#2887 CHOI Criteria Are More Accurate Than RECIST in Advanced Pancreatic Neuroendocrine Tumors Treated with Sunitinib: Data from the CRIPNET-GETNE1504 Study

Introduction: Comparative data suggest greater accuracy of Choi vs RECIST in some cancers such as pancreatic neuroendocrine tumors (panNET) treated with antiangiogenic agents.

#2133 Clinicopathological Features of the High Grade Pancreatic Neuroendocrine Neoplasms

Introduction: The high grade pancreatic neuroendocrine neoplasms (PanNENs) include well-differentiated tumors (WD-NETs) with elevated proliferation and poorly differentiated carcinomas (PD-NECs).

#2037 Stromal Immune Contexture Predicts Disease-Free Survival in Gastro-Entero-Pancreatic Neuroendocrine Neoplasms (GEP-NENs)

Introduction: Stromal Immune Contexture (SIC) helps predict prognosis in solid Tumors (T) but has been poorly investigated in gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs). We tested whether GEP-NENs profiling for adaptive immunity-related SIC markers, as well as inflammatory (COX2),EMT [Beta-catenin (B-cat)] and oncogenic pathway signaling (pS6) markers,could improve Ki67 and/or MO-based prediction of OS and DFS.

#1780 PD-L1 Is Expressed in a Subset of Pancreatic Neuroendocrine Tumors (pNET)

Introduction: Programmed death 1 (PD-1) is an immune inhibitory receptor expressed on several immune cells, interacting with two ligands, PD-L1 and PD-L2. The former is expressed in many human cancers and is used as a selection criterion for indication of checkpoint inhibitor therapies. PD-L1 is also a potential target for checkpoint inhibitors in pNET therapy, however no data on prevalence of PD-L1 expression and potential associations to clinico-pathologic features is available.

#1777 Tumour Size Is Not a Reliable Criterion for Resection of Patients with Non-Secreting Pancreatic Neuroendocrine Tumours: Results of an International, Multi-Centre, Operative Cohort

Introduction: Small pancreatic neuroendocrine tumours (pNETs) present a management dilemma between surveillance and resection.
