Impact of whole-body MRI and FDG-PET on staging and assessment of therapy response in a patient with Ewing sarcoma

Pediatr Blood Cancer. 2006 Oct 15;47(5):607-11. doi: 10.1002/pbc.20662.

Abstract

In patients with Ewing sarcoma, precise staging is not only crucial for the therapeutic regimen but also for a reliable evaluation of response to therapy. We report on a 15-year-old girl with metastatic spread of a Ewing sarcoma who, apart from conventional staging by bone scan, chest X-ray and CT, was subsidiary examined by FDG-PET and whole-body MRI before and after chemotherapy. Both modalities detected more bone lesions than the bone scan, which led to an altered strategy for radiotherapy. Both examinations might be a great asset to stage-adjusted therapy regimens, ultimately influencing patient outcome.
