A glioblastoma diagnosis changes a family’s life in an instant—especially when a tumor’s location makes surgery too risky. For patients facing this aggressive form of brain cancer, treatment often involves difficult decisions, profound uncertainty, and the challenge of continuing to live fully amid a life-altering diagnosis.
In this episode of Curing with Sound, we speak with Keith Merker, a husband and father from London, Ontario, who was diagnosed with glioblastoma in 2025. Keith enrolled in a clinical trial at Sunnybrook Health Sciences Centre, investigating focused ultrasound combined with microbubbles to temporarily open the blood-brain barrier, with the goal of enabling more chemotherapy to reach the tumor. Early clinical research has recently shown a potential survival benefit from this approach, though larger studies are needed to confirm the findings.
Keith shares a candid patient perspective on undergoing focused ultrasound treatment, navigating the emotional realities of glioblastoma, and finding meaning through family, music, and a commitment to “choosing joy.” His story also highlights the important role patients play in advancing research. By participating in clinical trials, patients like Keith help researchers build the evidence needed to evaluate emerging treatment approaches and move the field forward.
Discussion highlights:
-
Experiencing Focused Ultrasound as a Patient: Keith shares a firsthand account of undergoing focused ultrasound to temporarily open the blood-brain barrier and what the treatment experience was like for him.
-
Importance of Clinical Trials: Clinical trial participants help researchers evaluate focused ultrasound in patients, generate critical evidence, and move promising applications closer to broader clinical use.
-
Choosing Joy Through Uncertainty: Discover how Keith responded to one of the most difficult periods of his life by creating Team Christmas, a music-driven initiative rooted in family, hope, and community.
