Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with thyroid nodules that are 1.0 cm or larger and have been classified as indeterminate based on cytology.

Probably not a fit

Patients with thyroid nodules that do not meet the inclusion criteria or those with evidence of malignant cervical adenopathy may not benefit from this study.

What this trial studies

This observational study aims to assess the performance of the Idylla™ ThyroidPrint® Assay in predicting the nature of indeterminate thyroid nodules using clinical samples. It is a multicenter, prospective study that matches the assay results to the gold standard of surgical pathology. The primary focus is to calculate the sensitivity, specificity, and predictive values of the assay, while also evaluating its failure rate and the nature of any false results.

Why it matters

Potential benefit: If successful, this study could improve the diagnostic accuracy for patients with indeterminate thyroid nodules, potentially leading to better treatment decisions.

How similar studies have gone: Other studies have explored similar diagnostic assays for thyroid nodules, but the specific performance of the Idylla ThyroidPrint Assay in this context is being evaluated for the first time.
