Abstract
Our objective was to evaluate the impact of 18F-FDG PET CT on the management of urachal adenocarcinoma (UrC-ADC). Methods: A retrospective analysis of patients with UrC-ADC from 2001 to 2019 at Memorial Sloan Kettering was performed. Mayo stage before 18F-FDG PET/CT, rate of detection of the primary malignancy and metastases on 18F-FDG PET/CT, Mayo stage after 18F-FDG PET/CT, and change in patient management were determined. Results: Of 21 patients with UrC-ADC before 18F-FDG PET/CT, Mayo staging was I/II in 8, III in 3, and IV in 10. 18F-FDG PET/CT detected previously unidentified metastases in 8 (38%) of 21 patients, resulting in upstaging of disease in 3 (14%) patients and a change in treatment in 4 (19%) patients. Conclusion: 18F-FDG PET/CT has clinical utility in patients with UrC-ADC by identifying metastatic disease not appreciated on anatomic imaging, leading to changes in staging and patient management.
