Introduction: Medullary thyroid carcinoma (MTC) accounts for 3.5-5% of thyroid cancers. The biochemical diagnosis of MTC is based on the determination of concentration of a sensitive and specific biomarker - calcitonin (CT) as well as CEA and procalcitonin (PCT). Neuroendocrine cells have the ability to produce various proteins and neuropeptides (e.g. granin proteins and INSM-1), which are secreted into the circulation with calcitonin and can be measured in the blood as so-cal...

Objectives: In the 5th edition of the WHO Classification of Endocrine and Neuroendocrine Tumors thyroid tumors are divided into several new categories that allow for a clearer understanding of the cell of origin, pathologic features, molecular classification, and biological behavior. According to this classification there are some borderline nodules -the group of low-risk follicular cell-derived neoplasms - such as noninvasive follicular thyroid neoplasm with papillary-like nu...
