#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.

#2982 Comprehensive Molecular Analysis Identifies Driver Mutations in Metastases of Sporadic Well-Differentiated Neuroendocrine Tumours of the Small Intestine

Introduction: Small intestinal neuroendocrine tumours (SI-NETs) represent a heterogenous group of tumours. The molecular mechanisms which contribute to progression of SI-NETs are poorly elucidated. They are considered to be molecularly distinct from neuroendocrine carcinomas (NECs), which share oncogenic pathways with adenocarcinomas.

#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.

#2926 O-Positive Blood Group Is Associated with Prolonged Recurrence-Free Survival Following Pancreatic Neuroendocrine Tumor (PanNET) Curative-Intent Surgical Resection

Introduction: The ABO blood group may influence the development and progression of cancer. In particular, the prognosis of pancreatic adenocarcinoma is better in patients with blood group O. This has not been extensively explored in PanNET.

#2920 Mutation Spectrums Analysis of Colorectal Adenocarcinoma and Neuroendocrine Neoplasm Based on Same Genetic Background to Reveal Tumorigenesis

Introduction: The tumorigenesis of neuroendocrine neoplasm (NEN) are still ambiguous. The therapies of NENs in colon or rectum refer to adenocarcinomas (AC) when tumor metastasis, but the response was unsatisfactory which inspired us to explore the mutation difference.
