Dear Mel,
I too am sorry to hear about your mom's condition. It looks like your doing a great job with your dad. Hang in there and be an advocate (along with your dad) for your mom.
As JaneP stated, get copies of all of your mom's recent diagnostic tests (e.g., PET scan, MRI scan, CT scan, blood tests, etc). You indicated that she had Stage IV mets to the spine, pelvis and liver. Get a copy of the medical test(s) upon which that determination was made. Ideal testing for an HER-2 positive breast cancer patient is a PET scan from the base of the neck to the lower calf and an MRI scan of the brain.
Also, obtain a copy of your mom's original 2000 pathology report. You indicated that the report states that the breast cancer was HER2 positive. Your mom should be able to get herceptin if she is HER2 +2 or +3 as measured by IHC testing or + as measured by FISH testing. It is generally known that FISH testing is a more reliable measure of HER2 status. If your mom was IHC tested in 2000, the tumor sample can be retested by FISH if the sample was preserved. It is highly unusual for a truly HER-2 positive primary breast cancer tumor to change HER-2 status upon metastasis or in Stage IV.
Also check your mom's 2000 pathology report to see if her cancer was estrogen/progesterone positive. ER+ HER-2 positive breast cancers can also be treated with anti-estrogen treatments such as Femara, Exemestane (Aromasin), and Faslodex, assuming she is post-menopausal. If she is not menopausal, there are ways to effectively create menopause for this purpose.
If you mom is HER-2 positive (i.e., +2 or +3 as measured by IHC or positive as measured by FISH), she will likely receive herceptin in combination with one or more chemotherapeutic agents. Jane P mentioned navelbine above. Accordingly, the following combos are quite effective:
1. herceptin and navelbine;
2. herceptin, taxol, (with or without cisplatin or carboplatin); and
3. herceptin & taxotere (with or without cisplatin or carboplatin).
You can search for potentially available clinical trials at
http://www.clinicaltrials.gov. under the search terms "herceptin" or "HER2/neu".
The most important thing at this point is to control your mom's pain and to obtain an accurate diagnosis with respect to the nature and extent of your mom's metastases. The cancer appears to be in the bone and liver based on your comments but I would also demand an MRI of the brain. Also, get permission from your mom to allow the doctor to speak directly with you and your dad. In this way, you and your dad can assist your mom in making decisions as you move forward.
Once you get a recommendation from your doctor, post it on the board along with relevant 2000 pathology report info and relevant recent diagnostic test info as discussed above. The women (and men) on this board have a vast amount of experience with respect to virtually every aspect of this form of breast cancer. It is an outstanding, caring and informed community. You are always welcomed here. Keep the faith and hang in there ... you're doing great!
If you have more questions, please feel free to post at any time.
