MammoPrint for Triple Positive?
I've just been diagnosed with 6mm IDC out of a DCIS diagnosis, came back ER+, PR+ and HER2+. Had re-excision lumpectomy today 4/1 after margins weren't clean from original lumpectomy 3/22. Surgeon also did SNB. He told me this morning he talked with the oncologist after sending her a note that I would like Oncotype or Mammoprint (Know I'm only eligible for MammoPrint due to HER2+ status), and that she told him with HER2+ she didn't want to do that testing. I go see her 4/18.
My questions for y'all are, did you have MammoPrint (or there may be another test like this I'm not aware of)? Did it make any difference? From what I understand it just tells you the likelihood of chemo working for you? I wonder if the Oncologist knows she's going to recommend chemo no matter what and the Mammoprint may just "muddy the waters?" I'll definitely be asking her on the 18th, but wanted to see if anyone has any experience with this.
I know everyone is different. My IDC is only 6mm. Can you take the HER2+ drugs (like Herceptin and Perjeta) without chemo or is that a given or is there a chance I can go back to my DCIS plan of lumpectomy, radiation, and tamoxifen?
Sorry for the rambling questions. (may still be coming off of anesthesia a bit ) I'm a planner and doer. I just want to get this moving. If I need to push her now to send off for Mammoprint so we can have the results on the 18th, I will do it. I like to have all the info I can, and I'm ready to move this process along.
