Tissue Prognostic Markers in Pancreatic Neuroendocrine Tumours Abstract #1273

Introduction: Pancreatic neuroendocrine tumours (pNETs) are a rare, heterogeneous class of neoplasms, with a rising incidence. Prognosis is variable with 5-year survival as low as 16% in inoperable tumours.
Aim(s): The role of the microenvironment in influencing prognosis is poorly described is the focus of this research.
Materials and methods: A thorough literature review has performed to identify important aspects of pNET microenvironments. A database of 131 patients with pNETs has been generated including all clinical, histopathological and survival data. Tissue Microarrays (TMAs) have been produced from paraffin-embedded primary and metastatic tumour tissue. These have been immunohistochemically stained for immune, stromal, signalling and vascular markers to identify prognostic markers.

Introduction: The presence of lymph node metastases is one of the most powerful predictor of recurrence after surgery for pancreatic neuroendocrine neoplasms (PanNENs), but the most appropriate nodal staging for PanNENs is unclear.

#1630 The Positive Expression of PD-L1/PD-1 in Gastroenteropancreatic Neuroendocrine Neoplasias Correlates with Prognosis
Introduction: The incidence of Neuroendocrine Neoplasias (NENs) is increasing and their pathological characteristics, varied between races. However, the epidemiology of GEP-NENs in Chinese patients remains poorly characterized especially for the expression of important immune checkpoint protein PD1 and PD-L1.

#1148 Ki67 as a Prognostic Marker in Neuroendocrine Tumours: A Systematic Review of the Literature and Quantitative Synthesis of 5 year Survival Data
Introduction: The ENETS guidelines classify Gastroenteropancreatic Neuroendocrine Tumours (GEP NETs) according to the histological assessment of tumour mitotic count or Ki67 labelling index (LI) on paraffin-embedded tissue, because proliferation rate has been shown to strongly correlate with prognosis. Since the guidelines were published, Ki67 has been established as the more reproducible measure, and further large case series have been reported.
