Breast cancer and bone metastases: a call for appropriate treatment.

PURPOSE: The aim of this study is to provide an overview of the potential barriers to uptake of bone-targeted agents for the prevention of skeletal-related events (SREs) in patients with breast cancer and bone metastases.
METHODS: A top-line literature review was conducted to identify trends in and barriers to initiating bone-targeted therapy in patients with metastatic breast cancer.
RESULTS: The majority of patients with bone metastases that are secondary to breast cancer clearly benefit from treatment with a bone-targeted agent such as the RANK ligand inhibitor denosumab or the bisphosphonate zoledronic acid, because both delay the onset of SREs. Evidence suggests, however, that these agents are not being used in these patients as per European guideline recommendations.
CONCLUSIONS: Adoption of a number of behavioral changes may help to overcome barriers to earlier initiation of treatment with bone-targeted agents in these patients. This includes raising awareness of the guidelines that are available for bone-targeted therapies, providing physician and patient education on the appropriate use of these agents, and highlighting to physicians the importance of early treatment and regular monitoring for adverse events. Earlier initiation of treatment should help to reduce the risk of SREs and thus lessen the burden that these debilitating skeletal complications place on patients and healthcare systems.
