 L265P and CD79B Y196 hotspot mutations in cfDNA isolated from plasma of...
