title: Proven efficacy of zoledronic acid in the treatment of bone metastases in patients with breast cancer and other malignancies.
abstract: Many advanced cancers, particularly breast cancer and prostate cancer, metastasize to the bone, resulting in painful lesions and skeletal complications. Intravenous bisphosphonate therapy is an important component of palliative care for patients with bone metastases, and pamidronate has been the standard of care for patients with breast cancer and multiple myeloma since 1996. However, zoledronic acid is the first bisphosphonate shown to significantly reduce skeletal morbidity in patients with a wide range of primary tumor types. Zoledronic acid has demonstrated efficacy in the management of hypercalcemia and metastatic bone disease. In phase III studies involving more than 3000 patients with multiple myeloma, breast cancer, prostate cancer, lung cancer, and other cancers, 4 mg zoledronic acid demonstrated consistent efficacy across a range of clinical end-points, and was safe and well tolerated when infused over 15 min. Based on these studies, zoledronic acid appears to be active in patients with bone metastases irrespective of tumor type, and should be considered as the standard of care for the treatment of bone metastases.
