Аннотация
PURPOSE: Today, calcitonin assay is used for the diagnosis of thyroid medullary cancer in the context of nodular thyroid disease. Calcitonin is an excellent marker of thyroid medullary cancer but some hypercalcitoninemia can also be related to other diseases, such as renal failure, endocrine tumors other than thyroid medullary cancer and sometimes to C cell hyperplasia, which is a not well-defined situation. Recent studies contributed to define calcitoninemia thresholds, which guide decision and avoid excessive invasive treatment.
CURRENT KNOWLEDGE AND KEY POINTS: After a brief reminder of physiological role of calcitonin and assays, the difficulties encountered in interpreting hypercalcitoninemia and its potential causes other than thyroid medullary cancer are addressed. Recent studies, on large series, now allow a better knowledge of specificity and sensitivity of calcitonin measurement in patients with nodular thyroid disease and a well-argued management.
FUTURE PROSPECTS AND PROJECTS: In the future, calcitonin dosage will be ordered even more frequently, as some authors recommend it for the diagnosis of thyroid nodule. It is up to us to know how to use this remarkable marker, by considering all possible situations of benign hypercalcitoninemia and reserving aggressive treatments for patients who really need them.
