Yttrium-90 Radioembolization for Progressive Medullary Thyroid Carcinoma with Exclusive Liver Metastasis

#1717

Introduction: Medullary thyroid carcinoma (MTC) is a well-differentiated neuroendocrine tumor and accounts for 5-10% of all thyroid cancers. Distant metastases frequently involve the liver and patient’s survival after diagnosis is around 20% at 10 years

Aim(s): Report the efficacy of Yttrium90 radioembolization in a MTC with exclusive liver metastasis (LM)

Materials and methods: Male patient, 62 years old, underwent total thyroidectomy and bilateral neck dissection in 2010. Histology showed MTC, with 3.5 cm and microscopic extra-thyroid extension, pT3N0. Postoperative levels of calcitonin (CT) were 47 pg/mL (<18.2 pg/mL) and CEA 4ng/mL (<3.4 ng/mL). An hereditary form of MTC was excluded
