This study is for patients with invasive breast cancer among premenopausal, early-stage breast cancer with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 and 0-25. The study is being done to determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive disease-free survival (IDFS) among premenopausal patients. The drug being used in this study are aromatase inhibitors. Patients will expect to remain in the study for up to 5years.

The study is for patients that have been diagnosed with TNBC (Triple Negative Breast Cancer). The treatment drugs being utilized are sacituzumab govitecan (Trodelvy) and pembrolizumab (Keytruda). The main purpose of this study is to determine if the combination of sacituzumab govitecan and pembrolizumab can improve outcomes and delay the return of disease in subjects with high-risk early TNBC. Subjects can expect to be in this study for up to 18 months.

This study for subjects that have been diagnosed with triple negative breast cancer (TNBC) and have recently completed preoperative chemotherapy in combination with pembrolizumab, followed by breast surgery. The subjects are expected to be in this study for up to 60 months.

The study is for patients that have been diagnosed with with a certain type of breast cancer, characterized as HER2 (Human Epidermal Growth Factor Receptor 2)-negative and hormonal receptor (HR)-positive, and with a specific characteristic (molecular subtype) called HeER2-Enriched. The investigational drugs used in this study are Ribociclib and Palbociclib. The main purpose of this study is to learn determine if participants with the specific HER2-Enriched subtype will have delayed progression of the disease when treated with ribociclib compared to palbociclib. Participants can expect to be in this study for up to 5 years.

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.
