Dr. Kridel is a Clinician-Scientist at Princess Margaret Cancer Centre. His research interests include lymphoma genomics and their correlation with treatment response, as well as the discovery of novel therapeutic approaches to improve patient outcomes. He completed his medical training and medical oncology residency in Belgium and Switzerland, and obtained his PhD from the University of British Columbia.
We have an interest in B-cell lymphomas and are focusing on scenarios that are associated with poor outcome such as early progression after treatment, transformation to aggressive lymphoma and relapse in the central nervous system. We are applying cutting-edge tools to primary patient samples to unravel tumour heterogeneity and to develop novel, innovative biomarkers to predict outcome in lymphoma. Furthermore, we are leveraging novel findings from discovery platforms to elucidate mechanisms of lymphoma pathogenesis, tumour evolution and treatment resistance. Our ultimate goal is to improve patient outcomes through a better understanding of the diversity of responses to treatment and by tailoring therapy to each individual patient.
1. Predicting outcome of follicular lymphoma using genomic approaches
Follicular lymphoma is clinically heterogeneous and treatment decision rely on clinical indices. However, the catalogue of genetic alterations observed in any given patient may provide the substrate for reponse following treatment. We mine existing and new datasets to identify novel genetic outcome predictors. The ultimate goal is to develop clinical-grade biomarkers that help us personalize therapies.
2. Understanding treatment resistance
Despite the consideration that treatment resistance ultimately contributes to lymphoma-related mortality, it is very poorly understood. Using patient-derived datasets, we try to identify genetic and phenotypic markers that are robustly associated with treatment resistance. Using functional genomics, we aim to understand how such markers cause resistance.
3. Deciphering tumour evolution
Clonal evolution is a fundamental property of how cancers evolve over time. We postulate that better understanding of clonal dynamics at play will provide us with new strategies to circumvent the emergence of resistant clones. We are trying to answer key questions related to intratumoral heterogeneity and tumour evolution using unique resources and datasets available at the Princess Margaret Cancer Centre.
4. Translational research platform
We aim to provide a comprehensive genomic research platform for clinical trials. This includes profiling of circulating tumour DNA, plasma biomarkers and tissue biopsies.
