Calcitonin Information for Pathologists
Summary:Calcitonin (thyrocalcitonin) is a 32 amino acid linear polypeptide hormone (molecular weight 3,421Kd) that participates in calcium and phosphorus metabolism. It is formed by the proteolytic cleavage of a larger pre-propeptide, which is a product of the CALC1 gene (CALC). In humans, it is primarily produced by the parafollicular cells (C cells) of the thyroid. Other tissues such as the lungs and intestinal tract can also synthesize calcitonin. The calcitonin receptor protein has been shown to be a member of the seven transmembrane G protein coupled receptor family, which is coupled by G5 to adenylate cyclase and thereby to the generation of CAMP in target cells.
Common Uses By Pathologists:As a marker for medullary thyroid carcinoma (MTC), especially when facing histologic subtypes such as the follicular, papillary or encapsulated variants that can pose diagnostic difficulties with follicular cellÂderived carcinomas and paraganglioma (Arch Pathol Lab Med 2008;132:359). Although highly specific, calcitonin staining may be patchy in medullary carcinomas and 5% of these tumors may be negative for this marker. In tumors with no staining and still suspected to be MTC, calcitonin and calcitonin geneÂrelated peptide mRNA can be demonstrated by in situ hybridization (Arch Pathol Lab Med 2010;134:207). To evaluate for C cell hyperplasia associated with familial MTC. High grade neuroendocrine tumors can also stain with calcitonin, and metastatic lesions can be misinterpreted as having arisen in the thyroid (Adv Anat Pathol 2004;11:202).
