Abstract

Denosumab is a relatively new, very promising targeted therapy option for patients with giant cell tumor of bone. It has a role as a neoadjuvant therapy in borderline resectable cases and as a part of multidisciplinary management for primary unresectable lesions or metastases. However, controversies remain regarding the dose and duration of denosumab therapy for different indications, as well as the safety of denosumab relating to side effects, local recurrence, and malignant progression. We used denosumab as a neoadjuvant therapy for two cases to facilitate surgery, and as a long-term treatment for an unresectable giant cell tumor of bone.
