#3034 Somatostatin Analogs for Pancreatic Neuroendocrine Tumors: Is There Any Benefit When Ki-67 Is ≥ 10%?

Introduction: The antiproliferative effect of first-line long acting somatostatin analogs (SSA) in advanced gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs) was shown in the PROMID and the CLARINET trials. Efficacy data in pancreatic NETs (PanNETs) with Ki-67 ≥ 10% are limited.

#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.

#2883 Comparison of Somatostatin Analogues in Metastatic Gastroenteropancreatic Neuroendocrine Tumors from a Bayesian Perspective: The GETNE-TRASGU Study

Introduction: Somatostatin analogues (SSA), octreotide LAR (Oct) and lanreotide autogel (Lan), significantly prolong progression-free survival (PFS) in patients with well-differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NET). However, comparative data are not available and randomized trials comparing both SSAs are unlikely to be conducted.

#2875 Immunotherapy as Second-line Treatment in Grade 3 Neuroendocrine Carcinomas: A Prospective Case Series from an ENETS Center of Excellence

Introduction: Metastatic WHO grade 3 extra-pulmonary neuroendocrine carcinomas (EP-NEC) have a poor prognosis and optimal treatment after first-line platinum-etoposide chemotherapy remains unclear. A recent, small phase II study combining ipilimumab and nivolumab showed promising results
