Brain metastases from breast cancer have a poor prognosis. There have been few cases reported where patients with breast cancer and brain metastases respond well to endocrine therapy (tamoxifen or letrozole). Here, we report the cases of two breast cancer patients with brain metastases who responded to medroxyprogesterone acetate and fulvestrant, respectively. These cases indicate that endocrine therapy could be very effective in the management of brain metastases from breast carcinoma.
