title: American Society of Clinical Oncology 2007 clinical practice guideline update on the role of bisphosphonates in multiple myeloma.
abstract: OBJECTIVE
  To update the recommendations for the use of bisphosphonates in the prevention and treatment of bone disease in multiple myeloma. The Update Committee expanded the guideline to include a discussion of osteonecrosis of the jaw (ONJ).
  
  
  METHODS
  For the 2007 update, an Update Committee composed of members from the full panel completed a review and analysis of data published since 2002. Searches of Medline and the Cochrane Collaboration Library databases were performed.
  
  
  CONCLUSIONS
  For multiple myeloma patients who have, on plain radiograph(s) or imaging studies, lytic destruction of bone or spine compression fracture from osteopenia, intravenous pamidronate 90 mg delivered over at least 2 hours or zoledronic acid 4 mg delivered over at least 15 minutes every 3 to 4 weeks is recommended. Clodronate is an alternative bisphosphonate approved worldwide, except in the United States, for oral or intravenous administration. New dosing guidelines for patients with pre-existing renal impairment were added to the zoledronic acid package insert. Although no similar dosing guidelines are available for pamidronate, the Update Committee recommends that clinicians consider reducing the initial pamidronate dose in patients with pre-existing renal impairment. Zoledronic acid has not been studied in patients with severe renal impairment and is not recommended in this setting. The Update Committee suggests that bisphosphonate treatment continue for a period of 2 years. At 2 years, physicians should seriously consider discontinuing bisphosphonates in patients with responsive or stable disease, but further use is at the discretion of the treating physician. The Update Committee also discusses measures regarding ONJ.
