Background. In this study we retrospectively evaluated if

F-FDG-PET-CT provided incremental diagnostic information over CI in a group of hepatoblastoma patients performing restaging. Procedure. Nine patients mean age: 5.9 years; range: 3.1–12 years surgically treated for hepatoblastoma were followed up by clinical examination, serum -FP monitoring, and US. CI CT or MRI and PET-CT were performed in case of suspicion of relapse. Fine-needle aspiration biopsies FNAB were carried out for final confirmation if the results of CI, PET-CT, and-or -FP levels were suggestive of relapse. PET-CT and CI findings were analyzed for comparison purposes, using FNAB as reference standard. Results. -FP level was suggestive of disease recurrence in 8-9 patients. Biopsy was performed in 8-9 cases. CI and PET-CT resulted to be concordant in 5-9 patients CI identified recurrence of disease, but

F-FDG-PET-CT provided a better definition of disease extent; in 4-9 cases, CI diagnostic information resulted in negative findings, whereas PET-CT correctly detected recurrence of disease.

F-FDG-PET-CT showed an agreement of 100% 8-8 with FNAB results. Conclusions.

F-FDG-PET-CT scan seems to better assess HB patients with respect to CI and may provide incremental diagnostic value in the restaging of this group of patients.
