I have been on Ibrance and Aromasin since February. My CA27-29 dropped steadily each month, and my PET scan showed a complete clinical response in July. The next month the markers began climbing but I was told no worries. They climbed again in September and by October had doubled from July. A PET scan showed three small, new lesions on my spine and sacrum. I will have one radiation treatment to "zap" them next week. I will remain on the Ibrance and Aromasin.
Has anyone else experienced a progression breakthough like this, and remained on Ibrance with success? I am frightened (of course, who isn't?) but I want to get as much out of the drug as I can. Thank you!
