High Thyrocalcitonin Serum Level in Neuroendocrine Tumors: Characteristics, Prognosis and Interest in Follow-Up? Abstract #1081

Introduction: Thyrocalcitonin (TCT) is usually associated with medullary thyroid cancer. However, some neuroendocrine tumors (NETs) have also high serum TCT levels.
Aim(s): The aims of this retrospective study were to assess a) characteristics and prognosis for NETs producing TCT, and b) if this marker is useful for the follow-up of these tumors.
Materials and methods: All patients with NETs and whose serum TCT was determined between 2010 and 2012 were included. Clinical, biological, and histological characteristics were studied. Previous determinations of TCT were checked in patients with high TCT, defined as TCT>100ng/L, and their levels were compared with biological and morphological follow-up.

#67 Interest of combined chromogranin A and pancreatic polypeptide for diagnosis and follow-up of gastroenteropancreatic endocrine carcinoma
Introduction: Assessment of tumor burden changes is essential for the management of well-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEPNET). Chromogranin A (CgA) is the principal tumor marker for such tumors; however, its use to evaluate morphological tumor progression is not validated. Combined CgA and pancreatic polypeptide (PP) may increase sensitivity in the diagnosis of GEP-NET.

#113 Prolonged cell survival in xenografts from human digestive endocrine tumors
Introduction: Gastroenteropancreatic endocrine tumors have the capacity to achieve very large tumor masses despite usually very low proliferative rates. This suggests that neoplastic endocrine cells may have long life spans, implying the development of specific mechanisms able to promote cell survival.
