Diagnostic and Outcome Differences between Sporadic and Familial Cases of Medullary Thyroid Cancer: A Retrospective Cohort Study Abstract #864

Introduction: Hereditary Medullary Thyroid Cancer (MTC) accounts for 20-30% of cases and has some clinically relevant peculiarities.
Aim(s): To analyze differences in diagnosis and outcome between sporadic and familial cases of MTC.
Materials and methods: All genotyped patients with MTC (n=35) diagnosed at Hospital Clinico San Carlos between 1984-2012 were included; 40% were germline mutation carriers (38.5% ATA-A, 53.9% ATA-B/C, 7.6% ATA-D). Median follow-up was 55 months (IQR 16-94). A comparative analysis was performed using Mann-Whitney U test, chi-squared test and Breslow test.

#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.

#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).

#2862 Concurrent Metastatic Pulmonary Neuroendocrine Tumor and Pituitary Macroadenoma
Introduction: The coexistence of a sellar mass in a patient with a neuroendocrine tumor, while rare, can paint the clinical picture of either a genetic syndrome, most notably multiple endocrine neoplasia syndrome type 1(MEN1) or pituitary metastasis recently more frequent probably due to the longer survival of cancer patients.

Introduction: Pancreatic neuroendocrine tumors (pNETs) are the most lethal manifestation in patients with multiple endocrine neoplasia type 1 (MEN1). Tumor size is still regarded as the main prognostic factor and therefore used for surgical decision making.
