Abstract
Background: Fluoro-2-deoxyglucose-18 (FDG) positron emission tomography (PET/CT) has utility in identifying sites of active sarcoidosis. However, the role of FDG-PET/CT in predicting treatment response and guiding therapy outside of cardiac disease is yet to be completely understood.
Research question: Do physicians agree on the utility of FDG-PET/CT in sarcoid cases, and do they agree on the appropriate treatment response, based on the associated reports?
Study design and methods: Physicians respondents were presented with a series of anonymised sarcoidosis case vignettes. The perceived utility of FDG-PET/CT in each case, as well as the ultimate treatment decision following provision of FDG-PET/CT results was assessed. Inter-rater agreement was assessed overall and per case vignette specialty using Gwet's Agreeability Coefficient (AC1).
Results: Respondents (n=215) were predominantly respiratory physicians (86.78%) experienced in sarcoidosis management (94.39%), and a third of whom had >20 years' experience (32.66%). Pulmonary sarcoidosis case vignettes had the lowest rates of FDG-PET/CT endorsement among surveyed subspecialties (38 - 64%). Overall inter-rater agreement was assessed among physicians who positively endorsed an FDG-PET/CT. Treatment rationalisation based on FDG-PET/CT report was near-chance agreement for pulmonary AC1=0.178 (N=217, 95% CI 0.125- 0.234, p=0.07) and multisystem AC1=0.296 (N=168, 95% CI 0.066 - 0.477, p=0.41) cases, while agreement was highest for cases of cardiac sarcoidosis AC1=0.797 (N=374, 95% CI 0.759 - 0.838, p=<0.05).
Interpretation: Our results indicate a low agreement between physicians regarding their management of pulmonary sarcoidosis following FDG-PET/CT. This highlights a need for further research and clarity over the role of FDG-PET/CT in the therapeutic management of pulmonary sarcoidosis.
