#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.

#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.

#2888 Progression-Free Survival as a Surrogate Endpoint in Gastroenteropancreatic Neuroendocrine Tumors Treated with Somatostatin Analogues

Introduction: Progression-free survival (PFS) has been used as surrogate endpoint in phase III trials with somatostatin analogues for gastroentero-pancreatic neuroendocrine tumors (GEP-NET). However, this endpoint has not been validated in this scenario.
