Incidental Diagnosis of Parathyroid Lesions by Preoperative Use of Next-Generation Molecular Testing

Abstract

Parathyroid glands can mimic thyroid follicular lesions on fine-needle aspiration (FNA) cytology and can lead to unnecessary or incorrect surgery. Newer molecular panel tests using next-generation sequencing (NGS) include analysis of cell type-specific gene expression profiles such as parathyroid. The study aim is to determine the frequency and clinical implications of parathyroid tissue identification by molecular testing in cytologically indeterminate "thyroid" lesions. Molecular analysis of indeterminate thyroid FNA specimens is obtained routinely and relies on amplification-based NGS inclusive of PTH-specific expression profiles. For this study, we retrospectively examined the clinical data and management of patients with molecular results positive for PTH expression from May 2014 until May 2016. Among 4765 consecutive patients with indeterminate cytology for a presumed thyroid nodule, NGS instead indicated a parathyroid lesion in 20 patients (0.42%). The clinical data of 15 patients were available, and the subsequent clinical management was altered in 93% (14/15 patients), including five (33%) eucalcemic patients who could avoid unnecessary surgery. Primary hyperparathyroidism was not suspected in seven patients until the ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
