Judiek;
Have you ever tried the Bayer Serum Her2 test? Your tumor certainly seems very aggressive and I am just wondering as....let me quote Dr. Carney:
Studies have now shown that 10-40% or metastatic breast cancer patients with a negative IHC or FISH test can have an elevated serum HER-2/neu in metastatic breast cancer. As you know, patients negative by tissue testing can't receive Herceptin. The serum HER-2/neu test is not approved to select patients for Herceptin. However, if patient has an elevated serum HER-2/neu then they should have their original primary tumor re-evaluated by the approved IHC or FISH test to see if the tumor is HER-2/neu positive. If the tumor is negative or not available you should discuss with your oncologist testing a metastatic lesion for HER-2/neu positivity by IHC or FISH. If positive, then the patient can be eligble for Herceptin, if the Oncologist recommends it. Once again, the serum HER-2/neu test is not approved for selecting patients for Herceptin but can provide guidance back to the approved tissue tests.
Your have certainly been through an awful lot. God bless.
