Medullary thyroid carcinoma is a rare malignancy that arises from calcitonin-producing C-cells and frequently metastasizes to lymph nodes in the neck. Distant metastases may involve bone, lung, and liver. The infrequent number of cases limits the clinical nature and ability to optimize diagnostic tools. Here, we present a case of a micronodular radiographic pattern in metastatic medullary thyro...
Plasma carcinoembryonic antigen (CEA) levels were measured by the Z-Gel technique in 138 patients with benign thyroidopathies, 25 patients with thyroid cancer, and 141 normal persons. Levels were raised (above 5 ng/ml) in 2% of the normal subjects, in none of the patients with benign thyroidopathies, and in 20% of the patients with thyroid cancer. They were considerably raised in all cases of m...

Patients with multiple endocrine neoplasia (MEN) type 2A develop medullary thyroid cancer, which is associated with poor prognosis in its metastatic stage. Hyperparathyroidism is a common finding in both MEN 1 and 2. We report a 68-year-old patient diagnosed clinically with MEN 1 based on the presence of hyperparathyroidism and pituitary Cushing's disease with no supporting genetic evidence. T...
Note Medullary thyroid cancers (MTC) are rare tumors of neuroendocrine origin that arise from parafollicular C cells which secrete a variety of peptides and hormones including calcitonin. As opposed to the more common papillary and follicular thyroid cancer subtypes, MTC represents a rare and under-characterized form of cancer, and can cause death if untreated (Taccaliti et al., 2011). MTC can ...
Summary Established systemic treatment options for advanced thyroid cancer include the multityrosine kinase inhibitors lenvatinib and sorafenib radioactive iodine refractory differentiated (DTC) vandetanib cabozantinib medullary (MTC). Recently, COSMIC-311 study resulted in approval of DTC with progression upon and/or sorafenib; thus, first time a specific second-line therapy has been defined t...
OBJECTIVE Medullary thyroid cancer is a rare tumor that is more aggressive and has a worse prognosis than differentiated thyroid cancer. The purpose of this study was to report the demographic, clinical, and genetic characteristics of patients seen in the health care system of the community of Castilla-La Mancha over a 16-year period. PATIENTS AND METHODS Data were collected through a review ...
Serum calcitonin was determined by RIA in 59 healthy subjects (Group 1), 49 randomly selected patients with treated or untreated thyroid disorders (Group 2), and in 12 kindred of a pheochromocytoma index case (Group 3). Although most subjects in Group 2 had normal calcitonin levels, there were significant (p less than 0.001) differences between all three groups. Of the five patients in Group 2 ...
