HER2 Support Group Forums - View Single Post - Thoughts on serum her 2 mets in lung/liver

I guess I'm wondering if it woudl be useful to indicate Her2 status of tumor sites not biopsied. i.e., if there is enough her2 in serum, enough of the tumor is her2 pos to suggest addition of Herceptin etc...which my mom never had. My concern is whether one isolated (liver) biopsy might be missing the larger picture and limiting treatment.

But it also seems like if there is any serum her2 at all, monitoring it in addition to tumor markers and CTC could add to the picture.

Again..I keep thinking they should gather all possible info and see what it points to. But oncs seem to be wary and lean on the phrase "but would we do with that?"
