#4629 Identification of putative master regulators in pancreatic neuroendocrine tumours using gene expression data and network inference

Introduction: Pancreatic neuroendocrine tumours (pNETs) are a heterogenous group of pancreatic malignancies with a unique biology and pathophysiology. Tumour grade and extension are commonly used for prognostic determination. Current pathologic grading system needs regular updates to refine prognostic classification. Genomic screening may provide more objective classes and reflect tumour biology.

#4513 Predictive value of different PD-L1 immunohistochemistry clones for immunotherapy efficacy in neuroendocrine tumours: A case series

Introduction: In the ZS001 clinical trial, we observed that NET patients with higher PD-L1 expression levels were more likely to benefit preferentially from immunotherapy.

#4456 Characteristics and clinical outcomes after endoscopic or surgical resection of localised sporadic type III gastric NETs: A national study from the French Group of Endocrine Tumors and ENDOCAN-RENATEN network

Introduction: Type III gastric neuroendocrine tumours (gNETs) are rare indolent tumours with increasing incidence. Endoscopic resection has recently been described to be a safe strategy to remove small, localised type III gNETs.

#4393 Surufatinib plus trans arterial embolisation (TAE) vs. surufatinib monotherapy in neuroendocrine tumour with liver metastasis: Updated results from the prospective, randomised, controlled trial

Introduction: The liver is the main metastasis site for NETs. Surufatinib (SUR), an oral TKI, is standard therapy for advanced NETs. TAE is the primary local intervention for unresectable hepatic NETs.
