#2248 High Grade (G3) Gastro-Entero-Pancreatic Neuroendocrine Neoplasms: Should the New WHO Classification Apply to All?

Introduction: Grade 3 (G3) neuroendocrine neoplasms (NEN), arising from the gastro-entero-pancreatic system (GEP), are classified according to WHO 2010 and defined as having a Ki67 of > 20%. However this groups together G3 well differentiated neuroendocrine tumours (WD-NET) with poorly differentiated neuroendocrine carcinomas (PD-NEC). Recently, WHO have proposed a new classification for pancreatic NEN, with sub-division into G3 WD-NET and G3 PD-NEC

#2246 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH): Characterisation of Prevalence and Prognosis in the Pulmonary Carcinoid Population

Introduction: DIPNECH is considered a rare condition and the natural history is poorly described. It is thought to give rise to pulmonary carcinoids (PCs) (>5mm) or tumourlets (≤5mm).

#2129 Phosphohistone H3 (PHH3) Immunohistochemical Staining Outperforms Conventional H&E Mitotic Count in Classifying Pulmonary Carcinoids

Introduction: Pulmonary carcinoids (PC) are well-differentiated NETs and are classified as typical carcinoid (TC) and atypical carcinoid (AC). Despite the fact that TC and AC exhibit significant differences in patient survival, their classification depends on relatively subtle differences in mitotic count (MC). Although careful counting of mitotic figures (MF) is essential, it is a very subjective task, time-consuming and lacks of sensitivity and interobserver reproducibility, due to selection bias of the hot spots, heterogeneous distribution of MF, difficulty in distinguishing MF from similar chromatin changes (i.e. in apoptotic cells or due to crush, karyorrhectic debris, pyknosis or apoptosis).

#2123 Large Cell Neuroendocrine Carcinoma (LCNEC) Associated with a Dysplastic Sessile Serrated Lesion (SSL) and Deficient Mismatch Repair (MMR) Protein: A Case Report.

Introduction: Colorectal poorly differentiated neuroendocrine carcinomas (NECs) are rare, but extremely aggressive. The mechanisms of their carcinogenesis and aggressiveness are still largely unknown. Recently Nobuyoshi Takizawa showed that the molecular features of colorectal NECs are similar to those of adenocarcinoma and not to those of NETs and they were more evident in small cell NECs than in large cell NECs. This is supported by combined cases with conventional adenoma/adenocarcinoma and NECs. Stelow et al showed that DNA mismatch repair proteins were intact in 14/15 colorectal small cell NECs. Two cases of LCNECs arising from SSL have been reported so far in the literature.

#1415 Detection of SSTR2 and 5 Expression on Circulating Tumour Cells in Neuroendocrine Tumours

Introduction: Neuroendocrine tumours (NET) overexpress somatostatin receptors (SSTR) which can be targeted for therapy with somatostatin analogues (SSA) or radionuclide treatment.

Abstract Submissions in 2022

Abstract submissions for 2022 will open in September 2021!

 

The 19th Annual ENETS Conference in 2022 will provide the principal platform for NET researchers around the world to present their latest findings. ENETS will select the best abstracts submitted in both clinical and basic science and present these in sessions within the framework of its scientific programme.

 

Participants of the ENETS Virtual Conference 2021 can now access the abstract booklet, e-posters and videos, the poster carousel, and more via My ENETS.
