Apport de la TEP-TDM FDG dans la prise en charge des sarcomes osseux en pédiatrie

Abstract

Bone sarcomas, including osteosarcomas (OS) and Ewing sarcomas (ES), are rare but aggressive tumors requiring specialized care. Among the available imaging techniques, FDG PET-CT (PET FDG) has taken a significant role in this oncological field in recent years. It has been established for the initial staging due to its high sensitivity for detecting extrapulmonary metastases, particularly for detecting bone and bone marrow involvement. The use of PET FDG is also developing for the evaluation of therapeutic response to neoadjuvant chemotherapy and systemic treatments in patients with advanced metastatic disease. PET FDG offers better availability and fewer acquisition constraints compared to whole-body MRI, which is important for managing a pediatric population. Furthermore, the latest technological advances will improve radiation protection for these young patients.
