Risk of malignancy according to sub‐classification of the atypia of undetermined significance or follicular lesion of undetermined significance (<scp>AUS</scp>/<scp>FLUS</scp>) category in the Bethesda system for reporting thyroid cytopathology

Abstract

The present study suggests that cases in the AUS/FLUS category have a higher risk of malignancy than previously thought. Because of the heterogeneous nature of the AUS/FLUS category, further sub-classification might be more effective in achieving appropriate risk stratification and better clinical management.
