Aromatase inhibitors are used as adjuvant therapy for breast cancer (BC) and are associated with accelerated bone loss. Zoledronic acid (ZOL) prevents aromatase inhibitor-associated bone loss (AIBL) in postmenopausal women with BC. This analysis assessed the cost-effectiveness of ZOL for prevention of fractures in postmenopausal women with BC. ⋯ Both delayed and upfront therapy with ZOL for the prevention of AIBL and fractures in BC patients in the UK appear to result in highly acceptable cost-effectiveness ratios.
