This study is for patients with metastatic breast cancerDoctors are doing this study because they want to find out if FDG-PET/CT imaging is better or worse than the usual approach for monitoring metastatic breast cancer, which is in the bone or mostly in the bone.

This study is for women or men with hormone responsive breast cancer that has already been removed by surgery and have completed any required chemotherapy or radiation. The purpose of this study is to see whether treatment with everolimus plus hormone treatment after chemotherapy will increase the time without cancer returning. The current standard treatment after chemotherapy is hormone treatment alone. Everolimus is a drug currently approved for the treatment of patients with advanced or metastatic kidney cancer. It is considered investigational for breast cancer patients. In this study subjects will get hormone treatment with either everolimus or with placebo (a pill with no medication). The combination of hormone-treatment and everolimus is experimental in patients with breast cancer.
It is expected that subjects will be enrolled in this study for approximately 54 weeks or until side effects become too great, or until cancer returns. After subjects are finished with study treatment, they will return to the clinic every six months for the first 2 years and then yearly for the next 10 years.

This study is being done for the following reasons:
•This study is being done to find out if a combination of just two chemotherapy drugs, docetaxel and cyclophosphamide, is as good as using different combinations of the chemotherapy drugs doxorubicin and cyclophosphamide, given with either docetaxel or paclitaxel, in treating your type of breast cancer. All of these drugs are used in standard combinations of chemotherapy for breast cancer.
•The researchers also want to learn about the side effects of the combinations of drugs used in this study. Side effect information will also be studied to see if there are any differences between the two-drug and three-drug chemotherapy combinations.
•In order to learn more about cancer tumors, this study includes special research tests that will be done on tumor tissue that was removed during your breast cancer surgery. Information about this study requirement will be explained to you in more detail later in this consent form.
