#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.

#4146 Anticancer activity of Cabozantinib and Temozolomide in cell lines derived from lung carcinoid and pancreatic neuroendocrine tumors

Introduction: Limited therapeutic options are available for patients with advanced neuroendocrine neoplasms (NENs). Cabozantinib (CBZ), a tyrosine kinase inhibitor including c-MET pathway, and Temozolomide (TMZ), an alkylating agent enhancing the anti-angiogenic effect of CBZ, are emerging as promising treatments in NENs.

#3883 Immune landscape in mixed neuroendocrine-non neuroendocrine neoplasms (MiNEN)

Introduction: A mixed neuroendocrine-non neuroendocrine neoplasm (MiNEN) is a novel defined rare entity, made up of two morphologically distinct neoplastic components; one neuroendocrine type (NEN), and the other one non-neuroendocrine type (nNEN). Neuroendocrine differentiation of tumors is thought to influence the tumor microenvironment (TME) through the secretion of various hormones or growth factors.

#3670 Response to peptide receptor radionuclide therapy in pheochromocytomas and paragangliomas – A systematic review and meta-analysis

Introduction: Peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATATE and 90Y-DOTATOC has shown efficacy in the metastatic setting of pheochromocytomas (PCCs) and paragangliomas (PGLs) where no standard therapies have been established.

#3483 A phase II single arm interventional trial evaluating the activity and safety of combination between CABOzantinib and TEMozolomide (TMZ) in lung and GEP-NENs progressive after SSAs, everolimus, sunitinib or PRRT-CABOTEM

Introduction: Cabozantinib (Cbz), a tyrosine kinase inhibitor, and Temozolomide (TMZ), an alkylating agent, show relevant clinical implications in neuroendocrine neoplasms (NENS). In glioma patients, the combination of Cbz and TMZ was well tolerated even with the addition of radiotherapy. It is possible to hypothesize a synergistic combination of Cbz and TMZ. Cbz, through the inhibition of the c-MET pathway, could enhance the sensitivity of NENs to TMZ. In addition, the intermittent metronomic schedule of TMZ has a proven anti-angiogenic activity that could be additive and/or enhance the anti-angiogenic effect of Cbz.
