#4564 Vasculogenic mimicry in neuroendocrine tumour across different primary sites

Introduction: Anti-angiogenesis treatments targeting VEGFRs, including Surufatinib and Cabozantinib, etc. showed better efficacy for pancreatic neuroendocrine tumours (NET) than NET of other primary sites. Recent clinical trial targeting tumour necrosis factor receptor-associated protein-1, leading to inhibition of vasculogenic mimicry (VM) showed contrary results to current VEGFRs-targeted treatments. However, VM of NET across different primary sites are yet to be understood.

#4523 Preoperative evaluation of tumour border using radiomics and its surgical guidance in pancreatic neuroendocrine tumours

Introduction: Pancreatic neuroendocrine tumours are a heterogeneous group of tumours originating from peptidergic neurons and neuroendocrine cells with variable survival outcomes. Surgical resection is the mainstay of treatment. However, there is an ambiguous insight into the real need to execute the standard surgery in small pancreatic neuroendocrine tumours. The tumour border is a powerful determinant of survival prognosis in many tumours and is often used as a safety guarantee for parenchyma-sparing resections. However, there are no studies evaluating tumour border with or without preoperative imaging in pNETs.

#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.

#4372 CVM-005: A multicentre, single-arm, phase IIa study of CVM-1118, a novel oral anti-vasculogenic mimicry (VM) agent, in patients with treatment-refractory advanced neuroendocrine tumours (NET)

Introduction: NETs are highly vascularised tumours and a viable target for anti-VM therapies. CVM-1118 is an anti-tumour agent with multiple MOAs, including disruption of VM networks and induction of apoptosis via targeting mitochondrial TRAP1 protein.
