What is the malignancy risk for atypia of undetermined significance? Three years' experience at a university hospital in Turkey

Abstract

The malignancy risk for AUS reported in the present study is consistent with those reported previously and is higher than those anticipated according to the Bethesda System. This supports that a multimodal approach (clinical, radiologic, and cytopathologic) is necessary for the management of thyroid nodules diagnosed as AUS. Therefore, we suggest that the recommendation for repeat FNA following an initial diagnosis of AUS should be based on a multimodal approach for each particular patient.
