Thyroid Gland Nodule Clinical Trial
Official title:
Retrospective-Prospective Collection of Thyroid Specimens After FNA
This trial studies how well the diagnostic deoxyribonucleic acid (DNA) methylation signature works in detecting thyroid cancer in patients with thyroid nodules. Using diagnostic testing, such as the diagnostic DNA methylation signature, may be a less invasive way to check for thyroid cancer.
PRIMARY OBJECTIVES: I. To validate a novel epigenetic thyroid nodule diagnostic test, diagnostic DNA methylation signature (DDMS) in a retrospective-prospective study with leftover of fine needle aspiration biopsies. OUTLINE: Previously collected FNA aspiration specimen samples are analyzed via DDMS assay. Participants undergo FNA aspiration for collection of tissue samples for analysis via DDMS assay. After completion of study, patients are followed up yearly for 5 years. ;
