Scientists create method to sensitize triple-negative breast cancer to common immunotherapy

Immunotherapy, which boosts the body’s immune system to kill cancer cells, has shown remarkable promise in treating many types of cancer. Now researchers have found a way to use immunotherapy against triple-negative breast cancer (TNBC), one of the most lethal forms of breast cancer. Previously, TNBC was resistant to immune checkpoint inhibitors, a common class of immunotherapies. Using a new strategy, the scientists achieved a cure rate of up to 90 per cent in mouse models.

Researchers at The Ottawa Hospital and the University of Ottawa have found that a combination of two immunotherapies – oncolytic viruses and checkpoint inhibitors – was successful in treating triple-negative breast cancer in mouse models. Triple-negative breast cancer is the most aggressive and hard-to-treat form of the disease.
