#4424 Tumour-derived apolipoprotein E induces tip endothelial cell to remodel tumour stroma ratio and promote pancreatic neuroendocrine tumour progression

Introduction: Current clinical trials have shown that single-targeted matrix administration does not improve patient prognosis. The investigation of targeted matrix administration in combination with other therapies is crucial for effectively managing TSR in pNETs.

#3974 Small extracellular vesicles miR-183-5p derived from highly invasive pancreatic neuroendocrine tumors reprogram macrophages towards SPP1+ macrophages

Introduction: Highly-metastatic (HM) pancreatic neuroendocrine tumors (pNETs) are characterized by an early occurrence of lymph node and liver metastases and a poor prognosis. Single-cell sequencing analysis showed that HM pNETs had remarkable infiltration of SPP1+ macrophages, which were involved in cell migration, angiogenesis and small extracellular vesicles (sEVs).

#3935 Single-cell sequencing reveals the heterogeneity of pancreatic neuroendocrine tumors under the pattern of genomic instability and histological grading

Introduction: Non-functional pancreatic neuroendocrine tumor (NF-Pan-NET) is a kind of highly heterogeneous tumors. Histological grading is the key factors affecting the prognosis of patients and instructive in guiding treatment and assessing recurrence in NF-Pan-NET. 90% of NF-Pan-NET are grade G1 or G2, leading to an unpredictable clinical course that varies from indolent to highly malignant. Approximately one-third of patients without CNV alteration and the prognosis of these patients are better than that of patients with CNV alteration. Therefore, probing the heterogeneity of tumors based on histological grading and CNV variation is crucial.
