32 year old w/ HER2+++/Mitral Valve Prolapse & Herceptin???

[SunDiego]

Question all... my wife just started TCH two weeks ago (1 of 6 completed). Been reading a lot about Tykerb as well and think it could be a good addition to the treatment. Is that possible?
Can one take TCH and add Tykerb? If no, when is Tykerb introduced?
We're also wanting to get her on TDM-1 (but don't want to have to qualify with progression).
In absense of progression, can one add Tykerb to Taxotere, Carboplatin and Herceptin?
Thanks,
