[Management of bone disease in myeloma patients: zoledronic acid or denosumab?].
With improvement of survival owing to the recent implementation of new anti-myeloma (MM) agents, bone management will become more important for maintaining the quality of life (QoL) of patients. Bisphosphonates are currently the standard of care for MM-related bone disease. Zoledronic acid is recommended for newly diagnosed MM patients receiving front-line anti-MM treatment regardless of existing detectable bone lesions. Intriguingly, an overall survival benefit has been observed with zoledronic acid in patients on anti-MM treatment with documented bone disease at baseline. Denosumab, a human monoclonal antibody against RANKL, has been demonstrated to reduce bone-related events in patients with MM as effectively as zoledronic acid. Hypocalcemia is generally accepted as occurring more frequently and more severely with denosumab than with zoledronic acid, especially in patients with renal insufficiency. Bisphosphonates but not denosumab deposit in bone with a long half-life, which may make a difference in long-term efficacy as well as adverse effects. Clinical benefits of long-term anti-resorptive therapies after achieving a good response should be clarified, in order to avoid the emergence of severe complications. Impacts of new agents in combination with these anti-resorptive agents on bone metabolism have yet to be studied.
