This finding (fully believing it is at best anecdotal and preliminary at this point) brought TTF "tumor treating fields" therapy to mind. In the last year or so a medical device was approved by the FDA to treat brain tumors (Optune, Novocure Inc) in which the patient uses helmet that introduces alternating electrical field though the area of the tumor ( ie the patient head). It sounds super crazy, but it seems to have reached statistical significance in a couple large brain cancer studies. There are some caveats about selection bias of patients in these studies ( e.g, patients that enrolled/stayed in the study were motivated/strong enough to carry the heavy backpack and wear an onerous helmet) but it is being used and has some scientists and clinicians scratching their heads. Novocure is expanding application to multiple other cancers.
