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.

Expression of the c-Met oncogene by tumor cells predicts a favorable outcome in classical Hodgkin’s lymphoma
Published in: Haematologica
Access to document 10.3324/haematol.2011.056101 document
BACKGROUND: The c-Met signaling pathway regulates a variety of biological processes, including proliferation, survival and migration. Deregulated c-Met activation has been implicated in the pathogenesis and prognosis of many human malignancies. We studied the function and prognostic significance of c-Met and hepatocyte growth factor protein expression in patients with classical Hodgkin’s lymphoma. DESIGN AND METHODS: Expression of c-Met and its ligand, hepatocyte growth factor, were determined by immunohistochemistry. Prognostic values were defined in cohorts of German and Dutch patients with classical Hodgkin’s lymphoma. Functional studies were performed on...

Plasma thymus and activation-regulated chemokine as an early response marker in classical Hodgkin’s lymphoma
Published in: Haematologica
Access to document 10.3324/haematol.2011.053199 document
BACKGROUND: Plasma thymus and activation-regulated chemokine is a potential biomarker for classical Hodgkin’s lymphoma. To define its value as a marker to monitor treatment response, we correlated serial plasma thymus and activation-regulated chemokine levels with clinical response in newly diagnosed and relapsed classical Hodgkin’s lymphoma patients. DESIGN AND METHODS: Plasma was collected from 60 (39 early stage and 21 advanced stage) newly diagnosed classical Hodgkin’s lymphoma patients before, during, and after treatment, and from 12 relapsed patients before and after treatment. Plasma thymus and activation-regulated chemokine levels were...

HLA-A*02:07 Is a Protective Allele for EBV Negative and a Susceptibility Allele for EBV Positive Classical Hodgkin Lymphoma in China
Published in: PLoS ONE
Access to document 10.1371/journal.pone.0031865 document
HLA-A2 protects from EBV+ classical Hodgkin lymphoma (cHL) in Western Europe, but it is unknown whether this protective effect also exists in the Chinese population. We investigated the association of HLA-A2 and specific common and well documented HLA-A2 subtypes with EBV stratified cHL patients (n = 161) from the northern part of China. Quantitative-PCR and sequence-based subtyping was performed to identify HLA-A2 positive samples and their subtypes. 67 (42%) of the cHL patients were EBV+. There were no significant differences in percentages of HLA-A2 positivity between cHL and...

Genome-wide association study of classical Hodgkin lymphoma and Epstein-Barr virus status-defined subgroups
Published in: Journal of the National Cancer Institute
Access to document 10.1093/jnci/djr516
BACKGROUND: Accumulating evidence suggests that risk factors for classical Hodgkin lymphoma (cHL) differ by tumor Epstein-Barr virus (EBV) status. This potential etiological heterogeneity is not recognized in current disease classification. METHODS: We conducted a genome-wide association study of 1200 cHL patients and 6417 control subjects, with validation in an independent replication series, to identify common genetic variants associated with total cHL and subtypes defined by tumor EBV status. Multiple logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) assuming a log-additive genetic model...
