DLL3 Expression in Neuroendocrine Neoplasms – an overview
Updated 20th August 2025 Background - Conventional therapeutic targets for neuroendocrine tumours (NETs) include somatostatin receptors (SSTRs), mammalian Target of Rapamycin (mTOR), Vascular Endothelial Growth Factor (VEGF), and tyrosine kinases. These pathways are crucial for tumour growth, survival, and angiogenesis. The most well known is SSTRs given that most NETs express these and allows targeted therapies such as somatostatin analogues (SSA) and peptide receptor radionuclide therapy (PRRT) to be used. Other targeted therapies like everolimus and sunitinib, which inhibit mTOR and tyrosine kinases respectively. Sunitinib also targets VEGF as does cabozantinib. For neuroendocrine carcinomas (Grade 3 poorly differentiated), targeting has…
