#3089 Mixed Large and Small Cell Neuroendocrine Carcinoma of the Endometrium: A Case Report and Literature Review

Introduction: Neuroendocrine carcinoma (NEC) is an extremely rare subtype of endometrial cancer which is usually seen among perimenopausal or postmenopausal women. It runs an aggressive course and posts a clinical challenge due to limited treatment options available.

#2941 Mixed Urothelial and Neuroendocrine Carcinoma of the Urinary Bladder: Case Report and Literature Review

Introduction: Neuroendocrine tumors (NETs) comprise <1% of all bladder tumors,characterized by poor prognosis. These tumors may be either pure or impure, intermixed with urothelial carcinoma. There is currently no therapeutic consensus. We report the case of primary impure neuroendocrine carcinoma (NEC).

#2855 Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas

Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

#2725 Upfront Surgery in Patients with High-Grade GEP NEN and MINEN: A Nordic Multicenter Study of 201 Patients

Introduction: Surgery is the principal treatment for loco-regional gastroenteropancreatic (GEP) neuroendocrine tumors (NET). However, whether surgery is beneficial in high-grade neuroendocrine neoplasms (NEN) and mixed neuroendocrine-non neuroendocrine neoplasms (MiNEN) is not known.

#2259 Clinical Characteristics, Treatment Outcomes and Potential Novel Therapeutic Options for Patients with Prostatic Neuroendocrine Carcinoma

Introduction: Prostatic neuroendocrine carcinomas (PNECs) are rare tumors with poor prognosis. While platinum and etoposide based chemotherapy regimens (PE) are commonly applied in first-line for advanced disease, clinical-grade evidence for treatment options in second-line and beyond is very limited.
