Hi Rocky Mountain Gal
Sorry to hear that the numbers aren't moving downwards as hoped! I know what this feels like as I didn't meet any of the milestones required by the CML experts and I felt quite powerless and frustrated. But there are other treatments to try and I'm quite sure the specialist may be of help. I actually would perhaps favour a "younger" doctor who did her training in the TKI era, as opposed to those who qualified when CML was only treatable by a bone marrow transplant as they might be more up to date with current treatments.
My CML journey has also been complicated and I've twice been at a point where I thought I was losing this battle because of my unusual situation. My advice would be, first of all, not to panic as there are many options. There are other TKIs that may work better than the dasatinib as they target different areas - this new asciminib is not even a TKI, but works in a completely different way and may well work for you. I might be put on it soon myself.
Have you had a mutation test? There are many possible mutations and some drugs work well against one and not at all against others; so it may well be that you have a type of CML that is resistant to dasatinib in some way. Below is a quote from an article I read that shows the efficacy of different drugs against different mutations, and it shows that there are some that are resistant to dasatinib but sensitive to nilotinib, for example.
"In vitro data and clinical trials, however, suggest that mutations affecting three residues, E255K/V, Y253H and F359C/V, are less sensitive to nilotinib, whereas V299L, F317L, E255K/V and Q252H appear to be less sensitive to dasatinib. If patients have one of these mutations, they should be treated with the drug that is known to be active against the specific mutation." (from an article by G Saglio (2012): Second-generation TKIs: which and when?)
Second, I'd advise you to do some reading and research yourself but ONLY if you are the kind of person who wants to read and learn more, because there is some negative research out there too. In both of my "events" during my CML journey, I found obscure bits of research that helped my doctor better understand my situation. The first study showed that only 9 other people in the world had experienced my unique brand of side effect, and I escaped treatment for lymphoma after showing my doctor this article! I've found that we have to be our own best advocates.
I will keep you in my thoughts and prayers, and try to send as many positive vibes from this bottom tip of Africa your way as I possibly can! When I went through a serious crisis last month, I so appreciated all the thoughts and prayers and comments from this community - please let us know how you get on so that we can continue to support where possible. These drugs work so effectively for so many that we are often the exception, but there are ways to fight and bring this disease under control!
Best wishes
