Abstract

PURPOSE OF REVIEW:

The molecular work-up of thyroid nodules on fine needle aspiration (FNA) cytology samples has given clinicians a new level of diagnostic information. We focus this review on the molecular techniques used in the diagnosis of thyroid cancer, especially BRAF, and the resulting management considerations that are raised.

RECENT FINDINGS:

BRAF testing offers both diagnostic and prognostic information; it has been used along with the Bethesda Thyroid FNA Classification System to offer preoperative guidance in the management of thyroid nodules. Various authors have successfully utilized molecular panels on cytologic specimens including mutations and rearrangements such as RAS and RET/PTC. Preoperative mutation detection allows initial management decisions to be made with a greater clinical confidence.

SUMMARY:

BRAF molecular testing holds promise as a possible diagnostic tool for indeterminate FNAs, and as a determinant for planning initial clinical management of thyroid nodules. Further developments in the molecular approach to thyroid cancer are expected to allow greater individualization of patient care.
