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.

The microenvironment in classical Hodgkin lymphoma: an actively shaped and essential tumor component
Published in: Seminars in cancer biology

Classical Hodgkin lymphoma (cHL) is characterized by a minority of tumor cells derived from germinal center B-cells and a vast majority of non-malignant reactive cells. The tumor cells show a loss of B-cell phenotype including lack of the B-cell receptor, which makes the tumor cells vulnerable to apoptosis. To overcome this threat, tumor cells and their precursors depend on anti-apoptotic and growth stimulating factors that are obtained via triggering of multiple membrane receptors. In addition, tumor cells shape the environment by producing a wide variety of chemokines and...
Insulin-like growth factor 1 receptor is a prognostic factor in classical Hodgkin lymphoma

The interaction between the tumor cells in classical Hodgkin lymphoma (cHL) and the microenvironment includes aberrant activity of receptor tyrosine kinases. In this study we evaluated the expression, functionality and prognostic significance of Insulin-like growth factor-1 receptor (IGF-1R) in cHL. IGF-1R was overexpressed in 55% (44/80) of cHL patients. Phosphorylated IGF-1R was detectable in a minority of the IGF-1R positive tumor cells. The overall survival (OS, 98%) and 5-year progression-free survival (PFS, 93%) was significantly higher in IGF-1R positive cHL patients compared to IGF-1R negative patients (OS 83%,...

The Role of MicroRNAs in Hodgkin’s Lymphoma

In this chapter, we summarize the current knowledge on microRNA (miRNA) expression, function and putative clinical value in Hodgkin’s lymphoma (HL). HL is the second most common lymphoma subtype, and mainly affects young adults or elderly. Malignant cells in HL are scarce, usually less than 1%, and these cells are of B-cell origin. As miRNAs are involved in almost all known biological processes, deregulation of miRNAs is thought to play an important role in the pathogenesis of HL. MiRNA expression studies have been performed on HL cell lines,...
