  2. Medullary thyroid cancer - Wikipedia

    en.wikipedia.org/wiki/Medullary_thyroid_cancer

    Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [2] MTC was first characterized in 1959.

  3. Calcitonin - Wikipedia

    en.wikipedia.org/wiki/Calcitonin

    Calcitonin assay is used in identifying patients with nodular thyroid diseases. It is helpful in making an early diagnosis of medullary carcinoma of thyroid. A malignancy of the parafollicular cells, i.e. medullary thyroid cancer (MTC), typically produces an elevated serum calcitonin level. Prognosis of MTC depends on early detection and treatment.

  4. Thyroid disease - Wikipedia

    en.wikipedia.org/wiki/Thyroid_disease

    Elevated calcitonin levels in the blood have been shown to be associated with the rare medullary thyroid cancer. However, the measurement of calcitonin levels as a diagnostic tool is currently controversial due to falsely high or low calcitonin levels in a variety of diseases other than medullary thyroid cancer. [26] [27]

    en.wikipedia.org/wiki/Thyroid_cancer

    3.2 million (2015) [6] Deaths. 31,900 (2015) [7] Thyroid cancer is cancer that develops from the tissues of the thyroid gland. [1] It is a disease in which cells grow abnormally and have the potential to spread to other parts of the body. [8][9] Symptoms can include swelling or a lump in the neck. [1] Cancer can also occur in the thyroid after ...

  6. Pentagastrin - Wikipedia

    en.wikipedia.org/wiki/Pentagastrin

    The pentagastrin-stimulated calcitonin test is a diagnostic test for medullary carcinoma of the thyroid (MTC). MTC is a malignancy of the calcitonin-secreting cells of the thyroid gland, and thus MTC is commonly associated with an elevated calcitonin level, but an elevated level may not always be obvious. The pentagastrin-stimulated calcitonin ...

  7. Multiple endocrine neoplasia type 2B - Wikipedia

    en.wikipedia.org/wiki/Multiple_endocrine...

    When medullary thyroid cancer is present, levels of the hormone calcitonin are elevated in serum and urine. [13] Under the microscope, tumors may closely resemble traumatic neuroma , but the streaming fascicles of mucosal neuroma are usually more uniform and the intertwining nerves of the traumatic neuroma lack the thick perineurium of the ...

  8. Procalcitonin - Wikipedia

    en.wikipedia.org/wiki/Procalcitonin

    Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis. It arises once preprocalcitonin is cleaved by endopeptidase. [1] It was first identified by Leonard J. Deftos and Bernard A. Roos in the 1970s. [2] It is composed of 116 amino acids and is produced by parafollicular cells (C ...

  9. Calcitonin gene-related peptide - Wikipedia

    en.wikipedia.org/wiki/Calcitonin_gene-related...

    InterPro. Calcitonin gene-related peptide (CGRP) is a member of the calcitonin family of peptides consisting of calcitonin, amylin, adrenomedullin, adrenomedullin 2 (intermedin) and calcitonin‑receptor‑stimulating peptide. Calcitonin is mainly produced by thyroid C cells whilst CGRP is secreted and stored in the nervous system. [1]
