Expression of the Truncated Somatostatin Receptor Variant Sstr5TMD4 in Medullary Thyroid Carcinoma Abstract #986

Introduction: Medullary thyroid carcinoma (MTC) is a rare tumor originating from thyroid parafollicular C cell. The only available treatment is surgical resection, which is not always feasible. Somatostatin and its receptors are expressed both in normal human thyroid C cells and in MTC, but their role has not been fully elucidated. The discovery of a truncated isoform of Sstr5, Sstr5TMD4, associated with increased invasiveness and aggressiveness in breast cancer, has opened new insight in the role of Sstr in cancers.
Aim(s): To evaluate Sstr5TMD4 expression in a series of human MTC at different stages, and to explore the role of Sstr5TMD4 in TT human MTC cell line.
Materials and methods: Sstr5TMD4 expression correlates with disease stage and that it is higher in MTC metastases v. primary site and in sporadic v. hereditary cases.

#430 mTOR Inhibitors Hamper Cell Viability in Selected Human Medullary Thyroid Carcinoma Primary Cultures
Introduction: It has been demonstrated that mTOR inhibitors have potent anti-proliferative effects in a human Medullary Thyroid Carcinoma (MTC) cell line. We here explore the possible role of mTOR inhibitors, Everolimus and BEZ235 (which also inhibits the PI3K pathway) on the effects of Insulin-like Growth Factor-1 (IGF-1) in human MTC primary cultures.

#1141 New Hybrid SPECT-CT Modality for Imaging Purposes in Patients with Medullary Thyroid Cancer (MTC)
Introduction: Loco-regional lymph node and distant metastases are found very often in patients with MTC of less than 1 cm. There is not good MTC response to systemic chemotherapy or to external been radiotherapy. Radical thyroidectomy is the main method of therapy. Early diagnosis and correct N/M-staging are extremely important for the management of MTC. New hybrid SPECT-CT γ-cameras allow the fusion of anatomical and functional modalities. SPECT-CT is used in order to optimize somatostatin-receptor scintigraphic protocols.
