This phase II trial studies the effects of stereotactic body radiation therapy (SBRT) and the timing of treatment with androgen receptor pathway inhibitor (ARPI) plus androgen deprivation therapy (ADT) in treating patients with hormone sensitive prostate cancer that has spread from where it first started to other places in the body (metastatic), and that has come back after a period of improvement (recurrent). It also studies the effects of salvage radiation therapy (sXRT) on prostate cancer and to see if radiation to the pelvis helps prevent prostate cancer from spreading elsewhere. SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Androgen can cause the growth of prostate cells. ADT lowers the amount of androgen made by the body. This may help stop the growth of tumor cells that need androgen to grow. Androgen receptor pathway inhibitors work by blocking the effects of androgen to stop the growth and spread of tumor cells. sXRT is a targeted radiation treatment for the prostate, typically given when cancer possibly returns after surgery or radiation. Its goal is to destroy any tumor cells in the area. Giving SBRT alone with watchful waiting may be as effective in treating prostate cancer as giving SBRT together with ARPI and ADT and sXRT may be effective in treating prostate cancer and preventing it from spreading elsewhere.

The purpose of this open-label, multicenter, phase IIIb, single-arm study is to characterize the efficacy and safety of the combination of ribociclib and standard adjuvant endocrine therapy (ET) on invasive breast cancer-free survival (iBCFS), in a close to clinical practice patient population with HR-positive (HR+), HER2-negative (HER2-), Anatomic Stage Group III, IIB, and a subset of Stage IIA Early Breast Cancer (EBC).

This study will include two groups of patients: Cohort 1 and Cohort 2. Cohort 1: will help researchers learn how a medicine called imlunestrant (LY3484356) affects a specific type of breast cancer. Some patients will take both imlunestrant and another treatment to suppress their ovarian function. Some will take it without ovarian suppression. Researchers will compare the effects in breast cancer cells to those of another medicine called tamoxifen. All patients in this group will be premenopausal women who have a type of early breast cancer called estrogen receptor-positive, HER2-negative. The treatment in this group will last for up to 29 days. Cohort 2: will help researchers understand how imlunestrant affects the ovaries when it is taken without ovarian suppression. Researchers will compare the effects to those of another medicine called tamoxifen. This group will also include premenopausal women with the same type of breast cancer. The treatment in this group will last for up to 6 months.

The purpose of this study is to establish a prospective, multi-center platform research based on clinical subtypes to explore precision therapy in patients hormone-receptor-positive HER2-negative advanced breast cancer who had previously used CDK4/6 inhibitors.

Doctors leading this study would like to learn about providing cancer treatment/therapies to Nigerian women with breast cancer based on their human epidermal growth factor receptor 2 (HER2) status. This study will focus on the efficacy and safety of anti-HER2 cancer treatment before and after surgery.

This phase II trial compares leuprolide to goserelin for reducing estrogen production by the ovaries in pre- or peri-menopausal women with breast cancer. Estrogen can cause the growth of breast cancer cells. Both leuprolide and goserelin lower the amount of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. This study compares lower dose leuprolide, higher dose leuprolide, and goserelin for their ability to suppress the function of the ovaries to produce estrogen. Both doses of leuprolide may be as safe, tolerable and/or effective as goserelin in suppressing ovarian function in pre- or peri-menopausal women with breast cancer.

This is an open-label randomized phase II study in estrogen receptor positive locally advanced or metastatic breast cancer patients. The main inclusion population are either luminal subtype B by PAM50 analysis or failed less than 2 lines of hormonal therapy for locally advanced or metastatic breast cancer. The subjects have to be premenopausal or perimenopausal and are not allowed to receive any systemic chemotherapy for their locally advanced or metastatic breast cancer. Eligible subjects will be randomized into goserelin/ fulvestrant/ durvalumab (Arm A), goserelin/ fulvestrant/ capivasertib/ durvalumab (Arm B), or goserelin/ fulvestrant/ capivasertib (Arm C) at a 1:1:1 ratio. The primary endpoint is objective response rate (ORR) of the whole other three arm compared to historical goserelin/ fulvestrantcontrol arm. The major secondary endpoint will be progression-free survival or ORR compared among different treatment arms.

The purpose of this study is to establish a prospective, single-center platform research based on clinical subtypes to explore precision neoadjuvant therapy in patients with operable breast cancer who met the indications for neoadjuvant chemotherapy and by the update of basic translational research in the center, especially the refinement of typing, the discovery of new targets and the development of novel targeted drugs, verified the effectiveness of new targeted drugs in neoadjuvant therapy.
