Yes different cancers respond differently, obviously there isn't a silver bullet, but what's being suggested is dangerous and possibly life threatening and doesn't take into account that a lot of people already limit their chemo because of cost reasons and then die early. There's a whole reason trials exist and that's to determine effective doses and overall survivability. If there was a benefit seen in trials of lower doses they would already use those doses. This is junk science at best that completely ignores a massive body of research that already exists.
