Introduction: Immunohistochemical expression of synaptophysin (SYN), chromogranin (CgA) and cytokeratin are essential for diagnosis of NENs. Non-NENs, however, may occasionally also express NE-markers and cytokeratin and cause diagnostic difficulties.

#2198 PD-L1 Expression and Its Clinical Relevance in Neuroendocrine Tumors of the Lung
Introduction: Immune checkpoint regulation seems to be crucial for nonneuroendocrine lung cancer patients. However, little is known in lung neuroendocrine tumors.

Introduction: The classification of lung neuroendocrine neoplasms (Lung-NENs) according to the WHO classification 2010 for GEP-NENs, including a provisional category for Lung-NET G3 with Ki67 >20%, may have prognostic implications.

Introduction: Prognostic impact of well differentiated pancreatic neuroendocrine neoplasms (PanNENs) with a Ki67 >20%, provisionally called NET G3, needs to be validated and compared to poorly differentiated neuroendocrine carcinomas (NECs). Moreover, the frequency of NET G3 among gastrointestinal NENs (GI-NENs) has so far not been studied.

Introduction: A common classification has been used for NET in gastrointestinal tract (GI-NET) and pancreas (P-NET), but heterogeneity has been reported in high grade tumors; well-differentiated G3 (WDG3), poorly differentiated NEC (NEC), and mixed adenoneuroendocrine carcinoma (MANEC).
