For decades, glioblastoma has humbled medicine's most aggressive interventions, leaving patients with little more than a year of survival despite surgery, radiation, and chemotherapy. Now, researchers at Western University have asked whether electricity — long used to quiet the tremors of Parkinson's disease — might also silence the relentless division of brain cancer cells. Their therapy, called Intratumoral Modulation Therapy, uses low-amplitude electric fields implanted directly within tumors to stall cancer's biological machinery, producing an eightfold reduction in tumor growth in animal

Electric fields show promise against aggressive glioblastoma in animal studies
Glioblastoma patients currently face median survival of just over one year despite aggressive conventional treatments, with high recurrence rates near surgical sites.

Patients with glioblastoma could benefit from a non-invasive or minimally-invasive treatment option with fewer side effects than current therapies. Reduced treatment burden and improved quality of life for cancer patients and families. Potential cost savings if IMT proves more efficient than existing treatments.
Regulatory pathways (FDA approval process) will need to be established for this novel therapy class. Healthcare reimbursement policies may need updating to cover IMT devices and procedures. Increased R&D funding opportunities from government and private sources. Potential intellectual property and patent considerations for Western University and commercialization partners.
