JO - Endocrine pathology VL - 36 IS - 1 SN - 1046-3976 CY - New York, NY PB - Springer M1 - DKFZ-2025-00653 SP - 9 PY - 2025 AB - Delta-like ligand 3 (DLL3) is frequently expressed in pulmonary small cell neuroendocrine carcinoma (SCNEC) and has emerged as a promising therapeutic target. However, limited data on DLL3 expression in other neuroendocrine neoplasms (NEN), such as extrapulmonary SCNEC, large cell neuroendocrine carcinomas (LCNEC), mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN), gastroenteropancreatic neuroendocrine tumours (GEP-NET), and pulmonary carcinoids, impedes an estimation if other types of NEN might be suitable candidates for anti-DLL3 therapies. We evaluated DLL3 expression in 1294 NEN and 479 non-neuroendocrine carcinomas, correlating the findings with histological subtypes, tumour localisation, and overall survival (OS). Furthermore, we explored the concordance of DLL3 expression during metastatic progression in 67 paired primary NEN and metastases. DLL3 expression was significantly higher in NEC (64.0 KW - Humans KW - Neuroendocrine Tumors: pathology KW - Neuroendocrine Tumors: metabolism KW - Neuroendocrine Tumors: mortality KW - Carcinoma, Neuroendocrine: pathology KW - Carcinoma, Neuroendocrine: metabolism KW - Carcinoma, Neuroendocrine: mortality KW - Lung Neoplasms: pathology KW - Lung Neoplasms: metabolism KW - Male KW - Female KW - Intracellular Signaling Peptides and Proteins: metabolism KW - Intracellular Signaling Peptides and Proteins: biosynthesis KW - Middle Aged KW - Aged KW - Membrane Proteins: metabolism KW - Membrane Proteins: biosynthesis KW - Biomarkers, Tumor: analysis KW - Biomarkers, Tumor: metabolism KW - Adult KW - Cohort Studies KW - Aged, 80 and over KW - DLL3 (Other) KW - Neuroendocrine carcinoma (Other) KW - Neuroendocrine neoplasms (Other) KW - Neuroendocrine tumour (Other) KW - DLL3 protein, human (NLM Chemicals) KW - Intracellular Signaling Peptides and Proteins (NLM Chemicals) KW - Membrane Proteins (NLM Chemicals) KW - Biomarkers, Tumor (NLM Chemicals) LB - PUB:(DE-HGF)16 C6 - pmid:40153138 DO - DOI:10.1007/s12022-025-09854-3 UR - https://inrepo02.dkfz.de/record/300176 ER -
