#3005 Comparison between Tang and WHO 5th Edition Grade Classification for Goblet Cell Adenocarcinomas

Introduction: Appendiceal GCAs (previously Goblet Cell Carcinoids) are composed of cells with secretory phenotypes. Several grading systems to predict behaviour are available (e.g.Tang). The latest WHO 5th edition adopted a grading system similar to colon adenocarcinomas.

#2976 Incidence of Appendiceal NEN and Adherence to Pathological Classification Rules and Treatment Guidelines: Results of the Population Based Cancer Registry in Belgium

Introduction: Classification of appendiceal neuroendocrine neoplasms (aNEN) changed significantly over the years and treatment algorithm remains a matter of debate.

#2965 Molecular Signature of Rectal Neuroendocrine Neoplasia

Introduction: Rectal neuroendocrine tumors are rare neuroendocrine neoplasias (NEN). Little is known about prevalence and type of somatostatin receptor subtypes (sstr) expression and somatic mutations in relation to long-term clinical outcome.

#2953 Temporal Trends in Incidence, Presentation and Work-Up of Neuroendocrine Neoplasms of the Appendix

Introduction: Although temporal trends in incidence and prognosis of neuroendocrine neoplasms have been described in the literature, data regarding trends in Appendiceal Neuroendocrine Neoplasms (ANENs) is limited.

#2927 Systemic Chemotherapy for Inoperable Goblet Cell Adenocarcinomas (GCAs) and the Role of Anti-EGFR Antibodies

Introduction: Appendiceal GCAs (previously Goblet Cell Carcinoids) have variable behaviour. Systemic chemotherapy (Chemo) is often extrapolated from colon cancer. KRAS mutations (KRAS-mut) are rare and more often present in Tang-C/high grade. The role of anti-EGFR antibodies (MoAb) is unknown.
