If I were in Tanya's shoes ... actually, I was in Tanya's shoes. I was taking Gleevec, first at 400mg. but then had to have it lowered to 300 mg.due to blood suppression - and in the end it was not working for me. I ultimately was switched to taking sprycel - first at 70 mg which, research showed was way too much and impacted me dramatically (myelosuppression) and my doctor didn't hesitate and lowered me to 20 mg after just a week at 70 mg.
And surprise for me, but not my doctor, my CML responded dramatically (although I was also adding curcumin and vitamin D3 by that time). I remain 'undetected' for over two years now getting ready for TFR.
so ... if I were in Tanya's shoes, switching to 50 mg, making sure my blood vitamin D level was over 50 ng/ml and ideally around 70 ng/ml and taking Curcumin, she could very well experience a great CML response with lower side effects. Over time, she could even lower her dose further to 20 mg.
Lowering dose should be a milestone worth achieving. As long as there are no blasts a patient can experiment (with their doctor's approval) to find the correct dose for them. Sooner or later, hopefully sooner, more and more doctors will be moving in that direction as experience shows success. We are ahead of the curve by about two - four years. That's why I like this forum. We learn first.
