Hi Kristina,
Re: high dose vitamin C.
It remains outside the mainstream accepted clinical 'arsenal' to use vitamin supplementation as a way of treating serious diseases/cancer, so I am not surprised your doctor cannot answer your questions about this.
Personally I use high dose vit C but via the normal digestive route rather than via IV. I have done this for many years - including during my stem cell transplant - as I can tolerate it very well. High dose C via IV is another way especially for those who experience digestive upset and cannot tolerate anything over 1 -10g. In the UK it is difficult to find clinicians within the mainstream (certainly in the NHS) who would consider offering IV services but they are available privately here in the UK as well as elsewhere.

I would add that CML was very hard to control before the revolutionary shift in treatment to TKI therapy (imatinib/Glivec) now over 20 years ago. It is not an exaggeration to call this a paradigm shift in how to successfully treat CML and save the lives of the vast majority of those diagnosed in chronic stage CML. There is still a minority population of CML patients diagnosed in later stage disease that do not respond optimally to TKI therapies, which is why there is still a way to go before we can call such therapy a cure.
However, I believe it does no harm (and probably a lot of good) to supplement a good whole food (non-processed food) diet with vitamins and minerals - especially vit C and D3 + others- but I also believe that in the case of CML this should always be as a 'complement' to TKI therapy.
I cannot stress enough just how much of a game changer TKI therapy was. As cancer patients, for those who have access to TKI therapies, we are very fortunate.
