The impact of noninvasive follicular thyroid neoplasm with papillary‐like nuclear features on the performance of the Afirma gene expression classifier

Abstract

Reclassification of NIFTP significantly decreases the positive predictive value of GEC in indeterminate thyroid nodules. Nevertheless, the majority of patients with indeterminate thyroid nodules with a suspicious GEC result in the study institution have undergone total thyroidectomy. This finding raises concerns over reliance on a suspicious GEC result by clinicians to justify total thyroidectomy. Cancer Cytopathol 2017;125:683-91. © 2017 American Cancer Society.
