My question:
I have been on Tyberb since December of 2006. My recent scans(CT and Bone) show stable disease with no progression since starting the Tyberb/Xeloda, although my CA15-3 tumor marker is rising. What information does GSK have about tumor markers and Tykerb? Is there any evidence that Tyberb may contribute to rising marker levels.
Thanks so much.
