As a hematologist I am always looking for new development that might improve patient care. My main research focus is on patients with Hodgkin lymphoma and multiple myeloma. I am involved in both translational and clinical studies. In cooperation with the Pathology, I am active in the field of biomarkers, such as TARC in Hodgkin lymphoma. For the design, development and execution of clinical trials, I am an active member of both international (EORTC) and national (HOVON) organizations. For example, I am the national PI of the EORTC COBRA trial in Hodgkin lymphoma. Moreover, I am co-PI of the translational research in two international trials. In addition, I am part of the Dutch guideline writing committee for Hodgkin lymphoma. In myeloma, I am investigating innovative treatment options to improve outcome.
Genomic profiling of post-transplant lymphoproliferative disorders using cell-free DNA
Published in: Journal of Hematology and Oncology
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
Published in: Blood cancer journal
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...
A significant proportion of classic Hodgkin lymphoma recurrences represents clonally unrelated second primary lymphoma
Published in: Blood Advances
Despite high cure rates in classic Hodgkin lymphoma (cHL), relapses are observed. Whether relapsed cHL represents second primary lymphoma or an underlying T-cell lymphoma (TCL) mimicking cHL is under-investigated. To analyze the nature of cHL recurrences, in-depth clonality testing of immunoglobulin (IG) and T-cell receptor (TR) rearrangements was performed in paired cHL diagnosis and recurrences of 60 patients, supported by targeted mutation analysis of lymphoma-associated genes. Clonal IG rearrangements were detected by next-generation sequencing (NGS) in 69/120 (58%) diagnosis and recurrence samples. The clonal relationship could be established...

Work and education interruption in long-term Hodgkin lymphoma survivors: an analysis among patients from nine EORTC-LYSA trials
Published in: ACTA ONCOLOGICA
Background: Disease-specific studies on the impact of Hodgkin lymphoma (HL) on education or work interruption and resumption are lacking. Material and methods: In a cross-sectional study conducted among long-term HL survivors enrolled from 1964 to 2004 in nine randomised EORTC-LYSA trials, the interruption and resumption of education/work was investigated. Survivors alive 5–44 years after diagnosis who were studying or working at time of diagnosis were included (n = 1646). Patient and treatment characteristics were obtained from trial records. Education and work outcomes were collected using the Life Situation...

The value of thymus and activation related chemokine immunohistochemistry in classic Hodgkin lymphoma diagnostics
Published in: Histopathology
Aims: Classic Hodgkin lymphoma (cHL) should be distinguished from its wide variety of histological mimics, including reactive conditions and mature B and T cell neoplasms. Thymus and activation-related chemokine (TARC) is produced in extremely high quantities by the Hodgkin/Reed–Sternberg (HRS) tumour cells and is largely responsible for the attraction of CD4+ T cells into the cHL tumour micro-environment. In the current study we evaluated the diagnostic potential of TARC immunohistochemistry in daily practice in a tertiary referral centre in the Netherlands. Methods and results: A total of 383...
