British Columbia has become the first Canadian province to cover Tumor Treating Fields (TTFields) for adults with newly diagnosed glioblastoma (GBM), more than three years after Health Canada approved the treatment in 2022. TTFields, which has been shown to extend median survival for newly diagnosed GBM, is already reimbursed in multiple countries worldwide, and we hope to see the rest of Canada’s provinces follow BC’s lead so more patients have affordable access to this therapy.
