I suspect most of us have not. I have now read a number of newspaper articles and their webpages. Their emphasis is on cocktails, or a particular cocktail, of off label [off target] drugs to add to regular cancer treatments. Testing these old drugs individually for cancer treatment re-labeling is the [multi-decade?] mission of the ReDo project, kind of late for the clinics' purposes, and ours.
I did not see whether the clinics substantially added high potency supplements.
...and if so what are your thoughts
It is a small new clinic, nominally aimed at re sensitizing chemo resistant cancers to regular chemo. Also there are windows of opportunity for stand alone application periods e.g. during the 6 weeks off chemo with Avastin, before and after surgery. The parent clinic in London cites examples of apparent standalone applications.
We have had some successes with other off label drugs, like cimetidine and celebrex, with and without chemo, when combined with specific, high potency supplements
to hit cancer pathways and vulnerabiities. My experience is that these applications work best combined with intensive reading, along with more careful and intensive monitoring,where we used more frequent, extended blood monitoring more than scanning.
I interviewed a spectrum of MD doctors, from clinicians to researchers to pharma director to those with alternative views to pick up extra options. Partly it depends on how much time and money you are willing and able to invest, your background, your willingness to act independently, and your confidence in your judgement. I placed these answers in several planning contexts, "early", "mid", "late", with/without chemo, before/during/after surgery etc, not just reacting to a need this month or next.
