#1273 Tissue Prognostic Markers in Pancreatic Neuroendocrine Tumours
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.

#618 Angiogenic Characteristics of Radiological Hypervascular Liver Tumors (NET, Hepatocellular Carcinoma) and Hypovascular Colorectal Liver Metastases and Their Microenvironment.
Introduction: Tumor and microenvironment are important for tumor progression. Liver tumors can be hypervascular or hypovascular during the arterial phase of cross-sectional imaging.

#905 Cancer-Associated-Fibroblasts in Neuroendocrine Neoplasms: A Role in Cancer Progression
Introduction: Cancer-associated-fibroblasts (CAFs) secrete soluble factors that enhance tumor growth and invasion. Neuroendocrine tumor (NET) cells recruit fibroblasts within the lesional sites.

#1181 Significance of Ectopic Lymph Node-Like Structures in Neuroendocrine Tumors of the Small Bowel
Introduction: The formation of extranodal tertiary lymphoid follicles and lymphoid cell aggregates has been described in nonmalignant conditions including autoimmune diseases and chronic inflammation as well as in cancer. Tumor-induced lymph node-like structures (LLS) participate in the host’s antitumor immune response by driving intratumoral immune cell priming

#1219 Changes in Neuroendocrine Tumor Microenvironment with WHO Tumor Grading
Introduction: The microenvironment of neuroendocrine neoplasias (NEN) in view of tumor grading (WHO classification of 2000 und 2010) has not yet been validated. Both classifications distinguish between well and poorly differentiated neuroendocrine tumors, including proliferation rate, mitotic index and histomorphology. The WHO classification of 2000 further evaluates tumor location, size, angioinvasion, invasion of the muscle layer, functionally active tumors and metastases.

#2684 Tumour-Infiltrating Neutrophils Predict Poor Survival of Non-Functional Pancreatic Neuroendocrine Tumour Patients after Curative Resection
Introduction: Non-functional pancreatic neuroendocrine tumours (NF-PanNETs) are steadily increasing in prevalence and present several clinical challenges.

#2199 Systematic Evaluation of the Immune Microenvironment of Neuroendocrine Tumors (NET)
Introduction: Immunotherapy is being explored in many tumour types with encouraging results, but
its role in the management of NET is yet to be defined.

#2693 The Distinctive Character of Micro-Vasculature and Immune Cell Infiltration in Cystic Pancreatic Neuroendocrine Tumors
Introduction: Hypervascularity is main character of pancreatic neuroendocrine tumors (PanNETs), cystic PanNET (CPanNET) are unique type of PanNETs for which the microenvironment remains unknown.

#466 HIF-1a Determines the Metastatic Potential of the GEP-NET Cell Line BON-1
Introduction: Intratumoral hypoxia is a hallmark of solid tumor formation and a negative predictor of patient survival. Adaptation to hypoxia is mainly achieved by the transcription factor HIF-1a, which is upregulated in a diverse range of human and experimental tumors and their metastases. HIF-1a target genes have been implicated in the induction of invasion and metastasis. However, HIF-1a’s tumor-supporting action depends on cell type and microenvironment and the precise role of HIF-1a for the pathogenesis of neuroendocrine tumors (NET) is largely unknown.
