Impact of ¹⁸F-FDG PET/CT on the management of adrenocortical carcinoma: analysis of 106 patients (original) (raw)

European journal of nuclear medicine and molecular imaging, 2014

Abstract

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Limited data are available about on value of (18)F-FDG PET/CT in ACC. We evaluated the impact of PET/CT on the management of ACC. We performed a retrospective review in patients with ACC who had undergone PET/CT. The impact of PET/CT on the management plan was evaluated by comparing the findings on PET/CT to the findings on contrast-enhanced CT. The sensitivity, specificity, and accuracy of each form of imaging were calculated. The correlations between PET/CT parameters, including maximum standardized uptake value (SUVmax), total lesion glycolysis, and decline in SUVmax after chemotherapy, and clinical outcome were evaluated. Included in the analysis were 106 patients with 180 PET/CT scans. Of the 106 patients, 7 underwent PET/CT only for initial staging, 84 underwent PET/CT only for restaging, and 15 underwent PET/CT for both initial staging and restaging. PET/CT changed the management plan in 1 of 22 patients (5%)...
