Novocure’s device burns scalps, causes chronic headaches, is a bitch to carry around, and its farcical supposed long term survival is not real, it is an extrapolation from a very small quantity of a much larger group whose data was cutoff and buried two years after patients were randomized into the trial. The field array where Optune’s mechanism of action takes place has been found to inevitably allow tumor cell escape, meaning long term survival is the exception and possibly below standard of care. The Optune trial did not even bother to exclude all non-GBM Patients. Optune sucks.
