Résumé
Detection of recurrent disease is essential for treatment planning in patients with paraganglioma. The aim of this study was to compare 123I-metaiodobenzylguanidine (123I-MIBG) scintigraphy [whole-body and single-photon emission computed tomography (SPECT) computed tomography (CT) scanning] and fluorine-18-L-dihydroxyphenylalanine positron emission tomography CT (18F-DOPA PET-CT) in the re-staging of patients with known or suspected recurrent paraganglioma.
Twelve patients with known or suspected recurrent paraganglioma after initial surgery were included in the study. 18F-DOPA PET-CT and 123I-MIBG scintigraphy (whole-body and SPECT-CT scanning) were performed in all patients; the results were compared on a per patient and a per lesion basis. Cytohistology (when available) and a combination of laboratory and imaging studies and follow-up were used as reference standard; any modification in treatment planning was recorded. In all cases recurrent disease (local or distant) was confirmed by cytohistology (four cases) or at subsequent follow-up (eight cases).
All patients had positive 18F-DOPA studies (100% sensitivity) whereas nine had positive 123I-MIBG studies (75% sensitivity; P=not significant). 18F-DOPA detected 98% of lesions, whereas 38% were detected with 123I-MIBG (P=0.04). 18F-DOPA showed more lesions than 123I-MIBG in eight patients; both techniques showed the same number of lesions in two cases whereas in two patients 123I-MIBG showed a greater number of lesions. A change in treatment planning was suggested by 18F-DOPA in one patient.
These data support the superiority of 18F-DOPA PET-CT over 123I-MIBG scintigraphy to assess disease extension in patients with recurrent paraganglioma; however, in cases with inoperable disease, 123I-MIBG maintains a unique role in allowing the selection of patients suitable for 123I-MIBG therapy.
