#2057 Morphological Factors Related to Nodal Metastases in Neuroendocrine Neoplasms of the Appendix. A Multicenter Retrospective Study

Introduction: Appendiceal NETs are usually diagnosed accidentally after appendectomy; the indications for right hemicolectomy are currently based on several parameters (tumor size, grading, Ki-67, localization, mesoappendiceal invasion, lympho-vascular infiltration). Available guidelines are based on scarce evidence inferred by small, retrospective, single institution studies.

#1654 A Single Centre Analysis of the Management of Appendiceal Neuroendocrine Neoplasms (NENs) Including Goblet Cell Carcinoids (GCC)

Introduction: Appendiceal neuroendocrine neoplasms (NENs) are usually diagnosed incidentally on histology following an appendicectomy. They include carcinoid tumours (appendiceal neuroendocrine tumours, NETs) and goblet cell carcinoids (GCC). GCC neoplasms are able to transform to an adenocarcinoma phenotype.

#876 Incidence and Prevalence of Neuroendocrine Tumors (NETs) of the Ileum and Colon (Excluding Appendiceal NETs) in Northern Ireland (NI) Over a 25-Year-Period (1988-2012)

Introduction: Incidence of NETs is quoted to be 2/100,000 with approximately 25% being tumors of the midgut, (0.5/100,000). Incidence is increasing. However, this may be in part due to improved diagnosis but it is also thought to be a true increase.
