DNA from these samples, obtained from residual liquid\u2010based cytology material, was analyzed with the Myriapod NGS panel, targeting 16 genes implicated in thyroid cancer.

All TIR3A (low\u2010risk intermediate) nodules were histologically benign, whereas 50% of TIR3B (high\u2010risk intermediate) nodules were malignant; mutations were identified only in the malignant nodules.

The molecular test demonstrated 100% sensitivity, 95.5% specificity, 91.7% positive predictive value, and 100% negative predictive value for samples that were adequate for molecular testing. An intention\u2010to\u2010diagnose analysis that included samples inadequate for molecular testing was also performed, yielding 84.6% sensitivity, 87.5% specificity, 91.7% positive predictive value, and 84% negative predictive value.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The Myriapod NGS panel aids in the preoperative assessment of thyroid nodules.
