#4661 Comparison of preoperative chemotherapy and radio ligand therapy on prognosis after surgical resection for locally advanced or hepatic metastatic pancreatic neuroendocrine tumours

Introduction: The role of preoperative treatments in improving the rate of radical resection and survival of either locally advanced (LA) or hepatic metastatic (HM) pancreatic neuroendocrine tumours (panNETs) is unclear.

#4646 Dysregulated miRNA in patients with GEP-NEN and potential role as circulating biomarker

Introduction: Neuroendocrine neoplasms (NENs) are a class of rare and molecularly extremely heterogeneous tumours. NENs arise predominantly in the gastrointestinal (GEP) and pulmonary tracts but can also involve thyroid and breast. NENs often present with non-specific symptoms and lack early specific biomarkers, leading to frequent metastatic diagnoses and primary site challenges.

#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.

#4622 Elucidating the role of high mobility group box 3 (Hmgb3) during progression and response to radiation therapy in pancreatic neuroendocrine tumours

Introduction: We have recently demonstrated that HMGB3 is upregulated during the pancreatic neuroendocrine tumours (PanNETs) transition via dedifferentiation from a relatively benign molecular subtype to an aggressive and highly metastatic molecular subtype. HMGB3 expression has recently been linked to resistance to therapy, metastasis, and poor prognosis in patients with various solid cancers.
