Adding zoledronic acid to anastrozole or tamoxifen therapy decreased recurrence by 35% and increased disease free survival by 36% in premenopausal breast cancer patients, according to results of the Austrian Breast and Colorectal Cancer Study Group Trial 12 (ABCSG-12). The multicenter, Phase III trial is the first large trial to demonstrate the significant antitumor benefit of zoledronic acid, said Michael Gnant, MD, Medical University of Vienna. "Adjuvant treatment with zoledronic acid should be considered in order to improve the standard of care in premenopausal breast cancer patients," he said.
