Short Bio:

Sorensen Lab

Dr. Poul Sorensen is a board certified anatomic pathologist, specializing in the molecular pathology of pediatric cancers. He undertook his undergraduate, medical, and PhD degrees at the University of British Columbia (UBC) and McGill University, Montreal. He completed postdoctoral training at the University of Minnesota, Minneapolis and Children’s Hospital Los Angeles, University of Southern California, after his Pathology training.  He then returned to Vancouver to start his own laboratory at Children’s and Women’s Hospital in Vancouver. Dr. Sorensen holds the Asa and Kashmir Johal Endowed Chair in Childhood Cancer Research, and he is Professor of Pathology and Laboratory Medicine at UBC. Dr. Sorensen’s research laboratory is located in the Department of Molecular Oncology at the BC Cancer Research Centre, where he is a distinguished scientist. His research focuses on targeting aberrant signaling pathways that are activated in childhood cancers and breast carcinoma.

Dr. Sorensen’s laboratory uses a combination of genetic and biochemical approaches to identify proteins that are specifically altered in human tumours. His laboratory has discovered many novel genetic alterations in childhood cancer and breast tumours, and these discoveries have been translated into new diagnostic tests for specific tumours, and have advanced our understanding of how the involved proteins transmit signals that cause cells to become cancerous. Such information then allows for the rapid implementation of strategies to target these proteins therapeutically. Dr. Sorensen is also the Chair of the Translational Research Committee of the Children’s Oncology Group (COG), the largest pediatric oncology clinical trials network in the world.

Research Interest

Discovery and Development of Optimal Immunotherapeutic Strategies for Childhood Cancers

High-risk pediatric cancers remain the leading cause of mortality in childhood, and current standard approaches to treat pediatric cancers frequently induce unacceptable life-long morbidity. This multi-center collaborative effort focuses on identifying and understanding the fundamental mechanisms leading to high-risk childhood cancers, including how these malignancies evolve to evade the immune system and resist modern therapies. These discoveries will subsequently be translated into novel new immunotherapeutic strategies for children, adolescents and young adults with cancer, which are predicted to improve cure rates while diminishing the long-term toxicity experienced by survivors.

Immunogenomics to Create New Therapies for High-Risk Childhood Cancers

The St. Baldrick’s Foundation – SU2C Pediatric Cancer Dream Team is a collaboration between pediatric cancer researchers in the largely disparate disciplines of cancer genomics and immunotherapeutics. The team will focus on developing new, targeted immunotherapeutics for the most difficult-to-cure childhood cancers.

New classes of therapeutics are needed to improve survival of children with cancer and decrease the physical, emotional, and financial life-altering costs of curative therapies. The Team has used new technologies in the field of cancer genomics, epigenetics and proteomics to discover and validate new targets for immunotherapy. They have built new antibodies, antibody-drug conjugates and CAR T cells to attack these targets. The team has innovated in developing new immunotherapies, discovering basic mechanisms of effectiveness (or lack thereof) in both antibody and cellular engineering, and developed novel methods to monitor clinical effectiveness and toxicity. The team has opened 25 clinical trials and have treated 688 pediatric patients with cancers that have resisted treatment. They demonstrated the potency of immunotherapy against acute lymphocytic leukemia (ALL), as well as defined mechanisms for how these cancers cells develop resistance. They have also made progress against childhood solid cancers, with many emerging therapeutics just entering the clinics, or scheduled to enter testing over the next one to three years.
