This study evaluated the concordance of surgical outcomes with the molecular test results from ThyGeNEXT + ThyraMIR/ThyraMIRv2 testing and the false negative rate in a cohort of cases with a Bethesda category III, IV or V diagnosis. This small retrospective review examined 19 patients who underwent preoperative ThyGeNEXT+ThyraMIR/ThyraMIRv2 testing followed by a thyroidectomy.
Post-surgical histopathology revealed a low false negative rate and high positive concordance of 89.5%.
The microRNA classifier was effective in detecting malignancy, even in cases with subthreshold mutations or without common genetic alterations. Key mutations identified included TERT c.-146C>T, NRAS Q61R, and BRAF V600E.
These findings further support the utility of ThyGeNEXT+ThyraMIR/ThyraMIRv2 in enhancing risk stratification and helping guide management of indeterminate thyroid nodules and thyroid cancer.
