Cytological evaluation establishes the diagnosis of a benign or malignant nodule in 70–80% of all cases, but the remaining cases lack the features needed for a definitive diagnosis. Molecular tests have been developed to assist in determining if a nodule with indeterminate cytology is benign or malignant. The first studies focused on the analysis of the most common thyroid cancer (TC) mutation, BRAFV600E. However, since many TCs are driven by other mutations, testing for ...

The ability of thyroid cells to specifically uptake radioiodine is frequently compromised in the neoplastic setting, particularly in older patients with poorly differentiated thyroid cancer and larger metastases, resulting in a 10-year survival rate of less than 10%. The mechanisms which govern cellular iodide uptake via the sodium iodide symporter (NIS) have been elucidated with increasing molecular clarity over the past 35 years. NIS is regulated in a tissue-specific manner,...
