Economic Evaluation of Fulvestrant 500 mg Versus Generic Nonsteroidal Aromatase Inhibitors in Patients With Advanced Breast Cancer in the United Kingdom

Although fulvestrant 500 mg was found not to be a cost-effective option at a standard UK threshold of £20,000 to £30,000 per QALY, it may be relevant to apply a higher threshold due to the poor prognosis of patients with advanced breast cancer and the limited number of hormonal treatment options available for this stage of treatment. Certain subgroups may also benefit from fulvestrant as a treatment option; however, limited data are currently available to identify these subgroups.
