Concordance of Molecular Classification Based on Fine Needle Biopsy (FNB) and Surgical Samples
The purpose of this study is to determine whether results from a fine needle biopsy are the same as results from a larger sample that is acquired from the surgical pathology using the Thyroid GuidePx® test in patients with papillary thyroid carcinoma.
• Age ≥ 18 years
• A diagnosis of papillary thyroid cancer based on a fine needle biopsy (FNB) interpreted as a Bethesda V or VI cytology
• A diagnosis of Atypia of Undetermined Significance (AUS) or Follicular Lesion of Undetermined Significance (FLUS) interpreted as Bethesda III or IV cytology (indeterminate nodule) ThyroSpec positive for BRAFV600E, TERT, rearrangements in BRAF, RET, NTRK1, NTRK3, RAS + TERT, RAS + EIF1AX, AKT1, PI3CA, CTNNB1, EGFR, rearrangements in ALK
• Tumor size \> 1 cm in maximal diameter on imaging prior to surgery
• The patient is an operative candidate
• The patient has provided consent
