Researchers aren't sure how the device works, and some brain-cancer specialists are skeptical.
A wearable medical device that delivers electrical fields through the scalp helped to extend the survival of patients with lethal brain tumors, according to data presented Sunday.
In a study involving major medical centers in the United States and abroad, the novel treatment was used to administer alternating, low-intensity “tumor-treating fields” to newly diagnosed glioblastoma patients who also were getting chemotherapy. Such electrical fields may block the division of cancer cells and cause their demise, according to Roger Stupp, the study's lead investigator and a neuro-oncologist at the Northwestern University Feinberg School of Medicine.
