A Novel Animal Model for Medullary Thyroid Carcinoma Abstract #788

Introduction: Medullary thyroid carcinoma (MTC) is a neuroendocrine cancer originating from calcitonin-producing C-cells. Surgical resection is the most effective treatment currently available. Understanding the molecular pathways mediating MTC is crucial for the development of novel therapies. Cyclin-dependent kinase 5 (Cdk5) and its activators, p35 and p25, have recently been implicated in MTC etiology. P25 is a cleavage product of p35 and the binding of p25 to Cdk5 leads to aberrant Cdk5 activity.
Aim(s): We present a new mouse model in which inducible expression of p25 (p25OE) in thyroid C-cells led to tumorigenesis and lethal MTC.
Materials and methods: Conditional p25OE was driven by a NSE promoter via a tetracycline transactivator system.

#2732 Prostate Metastasis of Medullary Thyroid Carcinoma in a Young Patient with MEN2B Syndrome
Introduction: Multiple Endocrine Neoplasia 2B is associated with particularly early onset medullary thyroid carcinoma (MTC). Metastatic MTC is the leading cause of early death in MEN2B. The usual sites of metastasis are neck, mediastinum, lung, liver, bone and brain.

#3074 Medullary Thyroid Carcinoma and DIPNECH: An Unexpected Association
Introduction: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumour of the C-cells of thyroid gland. Diffuse idiopathic pulmonary neuroendocrine cells hyperplasia (DIPNECH) is a rare condition, thought to be primarily a neuroendocrine proliferative process which can develop into carcinoid tumours.

#2813 Clinical Presentation and Prognosis of Patients with Medullary Thyroid Cancer
Introduction: Medullary thyroid carcinoma (MTC) is a rare type of tumor that originates from parafollicular C-cells and accounts for 3–4% of all malignant thyroid neoplasms. MTC presents as sporadic (75–80%) or inherited tumors (20–25%). Hereditary MTC is part of multiple endocrine neoplasia type 2 (MEN2).
