#2935 Prior Surgical Resection and Ga-68-DOTANOC PET/CT Imaging-Based Parameters: Do These Impact Outcomes in Grade II Gastroentero-Pancreatic Neuroendocrine Tumors (GEP-NETs)
Introduction: Grade 2 GEP-NETs have inherent tumor heterogeneity seen with positive expression of somatostatin (SSTR) and glucose (GLUT) receptors. Prior surgical resection and imaging parameters on Ga-68 DOTANOC PET/C are well-established variable impacting prognosis in well-differentiated grade 1 NETs. Since the degree of differentiation is variable in Grade 2 NETs, these parameters have not been studied.

#3053 The Splicing Machinery Is Dysregulated in Low Grade Pulmonary Neuroendocrine Tumors
Introduction: Alternative splicing dysregulation is increasingly regarded as a novel cancer hallmark influencing all key tumor features. We have shown that neuroendocrine tumors (NETs) overexpress aberrantly spliced variants of neuropeptides and receptors that increase tumor malignancy. More recently, we discovered that the splicing machinery is dysregulated in pituitary and pancreatic NETs. To date, the status of this machinery in low grade pulmonary NETs is largely unknown.

#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.

#2865 Can the Efficacy of Etoposide-Platinum Chemotherapy Be Predicted by p53/pRb Status in Grade 3 Neuroendocrine Neoplasms (G3 NEN)?
Introduction: Etoposide-platinum (EP) chemotherapy has long stood as the reference treatment of grade 3 neuroendocrine neoplasms (G3 NEN). However, G3 NEN are heterogeneous, including well differentiated tumours (NET) and poorly differentiated carcinomas of large (LCNEC) or small (SCNEC) cell type, whose identification can be challenging and response to EP be very variable, usually low in NET.

#2896 Comparative Genomic Analysis of High Grade Neuroendocrine Neoplasms across Diverse Organs
Introduction: Grade 3 neuroendocrine neoplasms (G3 NENs), if poorly differentiated, have a median survival of 10-19 months. Little is known regarding biologic differences between G3 NENs from different primary sites, most commonly GI and lung.

#2904 Prognosis and Management of Advanced Digestive Well-Differentiated Grade 3 Neuroendocrine Tumors (G3 NETs): A NET-CONNECT Study Performed in Four Expert Centers
Introduction: G3 NETs are rare tumors with poorly defined prognosis and management.

#2951 Analysis of Discordance between Biopsy Grade and Surgical Pathology Grade in Resected PanNEN Patients
Introduction: In PanNEN cases, treatment strategies are decided by tumor localization, volume and grade. In unresectable or metastatic cases, tumor grade is determined by biopsy specimen obtained from EUS-FNA and diagnostic accuracy of biopsy according to WHO classification 2017 is important for decision making of treatment.

#3010 International Validation of a Nomogram to Predict Recurrence after Resection of Grade 1 and 2 Pancreatic Neuroendocrine Tumors
Introduction: A prediction model to predict recurrence within 5 years after surgery for nonfunctional pancreatic neuroendocrine tumors (PanNets) was recently published. This model includes WHO tumor grade, lymph node status and perineural invasion as predictors.

#2683 Clinicopathological Features and Prognostic Analysis of 227 Cases with Well-Differentiated Gastric Neuroendocrine Tumors
Introduction: Gastric neuroendocrine neoplasms (g-NENs) are a group of rare tumors with a strong heterogeneity, subdivided as well-differentiated neuroendocrine tumors (NETs, type 1-3 g-NETs) and poorly-differentiated neuroendocrine carcinoma(NECs). WHO classification(2019) for digestive system tumours has carried out a new classification and grading criteria for NENs of the gastrointestinal tract recently, there is very few relevant clinical data based on this new classification, especially for gastric NETs(g-NETs).

#2725 Upfront Surgery in Patients with High-Grade GEP NEN and MINEN: A Nordic Multicenter Study of 201 Patients
Introduction: Surgery is the principal treatment for loco-regional gastroenteropancreatic (GEP) neuroendocrine tumors (NET). However, whether surgery is beneficial in high-grade neuroendocrine neoplasms (NEN) and mixed neuroendocrine-non neuroendocrine neoplasms (MiNEN) is not known.
