#4457 Primary mixed hepatocellular carcinoma-neuroendocrine carcinoma: A case report

Introduction: Mixed epithelial neoplasms (MiNENs) are characterised by the coexistence of neuroendocrine and non-neuroendocrine components within a single tumour, each discernible histologically and immunohistochemically, with a minimum tumour proportion of 30%. Primary hepatic MiNENs are exceedingly rare entities.

#4455 Multicentric ENETS morphological and molecular appraisal of high-grade gastroenteropancreatic neuroendocrine neoplasms (HG-GEP-NEN): Distinguishing NET G3 from NEC

Introduction: HG-GEP-NEN are classified into neuroendocrine tumours grade 3 (NET G3) and neuroendocrine carcinomas (NEC). This distinction is crucial as it affects patient prognosis and treatments but can be challenging.

#4106 Overview of 609 cases of neuroendocrine neoplasms

Introduction: Neuroendocrine neoplasms are rare tumors that originate from peptideric neurons and neuroendocrine cells, have neuroendocrine functions and express neuroendocrine markers, and early identification and treatment can significantly improve the prognosis of patients.

#4104 Promising outcomes with surufatinib-vinorelbine combination therapy in lung cancer with neuroendocrine differentiation

Introduction: Lung cancer (LC) remains one of the most prevalent and deadly cancers worldwide. Neuroendocrine differentiation (NED) is observed in 25-33% of LC cases. NSCLC patients with NED (NSCLC-NED) often have worse outcomes, resembling SCLC behaviour.

#3755 Large cell neuroendocrine carcinoma of the breast

Introduction: Primary neuroendocrine breast carcinomas are rare and little-known tumors. They account for only 2 % to 5 % of breast cancers. Diagnosis is based on neuroendocrine architecture associated with the expression of neuroendocrine markers.
