Key clinical point: Denosumab improves bone-related outcomes in women with high-risk early-stage breast cancer.
Major finding: Denosumab was associated with longer time to first bone metastasis in patients younger than 50 years (hazard ratio [HR], 0.70; P = .018) and in premenopausal women (HR, 0.74; P = .038). Denosumab also delayed the risk for first fracture (HR, 0.76; P = .004) and first skeletal-related event (HR, 0.52; P = .001).
Study details: An exploratory analysis of randomized, placebo-controlled phase 3 D-CARE trial of 4,509 patients with stage II/III breast cancer randomly assigned to receive adjuvant/neoadjuvant chemotherapy with either denosumab or placebo.
