Hi Sonia,
I wont bore u with the diagnosis rollercoaster (u can read my profile for all that info) but i had the same experience in that the herceptin let me down and i ended up with several tumours plus quite a few "spots" around the brain-surgery not an option..tumours around 1.8 cm did the whole brain radio thing at the freemasons in melb (great staff!!) then started oral xeloda & tykerb mix..a follow up CT at 3 mths post radio showed tumours down to 1 cm..YAY.!!!.however the oral drugs really didn't agree with my system (apparantly has/is working really well for most)..but not me, so at 6 mth CT post radio tumours were back up to 1.9cm BOO!!! so now i am back on herceptin plus 2 chemo drugs just to keep everything at bay at least...
anyway, that has been my experience
feel free to check out my profile here and add me as a contact if you wish
Sam :)
