#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).

#2699 Dacarbazine- or Temozolomide-Based Chemotherapy in Metastatic Digestive Neuroendocrine Carcinomas in Post First-line Chemotherapy: A Retrospective Multicentric Study of the French Group of Endocrine Tumours (GTE)
Introduction: First-line chemotherapy in metastatic neuroendocrine carcinomas (NEC) is based on etoposide and platinum. However, there is no standard for second line treatment.

#2727 Gastroenteropancreatic Neuroendocrine Tumours versus Gastroenteropancreatic Neuroendocrine Carcinoma: Presentation in Tunisian Patients
Introduction: Neuroendocrine neoplasms (NENs) are divided into two groups on the basis of clinical behaviour, histology, and proliferation rate: well differentiated (low grade to intermediate grade) neuroendocrine tumors and poorly differentiated (high grade) neuroendocrine carcinoma.

#2738 Patient-Derived Organoid Models of Human Neuroendocrine Carcinoma
Introduction: Gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) is a poorly understood disease with limited treatment options. Due to its low incidence and wide tissue distribution few representative preclinical models are available

#2864 Irinotecan-Based Regimens for the Second-Line Treatment of Extrapulmonary Poorly Differentiated Neuroendocrine Carcinomas: A Monocentric Experience
Introduction: Neuroendocrine carcinomas (NECs) are a rare subgroup of neuroendocrine neoplasms that occasionally originate from gastro-entero-pancreatic (GEP) tract. Owing to their low incidence, evidences of the effectiveness of chemotherapy are scarce. Analogously to small cell lung cancer, platinum plus etoposide (Vp16) regimens are currently the standard treatment in first-line, while little data are available on the role of second-line treatment.

#2885 Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH
Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.

#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.

#2940 Avelumab in Unresectable/Metastatic, Progressive, Poorly Differentiated, Grade 3 Neuroendocrine Carcinomas (NECs)
Introduction: Poorly differentiated, G3 NECs are associated with poor outcomes and have no effective treatment options apart from cytotoxic chemotherapy.

#2982 Comprehensive Molecular Analysis Identifies Driver Mutations in Metastases of Sporadic Well-Differentiated Neuroendocrine Tumours of the Small Intestine
Introduction: Small intestinal neuroendocrine tumours (SI-NETs) represent a heterogenous group of tumours. The molecular mechanisms which contribute to progression of SI-NETs are poorly elucidated. They are considered to be molecularly distinct from neuroendocrine carcinomas (NECs), which share oncogenic pathways with adenocarcinomas.
