Medullary Thyroid Cancer.
نویسنده
چکیده
BACKGROUND: Medullary thyroid cancer, a tumor of the parafollicular C cells, accounts for approximately 10% of all thyroid malignancies. An estimated 75% of cases are sporadic, and the remaining 25% are familial. METHODS: The author reviews the clinical features and diagnostic tests for this entity, as well as the surgical treatment of recurrent or persistent medullary carcinoma. RESULTS: Sporadic medullary thyroid cancer typically presents as an isolated unilateral mass. Familial tumors tend to be multifocal and bilateral. In patients with multiple endocrine neoplasia type 2A, pheochromocytomas and parathyroid hyperplasia also may develop. Care is taken to avoid operating on a patient with occult pheochromocytoma. Total thyroidectomy and central lymph node dissection are the keys for successful surgical treatment. CONCLUSIONS: Surgery is the cornerstone of treatment for medullary carcinoma of the thyroid. Genetic testing using the ret oncogene allows identification of individuals who are at risk for the disease or those with early-stage disease.

Medullary Thyroid Cancer: A Review
Thyroid cancer is a malignancy of the thyroid parenchymal cells. There are four main types of thyroid cancer: papillary thyroid cancer (PTC), follicular thyroid cancer (FTC), anaplastic thyroid carcinoma (ATC), and Medullary thyroid carcinoma (MTC). Medullary thyroid cancer (MTC) is a rare neuroendocrine tumor of the thyroid gland derived from parafollicular C-cells that produce calcitonin (CT...
متن کاملGenetic and Epigenetic of Medullary Thyroid Cancer
Medullary thyroid carcinoma (MTC) is an infrequent calcitonin-producing neuroendocrine tumor that initiates from the parafollicular C cells of the thyroid gland. Several genetic and epigenetic alterations are collaterally responsible for medullary thyroid carcinogenesis. In this review article, we shed light on all the genetic and epigenetic hallmarks of MTC. From the genetic perspective, RET, ...
متن کامل99mTc-DMSA (V) in detection of metastases of medullary thyroid carcinoma
Introduction: Medullary thyroid carcinoma (MTC) is a rare thyroid cancer secreting calcitonin (CT) which is the most sensitive and specific tumor marker for MTC. This type of thyroid cancer is able to metastasize to different body areas including regional lymph nodes, lungs, liver and bone. The aim of this study was to assess the sensitivity and specificity of [99mTc-DMSA (V)] whole body ...
متن کاملRET proto-oncogene mutations in the diagnosis of medullary thyroid cancer: a review article
Medullary thyroid cancer accounts for 5-10% of thyroid carcinomas. RET proto-oncogene mutations occur in all of the hereditary MTCs and about 66% of the sporadic MTCs. So, the detection of the RET mutations is necessary for rapid and proper diagnosis and treatment. This systematic review seeks to find a comprehensive list of RET gene mutations in the diagnosis of medullary thyroid cancer. The ...

Background: Thyroid carcinoma is the most frequent malignant tumor of the endocrine system in human body and accounts for nearly 1% of all cancers. Medullary thyroid carcinoma is the third frequent of thyroid cancer and accounts about 5-8% of thyroid cancer. Osteocalcin, known as a Bone Gamma-carboxyglutamic Acid-containing Protein (BGLAP), is the most non collagenous protein. Retinol binding p...

Introduction: Medullary thyroid cancer (MTC) is an uncommon neoplasm originating from parafollicular C cells. Distant metastasis in MTC, such as axillary node involvement, is extremely rare. Case Report: The present study describes a known case of MTC with axillary lymph node metastasis in a 31-year-old woman. In 2010, she underwent total thyroidectomy and right-sided modified radical neck dis...
