Bone Abstracts

Introduction: Bone metastasis pathophysiology is currently defined as a vicious circle. Indeed, tumor cells co-express RANK-L and its receptor, RANK, allowing their own proliferation and peritumoral bone resorption necessary to the lesion expansion. Odontogenic tumors, which occur within the jaw, seem to present the same pathophysiological characteristics. Thus, studying the impact on bone of RANK over-expression by the osteoclasts would permit a better understanding of those ...

Background: High zoledronic acid (ZOL) dose protocol, one of the most potent inhibitors of bone resorption, is currently evaluated in a phase III clinical trial in Europe for the treatment of malignant pediatric primary bone tumors. The impact of such an intensive treatment on the craniofacial skeleton growth is a critical question in the context of patients with actively growing skeleton, in the light of our previous studies evidencing that endochondral bone formation was tra...
