how herceptin works

[mimiflower07]

can some one please explain how does herceptin continue to keep NED after we complete a yr of treatment. I understand that it attaches to cancer cells but after the yr of treatment are we to assume there are no more cancer cells. Would it not make more sense to have a protocal that has pts receive herceptin on and off for several yrs giving the heart a chance to recover while still offering the protection that is needed.
just trying to understand how best to stay ahead of this...

Hi Mimi
I started a thread last year about this subject....
not so much about how it works but why we have
to stop taking it after a year if we don't have mets.

Here is the link to that thread
