NED Stage IV? Chemoless stage IV?

[KG1993]

I am on this website for my Mom who was dx in Aug 11. She just finished her 6th treatment of double chemo. She is meeting with oncologist at Mayo Clinic next week.
She is ready/needs a Chemo vacation. I know they plan to keep her on herceptin for at least a year. I am not familiar with some of the less toxic options.

Thanks for the replies. Keep them coming if you have any advice.
Again she had bone mets and 2 small liver mets.
