I work as a hematologist and my main focus is on patients with aggressive B-cell lymphomas and CNS lymphomas. My research is centered on the application of novel diagnostic and therapeutic strategies into clinical trials. These include imaging-studies like 18F-FDG-PET, Zr-Brentuximab-PET and Zr-atezolizumab-PET. In addition, I aim to implement novel strategies to measure minimal residual disease, and prognostic gene expression profiles in DLBCL. Linked to this I also focus on mutational analysis to study clonal evolution and prognostic / predictive values of mutations. These studies are carried out in a close collaboration with HOVON and other departments in the UMCG.
FDG-PET/CT discriminates between patients with and without lymphomas in primary Sjögren’s syndrome

OBJECTIVES: To assess the usefulness of FDG-PET/CT 1) to discriminate between pSS patients with and without lymphomas and 2) to evaluate systemic disease activity in pSS. METHODS: ACR-EULAR-positive pSS patients who underwent FDG-PET/CT were included. Scans were visually evaluated and quantitative analysis was performed by measuring standardized uptake values (SUV) of salivary and lacrimal glands and systemic regions. ROC analyses were performed to find SUV cut-off values to discriminate between lymphoma and non-lymphoma. RESULTS: 26 of the 70 included patients were diagnosed with a pSS-associated lymphoma, mostly of...
Fixed-duration venetoclax plus obinutuzumab improves quality of life and geriatric impairments in FCR-unfit patients with CLL

Chronic lymphocytic leukemia (CLL)–related symptoms and morbidity related to the advanced age at diagnosis impairs the well-being of older adult patients. Therefore, it is essential to tailor treatment according to geriatric characteristics and aim for an improvement in health-related quality of life (HRQoL) as a primary treatment goal. In the HOVON139/GiVe trial, 12 cycles of fixed-duration venetoclax plus obinutuzumab (Ven-O) were shown to be effective and tolerable in FCR (fludarabine, cyclophosphamide, rituximab)-unfit patients with CLL (n = 67). However, prolonged venetoclax exposure as consolidation treatment led to increased...

Diagnosing post-transplant lymphoproliferative disorder (PTLD) is challenging and often requires invasive procedures. Analyses of cell-free DNA (cfDNA) isolated from plasma is minimally invasive and highly effective for genomic profiling of tumors. We studied the feasibility of using cfDNA to profile PTLD and explore its potential to serve as a screening tool. We included seventeen patients with monomorphic PTLD after solid organ transplantation in this multi-center observational cohort study. We used low-coverage whole genome sequencing (lcWGS) to detect copy number variations (CNVs) and targeted next-generation sequencing (NGS) to identify...

A population-based study of transformed marginal zone lymphoma: identifying outcome-related characteristics

Histological transformation of marginal zone lymphoma (tMZL) into diffuse large B-cell lymphoma is associated with poor outcomes. Clinical characteristics associated with transformation risk and outcome after transformation are largely unknown due to scarcity of data. In this population-based study, competing risk analyses were performed to elucidate clinical characteristics associated with developing transformation among 1793 MZL patients using the Netherlands Cancer Registry. Cox regression analyses were performed to elucidate clinical characteristics associated with risk of relapse and mortality after transformation. Transformation occurred in 75 (4%) out of 1793 MZL...

Zoonotic Transmission of Vaccine-Derived Bordetella bronchiseptica.

We describe a unique case of a 43-year-old-female with a Bordetella bronchiseptica infection caused by zoonotic transmission following vaccination of her dog. With this report, we want to raise awareness of potential zoonotic transmission of live attenuated vaccines from animals to patients with impaired immunity.
