#2991 Gastroenteropancreatic (GEP) Neuroendocrine Neoplasia G3 (NEN G3) According to 2019 WHO Classification: A Comprehensive Clinicopathological Characterization Including Mismatch Repair (MMR) Proteins, PDL1 Expression and KRAS/BRAF Status

Introduction: In the 2019 WHO FOR NEN’S classification NETG3 have been distinguished from poorly differentiated neuroendocrine carcinoma (NEC). They are heterogeneous group concerning prognosis and treatment benefit.

#2162 Single Cell Copy Number Variation Analysis (CNV) of Circulating Tumor Cells (CTCs) in Neuroendocrine Tumor (NET) Patients

Introduction: The identification and characterization of CTCs as part of a minimally invasive “liquid biopsy” provides an opportunity to explore NET biology, identify therapeutic targets and investigate tumour heterogeneity.

#2022 CXCR4 Expression on Circulating Tumor Cells (CTCs) and Their Association with Bone Metastases in Patients with Neuroendocrine Tumors (NET)

Introduction: Bone metastases have been described in up to 32% of NET patients and are associated with a worse clinical outcome. Overexpression of CXCR4 in primary tumors appears predictive of skeletal involvement.

#1786 Targeted Therapies (TT) (Sunitinib and Everolimus) for Advanced Gastroenteropancreatic Neuroendocrine Tumors (GEP-NET). A Case Series

Introduction: Sunitinib (Sun) and Everolimus (Eve) are effective treatments for advanced GEP-NET. Lack of standard treatment sequencing and potential toxicities may preclude it´s use.

#1520 Osteotropism of NETs: Role of the SDF1/CXCR4 Axis in Regulating EMT

Introduction: NETs metastasize to the bone in up to 20% of patients. The SDF1/CXCR4 axis is a key determinant of osteotropism, and we showed that NETs overexpressing CXCR4 are more likely to develop bone metastases.
