Brief Summary:
The purpose of this study is to determine whether one dose of denosumab can lead to changes in the tumor, which may decrease the ability of tumor to spread.
Detailed Description:
Breast cancer is the most common cancer among women, affecting one in eight women, and is the second leading cause of mortality from cancer. Bone metastases are a frequent complication of breast cancer, and the mechanism of breast cancer metastases to bone is an ongoing area of research.. Receptor activator of NF-kB (RANK) and its ligand (RANKL) have been identified and characterized for its role in bone remodeling. RANKL is a member of the tumor necrosis factor (TNF) family of cytokines that binds to its receptor RANK to control osteoclast differentiation, activation, and survival. RANK protein expression is not only found on osteoclasts and dendritic cells but also on T cells and mammary epithelial cells. RANK and RANKL is important for lymph node and thymus formation as well as lactating mammary gland development during pregnancy. Furthermore, the RANK/RANKL axis has been linked to progestin driven breast carcinomas and bone metastases.
RANK is expressed in 6-57% of invasive human breast cancers (depending upon the parameters for defining positivity and antibodies utilized for immunohistochemistry (IHC)), and RANKL driven hormone (progesterone -dependent proliferation, survival, and nonproliferative expansion of mammary stem cells may contribute to breast cancer initiation, progression, and recurrence.
We hypothesize that denosumab can inhibit RANKL signaling in early breast tumors which express RANK, inhibiting pro-metastatic mechanisms and reducing immunosuppression in the tumor microenvironment. This will be tested in a pre-surgical clinical trial (Phase 0) to evaluate and select the pharmacodynamics markers of RANKL inhibition in breast cancer.
