Zoledronic acid has found acceptance among the oncology community for a number of applications. These include tumor induced hypercalcemia, for reducing bone pain from skeletal metastases, reducing skeletal-related events, osteoporosis, and for possibly delaying (or even preventing) skeletal metastases.

Cochrane Review

Background
Bone is the most common site of metastatic disease associated with breast cancer (BC). Bisphosphonates inhibit osteoclast-mediated bone resorption.

Objectives
To assess the effect of Bisphosphonates on skeletal events (SEs), bone pain, quality of life (QOL) and survival in women with early (E) and advanced breast cancer (ABC).

Results
Bisphosphonates reduce the incidence of skeletal events. Women with ABC and clinically evident bone metastases treated with Bs showed significant delays in the median time to SE. Treatment with Bisphosphonates does not appear to affect survival in women with ABC. Bisphosphonates in women with ABC without clinically evident bone metastases do not reduce SE incidence.

Authors' conclusions
In women with ABC and clinically evident bone metastases, Bisphosphonates (PO,IV)) reduce the risk of developing SEs and SE rate, as well as delaying the time to SE. Some Bisphosphonates may also reduce bone pain and may improve QOL.
