ABSTRACT
Background:
The usefulness of positron emission tomography (PET) with fluorine-deoxyglucose (FDG) in sarcomas and non-sarcoma non-epithelial (NSNE) tumors is not clearly defined.Aim:
To report a Chilean experience with NSNE tumors evaluated using PET with FDG. Material andMethods:
Retrospective review of the database of a PET laboratory. Demographic data, indications and metabolic findings were compared with conventional imaging in 88 adults and children with diverse bone and soft tissue sarcomas as well as 24 gastrointestinal stromal tumors (GIST), 6 pleural malignant mesotheliomas in adults, and 9 medulloblastomas in children.Results:
FDG showed good concordance with conventional imaging in NSNE tumors. It was helpful for staging, restaging, follow-up after treatment and for the detection of new not previously suspected lesions.Conclusions:
PET with FDG could have a prognostic role and help in patient management, mainly in musculos-keletal and high grade or less differentiated sarcomas. In GIST, it was a good tool for immunotherapy control.Palavras-chave
