Can a simple needle biopsy replace surgery for thyroid cancer testing?
NCT ID NCT06133374
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a fine needle biopsy (a small sample taken with a thin needle) gives the same molecular classification results as a larger surgical sample in people with papillary thyroid cancer. About 130 adults with confirmed or suspected thyroid cancer will provide both sample types, and researchers will compare the results using the Thyroid GuidePx test. The goal is to see if the less invasive needle biopsy can reliably classify the cancer type, potentially reducing the need for surgery in the future.

Inclusion Criteria: * 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 Exclusion Criteria: * History of radiation to the neck for situations such as medical radiation, radiation exposure in a work environment (nuclear power plant/reactor), or radiation exposure through release of radioactive materials into the nearby environment from a nuclear power plant/reactor. * Unable or unwilling to have a fine needle biopsy * Unwilling to undergo thyroidectomy * Final pathology does not demonstrate papillary thyroid cancer * Cases where there is no clear dominant nodule * Cases where there are multiple nodules that preclude sampling of a defined nodule
