AC is adriamycin and cytoxin - a different mixture of chemo drugs. The mixture your oncologist is using is somewhat common for Her2 breast cancer but AC followed by taxol + herceptin is a more common regime. Do you know why your doctor picked carboplatin, taxotere + herceptin? You should ask. Carboplatin is not only used if there are mets. AC followed by taxol + herceptin is used if nodes are involved (as can be the carbo, taxotere, herceptin mix). It can be used in the adjuvant situation such as yours.
I am moderate for ER positive (50%) but I am weakly PR positive (at less than 5% - some literature calls this negative). People who are Her 2+ can be hormone negative (for both ER and PR) or strongly positive for both (or anything in between). At least half of Her2 positive women are hormone negative. It is good to be ER/PR positive, even if it is weak because after chemo, you can take an aromotase inhibitor (you will start this when you are still on herceptin alone). Herceptin and the aromotase inhibitor work well together to further help prevent a recurrence.
You should ask your doctor about this too.
Do not hesitate to ask questions to your doctor or to this board and we are here to help each other out.
Have a nice weekend.
