Testing insulin‐like growth factor messenger RNA–binding protein 3 as a surrogate immunohistochemical marker for indeterminate thyroid nodules with THADA fusion in both cytologic and surgical specimens

The current findings in a limited cohort demonstrate that IMP3 is a promising surrogate marker for indeterminate thyroid nodules with THADA fusions in both cytologic and surgical specimens. In addition, IMP3 staining may aid in detecting subtle capsular or vascular invasion.
