Tumor marker expectations with fourth infusion of Herceptin and Perjeta

Hi Sam. Tumour markers aren't necessarily the best indication of your met activity, but getting them low is a good sign. The scans give a better indication. My markers have been pretty "normal" for about 4 years now, stable on Herceptin and Tamoxifen. Perjeta is now standard of care as well. We Her2+ women can expect to stay on these drugs for as long as they work - a long time, I hope!
Best wishes..... Pam
