Yttrium90 Radioembolization for Progressive Medullary Thyroid Carcinoma with Exclusive Liver Metastasis Abstract #1720

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 metastases (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

#1715 Recurrence of 6mm Rectal Neuroendocrine Tumor, 14 Years after Excision
Introduction: Rectal neuroendocrine tumours (NET) constitute 25% of all the digestive NET. Predictive factors of distant metastasis are: size greater than 1cm, high proliferative index and muscularis or lymphovascular invasion. In the absence of these criteria, some authors advocate there is no need for long-term follow-up.

#1154 Selective Internal Radiation Therapy (SIRT) Radioembolisation with 90 Yttrium in Patients with Unresectable Liver Neuroendocrine Metastases in a Specialized Center. An Initial Report
Introduction: Most patients with neuroendocrine tumors present liver metastases at some point of the clinical course. Liver directed treatment, such as 90 Yttrium is a method of treatment used in patients with non-resectable liver lesions, which is effective in the control of symptoms and tumor growth.

#2245 Metastatic VIPOMA, Co-Secreting Insulin, with Complete Response to Lanreotide Combined with Capecitabine and Temozolamide
Introduction: VIPomas are rare neuroendocrine tumors (NETs) associated with vasoactive intestinal polypeptide (VIP) hypersecretion causing watery diarrhea, hypokalaemia and achlorhydria. They originate mostly in the pancreas and 60-80% are malignant. Hormonal co-secretion is rarely reported.
