Familial Medullary Thyroid Carcinoma



  • Until today, 20/50 M918V carriers underwent thyroidectomy and all presented MTC/C-cell hyperplasia; the remainder carriers are on clinical follow-up. None of the M918V carriers presented clinical features of MEN 2B.[ncbi.nlm.nih.gov]

Neonatal Intestinal Obstruction
  • We now report the study of a FMTC family with four affected members and a history of fatal neonatal intestinal obstruction in the sister of the proband.[ncbi.nlm.nih.gov]

  • We suggest that parental imprinting may play a role in the ethiology of HSCR caused by mutations in the RET protooncogene.[ncbi.nlm.nih.gov]
  • However, such tumors commonly produce abnormally high levels of adrenalin and noradrenalin and may cause high blood pressure, a rapid or irregular heart rate, tremulousness, meaning tremors or involuntary muscular contractions, and cardiac arrest, which[cancer.net]


  • Two underwent non-normative thyroidectomy either two or four times without physician awareness or diagnosis of this disease at initial treatment, but with elevated Ct.[ncbi.nlm.nih.gov]


  • Several disease-causing mutations of this gene have been identified and their clinical prognosis described. The penetrance of these mutations is high; as such, carriers progress to develop medullary thyroid carcinoma at a young age.[ncbi.nlm.nih.gov]
  • In the Italian family the mean age at diagnosis is 25.8 years ( S.D. 7.8) and interestingly none of the patients have distant metastasis, suggesting a possibly better prognosis compared to RET-related fMTC.[endocrine-abstracts.org]
  • Prognosis and Survival Patients with FNMTC have cancer recurrences more common than with sporadic PTC or FTC.[shifrinmd.com]
  • As with any malignancy, staging of disease is an important part of management to inform treatment planning and prognosis.[radiopaedia.org]


  • The femoropopliteal aneurysm can be accompanied by an AAA in up to 70% of the cases.13,14 Etiology The etiology and pathogenesis of acquired aneurysmal disease are complex and have yet to be fully elucidated.[revespcardiol.org]
  • Etiology Medullary thyroid cancer can be classified into 4 types: 1) Sporadic 2) Hereditary MEN2A 3) Hereditary MEN2B 4) Hereditary familial medullary thyroid cancer (FMTC) Epidemiology In the United States, thyroid cancer comprises 3% of new malignancies[atlasgeneticsoncology.org]

  • Pathophysiology Medullary thyroid cancer (MTC) is usually diagnosed on physical examination as a solitary neck nodule, and early spread to regional lymph nodes is common. Distant metastases occur in the liver, lung, bone, and brain.[reference.medscape.com]
  • Markers of the extension of atherosclerosis, such as the presence of atheromatous plaques in the thoracic aorta, have been associated with a higher prevalence of AAA (14% vs 1.4%).19 Pathophysiology The factors that trigger a response in the form of a[revespcardiol.org]

  • CONCLUSION: It appears that preventive lymphadenectomy does not substantially improve survival, while pre-clinical diagnosis is of greater importance than surgery in improving survival and preventing recurrence.[ncbi.nlm.nih.gov]
