Viral therapy effective against rare bone and muscle cancers in lab models

July 18, 2017


Cancers that arise in the bone, muscle and connective tissues (called sarcomas) are relatively rare and difficult to treat. Dr. Jean-Simon Diallo and Dr. Hesham Abdelbary teamed up to see if viruses that have proven effective in other cancer models might also be able to treat sarcoma. Their comprehensive study involved five different viruses, four sarcoma cell lines and 21 sarcoma samples from patients at The Ottawa Hospital. They found that the Maraba MG1 virus was best, infecting 80 percent of the human sarcoma samples and nearly doubling the number of long term survivors in an animal model. Researchers at The Ottawa Hospital, CHEO, McMaster and uOttawa have already initiated clinical trials with this virus in other kinds of cancer, and hope to test it in sarcoma patients in the future. See International Journal of Cancer for details.

The Ottawa Hospital: Inspired by research. Driven by compassion


The Ottawa Hospital is one of Canada’s largest learning and research hospitals with over 1,100 beds, approximately 12,000 staff and an annual budget of over $1.2 billion. Our focus on research and learning helps us develop new and innovative ways to treat patients and improve care. As a multi-campus hospital, affiliated with the University of Ottawa, we deliver specialized care to the Eastern Ontario region, but our techniques and research discoveries are adopted around the world. We engage the community at all levels to support our vision for better patient care. See www.ohri.ca for more information about research at The Ottawa Hospital.

University of Ottawa: —A crossroads of cultures and ideas


The University of Ottawa is home to over 50,000 students, faculty and staff, who live, work and study in both French and English. Our campus is a crossroads of cultures and ideas, where bold minds come together to inspire game-changing ideas. We are one of Canada’s top 10 research universities—our professors and researchers explore new approaches to today’s challenges. One of a handful of Canadian universities ranked among the top 200 in the world, we attract exceptional thinkers and welcome diverse perspectives from across the globe. www.uottawa.ca
