Welcome, Mena~
Though this is a club we are all reluctant to have to join, you will find not only a great deal of information & guidance here, but friendship, compassion & support.
I was Stage IV with liver mets since my primary dx in May 2002, even progressing to "innumerable, immeasureable" after not responding to Navelbine/Herceptin.
Ultimately Taxol/Herceptin got me to NED for a year, but after 1 met resurfaced, we tried TCH. That was effective for a bit but ultimately once we were able to isolate the met to just my L lobe, I had a liver resection & have been NED in my liver ever since.
Since your doc is pleased with the progress you've made thus far, maybe he'll consider dropping the Carbo? That carbo was really tough for me-Ugh!I hated it. I found Taxol/Herceptin really tolerable.
I've also been on Gemzar/Herceptin for 2 recurrences, but that wasn't been able to hold the beast back for very long. Now I'm Tykerb/Xeloda for 2 weeks & so far doing pretty well.
Don't lose hope! The right combo is out there for you, we just have to give your body a chance to rest & recuperate, then get back in there & start swinging with some new ammo!
Keep us posted on how you're doing, ok?
Keep the Faith~
