Expression of Cocaine- and Amphetamine-Regulated Transcript is Associated with Worse Survival in Small Bowel Carcinoid Tumors Abstract #408

Introduction: Cocaine- and amphetamine-regulated transcript (CART) peptide acts both as a neurotransmitter and hormone. We recently demonstrated that CART is expressed in several types of neuroendocrine tumors.
Aim(s): The main objective of the present study was to examine whether CART expression is associated with survival in small bowel carcinoid patients. Secondary aims were to assess if CART is associated with other tumor characteristics or clinical symptoms.
Materials and methods: Specimens from 97 patients were examined for CART expression using immunohistochemistry, and a three-tier CART score was introduced. On inclusion, specimens were examined by routine histopathological methods and detailed clinical patient data were retrieved. The effect of CART on cell viability was assessed in vitro using an enteroendocrine tumor cell line.

#2683 Clinicopathological Features and Prognostic Analysis of 227 Cases with Well-Differentiated Gastric Neuroendocrine Tumors
Introduction: Gastric neuroendocrine neoplasms (g-NENs) are a group of rare tumors with a strong heterogeneity, subdivided as well-differentiated neuroendocrine tumors (NETs, type 1-3 g-NETs) and poorly-differentiated neuroendocrine carcinoma(NECs). WHO classification(2019) for digestive system tumours has carried out a new classification and grading criteria for NENs of the gastrointestinal tract recently, there is very few relevant clinical data based on this new classification, especially for gastric NETs(g-NETs).

Introduction: Development of carcinoid heart disease (CHD) is the major negative prognostic factor in patients with the carcinoid syndrome. The only effective treatment is valve replacement. However, the selection of candidates and determination of optimal timing remain unclear. Considerable variability in local treatment strategies exist
