#2831 Immunohistochemical Profile of Digestive Neuroendocrine Neoplasms: A Retrospective Analysis in a Single Algerian Institution
Introduction: Neuroendocrine Noplasms (NEN) are rare tumours, but their incidence is clearly increasing in our country due to the improvement of diagnostic means, in particular the generalization of immunohistochemical techniques. The digestive location represents more than 70% of the cases. The anatomopathological study enables to classify the NEN in different prognostic grades according to the degree of differentiation, mitotic index and Ki67.

#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.

#2822 Outcome of Systemic Therapy in Secondary High-Grade Pancreatic Neuroendocrine Tumors
Introduction: Platinum-based chemotherapy has been the recommended treatment for metastatic high-grade pancreatic neuroendocrine neoplasms (panNEN). This strategy has been questioned for pancreatic neuroendocrine tumor grade 3 (panNET G3). The most optimal treatment strategy for low/intermediate grade panNETs that show progression to a high grade (secondary panNET G3) is unknown.

#3036 Can Ki-67 with 5.5% Be Better in Predicting Prognosis for Well Differentiated Pancreatic Neuroendocrine Tumors?
Introduction: Pancreatic neuroendocrine tumors (NETs) are rare malignancies, Ki-67 is a cell proliferation marker that has been shown to have some utility in predicting prognosis of neuroendocrine tumors. However, the ideal grading method for G1/G2 remains controversial.

#2939 Prognostic Evaluation for Gastroenteropancreatic NEC: AJCC or ENETS Staging Classification or Others?
Introduction: For poorly-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC), American Joint Committee on Cancer (AJCC) recommends to use a classification different from that for well-differentiated neuroendocrine tumor. However, this is not adopted by European Neuroendocrine Tumor Society (ENETS) staging classification.
