Abstract Purpose: Denosumab was shown to be superior zoledronic acid in preventing skeletal related events (SRE) patients with breast cancer and bone metastases a randomized, double-blind phase III study. We evaluated further results from this study complications health-related quality of life (HRQoL). Experimental Design: Patients were randomized 1:1 receive subcutaneous denosumab 120 mg (n = 1,026) intravenous placebo, or 4 1,020) placebo every weeks. Analyses reported here include the...

Giant cell tumor of bone (GCTB) is an aggressive primary osteolytic tumor. GCTB often involves the epiphysis, usually causing substantial pain and functional disability. Denosumab, a fully human monoclonal antibody against receptor activator nuclear factor κΒ ligand (RANKL), effective treatment option for patients with advanced GCTB. This analysis data from ongoing, open-label study describes denosumab's effects on analgesic use in GCTB.Patients unresectable disease (e.g. sacral or spinal...
