#2870 When It Comes to the Diagnostic of Neuroendocrine Neoplasms (NEN), Not All Markers and Clones Were Made Equal. Assessment of 5 Makers in 466 NEN from 10 Anatomical Sites

Introduction: Histological diagnostic of neuroendocrine neoplasms (NEN) relies on morphological criteria and expression of several neuroendocrine marker assessed by immunohistochemistry. Systematic large evaluation of classical (chromogranin A (chrA), synaptophysin (Syn), CD56) and emerging (chromogranin B (chrB), INSM1) markers are lacking.

#2765 Role of Biomarkers in Disease Progression of NET

Introduction: Due to the non specific features of neuroendocrine tumors and lack of diagnostic biomarkers, the diagnosis is usually delayed and almost half of patients presenting with distant metastases

#1816 Multivisceral Transplantation and Vascularised Sentinel Forearm Flap for a Metastatic Small Bowel Neuroendocrine Tumour: Update on Follow-Up

Introduction: We previously reported the first documented case of a novel approach in a patient with extensive mesenteric metastases from a small bowel neuroendocrine tumour (SBNET): this combined multivisceral transplantation (MVT) and a vascularised sentinel forearm flap (VSFF) from the same donor.

#1582 Utility of Serum Chromogranin B Compared with Chromogranin A as a Biomarker in Japanese Patients with Pancreatic Neuroendocrine Tumors

Introduction: Currently, serum chromogranin A (CgA) is used as a biomarker for pancreatic neuroendocrine tumors (pNET); however, oral use of a proton pump inhibitor (PPI) and renal impairment can affect CgA.

#1558 Multivisceral Transplantation and Vascularised Sentinel Forearm Flap for a Metastatic Gut-Derived Neuroendocrine Tumour: Follow-up

Introduction: We previously reported the first documented case of a novel approach in a patient with extensive mesenteric metastases from a small bowel (SB) NET: this combined multivisceral transplantation (MVT) and a vascularised sentinel forearm flap (VSFF) from the same donor.
