Clinical Validation of ThyroidPrint: A Gene Expression Signature for Diagnosis of Indeterminate Thyroid Nodules

A clinical trial is proposed, to clinically validate, in a US population, the diagnostic performance of a new genetic test (ThyroidPrint). It will determine the nature of thyroid nodules that have been informed as indeterminate by cytology through a fine needle aspiration (FNA). The Genetic Classifier for Indeterminate Thyroid Nodules is a test that determines the expression of a panel of 10 biomarkers (CXCR3, CCR3, CXCl10, CK19, TIMP1, CLDN1, CAR, XB130, HO-1 and CCR7). Gene expression data is analyzed through an algorithm that generates a composite score that predicts the risk of malignancy. It´s intended use is for patients with thyroid cytology as indeterminate (Bethesda III and IV, according to The Bethesda System for Reporting Thyroid Cytopathology). This test uses a fine needle aspiration (FNA) sample.

Stanford is currently accepting patients for this trial.
