Autopsy study sheds light on how electric fields fight brain cancer
NCT ID NCT03194971
First seen Apr 10, 2026 · Last updated Jun 22, 2026 · Updated 13 times
Summary
This study looked at brain tissue from 20 glioblastoma patients who had been treated with Tumor Treating Fields (TTFields) before they died. Researchers examined the tissue under a microscope to count active and inactive tumor cells. The goal was to understand how TTFields affect cancer cells at the cellular level.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Tumor Treating Fields (TTFields) delivered via Optune device
What this could lead to
If successful, this study could reveal how TTFields work at a cellular level, potentially guiding better use of the therapy for glioblastoma.
What could go wrong
This is a small, observational autopsy study with only 20 patients. It cannot prove that TTFields improve survival or symptoms, and findings may not apply to all patients.
