That is a very interesting article - implying potential for "sono-immunosurgery".
One thing is that critters often have some differences in immune components from even healthy people, much less patients with severe cancer. Patients might also need to measure, preserve (ahem), and substantially rev up their immune functions.
If I were inoperable at a location, I'd certainly be looking at this, with the potentially lower sonic tx levels too, and how to highly rev up my immune system with "simple" nutrients and techniques even more. Most other treatments in the non-surgical, physical abalation category (e.g. SBRT, electroporation, RFA) are often too injurious, incomplete, inflammatory and/or immune suppressive to produce a locally curative result.
PS Social, inertial, economic and political considerations often prevent the efficient, fully intelligent application of many discoveries. 5FU (1957) is still a suboptimally applied wonder drug. Many lessons that should have been learned decades are ignored, misunderstood, forgotten and/or even deprecated. This is one reason my wife was able to handle long term chemo so well - I could pick up a cheap 5FU drug like UFT , find or figure out and apply 5-6 of those unused lessons. One particularly nasty onc, laughed at me and said I would burn up my wife's bone marrow with UFT-LV. After the initial shock of this prediction, I realized that she probably hadn't hurdled even one of those 5-6 speed bumps in 25+ years - none were "std" practice, rather than obtained through the power of just reading, much less critical reading and thinking.
