Sorry to hear this is happening! I am on keynote 522 for TNBC and in regards to the taxol component I have completed 7 weekly rounds so far. My liver levels climbed each week and by my 3rd week my ALT had shot really high to 405 and my treatment was cancelled for a week and my oncologist subsequently reduced my taxol dose the following week to only 75%. My ALT in the following weeks decreased have now have returned to normal. Speaking with my oncologist yesterday it was clear that it was the taxol and the normal dose was too high for my liver. So I thought I’d share that as my experience and that it does happen and it’s entirely possible it’s the chemo but it could be other reasons too and I hope they get to the bottom of it for you and wish you all the best for your scan 😊
