title: Medical oncology: Zoledronic acid for breast cancer therapy-induced bone loss.
abstract: The addition of zoledronic acid to aromatase inhibitors is associated with improved bone mineral density, but not with an effect on clinically-meaningful end points such as fractures. The oncology community should prioritize the design of trials evaluating more relevant end points, such as fragility fracture risk, for treatment-induced bone loss and critically assess the effects of such treatment on breast cancer survival.
