A society of geriatric oncology (SIOG) task force reviewed information from the literature (in PubMed) on bisphosphonates in elderly patients with bone metastases until December 2005. Additional pertinent data were obtained from the manufacturers. Bisphosphonates are recommended in the elderly with bone metastases to prevent skeletal-related events. Intravenous formulations are preferred for the treatment of hypercalcaemia. It has been recognised that zoledronic acid, ibandronate and pamidronate can effectively contribute in relieving metastatic bone pain. Creatinine clearance should be monitored in every patient, and a less renally toxic agent should be used where evidence of similar efficacy is available. The assessment and optimisation of hydration status is recommended. Due to the risk from osteonecrosis of the jaw, routine oral examination and treatment of dental problems by a dental team is recommended before bisphosphonates. Physicians should choose the most appropriate bisphosphonate. Safety precautions are particularly important in elderly patients. Further research is needed in this population. © 2006 Elsevier Ltd.
