Brain Cancer Patients Live Longer By Sending Electric Fields Through Their Heads

IEEE Spectrum reports on a "radical new weapon" against brain tumors — only available since 2015. They profile a typical patient who "wears electrodes on her head all day and night to send an electric field through her brain, trying to prevent any leftover tumor cells from multiplying [and] goes about her business with a shaved head plastered with electrodes, which are connected by wires to a bulky generator she carries in a shoulder bag."

The Optune system, which bathes the brain tumor in an AC electric field, is the first new treatment to come along that seems to extend some patients’ lives. New data on survival rates from a major clinical trial showed that 43% of patients who used Optune were still alive at the 2-year mark, compared to 30% of patients on the standard treatment regimen. At the 4-year mark, the survival rates were 17% for Optune patients and 10% for the others. Patients have to re-shave their heads every few days and re-apply all the electrodes, but that’s never been a problem, according to one patient. "If you have a condition which has no cure, it’s a great motivator."
