Molecular Testing for Thyroid Nodules Including Its Interpretation and Use in Clinical Practice

Area of Science:

• Endocrinology
• Oncology
• Molecular Diagnostics

Background:

• Thyroid nodule management presents diagnostic challenges, often leading to diagnostic thyroidectomy for indeterminate cases.
• A small percentage of indeterminate thyroid nodules are malignant, resulting in overtreatment.
• Molecular testing offers a promising solution for improved risk stratification.

Purpose of the Study:

• To review current molecular testing platforms for indeterminate thyroid nodules.
• To highlight clinical validity and utility data for molecular testing.
• To discuss the role of molecular testing in current thyroid nodule management guidelines.

Main Methods:

• Literature review of molecular testing platforms.
• Analysis of published data on clinical validity and utility.
• Examination of inclusion in clinical guidelines (NCCN, ATA, AAES).

Main Results:

• Several molecular testing platforms are available for indeterminate thyroid nodules.
• Studies demonstrate the accuracy and utility of molecular testing.
• Molecular testing is now integrated into major clinical guidelines.

Conclusions:

• Molecular testing is a valuable adjunct for managing indeterminate thyroid nodules.
• It improves diagnostic accuracy and aids in surgical decision-making.
• Incorporation into guidelines reflects its established clinical utility.
