too bad they didn't specifically deal with srs (cyber- or gamma- knife treatment)

Trastuzumab and chemotherapy improved survival in HER2-postive breast and brain cancer patients

PHILADELPHIA — The use of trastuzumab, chemotherapy and surgery among women with HER2-positive metastatic breast cancer significantly improved survival from the time central nervous system metastases were diagnosed.

Based on these study results, lead researcher Adam Brufsky, M.D., Ph.D., said, "We clearly now know that these women should get trastuzumab and potentially chemotherapy, even if cancer spreads to the brain."

"Women with HER2-positive breast cancer have a reasonable chance of living a long time with their disease, and they should be given aggressive therapy where appropriate," added Brufsky, professor of medicine and associate director of clinical investigation at the University of Pittsburgh Cancer Institute.

Ten to 16 percent of women with advanced breast cancer develop central nervous system metastases, the researchers wrote in their study, published in Clinical Cancer Research, a journal of the American Association for Cancer Research.

Brufsky and colleagues used data from the registHER study to evaluate the incidence, potential risk factors and outcomes for patients with HER2-positive breast cancer. They evaluated how patients with HER2-positive breast cancer develop brain metastases, and followed them to examine what happens thereafter.

Of the 1,023 women newly diagnosed with HER2-positive metastatic breast cancer, 377 had central nervous system metastases.

Patients with central nervous system metastases were younger, and more likely to have hormone receptor–negative disease and higher disease burden compared with those whose cancer did not spread to the brain. In addition, for those patients without central nervous system metastases at initial diagnosis, cancer progressed to the brain about 13 months after diagnosis.

For those diagnosed with central nervous system metastases, treatment with trastuzumab, chemotherapy or surgery was each associated with a significant improvement in overall survival: trastuzumab 17.5 months vs. no trastuzumab 3.8 months; chemotherapy 16.4 months vs. no chemotherapy 3.7 months; and surgery 20.3 months vs. no surgery 11.3 months.

"It is surprising that chemotherapy/trastuzumab adds to these women's survival," Brufsky said. "We thought that the brain metastases would be dominant in this regard no matter what therapy."

Thanks again Lani But trastuzumab is new to me

[Lani]

trastuzumab IS herceptin

This seems to support some other research you posted about brain mets being most common within 2 years of metastatic disease being diagnosed? Have I remembered this right? Does this suggest yet another subset of her 2 bc which behaves in a certain way?
Hope this question makes sense?

I think what I posted was that if one hadn't had brain mets within 5 years of initial diagnosis, one was unlikely to develop them.

This is only one of several articles which finds that her2+ breast cancer patients who are ER- are more likely to develop brain mets than those that are ER+

Hope this helps!
