#4449 Treatment of MiNEN with peptide receptor radionuclide therapy

Introduction: Mixed non-neuroendocrine and neuroendocrine neoplasms (MiNENs) of gastrointestinal tract are rare tumours with characteristic histological features include at least 30% of both neuroendocrine and non-neuroendocrine components of the whole neoplasm. They are usually treated with surgical resection and chemotherapy in advanced disease. However, there is scarcity of data for the use of peptide receptor radionuclide therapy (PRRT) in these tumours.

#4396 Hypoxic microenvironment in neuroendocrine tumours

Introduction: The hypoxic microenvironment is a hallmark of many solid tumours, including neuroendocrine tumours (NETs). Hypoxia plays a crucial role in tumour progression, metastasis, and therapy resistance. However, the specific mechanisms by which hypoxia influences NET behaviour remain poorly understood.

#4395 Mechanisms of drug resistance in neuroendocrine tumours: A basic research study

Introduction: Neuroendocrine tumours (NETs) often show resistance to chemotherapy and targeted therapies, leading to treatment failure. However, the molecular mechanisms underlying this resistance remain poorly understood.

#4319 Everolimus combined with orlistat inhibits the development of neuroendocrine tumours by inhibiting the mTOR-PI3K-Akt signalling pathway

Introduction: Everolimus, an mTOR inhibitor, has demonstrated efficacy in NET treatment. Orlistat, used primarily for obesity management, inhibits fat absorption. This study investigates the potential synergistic effects of Everolimus combined with Orlistat on the development of NETs.

#3989 Hypoxia upregulating ACSS2 enhances lipid metabolism reprogramming through HMGCS1 mediated PI3K/AKT/mTOR pathway to promote the progression of pancreatic neuroendocrine neoplasms

Introduction: Pancreatic neuroendocrine neoplasms (pNENs) are relatively rare. Hypoxia and lipid metabolism-related gene acetyl-CoA synthetase 2 (ACSS2) is involved in tumor progression, but its role in pNENs is not revealed.
